[?] Libs in /system/lib - Sony Cross-Device General

Is it possible to find which app uses which libraries? For example I would like to know which libs are used by the Camera application in order to port it or to completely remove any dependencies from the system. Thank you!

Normally, you use the ldd command http://linux.die.net/man/1/ldd for this.
Another one would be
readelf -d executable | grep NEEDED
Unfortunately, these are missing on android, if I am correct.
Best way would be to look on the build-machine I guess, using a full set of Linux and cross-compiler-tools.

[TUT]-PORTING-Android To The VOGUE

the title says it
after many requests here is the guide
most of this is spread around the vogue
forum here and there, i just wanted to bring it all together
goal-seeing lately we have lost some good developers, this is a shot at getting more involvement in vogue/android development
I.SETTING UP YOUR SYSTEM
1. GETTING LINUX you will need to have Linux installed on your computer(dual-boot, vm, whatever). i recommend Ubuntu karmic (9.10) because its pretty new-user friendly. It can be found at http://www.ubuntu.com/
for you windows lovers here is a guide to setting up a ubuntu VM(virtual machine (if you really didnt know ))
2. THINGS/TOOLS YOU WILL NEED download these:
original 8/8/09 ion 1.5 build HERE(we are gonna use the bin-files and the apns-conf.xml, and a few apps)
the latest rootfs.img (find it)
these android tools (included are genext2fs (android version), split_bootimg.pl, and extract_ramdisk.sh)
after downloading, extract the zip to a folder. open a terminal and cd to the dir of the tools. click applications>accesories>terminal and type:
Code:
cd ~/whatever/
sudo rm -rf /bin/genext2fs
#dont type whats after the pound signs
#type in your password
#if you havent set up a su password yet type:
sudo passwd
#then make one, next
sudo cp -r ./whatever/genext2fs /bin/
squashfs-tools (if you have ubuntu 9.10-karmic first you will have to uninstall squashfs-tools 4.0(4.0 WILL NOT NOT NOT NOT NOT WORK) that is installed during the installation of linux ): go to system>administration>synaptic package manager. type squashfs-tools in the quick search, then right click and click mark for complete removal. then hit apply. then download and install this here http://http://ftp.us.debian.org/debian/pool/main/s/squashfs/squashfs-tools_3.3-7_i386.deb
i also strongly recommend downloading the sdk-tools v1.1(adb is almost essential when porting, for debugging purposes) enatefox has it posted on his media fire. (search for it)
3. ORGANIZATION
now that we have what we need. lets get organized.
a.mount points
we are going to use mount points while porting.
terminal:
Code:
sudo mkdir /mnt/rootfs
sudo mkdir /mnt/system
#i also have one for mounting data files
mkdir /mnt/data
b. directories
terminal:
Code:
mkdir ~/Desktop/android
mkdir ~/Desktop/android/ion
mkdir ~/Desktop/android/donut
#you get the point...
now put the ion 8/8/09 build in the ~/Desktop/android/ion folder and rename it system.sqsh then
terminal:
Code:
cd ~/Desktop/android/ion
unsquashfs ./system.sqsh
you should now have a folder called squashfs-root in the ion directory. it contains all the guts from the ion build. feel free to look around in that folder as you should get familiar with the folders and things in there
II PORTING
1. PORTING A HERO ROM(this was in zens how-to-make-a-hero-rom.txt im just adding on to it)
a. Download a rom from the dream/sapphire development forums.
b. Extract what you downloaded to ~/Desktop/android/hero. It is usually an update.zip.
c. Open the extracted folder. Inside you should see a data directory and a system directory.
d. Open the data directory and look for an app or app_s folder.
e. Open those folders and copy the apks to the system/app/ folder. Leave out what you don't need. feel free to add any custom apps. as long as they are from the same sdk number. ie 1.5, 1.6, 2.0.1, 2.1 most are pretty cross-compatible though.
f. Delete system/xbin from the rom your porting and replace it with the one from Ion.
g. Copy ~/Desktop/android/ion/squashfs-root/etc/apns-conf.xml from Ion to ~/Desktop/android/hero/system/etc/
h. Mount the latest rootfs.img
terminal:
Code:
sudo mount ~/whereever/rootfs.img -o loop /mnt/rootfs
i. Copy libaudio.so libaudioflinger.so libcameraservice.so libgps.so from /lib in the mounted rootfs over to system/lib in the rom you are porting*(donut and eclair really dont need this step because those files are in most of the latest rootfs.img's but be sure to check)
j. Edit the system/build.prop or even use the Ion build.prop.*(for donut/eclair you may want to edit the lcd density to 120 or 110 in the build.prop for qvga and 160 for 320x480)
k. Create a blank file in system/ called hero.build*(for eclair/donut create donut.build or eclair.build or eclairhero.build.....etc)
*l. for hero any systems too big to run on nand, here is a script to make a data file. put this in the ~/Desktop/android/hero directory. cut the app folder from ~/Desktop/android/hero/system and paste it to ~/Desktop/android/hero , and rename it too app_s . next run the mkdataimg.sh it should ask for you password in a terminal. type it in and then it should mount the data.img to data-mnt folder in ~/Desktop/android/hero . keep that terminal open copy the app_s folder in to data-mnt. then type y in the terminal to unmount the data.img. next:
terminal:
Code:
cd ~/Desktop/android/hero
ln -s /data/app_s ./system/app
that should make a broken symlink in system
2. Mount it and squash it
ok now that we are done porting lets put it together
terminal:
Code:
cd ~/Desktop/android/hero
genext2fs -d ./system -b 180000 -a system.ext2
sudo mount -o loop ./system.ext2 /mnt/system
sudo mksquashfs /mnt/system system.sqsh
sudo chown $USER ./system.sqsh
#and if you want
rm -rf ./system.ext2
from zenulator:
There are other little tweaks here and there but thats basically it. Now you can roll your own.

im gonna clean this up a bit later just wanted to get this out to you guys
nice thanks jamezelle
zen's manup456-based Eclair build contains different libaudio.so & libaudioflinger.so than the rootfs, and Eclair wouldn't boot if I replaced them with the libs from the rootfs. This might be due to the rootfs libs not being updated for Eclair yet (also why voice search/dial doesn't work) but I'm not sure. I don't know if this will be the case for 2.1, just wanted to add that in.
I really appreciate the guide and look forward to hearing more. I've learned a lot from zen as well but a lot of the work the devs do is so hard to follow because it's undocumented.
Do you know why the xbin has to be from Ion? Is it because of our kernel version or the squashfs ver that our kernel contains? I've been wanting to grab some of the tools from the xbin of other builds but have been unsure about compatibility.
Also, for more advanced Android ROM building, I'd like to add a link to zipalign optimization.

we need to move back to a more standardized comunity rootfs.img. i'm seeing more and more different rootfs.imgs that vary little by little. it is kind of hard to really document all of the development. but i see your point. the xbin(are just eXtended bin files) doesnt have to come from ion. the xbin in ion is actually empty
yes our kernel doesnt support LZMA compression which is what 4.0 uses. more info on it here http://www.squashfs-lzma.org/ i dont know why out kernel has not been updated to support it(you would have to ask DZO), i just know is isnt supported
thanks for the link to zipalign. i usually zipalign my apps. btw most dream and sapphire devs are already zipaligning there apks so we dont have to
I agree, I don't like forking the rootfs but the latest ones don't contain the correct WiFi files & settings for Kaiser. I know our kernel is way behind, I've asked several questions in the kernel thread about it but then the thread goes OT and I've never gotten an answer to most of the questions. Newbie16 has been compiling kernels but we've had trouble finding all the updated source files.
Oh, the PNG optimization in the zipalign thread is useful also, I easily saved 5 MB in the Eclair build.
The 8/8 file is a .img file, not .sqsh. Terminal tells me it can't find a sqash superblock on the file, or something to that extent.
EDIT: also missing a step that seems crucial... re squashing the files to make a .sqsh file to use?
ln -s help. hero nand porting
When ever I'm trying to port a hero build to nand ln -s gives me "operation not permitted" during boot. I used -a during genext2fs. Also data didn't work, even though I have the right apns-conif.xml. any idea? I was trying to port hero revolution (I think thats it ). Thanx

Could someone please define rootfs, zIMage and the other parts that go into an Android build? If you're going from say, donut, to eclair, which ones can you reuse? I think I understand that the system.sqsh is what makes a build donut or eclair and actually is the file that has the customizations in it. But, what do the other parts do? If this is the wrong place to post this, mods, please move this. Thanks.

Hey guys, don't know if anyone else is having this issue or not.
I'm trying to work with the Topaz kernals...I downloaded the XDAndroid 2.1 system.sqsh and was able to unsquashfs it fine on my Vector Linux box...but I want to do the same to the TopazKernal16 system.sqsh (donut) but when I run unsquashfs it makes it to about 70% (highest I got to was 80% on one try) and then stops saying "killed".
any way to remedy this? also, what is the simplest way to "re"squash it?
Thanks!

I would be interested in the Android's filesystem breakdown. Just some guide on what exactly is in the system, and then rootfs.img and then the modules. If someone could point me in the right direction, that would be much appreciated!

[TOOL] MTD-Utils for Android (incl. nanddump/nandwrite)

I could not find any binaries of the MTD-Utils (a set of useful tools when dealing with flash devices; see http://www.linux-mtd.infradead.org/index.html) for Android so I compiled some Android binaries from the source (http://git.infradead.org/mtd-utils.git).
My main interest was to get the two programs 'nanddump' and 'nandwrite' running on Android which must be used instead of 'dd' when creating images of nand partitions and restoring partitions from these images, because dd does not handle the bad blocks on the nand correctly which could lead to corrupted data.
With these two tools more flexible backup/recovery tools can be implemented since a backup/recovery can be made for every partition available on the device, even those which do not have a readable filesystem, for example the bootloader. Also, for partitions which include a filesystem, but hide some extra data outside that filesystem, this hidden data will also be included in the backup. These raw nand partition images can be tar'd or zip'd to reduce the size of the backup files.

Dump from one device wont work on other, if they are very similar it has few chances of booting but else it'ld brick if you dont be safe!
Actually, I want to remove some system app and then install other app, and make all configuration. After that, I want to clone this configuration to other mobile device with same model. Do you have any suggestions ?
Thanks.

Ok so you got a phone (model a) and you wanna remove sumtin frm /system/app n add sumtin back n then let some user having the same model a use it
Get root
Install root explorer or any root file explorer
Allow su permissions
Navigate to /system/app and do what you wanted
Then you can dump the /system partition
Kindly give some more info of your device - will help more
And yes also paste the output of "mount" command
I think I can only give more information about the phone after I back to my office.
Actually, I am using System App Remover to remove the System App. It does the job.
Wow can I dump and restore the system partition ? I have tried to use dd command, but it fails. May be nanddump will help, but I cannot find the documentation how to use it. Please help. Thanks.
Is there any way to have nanddump directly send the image to a PC that is running recv_image? I'd like to use nanddump on my Galaxy Nexus, but since it is lacking an SD card, it would seem like writing the nanddump image to the nand would just destroy any possibility of obtaining a clean nand image.
I found a way using netcat...
From host machine in one console window:
Code:
adb.exe forward tcp:5555 tcp:5555
adb.exe shell
# nanddump [options] /dev/mtd/mtd0 | nc -l -p 5555
From host machine in a second console window
Code:
nc 127.0.0.1 5555 > flashdump.bin
So how does nanddump compare with Nandroid, which uses mkyaffs2image to create .img files?
So does n e one a mirror for this??? Multiupload is no good n e more...

mtd ultil for android
ok guys...
1st: sorry for reviving this topic ...
2nd:here ara the binaries for android: http://goo.gl/eJ8mX
3rd and most importanto to me:
If I do a nandread mtd7 > mtd7.img (in my case the /misc partition) I can do a nandwrite mtd7.img > /dev/mtd/mtd7 without any data corruption ?
I have a lot of backups of many partition except this /misc that in freaking me!
So. Is this a reliablbe backup/restore system ? can I do it with all mtd partition ?
* I tested nandread in qcom msm_7x27 device running android 2.3.6.

[UPDATE 2/12/2010] Terminal IDE - Full 'on device' Java / Android IDE

[UPDATE]
BusyBox 1.19.2
Bash 4.2
Midnight Commander 4.8
TMUX 1.5 - That's right, full terminal multiplexer..
Vim 7.3
Terminal IDE ASCII Soft keyboard first round bug fixes complete.
It's the addition of TMUX and MC that really excites..
--------------------------
Well,
As the only people I know who might even be interested in this, I would like to announce the release of Terminal IDE v1.0.
A complete Java / Android Development Environment that runs on the device itself, with a nice telnetd / sshd feature.
For Android. Of course... Eat this you IPhone Hounds..
Woo HOO!!
The application is available on Android Market.
https://market.android.com/details?id=com.spartacusrex.spartacuside
As what I can only describe as 'dark days' finally draw to an end, I am very pleased with this first draft.
PLEASE give it a go, log in over telnet for a smoother ride, and let me know how it goes..
DO THE TUTORIAL! Does it work ?!
I have released the whole project GPLv2! Yeah, Who Knew!?
http://code.google.com/p/terminal-ide/
BOOOOOM!
Spartacus
a link to the app in the market would be usefull.
Interesting. Was just wondering about coding on my tablet.
Pretty freakin sweet
Thanks for putting this out!
Awesome
The full keyboard alone makes it worth downloading, but the IDE as well - wow!
this is best bro.
I randomly found this last night while looking for a decent mobile IDE for my tablet. I was looking for a simple text editor with syntax highlighting and you've taken that extra step to include other tools for ssh, telnet and compilers. Much appreciated.
One question, how do you start the ssh server? sshd doesn't seem to do it. I would like to scp files to my device from my desktop in order to work on my commute.
Thanks
The sshd app is actually called Dropbear.
You also have Dropbearkey.
You use Dropbearkey to generate the sshd certificates you need.
I really need to add a tutorial on setting the sshd keys up
For now Google has a couple of articles on it.
For file transfers you also have busybox FTP but I admit not terribley secure..
Allthough SSH is provided, and I wonder whether an SSH pipe can be created..?
And lastly you can just copy the files over to your sdcard via USB..
Will look into it & add tutorials asap.
Ok. So I now have SSHD working..
But there is a slight issue.. basically when you log in you have to start bash manually.. unless you have the file /etc/shell with the correct shell to use.. Which requires a rooted phone.
Since Terminal IDE is for non-ROOT users, I will have to recompile the code to allow a shell to be specified on the command line.. Soon..
FOR NOW - This is how to connect to the phone via SSH (There are other ways using public keys but this is one way)
So - Once in Terminal IDE
2) You need to create a couple of server ssh keys
Start in $HOME
Code:
cd ~
Create folder
Code:
mkdir .ssh
Give it some secure permissions
Code:
chmod 700 .ssh
Get in there
Code:
cd .ssh
Now create the keys
Code:
dropbearkey -t dss -f dropbear_dss_host_key
dropbearkey -t rsa -f dropbear_rsa_host_key
ok - That's almost it. Just need to start dropbear with the correct parameters now. [Probably want to keep this in a script]
Back HOME
Code:
cd ~
You need to know the UID of your app, which is different per phone - use 'id'
Code:
id
That will tell you your user ID / Group ID. Let's say its 10058.
Now to start DropBear
Code:
dropbear -A -N username -U 10058 -G 10058 -C password -d ~/.ssh/dropbear_dss_host_key -r ~/.ssh/dropbear_rsa_host_key -F -E -p 8090 -P PidFile
This will start it running in the foreground with password set to 'password' on port 8090.
Then you can connect, like telnet, and simply use 'password' for the password.
Now for the issue. It will start a simple shell session in / with no ENVIRONMENT variables or anything..
I'll fix it permanently in a future release, but for now it can be fixed with these 2 commands.
cd into your home dir - Check this is correct on your device
Code:
cd /data/data/com.spartacusrex.spartacuside/files
And start bash with an init file Terminal IDE auto-magically creates..
Code:
./system/bin/bash --init-file ./.init
Everything should now be setup as usual.
Good luck..
Very awesome and thank you sir. Works like a charm.
One thing to clarify for those "braving" this (not that it's all that insane to try)... the '-N' is setting the username (in the case of the example, setting it to 'username').
Also, it gives a permission denied for scp, I'm assuming since it doesn't init/run the shell. Should be fine since FTP is included. Haven't tried this option yet. Not too worried about security at the moment, since I'll only run it on a private network.
May I make a (maybe) small feature request? Is it possible to include a "keep screen awake" option in the options menu? I have my Xoom config'd to turn off the wifi when the screen is off for power saving (can go ~4 days on 1 charge), so it will kill my connections if I let this happen. I know not everyone has this config set, but it'd be a nice option.
NOW, if I wasn't lazy, I could probably add this myself and build since I've dl'd the source. But, lazy and working on a few projects already.
Again, much thanks.
And as if by magic..
Funnily enough I was having the exact same issue last night while using wget to transfer a big file to my device..
NEW VERSION UPLOADED v1.13
Now has 3 non-exclusive lock types available in the options :
- CPU Lock
- SCREEN Lock
- WIFI Lock
Set them as you wish...
Saw that this morning when I was on the bus (Thursday morning here in Hong Kong). Very awesome and much appreciated.
As well, thanks for open-sourcing it. +1 for you sir!
Very cool stuff
Thanks for creating this.
Great app! However I can't compile .java files. I always get an error that it can't unzip a file in /android.policy.jar. Any idea?

Most likely seems to be due to the ROM you are using and/or the market version
can u post the build.prop here?
/system/build.prop
also, try going back to market 2.x, 3.x market(s) do loads of checks
Does anybody know why I can't compile java files? I always get the following error:
Error reading /system/framework/android_policy.jar cannot read zip file.
Any ideas? Could anyone upload there android_policy.jar because that might cause the error.

Hi Schindler33.
Can I ask, have you followed the tutorials, say the first helloworld example TO THE LETTER?
Does the helloworld example work?
The parameters have to be correct, and as always exact, and the BOOTCLASSPATH variable must be set.
If so, is it a custom ROM?
Does that policy jar file exist and is it readable by non root users?
As much info as possible good..

[Q] Hopefully simple Nook Touch question...

I have a Nook Simple Touch, BNRV300, and I have successfully modified uRamdisk to gain root shell access with ADB over USB (Thanks Renate!). I am currently on firmware version 1.2.1.
I know this may seem like heresy to some here, but I really do not want or need to root my NST and add a number of apps I won't use anyway. I have a fully rooted Nexus 7 for that sort of thing.
All I would like to be able to do is turn off the need to swipe to unlock when returning from sleep, and modify the text on the screensaver overlay.
I have discovered, by the way, that sqlite3 does not seem to be available on this NST, as when trying to use it via ADB shell, it says "sqlite3: not found".
SO, there we are... I would greatly appreciate any assistance offered.
MildBill
P.S. I have tried Nook Manager, and while it did what I wanted, there were many things added that I just have no need for. And, battery drain seemed to double.So, it had to go.
Regarding SQLite3.
Since the guts of it (libsqlite.so) is already in the Nook, you only need the command line executable (sqlite3).
It's here: http://forum.xda-developers.com/showthread.php?p=50958855#post50958855
Unzip it, stick it in /system/bin, chmod 755 it.

Ahh, once again, thank you Renate. Now if I can get some idea on my main questions...
There are no simple questions here. Even the answers are complicated.
Many people have created solutions and packed them into these "manager" things.
I finally got around to doing my own minimal one.
It's packaged up in nook121patch.zip (in the signature).
Code:
C:\>adb pull /system/framework/android.policy.jar
C:\>apktool d android.policy.jar \AP
C:\>mergesmali /v C:\AP\smali C:\Nook121Patch\KeyguardViewMediator.smali
C:\>apktool b C:\AP android.policy.jar
C:\>adb shell stop
C:\>adb mount -o rw,remount /dev/block/mmcblk0p5 /system
C:\>adb push android.policy.jar /system/framework/
C:\>adb shell chmod 644 /system/framework/android.policy.jar
C:\>adb shell reboot

Well Renate, I hate to complicate your answer any more than necessary, but...
On the Temblast page that clicking on your signature takes me to, I do see mergesmali, one of the two tools I will need based on the instructions you gave. I do not see nook121patch.zip, nor apktool, however. Where can I find these?
Also, can you tell me something about what this will do for me?
I hate to be such a noob, I have just enough knowledge to be dangerous. Thanks again for all your help, sorry I have to keep asking for more.
MildBill
Well, I wasn't that clear.
mergesmali is in the signature, nook121patch.zip is on the mergesmali project page too.
Apktool is detailed and linked here: http://forum.xda-developers.com/wiki/Apktool
There are many patches in the nook121patch.zip
You can apply them selectively.
.jar is easy, they don't need signing.
.apk is trickier they must be signed.
System .apk is even trickier, they must be signed with the system signature.
The KeyguardViewMediator.smali will make that your Nook just opens with a push of the power button and no swipe.

OK so far, and (I think) I have apktool properly installed, then realized I also needed to install the Java Development Kit as well to use it, which I managed to do. But, when I try to do
Code:
C:\>apktool d android.policy.jar \AP
I get
Code:
Input file (\AP) was not found or was not readable.
as a response.
So, I guess I need to return to the magic well of your knowledge for further assistance and/or instruction.
To which I can only add...
HELP!
EDIT: By the way, I am using an adb.exe implementation from another root kit I have installed, not the standard installation from the SDK. Is this perhaps part of my problem?
Well, something goofy is going on there.
Type just apktool and get the usage and version.
\AP in this case is the destination directory.
It should not already exist or else you get a warning.
Maybe the input file (the jar) can't be found, but the error message is wrong?
Code:
C:\>apktool

Well, there ya go... I got apktool v2.0.0b9.
I can get 1.5.2, but will it work with Java 7? Oh well, live and learn I guess...
MildBill
Oh, well, then the 2.0 probably uses different args.
"apktool" by itself will tell you the order of arguments.
To run anything on the desktop the Java 7 runtime environment is fine.
To compile an Android application you have to use Java 6.0 SDK.

Well then, since it appears from the changes that 2.0 requires the Java 7 SDK, I guess I'll uninstall it all and get 1.5.2 and Java 6.
I'm running desktop applications:
Code:
C:\>java.exe -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode, sharing)
I'm compiling Android applications with:
Code:
C:\>javac.exe -version
javac 1.6.0_38-ea
apktool runs under the JRE, version 1.7 is fine.
OK, finally got around to completing the instructions as posted, and except for having to add the command 'shell' to the mount statement, everything worked fine. And, it accomplishes exactly what I was after.
Next I may look into trying your library and reader apps.
Thanks again!
MildBill
P.S. You might consider rewriting the readme file included in nook121patch.zip to better describe what each patch does.
The readme is admittedly very old.
That's because I forgot that it's even there!
Each of the individual smali files has comments at the head saying what it does.
I'll make something to compile the individual comments into a single readme.
I can also report, at this point, that unlike an other method I have tried to accomplish this simple task, this one does NOT run thru battery life like it was going out of style.
The next most popular option, NookManager, which uses the NookModManager to do this fix, uses an average of 10% battery life every day, even when in in sleep mode the whole time. Turning the option off (I.E. reinstating the swipe to unlock) again reduces battery drain to a more normal point.
But, the fix by Renate seems to use nomorebattery than the stock reader, whether reading, sleeping, with WiFi on or off. I like it!
Once again, Renate, thank you very much for this, and for all you have done for the Nook community.

[GUIDE] How to make GSIs overlay file for your phone

Hello, when you using phh's GSIs, you may found bugs on auto brightness, battery usage data, etc (e.g: Xiaomi, Huawei, etc.). For this, you can make an overlay files for your mobiles.
Requirements:
framework-res.apk on your stock rom. (It may on /system/framework/framework-res.apk)
apktool (to extract framework-res.apk)
git (to clone repo)
Linux (to build overlay files)
Steps:
1. Fork phhusson/vendor_hardware_overlay on GitHub.
2. Clone Repository which you forked, and make a new branch for your works.
3. Copy a device which similar for your device, and rename it to your own device.
4. Edit <Your device>/Android.mk (Just modify the contents of the brackets, same as below)
Code:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_PACKAGE_NAME := treble-overlay-[Manufacturer of your device]-[Name of your device]
LOCAL_MODULE_PATH := $(TARGET_OUT)/overlay
LOCAL_IS_RUNTIME_RESOURCE_OVERLAY := true
LOCAL_PRIVATE_PLATFORM_APIS := true
include $(BUILD_PACKAGE)
5. Edit <Your device>/AndroidManifest.xml
Code:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.phh.treble.overlay.[Manufacturer of your device].[Name of your device]"
android:versionCode="1"
android:versionName="1.0">
<overlay android:targetPackage="android"
android:requiredSystemPropertyName="ro.vendor.build.fingerprint"
android:requiredSystemPropertyValue="+[write as similar format]*"
android:priority="[Take next number of last used]"
android:isStatic="true" />
</manifest>
If you don't know how to take androidriority, you can execute this commands to list priority which used already:
Code:
cd [Path of repository]
find -name AndroidManifest.xml |while read manifest;do packagename="$(xmlstarlet sel -t -m '//manifest' -v @package -n $manifest)";priority="$(xmlstarlet sel -t -m '//overlay' -v @android:priority -n $manifest)";echo -e "$priority\t$packagename";done|more
(the single line command split here, just for viewing or making a shell script):
Code:
find -name AndroidManifest.xml |while read manifest;do
packagename="$(xmlstarlet sel -t -m '//manifest' -v @package -n $manifest)";
priority="$(xmlstarlet sel -t -m '//overlay' -v @android:priority -n $manifest)";
echo -e "$priority\t$packagename";
done
It will print a list for you (unsorted), and you just take an unused priority.
You can find device fingerprint on /vendor/build.prop, or execute following commands (on your device or adb shell):
Code:
getprop ro.vendor.build.fingerprint
If you can't find ro.vendor.build.fingerprint, you can find ro.vendor.product.name or ro.product.vendor.device, then change android:requiredSystemPropertyName and android:requiredSystemPropertyValue what you found.
Huawei seems to use ro.hw.oemName to detect phone, and others manufacturer maybe have their own detection, too. But it should be unique for other phones with same manufacturer.
(It's NOT recommended unless your device don't have ro.vendor.build.fingerprint.)
6. Extract framework-res.apk with apktool on another side. (to avoid commited by mistake)
7. Replace <Your device>/res/xml/power_profile.xml to which power_profile.xml for your device.
It will on <Extracted framework-res.apk>/res/xml/power_profile.xml.
Or you can find whoever's device tree, it may have this file, too.
8. Edit <Your device>/res/values/config.xml
Find each key on following files what for your device:
Code:
[Extracted framework-res.apk]/res/values/arrays.xml
[Extracted framework-res.apk]/res/values/bools.xml
[Extracted framework-res.apk]/res/values/fractions.xml
[Extracted framework-res.apk]/res/values/integers.xml
And then replace values into <Your device>/res/values/config.xml
9. Add your device into <Path of repository>/overlay.mk
Just write like other lines.
10. Build overlays
Just execute following commands:
Code:
chmod u+x [Path of repository]/build/build.sh
[Path of repository]/build/build.sh
If You get this, Do what it said:
Code:
Please install aapt (apt install aapt should do)
Or if you get this:
Code:
OpenJDK Server VM warning: You have loaded library /root/overlay/vendor_hardware_overlay/build/signapk/libconscrypt_openjdk_jni.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.conscrypt.NativeCrypto.get_cipher_names(Ljava/lang/String;)[Ljava/lang/String;
at org.conscrypt.NativeCrypto.get_cipher_names(Native Method)
at org.conscrypt.NativeCrypto.<clinit>(NativeCrypto.java:764)
at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:56)
at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:49)
at com.android.signapk.SignApk.main(SignApk.java:942)
I have no solution, either. Try to build on another computer.
11. Test overlay with tests.sh and yourself
For general checks (symtax, etc.), just execute following command:
Code:
chmod u+x [Path of repository]/tests/tests.sh
[Path of repository]/tests/tests.sh
You should fix errors what reported for your device, and then restart from step 10.
If it reported errors but not for your device, just ignore it.
When check passed, you can find overlay file on <Path of repository>/build/treble-overlay-<Manufacturer of your device>-<Name of your device>.apk, just copy it into your phone's /system/overlay/, and set permission to rw-r--r-- / 0644.
And then reboot your phone to test your overlay.
12. If it works for your device, don't forget to perform a pull request for phhusson/vendor_hardware_overlay, to support his awesome works.
Thanks for the guide @minadzuki
but i'm getting this error after step 10:

Oh...I forgot this, sorry.
Because I haven't encountered this error, so I don't have a way to solve it, either. (I tried to built it on three remote servers only)
And...is it cause segment fault?
Or you can try to install google-android-build-tools instead of aapt. (because I can't find aapt on archlinux but found this)
Very nice guide, thanks!
I'll link it as part of a "how to contribute"
For aapt, there is an aapt included in the git. If it doesn't work for you (like @king1990's segfault), know that the one included in the git has the lowest priority. It will pick up aapt from the system first.
(but then you'll need to have a system-wide aapt).
Or if you have an Android SDK somewhere, you can set your PATH to include it.
Edit: I just realized that what I just described might actually be the issue. If there is a system-wide aapt, it will use the libc++ in the git, which would explain the crash.
I fixed this case in my current git.
If there is a system-wide aapt it will use it.
If for some reason, system-wide aapt isn't suitable, you can run build.sh with --local-aapt to force the use of the in-git aapt (i.e. it will have higher priority than system's so no conflict should happen)

Could you check again with latest git?
If it still doesn't work, can you try to call build.sh --local-aapt ?
@phhusson Thanks now it working fine and building without faults
I have few questions regarding the AndroidManifest.xml :
1- for android:requiredSystemPropertyValue how do I know which name to use ? is it trial and error ?
2- for androidriority does matter which number I choose ?
3- some vendors have this overlay (framework-res__auto_generated_rro.apk) under "vendor/overlay". Does is affect the device overlay in system/overlay ?
4- to install the overlay is it just as @minadzuki says ?
and thanks again for your great work

1. For example, Xiaomi Mi 6X has this fingerprint:
xiaomi/wayne/wayne:8.1.0/OPM1.171019.011/8.7.12:user/release-keys/
So you can take xiaomi/wayne to use, and android:requiredSystemPropertyValue will be: +xiaomi/wayne*
2. it will affect to build images, or affect the detection on System. If you got this:
Code:
F: .xxx/AndroidManifest.xml: priority xx conflicts with another manifest
You just take next number and try again, until now priority 53 has been taken (without pull request), you can take priority since 54.
3. Sorry, I don't know for this.
4. Yes, just simply copy and permission change.

overlays in /system/overlay and /vendor/overlay are the same thing, and on my GSI both are loaded, so yes it affects it.
But if your vendor has a framework-res__auto_generated_rro.apk, you probably don't need an overlay file for your phone, because it's already there.
(Please note that /system/overlay doesn't exist in AOSP, that's a change specific to my ROM, and custom ROMs based on it. AOSP only has /vendor/overlay)
@minadzuki Thanks for answering my questions. @phhusson its clear now , I don't know if this is related to your treble approach or not but some GSI ROMs refuse to go the minimum value in the brightness curve no mater what value I set in the curve, it never achieved.
is this treble or ROM related ?

Brightness is a bit complex on Android Pie... (well it already was before, but it got even worse)
Do you have a link to your current overlay, so I can take a look at which code path you'd go to?
What's the lowest backlight value you get in /sys/class/backlight/panel0-backlight/brightness or /sys/class/leds/lcd-backlight/brightness?
Also what's your device? Does it have extended brightness range? (what's the value of getprop persist.sys.qcom-brightness // is it a samsung device?)

for overlay this the extracted files from the overlay apk (my device is Axon7)
The lowest backlight is 10 (once manually edit it to 1 it goes to really dim brightness)
what I don't understand that I already built two GSI ROMs one is DU13 & other Liquid pie both report the same backlight light value at 10 at minimum value but in DU its very dim and in liquid its still bright ?!
The command did not give back any information so I assume we don't extended brightness range.
Thanks
Edit : it was overlay problem , fixed after modifying it
I tried to create an overlay for my Honor View 10 (Berkeley)
Is there a list of recommended settings to copy over from the stock ROM? I started with copying everything listed in tests/knownKeys and it seems to work
There's a power_profile.xml in the framework-res.apk I dumped from my stock ROM but the battery capacity is set to 1000 instead of 3750. Is that right?
There's also a power_profile_test.xml in there with a much more sane value of 3000 mAh. Should I use this one instead?

On Huawei, you'll find real power_profile.xml somewhere in /odm or /product. I'd say /product/etc/power_profile.xml

Yes, you can write source code everywhere (don't forget to replace CRLF to LF), but maybe you should build it on Linux, or you have a way to build it on Windows (e.g.: WSL, Mingw, etc.)
@minadzuki I can't find a config.xml in my framework-res.apk, am I missing something? or that gets created somehow in the process?
another question
on step 5 you say to edit AndroidManifext.xml, does that means delete everything in it and copy paste what you put on the code box? or just add that at the end of the xml file?

framework-res.apk doesn't contain config.xml, it split into several files: arrays.xml, bools.xml, fraction.xml, integers.xml. just create config.xml or copy from other devices and find values on these files (to replace it).
and step 5, just replace values which for your device, like what other devices wrote.

thanks for the response but I am really lost here those 4 xml has way to much data in it, should I just copy everything to config.xml?
to be honest what I am trying to fix are 2 things the battery stats not showing and the auto brightness and brightness slider and if the led light is fixable by an overlay that too, I can provide you all the files needed could you build it for me please? my device is an HTC U12+

you can check like this:

then take values from those 4 xmls.
