Hi,
I got a few spare androids' and i'm considering giving them to my kids (11 and 12) to play around with it and enjoy the android experience. however I don't want them being able to put 3rd party applications. how do i go about removing the option of "unknown sources" and maybe wifi from the settings.apk.
I'm not new to java and xml but sort of new to android development, I've tried several ways to remove it from the apk only (ark, ddx, baksmali, apksign) I did it in so many ways that i can't remember them all. I've also tried to decode the apk with apktool, ddx, baksmali, and creating a new project from existing source in eclipse, and I couldn't figure out what parts I have to modify to get it working (i kept on getting errors in eclipse so i wasn't even able to compile and test it in DDMS-eclipse).
Also i would like to know if maybe it is necessary to port the whole kernel source into eclipse?
I've searched all over the internet for a information for this specific thing and I couldn't find anything.
Btw, I'm using nix lucid.
Thanks In advance.
any help would be appreciated!

I know, the problem is not the market, i can pull it out from the phone with adb in a second w/o superE, but they can still install stuff on it with a sd card, and I would hate to not put in a file browser on the phone.
I think it would be a good idea to make a rom that's made for kids, for playing games and stuff without me worrying about it.
I'm sure that they will try to figure out a way to get around the "no market on the phone" and I should not underestimate a kid (even a 12 year old). I've seen him getting around lots of technological obstacle's.
I think that the world could use a kid's version of android, you know, get them hooked when they're young. The last thing i would like to hear from my kids is talking about iPhone or Windows. We're all linux in our house
Interesting. I too gave Magics to my 11 & 12 yr olds, one without a data plan and the other without a SIM at all. I think the right way might be multiuser like we already do on the desktops. Sudo would be a nice touch but I'd be happy to login as admin to install or whatnot.
Multiuser is something I'd like to see anyway with most or some settings on a per user basis. Or at least just for security, normal login can't do critical tasks that might cause issues. I think we'll hear about this again once we hear about some seriously dangerous apps/scams/viri on the phones.
In the meantime your best bet is education and rules about what can and can't be done. Then once per week or so you take the phone and check things out, update as needed, etc. So far my kids have little interest in breaking the rules and are happy browsing the market for fun things.
I think the only way to achieve this is to download the AOSP, edit the sources to remove the options and then compile your own ROM.

well, it is just a nix and SUDO should be possible, but setting this up is a quite a project and I don't think this is a one day project.
As for educating, I think they know right from wrong and I don't think that they will willingly break the rules, the market however is full of apps that are not meant for young kids..... what do you think they're going to do when they bump in to one of those apps? .
Actually what i wanted to do is to give them a phone with a line and no data plan so they can play games or watch movies, If the kids want to use the internet, there are more than enough boxes at home they can use. This phone is strictly for voice text and games.
What I want to accomplish in general, is having a child safe phone, and have the other parents here who want their kids to have to have an android, enjoy it. My way of giving back to the community.
But to have a phone that will be suitable for the purpose (not just for my kids) the data has to be completely disabled, and wifi is going to be the issue. putting on an encryption on wifi is a joke, ever heard of aircrack? I'm sure there are lots of determined horny 15 year olds that will get around that. (am i paranoid?)

That's exactly what i want to do. The question is how do I do it?
Again, I'm not a complete noob, I just never played around with android as an OS. so if I can have the first push here here what I'm supposed to do to start this I would really appreciate it.
As I've said in my first post, I tried a few things and i couldn't get it right. what part of this don't i get??
Thanks a lot.
well your not even going in the right direction..
do you have an IDE with compiler and the android SDK all set up? then you can check on dferrera post on how to compile android from source... its listed in this forum.. please search
if your not a programmer or have no idea what classes - functions etc are then this might now be an option for you that is something you can be instructed on
you are going to need to learn to compile android from source and modify it, this is a very big task mate - be prepared, and no one can answer all the questions for u

Thanks for the reply, but i can't seem to get java5 working on 10.04 (the 10.04 repos have only java6 but i did add the old repos and ran in to some issues), I had it working on 9.04 though. anyone made it run on 10.04? or should I downgrade (or run it in VB) to 9.04/.10?

Hiding Wifi and other things should be quite easy task, but... how do you want to protect against system reinstallation? They could download any ROM from internet and install it in just 10 minutes. Backuping is easy too, so they could have 2 systems installed and switch between them when their dad comes home.
Android phones aren't desktops. You can't have root and don't give it to other users of a device.
Mod. edit: not dev related, moved to general
I wouldn't want to hide WiFI, the device is useless without connectivity, much cheaper toys out there for that if I wanted stand alone.
My two children each have a Magic and this is my experience, none of the worries that many parents seem to fear. They are well behaved and so far no problems and they are ready for 2.1 since 1.5 is just too confining even for them. Education goes a long way.
The best choice I made was to not put a SIM in one of the phones. WiFI is ideal since she is nearly always in a zone. This has gotten her used to IM instead of texting. Same effect but costs nothing. A SIP app works almost as well as SIM voice. Someday I'll do a data only SIM so she has total coverage, she'll understand that heavy data is to be done over WiFI and cell data is for VoIP and for times when it is really needed and can't wait.
However it would be nice if there was a limited setting requiring admin password for certain functions. But really, there hasn't been any problems but my kids might be grateful enough to not abuse the rights I give them. Best advice besides education if they are very young is to not SIM until after they get into the alternatives and not be addicted to texting. The older one has learned to watch her usage patterns and has to pay if she goes over budget.

You are right, but one of the later steps I thought about would be a custom boot and custom or no recovery. But I will figure that out later in the project.
But i will probably change my direction on this (wifi etc.) based on what you guys say.
Let me start off by saying I am not a developer. And Im not too familiar with Linux either. Just goes to show that this isnt too difficult
To get ubuntu on the Atrix please go here first:
[MOD] Full Linux (Debian) inside WebTop! v0.2.6 [2011/07/07] [14.15 GMT+2:00] - xda-developers
Follow the steps. Must have CMW installed, rooted etc.
I was unsuccessful with webtop2sd. You might have good results with it, but for me it didnt.
Once you flash this cmw file, reboot you phone and enter into webtop (if you need the HDMI hack, you will find that on XDA). You will now see 3 new icons. Leafpad, Lxterminal, and a penguin. Click on the penguin, and you it will say found image. Click ok.
If your unfamiluar with linux, this will look french to you. Once it launches (the first time after reboot will take some time, be patient). Hit enter, enter again and scroll down to Shells, then hit enter on Bash. Now this is where the fun begins.
Enter synaptic. If that doesnt work you might need to install it. apt-get install synaptic. After thats opened search for gnome-panel, right click and select "mark for installation". Hit apply and go for a coffee. This will take a long time, and make sure your on wifi. This is a huge download.
Here is a list of working applications so far :
Epiphany web browser
Epiphany IM
Evolution Mail
Iceweasle
AbiWord
GNU image manipulation
All of the games
Im working on getting usb-to-ethernet dongle working.I can see it, just cant get access to it.
Almost all of the pre-installed applications with gnome work. EXCEPT sound. This is driving me nuts. I am unable to find a sound driver (gstreamer) that works. If anyone here figures it out let me know. And if anyone out there have programs that work let me know. I can always add it to the list. Im very green to Linux, and just playing around at this point. Im no developer, and most of your questions can be answered on XDA forums.
I have the same setup, and you can add openoffice.org and geany packages to the "functional" list. I use openoffice's writer every day and have found no missing functions. Geany is working, but does not build and compile, so it's basically a color-coded text editor (still useful for note-taking my language classes). I did NOT use synaptic to get these. I simply used the bash script (in the same manner you described for your synaptic install) to apt-get install openoffice.org and geany respectively. Nice thread,

Where you able to get sound working??

My sound through the Webtop is functional, yes. I'm not sure if you were talking about gnome-specific apps (I wouldn't know, because I'm not using gnome panel), but anything through mobile view or iceweasel (not including flash) plays stereo through the Webtop. I didn't do anything special to get it working, it always just has. I hope you figure out your problem.

With epiphany did you encounter a problem where it uses xulrunner-1.9.2 instead of xulrunner-1.9 and fails to start the gecko engine? The epiphany version that is available through synaptic after fixing apt-get dependencies and sources uses xul1.9 once and works right then uses xul1.9.2 every time after that and fails. Epiphany lists both xul versions as deps so i, unsuccessfully, tried to lock xul1.9 and install a fake xul1.9.2. Any help would be awesome.
I did manage to make Webtop2SD work after I created a 4 GB partition on my ExtSD through Webtop2sd partitioning tool.
Here's what I got working (installed through Synaptic):
XFCE4 (full suite)
OpenOffice
GIMP
EPDFViewer
Fillezilla FTP client
VLC Media Player (marginal results)
Ristretto Image viewer
ABE's Amazing Adventure (game with full working sound)
I was hoping to have some sort of ScummVM, MAME and SNES emulator to run, but unfortunately they don't even after a successfull install.
Cheers!

I know it's a bit late for commenting lol. And probably my post may be off-topic. But was your issue the <no sound coming from HDTV via HDMI> one?
I also had this issue in webtop going on for like 3 months (like flashing and reflashing webtop to no end), until I stumbled upon this Motorola forum:
h**p://supportforums.motorola.com/message/330591#330591
(had to mod link because I didn't reach the minimum amounts of posts to allow links -_-)
Basically, if you switch display resolution to anything other than 1280x720, sound will not redirect to HDTV. And as for me, after switching to 1280x720, I had to reboot my Atrix in order to finally have sound . No need to find for drivers.
My sound would work within the Webtop apps from Motorola. But if I wanted to use a Linux MP3 player, watch a video etc there would be no sound. Kept getting a gstreamer error.
Hi g2tegg,
I have Atrix with iBlur ROM. I installed the WebTopMOD zip file using CWM and have the folder with linux image in sdcard-ext. But when I reboot the phone and plg it in Atrix Lapdock I don't see the icons like: penguin etc.
Could you please help.
Got it working !!

Try to reflash the webtop and then the mod again. There is a thread in the developers area I believe called webtop mod v1 or something like that. When I get the chance I will try to dig it up. Driving in a snowstorm at the moment slightly hinders my searchability haha. Good ol Ontario I tell ya
quick question: are these persistent? can I make a desktop icon for these or do I have to apt-get them everytime?
seems counter intuitive to not be able to "hard" install the applications

You dont have to apt-get everytime. The installed applications are on either the phones hard drive or the SD card. Only thing you will have to do is start the gnome panel every session, which is easy enough.

Yeah after tinkering with them for enough time I figured that out!
only question is how do I figure out where they are located on my phone? I can't find a DEBIAN folder anywhere on my device (sd or sd-ext) my webtopmod folder is on my internal storage btw
thanks for the response!
If you use webtopmod's debian chroot (the white shell) they'll be in the linuxdisk file, as it's actualy a filesystem in itself. You won't be able to 'directly' access them. I recommend switching to webtop2SD. I didnt' want to, but everything is native that way and most things run better anyways, I installed xfce4 and got rid of that stupid awn dock at the bottom and put in a little bar. Now it feels like linux!
My apps so far:
OpenOffice 3
XChat
rdesktop (doesn't work, keymap doesn't work)
gimp (not used yet)
Any other useful ones people know of? I don't need an email client... the phone's gmail app is sufficient enough, and if I need more support I'll just use gmail. Kind of wish I could get an updated firefox, or a tun/tap module so i could use hamachi.

I installed chromium, and it's running smoother than firefox ever did. Haven't really had a reason to install anything else, but i think i'm gonna get fxce4 because the current dock at the bottom annoys me

^yeah after using it exclusively for the past day or so it's quite capable but I can also see the limitations of debian through chroot. I'd ideally like to get rid of the webtop all together and just have kde or gnome (i'm not picky, xcfe4 would work for me too)
but I'm assuming if I do webtop2sd I can have ubuntu with gnome installed no problem?
I went through the process of putting all of my gnuSTEP icons on the webtop and it's very much like my current gnuSTEP machine (supremely capable btw when using a debian core) I haven't run into any real problems using the chroot method, save for not being able to put shortcuts on the AWN bar and the occasional, but when I get my lapdock in the mail and start exclusively using this when I'm out and about I'll look into doing webtop2sd. I need to get a bigger sd card too, I have a 16 but I'd rather have a 32 external only for webtop and the 10 or so internal for android I don't listen to music on my android (I own a zune) so 10 should be plenty to just have apps and android

Did you use the jaunty hack to get chromium working?
I successfully installed chromium but every page loads for a second and then crashes. I didn't really look into the chromium hack (I don't think I use jaunty for anything and synaptic/apt-get can get all the repositories I need) but it seemed intensive especially to get flash.
I've found that while firefox has FANTASTIC flash support (like, really good and speedy, no chops) I just end up using konqueror for regular internet tasks. I can't seem to get it to install flash (I don't know how to install .deb packages) but it's speedy for other things and makes an excellent file manager
If you could get chromium without 2.3.5 i'd get it... but 2.3.5 offers what appear to be no benefits at all, correct?
Just kinda scared to have to rebuild from a bricked phone.
Trolling from my ATRIX 4G's XDA premium app, still on the gold medal winner of worst customer satisfaction for the second year in a row! Congrats!
I upgraded to 2.3.5 it has the new firefox, it runs fine from what I've seen
I'm trying to install synaptic by "apt-get install synaptic", but it shows several "Failed to fetch http://ftp.debian.org/debian/......" messages.
How can I fix this?
I am thinking of getting a Nexus 4 (or a Nexus 5 if such a thing appears in the not too distant future) as my first smartphone, with the eventual possibility of running Ubuntu for Android if and when it becomes available. However, for now the only capability I need the phone for is to be able to open up a Linux style command line terminal on the phone where I can ssh into a couple of other Linux based devices I have, via wifi, so I can run some "C" executables that I have written on these other devices. These other devices are running SSH servers. Is this doable? Do I need a special app or a special ROM, etc.
I assume you mean to run the C executable on the remote machine... not the phone itself?
If yes, then: YES, you can do that. And there are many ways to do it.
At the most basic, the only app that you would need is a Terminal Emulator app (several terminal apps are available for free... some are better than others). From that, you can do what you want. Any of the good ones will work just like any other Terminal on a PC.
But there are other apps that will make it easier because typing out commands, on a phone, isn't the funnest thing ever. Copy-pasting commands is an obvious way to make it easier...
But there are even easier ways than that...
ConnectBot (ssh-agent-patch) app would allow you to ssh into a remote host with a single tap (even using public-private key authentication if you want). Then you can run your ./command (or copy-paste it).
You can even VNC into a remote host and control it graphically (assuming a VNC server is running on the host machine).
You can even go the other way too... you can run an ssh server on the phone and access it from your PC.
Like all ssh capabilities, all of this can be done over the internet too, you aren't limited to WiFi LAN.
Also, on all of my file explorers (on all of my computers AND my Phones) I've made shortcuts for easy file sharing too (all using pub/private key authentication for security). Not only does that make file transfers super easy no matter what machine I have my hands on at the moment, but it also makes my desktop PC at home my own personal cloud server to my phone. Who needs dropbox?
Basically anything you can do with ssh on a computer, it can be done on an Android phone.
ps... if you re-compiled your C executables for the Android system... you could even run them natively on the phone.

Yes.
Fantastic, thanks for the detailed answer. I wanted to know right away before I wasted my time, but now am googling around for all the details. I have a raspberry pi running Debian that I need to communicate with and it is headless (No monitor, keyboard, etc., just a wifi dongle) so this would be perfect. I also have desktop computers that run a bunch of OS's (Centos, Scientific Linux, Fedora, Ubuntu, etc) that I might want to connect to.
From what I understand, all of that can be done without modifying the phone (rooting, etc.), correct?
However, down the road I may want to try and root it anyway, because the bigger set of Linux commands offered by Busybox would nice. I have been putting off getting a smartphone because of the cost, but the Nexus 4 with something like straight talk is the same monthly price as my 400 minutes of just talk with Verizon, so it is time. The coverage and uptime with Verizon is really good, but the costs are just not keeping up with the times.

good question.
I don't know with absolute certainty what functions would require root (I always root right away... so I don't ever think about it... like you said... additional functions... and I forget about it).
Basic, ssh-client functions should not require root. Running the ssh-server on the phone, that I mentioned, certainly does require root though. I know that my Terminal Emulator and File explorer apps have root access, but root is not needed just for the ssh-client functions (I am pretty sure).
Rooting on the nexus 4 is pretty easy. Rooting does require the installation of a custom recovery (at least temporarily). That is something that sounds like it would take someone like a you only a few minutes to do (not counting the time you would likely spend reading about it before hand... and installing the android sdk on a PC). Certainly, no other mods other than rooting would be needed.

Great, I will probably just root the phone after using the phone for a while; I have zero experience with smartphones, plus I want to make sure that the phone works properly. The important thing is that it will do exactly what I need it for.
Last question. I see there are several guides for rooting and unlocking the bootloader.....Any recommendation of which one to use? I see that the one written by Jubakuba "Ultimate Nexus Root Guide" has pointers to urls that are broken (Therefore many critical steps are missing), and apparently it has been that way for quite a while.
I started looking for what I thought the best guide... but I gotta do some stuff... I will be back in a couple hours (hopefully with a good suggestion).
I will piece together a guide tomorrow morning from all the various "how-to" guides out there for you. So many of them are geared towards Windows users, and they start babbling about installing and removing drivers and stuff that you won't bother with in Linux. But I need sleep, right now. It'll just be some copying and pasting from a few of them out there. It shouldn't take long.

It's not necessary to go through all of that; I thought there was maybe one document that a lot of people were using. It is really up to me to start reading up on the subject.
Just bit the bullet and placed an order for the Nexus 4 before it is out of stock again.
Found some simple instructions for unlocking and rooting the Nexus 4:

I just ran across this, and thought about you... looks like a nice new SSH client. I've never used it. But Jerry at Android Central is a pretty serious Linux nerd, so I do put some stock in his recommendations. Just thought I'd throw it out there for you to see.

Well, I had the phone for a couple of weeks and I think I turned it on twice. I really didn't get addicted and start to install apps until I used the GPS feature for a long trip I took yesterday. First time using a GPS....Yeah, just a little behind the times.
So, without rooting, today I installed the following apps which gives me everything I need:
ConnectBot. Works great and allows me to ssh to my Linux boxes.
Terminal Emulator. For basic command access.
FreebVNC. Has a secure tunnel feature built in, so you don't have to go through the whole two step process of setting up a tunnel and then running VNC through the tunnel. Also, it has a zoom feature, access to special keys and mouse emulation.
Wifi Analyzer. Gives you access points, signal strength, etc. There was another app that I added to that app to easily connect to the access points.
Fing. Network Info like mac addresses, etc.
Still will root eventually and install Busybox. However, now that I can access my raspberry pi remotely, my priority is to finish writing my software programs and building electronics for a project that uses that little ARM computer.

I am thinking of getting a Nexus 4 (or a Nexus 5 if such a thing appears in the not too distant future) as my first smartphone, with the eventual possibility of running Ubuntu for Android if and when it becomes available. However, for now the only capability I need the phone for is to be able to open up a Linux style command line terminal on the phone where I can ssh into a couple of other Linux based devices I have, via wifi, so I can run some "C" executables that I have written on these other devices. These other devices are running SSH servers. Is this doable? Do I need a special app or a special ROM, etc.

For a ssh client, try ConnectBot. I have been using this since the G1 came out for work (Sys Admin) and home.
For a better keyboard, check out Hacker's Keyboard.

As mentioned above, I already installed ConnectBot and it has nice features. However, I am interested in the keyboard (keys in the right place, Crtrl/Tab/Esc keys, etc.), so I will be installing that next.
Yep, ConnectBot is the old standard (if there is such a thing in Android world). I use it.
I've pretty much always used Jack Palevich's Terminal Emulator app. Very small and lightweight. It's always done everything I've ever needed to do. But there are many Terminal apps to choose from. I usually stop trying apps, when I find one that meets my needs, and stick with it until it doesn't... I started using that Terminal my first week with my first Android, after trying a couple of others. I've never used anything since.
Hacker's keyboard is an awesome suggestion! Thanks man! How have I survived without this!
For VNC purposes (which I rarely use) I use androidVNC. I've never tried anything else since I use it so rarely. It seems to do everything I can imagine it should. Mostly I use it to mess with my wife's head with some "ghost in the shell" pranks when she is using her laptop. She will scream from the living room, "WTF!!!! My computer just told me it's going to eat my brains tonight!"
And I'm just innocently sitting there reading emails on my phone "That is strange, honey."

I actually looked at androidVNC first due to the amount of reviews and positive ones, but I liked the extra features of FreebVNC even though it violates my following policy. I have found, just like shopping at Amazon, that in general the quantity and quality of reviews quickly narrows the search dramatically from the huge database of products/apps. The only side effect of this is to weed out excellent apps that are new and could be excellent, but just like major operating system updates, with anything new I let them weed out the bugs first.

I totally agree with you that I don't ever see myself using the VNC client on the smartphone again other than just as a novelty. What does intrigue me is putting a VNC server on the smartphone. I wonder if there would be a way to use an external computer's mouse and keyboard to control the gui portion of the smartphone while displaying it on the computer's large screen, the problem being that the smartphone is touch based; that is something that I could see using.

Me and a friend used to do similar pranks at work, messing each others displays, keyboards, etc. I think the best non-computer prank that someone did to me while I was on vacation was to line one of my desk drawers with plastic and fill it full of goldfish. The best prank that some colleagues did, was to inflate a weather balloon in our departmental director's office and turn the nozzle away from the door so he couldn't get in.
Hello All,
Another ubuntu project here..
its a chroot jail free looped native framebuffered something?
one folder on sdcard called linux /sdcard/linux with the .img
your mount point..i use /data/local/mnt/linux
the scripts i use /data/local/mnt
simple you will need to edit the scripts if u edit ur paths..
ill share my stuffs if theres any interest in this.
dunno if this has been done on sgs2 using just scripts but yh
ive managed to get ubuntu13.04 running with full multitouch support using mtrack i use lxde/2d-unity
this approach uses android framebuffer instead of using a vncserver.
Concept/Goal: use android hardware to run linux without vnc and full hardware support...its christmas soon!
so we go a safe way and mount a img file and loop and chroot and mount necessary android stuff i.e /dev /proc /tmp-to help speed up system! and mount all sdcards.
then we kill android-the-framebuffer-hog
and start our xsession,
anyone interested in helping me?
i have the scripts and image, just need more nuerons!
to do is (alot)
Working:
Framebuffer >> full gamma and .mhz settings safe
Wifi
Bluetooth
Reboot to andoid and umount rootfs on log out
Mouse
Multitouch tap is click, double tap is ?grab window to move it, two fingers for right click, three to scroll
Screenshots
Charging
Sdcard
MicroSd
Keyboard >> virtual
Theres alot but its hard to summerise lol
Not Working (WIP)
get sound working completely (evrythings working except last output part) alsamixer, pulseaudio all work..just the last bit..so no sound.
figure out why system_bus_socket connection refused?
why dbus isnt being used but starting ok?
Landscape mode mouse axis. (i can rotate the display but the mouse axis are wrong.. up=right down=left) (portrait is fine)
camara
gpio-keys (hardware buttons)
calls
text messaging.
OTG USB (i made one so im assuming its that that doesnt work simply tweak to the xorg.conf to swap from touch to mouse..)
DRI & DRI2
GL_OES_EGL_image for 3d
have to use a virtual keyboard until running android apps in linux is figured out--ahem (i use matchbox-keyboard)
logon screen works but the keyboard is a issue. (virtual keyboard only starts once logged in. so no logon yet just auto logon)
you can still use ssh and vncserver if you wanted to..
any interest ill share my scripts...
as i said im not the only person to chroot imgs, but i havent seen a thread on getting it running natively on sgs2 without uboot or repartioning anything.
unless u completely recompile the linux os whilst inside of it, i.e adding vmlinux.img should be safe enough. works for me
anyway been a busy with this and im not a pro developer just a seasoned addict, thus the call for arms!
peace!
some screenshots
and you expect me to share my work when none of you have any input..phhhhhaaa
EDIT >> i was how you say suffering from a spot of pink eye! Strange strange thought patterns = WEIRD REMARKS lol

Interesting.
May I ask what are you using for? I mean, which killer app in Ubuntu you can't replace with an Android one?
Moreover, I have noticed an X server on the Play Store (https://play.google.com/store/apps/details?id=au.com.darkside.XServer)
Using it, instead of killing Android, may allow some more integration with the Android environment (e.g. you could still receive calls while using your ubuntu stuff).
Another improvement would be to use multiple consoles (you know, Ctrl-Alt-Fx stuff) to have both environments running
Just my 2ç

i mean to free up surfaceflinger and the framebuffer and send android into a slumber?so we can use it for our xsession. not KILL PERMANETLY
its like a chroot jail free no vnc something??
using vnc will allow u to still have android on in the background for calls and what not but thats chrooting a image to a mount point and running a app. awsome but i got bored with that..much perfere native input.
Search for linuxonandroid by zachthespack hes been dealing with chrooting linux for a long time and has a good application and a healthy stock of img files for you to use, plus a good how to. http://www.linuxonandroid.org Download from play store.. search 4 linuxonandroid
...thats not a bad idea zavorrax about the X11 app..
although running a third party app to use the framebuffer seems pointless when u can use the devices one!
wouldnt u rather have a true linux os in your pocket rather then a clever spin off of it, dont get me wrong i love android and its easy moddding.. linux is far better though.. this project im doing is after all, on a android device.
android root is always 0 ... root = / .... android apps are the users...if that makes sense?
linux uses users who log in..so root still has the initial setup of the os incase a user messes up, root can reset it with relative ease.
so in order to use linux for a vnc free linux, (root is in my opinion just like a programme.) needs to also be 0
thus, night night android..
its hard to explain, its linux and android?
basically the only way i can explain this is its the same as a chroot of a distro BUT instead of using vnc/X11 apks as the only way of having a GUI, we can optionally use the android framebuffer..fb0...
this thread wasnt ment to be a how-to just to see if theres any intrerest out here.
ill make a proper how to with all the basics needed.
as i said theres alot of these projects across the android platform, people trying too turn android back to linux/running linux.
u can pretty much use any img used for vnc or create your own for this.
theres a lot ubuntu/arch/debian/kali/backtrack..etc..etc
i initially add a file to my new img and apt-get a few things, run a few commands to change the img for my device then only need to execute my script,on the fly, hello linux desktop why not!
theres alot of debugging thats why im seeing if anyone is interested in this and would like to help/participate
i initially started using vnc years ago but got fed up with having to run a handful of scripts in this app and then find and add my ports and set passwords in another app, all using important cpu and power, so i thought why not make it all into one easy script.sh.......can of worms...
fruition was glimpsed so i continued.
just use it bcos i can
oh yeah and i say kill/sleep android, its all there..just not emulated/running a instance..sort of packed away in a box.(sleeping lol)
until i/someone can debug compatability for things like phone or proximity sensor then inside the linux GUI theres no support because it hasnt been setup/coded
thanks.

If you're not going to share your work, why are you posting about it on XDA?
Thread closed. OP if you decide to share this then contact me when you have links ready and I will reopen this thread.
So, I am at work and I showed off Linux on Dex to some other Developers and Engineers here.
Impressed they were, but it's time to really dig in.
Here is what I love about it on first look:
Great to have a fleshed Linux experience on my phone
Great dev tools come with the image (IntelliJ and also Visual Studio Code and more)
Has plenty of apps to get you started and it's pretty thoughtful
Looks great at 1920x1080 as well as 2560x1440 resolutions on a monitor
Switching between Dex and Ubuntu is pretty snappy
Things I didn't like:
Just a LITTLE bit laggy sometimes
Need to either use ARM compiled apps or compile them yourself
The Default 10GB partition size was too small, so I would suggest using 15GB at least, after updates/upgrades (Ubuntu OS updates that is), you'll still have about 35% free space with 15GB disk
You cannot "install" this on the SDCard, only internal memory, so keep that in mind if you have the 128GB model and tons of apps
Once installed, you cannot delete the 3GB+ zip file you downloaded, so there is that wasted space as well (ok, I have not tried REALLY hard to delete it yet, but Google Files won't delete it, nor do I know the repercussions of deleting this file too)
I'm still trying to work out how to access the files on the device (outside the Linux container), not sure if it is possible, but I have not had a lot of time with it as of now
BONUS!!
When you are not in Dex mode (normal handset mode), you can still launch Linux on Dex, but you cannot get the full desktop experience.
Click on the Terminal icon under the RUN button and you can drop into the Ubuntu Shell and still use commands (like SSH-ing to servers using your certs and stuff).
Of course, the down side, small screen. Hey, in a pinch, when I am on the road and needs to SSH into an AWS instance and run a couple commands, I won't complain!!
All in all, I think this will be great for Dev's to play with, not sure how useful it REALLY will be, but I know from a DevOps/Architect/Engineer, it's nice to have as a backup to be able to actually take care of things without having to drag out the whole laptop.
All this, with a $20 adapter.
Any other thoughts for those that have used it?
Hello friend, I have mine installed on my 128gb Sdcard.
How did you get it on your SD Card?
Thanks!

Move the file from LoD folder to the SD card and reassign the file location in the Linux on Dex app, it worked for me but moved it back to internal storage to ensure best performance .
My impression? They will poorly maintain it and I suspect it will be discontinued without any real notice. Registration was broken for well over a week before signups ended. You cannot get in contact with anyone from the team. Care doesn't even know it exists.
I am yet to find a use case that improves upon remote access to an Ubuntu 18.04 VM running on a cloud or at home, but I'm not a developer.
Perhaps if you are stuck somewhere without an Internet connection and feel like coding somewhere in the mountains or in the jungle.. But then you would need a handy monitor, keyboard, mouse and a power source..?
I think I can sum this up in one simple sentence - "Because I can..."
It's like having linux on a PS3, because it could.
Haven't had a chance to use it yet but looks promising. That doesn't mean it will be supported very well, time will tell.
Hardware wise it should work very well, and there is ALWAYS a good reason to have a handy (mostly) self-contained PC with you in case you CAN'T access the net...
Would be great to get an idea of some real life use cases..
Would be very happy to see this project pick up some community developer attention, the platform is only as good as the tools developed for it.
In the absence of an official LoD forum for developers perhaps that community should be developed here.

I got this installed on my 8GB Note 9 today. I didn't get registered for the beta, but download the app and the Ubuntu image and got it all up and running today. My only complaint so far is it won't run full screen on Dex. That may be because I'm running the Pie Beta. Not sure how it operates on Oreo Dex.
I'll play around with it more later. I basically just plugged into my monitor and opened it up today.
Well, here is a real-life use case that saved me a TON of time and effort.
I set up the Linux on Dex with many tools and configs I need to be able to do my work (Sr. DevOps Architect/Engineer) on my AWS servers. I had an instance that was having some issues and was notified via the monitoring platform and was able to get my phone out, run the Ubuntu Shell and SSH/Fix the issue without ever having to pull out the laptop and tether it while on the train headed home.
There ARE some use cases where this will come in handy, but I do agree that these are real "edge" cases too. No "normal" user will ever really find this helpful.

Full screen on oreo.. Have you tried Dex max app?
planning to install LoD and curious if it can actually decompile and recompile apk's as a laptop would..?! mostly I'm interested in Themes for Samsung.. using few apk as templates to swap files, images and recompiling the apk, will it be able and will it properly sign it ?! and if so which way should I go?! do I need to install java, SDK, plugin I saw there ?!
any advice would be great.. thanx..
