App install Fails?

hey all iv noticed this a lot with the stock 2.2 rom on my POV Mobii tegra 2 (advent vega rebrand).
e.g i uninstalled a game called jelly defence, then tried to install an updated version of it. the install fails saying aplication not installed.
ok so i then tried to reinstall the first version i had working on the tablet, and that also fails to install saying again application not installed..
why would this be happening? iv noticed that it happens on a fair few number of apps that i install, then uninstall, then try to install again and they fail to install.
installation is done via apk file from sd card. even tried over wifi and still same error.

I know this might sound rude, but did you try Google?

ahh, could be something to do with the certificates or the AndroidManifest.xml file.
where is this file located so that i can check its permissions?

This might be a tough nutt to crack...
"AndroidManifest.xml" file is inside .apk files.

ok i managed to fix the problem. i mounted my sd card to the pc with card reader, and in the android.secure folder there was a file called smdl2tmp1.asec , i deleted that and now the app installs fine. got both jelly defence and few others installed with no issues.
strange how i cant see that folder on the tablet itself because its hidden. need an app to see the folder and its contents directly on the tablet so i can delete it again if needed.

Yeah, folders and files with a dot infront of their names are invisible.
It's a Linux thing!
Glad you got that sorted out!

is there no file manager app that can see these files directly on the tablet?

Just tried "iFileManager" app I got with stock tablet software and it can see hidden files/folders.
I also tried Root Explorer and it can see hidden files/folders, but this is a paid app.
Astro File Manager can also see hidden files/folders, but you need to go into Preferences-->Look and Feel-->and enable "Show Hidden Files" option.
Maybe your current file manager app also has such an option?
Hope I helped, and don't forget to give a thanks!

ahh, i have stock ifilemanager, but i dont use it, i use ES File Explorer since i can access my LAN shares with it easily over the wifi. will give ifilemanager a go in few mins time.
thanks again.

just checked ifilemanager can see the folder but it cant see any of the file which are inside the folder.

Just checked some "hidden" folders myself on my tablet.
Some have files / sub-folders inside and some don't.
Not all folders need to have files inside.

but when i check the folder on the pc via sdcard reader, there are files in the folder.
cant see them directly on the tablet, but when connected to pc i can see the files in exact same location.

Need help with understanding mount-points, folder structure and file system rights...

Hi everyone,
I need your help. I sometimes face strange issues with my Nexus 4 (Stock Room, Rooted, Matrix Kernel v5). Yesterday I wanted to copy a apk-file for installation on my phone from my home-server. I use ES File Explorer for that. I failed to copy the apk-file to /sdcard/folder-name (operation failed). then i navigated to /data/media/0/folder-name and tried it from there, also it didn't work.
i then copied the file to /sdcard/download and was able to copy it to that and to install it.
i don't really understand why it behaves that way, i was always able to go to /sdcard/folder-name and do what i want. i also noticed another strange thing. i connected my phone via USB (MTP-mode) to the PC and uploaded a few GB of MP3s to it (Folder: Music).
when browsing this folder with ES File Explorer, I cannot delete anything from that folder /sdcard/Music. THOUGH it reports "deletion successful" the files or folders do not get deleted but just remain on the internal SD-card. i could only delete the music successfully via "/data/media/0/Music".
who can explain briefly WTF is going on? i obviously do not really understand the concept and logic behind this. is there a maximum file/path length that must not be exceeded?
thanks in advance and best regards,
hallu

need to bump this, sorry...

does anyone have any idea as to why this phone is behaving the way it is?

I use root explorer and have ZERO issues. That includes pulling apk's.

Try a different file explorer to see if that makes a difference so at least you can determine if the issue is just app specific and not something else.
Check to see of ES isn't mounting certain folders with RW permissions.
Also the actual internal storage is /data/media/0/ so /sdcard/ is just a symlink to that folder. ES seems to be having problems with the symlinks.

[SOLVED] Help Me Understand the Folder Structure

(i tried searching for similar threads... this was the only thing i can find sorta close)
i have the 16GB version, and i flashed CM10.1 M2 yesterday. i performed a wipe data so that i could start from fresh.
now i'm trying to restore app settings one at a time. the first one i tried to do was Nova Launcher.
i had connected my tablet to my computer, and copied over my backup to the following:
/Android/data/com.teslacoilsw.launcher/backup/
now when i go to Nova Launcher restore, it can't find it. it is looking for the backup in the following path:
/sdcard/data/com.teslacoilsw.launcher/backup/
so boot up Astro File Manager, and i found the following folders at the root level:
/sdcard/
/storage/emulated/0/
/storage/emulated/legacy/
/storage/sdcard0/
/storage/usbdisk/ (empty)
/usbdisk/ (empty)
the first 4 folders mentioned here all display the same files as if i was viewing them from my computer.
if i navigate to /Android/data/com.teslacoilsw.launcher/backup/ from any of these 4 folders, i'll see my Nova backup file.
i have no idea why Nova Launcher can't see my backup file to restore.
in a related note, i made a CWM nandroid. but when i go to /clockworkmod/ nothing is there except 2 hidden files (nomedia and settings). even tho from within CWM, it sees the backup.
-SOLVED-
in short, don't use Astro File Manager. i started to use ES File Explorer.

Look in /data/media/clockworkmod/backup for your backups.

when i go to the root level- /data/ this folder is empty.
(using Astro File Manager)

In Root Explorer or ES File Explorer you can navigate to /data/media/clockworkmod/backup. I don't know why Astro is not showing it, but I just checked in Astro and can't see it either. Astro is no longer listed as having root access after the latest updates. I can't add it in SuperSU. I think that's the problem for Astro.

yes! problem solved.
i didn't know Astro couldn't navigate to those folders anymore. stopped using that now.
on to ES File Explorer.
found where to put my Nova backups, and i found the CWM backups too.

ADB-puuled CWM backup doesn't match its original size on phone?

Hi all,
I've decided to try and copy my nandroid backup that I made the other day (first ever since I've just rooted my phone) to my PC.
Long story short, I attempted to use Root explorer to cut and paste the backup's folder into a folder that is visible on my PC so I could get a copy onto my PC, and then cut and paste the nandroid back into its original folder (tedious, but I don't have enough space to have 2 copies of the nadroid on my phone at the same time). This, however, fails, and I can't see the backup folder in the folder that I can see on my PC despite it being visible in this same PC-visible folder via root explorer after its supposedly pasted it.
So I went via option 2, using ADB to pull the folder.
After another amount of research I found a path that does pull the folder (mnt/shell/emulated/clockworkmod/backup .... data/media/clockworkmod/backup = remote object doesn't exist error).
It appears to pull the folder successfully (an identically named folder appears in "platform tools" folder on my PC), however the size of this pulled folder is only ~500mb, and I'm certain the nandroid backup took up at least 3-4GB on my phone after it was created.
The pulled folder also doesn't show all the files that I can see within the nandroid backup's folder via root explorer.
I did notice the "read-only" checkbox of the pulled folder appears filled in, which I take it means not all files in the folder have read-only properties. Is it possible there are (still) hidden files within the pulled folder that would account for the difference in size and number of visible files compared to the original nandroid folder on the phone?
any clarificaion of this would be good - I'm keen to have a copy of my backup on my PC as a safeguard, but this scenario has baffled me despite an hr's worth of research

No one?
Surely someone has an idea about this..

I have experienced incomplete adb pulls also, and so I just stick to using MTP from within Windows. It's the only way for mention ensure a complete copy.

How are you doing this?
I use cwm and the backup folder isn't visible if I use mmtp (Windows file explorer etc), hence why I'm having to use other methods.

It's possible that the computer and phone may be calculating file sizes differently. I would check the MD5 sums to see if they are the same on the computer and phone rather than guessing

Apologies for my ignorance, but I've been searching how to do this via Google and I must be really dumb because I'm not following how to do md5 checks. Could you explain it please?

For Windows you need to download a program to check MD5. Microsoft has one available here, although it is a command line operated program. There are other programs that have a GUI for checking MD5 if you don't want to bother with the command line.
On your phone, using your file explorer and long pressing the backup should give you the option somewhere to calculate MD5 sums (Probably in properties). I don't know if root explorer does, I've never used it before, but I use Solid Explorer which does give me the option to calculate MD5 in the properties menu

I'm not sure why you're backup folder isn't visible, when I connect though USB, all my SD card folders are shown, including the CWM Folder.

After a while of trying to work out the command line, I've think I've got it (but would like confirmation that this is correct).
- Pointed the fciv.exe command to the nandroid.md5 file located in the backup folder I had pulled from the phone via ADB
- using Solid explorer (root explorer also has this but I only worked this out after I worked out that I had look at the properties of the .md5 file itself w/in the explorer app, rather than the whole folder), I found the MD5 sum from within the backup folder
-- verdict: both numbers outputted by each source match.
Now my next question is, if I were to delete the backup on my phone, how do I go about putting it back into the "hidden" CWM backup folder where it came from later?
(seeing as I wasn't able to copy it using root explorer, and can't see the folder via MTP on my PC)

I have no idea either, and its really really annoying me.
Have you made some sort of permission changes to the folder/s themselves?
I have "show hidden folders" enabled under view options in windows explorer and have tried "show system folders", but that hasn't resovled it.

You can use ADB push in recovery the folder. Just make sure you mount /data

I do have those settings enabled in control panel, but aside from that I'm not sure what else could be there. In terms of USB settings, I have USB debugging enabled in developer options, and in the storage menu I have mtp selected, not the other one. I think that is all the USB settings that I have changed.

The CWM backup folder shouldn't be able to be accessed with MTP. Android only allows you to access your user's folder (You can only have multiple users on tablets, but the user based file structure is still there) through USB. User folders have a number attached to them to mark which user they are for, which is why you have that folder named 0 with all your stuff in it, because you are user #0. Since CWM backups are saved in a separate branch, Android does not make them available to USB for security reasons. lolcakes203 probably has a modified version of CWM (Or you can change the save directory in CWM? I haven't used CWM in forever), or he has TWRP which saves backups in your user folder so you can access them through USB

Ahh yes I am using PhilZ CWM and that may be why I can see the backup.

Sorry, not sure I'm following the command line instructions - how would this command line look in full?

Can't see TWRP Backups in TWRP Folder

Now i know this is a common-ish issue with some variants as to the actual problem, i should know i've been trying to fix this for the last 48 hours but have eventually had to ask.
I made a TWRP Backup that when I look in the TWRP File Browser i know is stored in /sdcard/TWRP which i think is the same as storage/emulated/0/TWRP which is where i see an empty TWRP folder in both ES File Explorer, File Manager HD and Root Explorer. I've searched and this is the only TWRP folder on the device that is found and i've turned on 'Root Explorer' yet the folder is always empty, in fact ES File Explorer see's it but actually won't let me go into it like the other 2.
I've seen various things about such as Terminal Emulator commands but i can't get this to work, i just want to be able to move the backup to my PC and be done with it (until i have to worry about putting it back)
Can anyone help with how i can get this to work?

Actually finally just solved this. It seems if you connect the phone to your computer while in TWRP, i can see the contents of the TWRP folder. I'm pretty sure i tried this earlier, so maybe all the messing around i've tried since also contributed, but its solved finally.

If You can see TWRP through ES Explorer then Follow Given Steps :-
1. Open ES Explorer and Click on the three lines ( Left side on the top )
2. Now Click on Tools ( it opens many Option )
3. Now You can See Root Explorer Option in it , On it.
4. Now You can copy paste it.
