[Q] Why I can't upgrade system apps? - Android Q&A, Help & Troubleshooting

My phone runs Froyo and it is rooted.
A few months ago, I have installed in system/app the application ES File Explorer and it was working fine.
I am now trying to upgrade this app to a newer version. It seems to have installed OK but everytime I launch the app, I get the "Sorry I can launch the ...." error.
It looks like there are files felt behind from the previous version interfering with the newer version. This is the third apps I am trying to upgrade in the system/app folder and they all failed. New applications work, all upgrades fail.
I have deleted the dalvik folder and checked the /data/data folder for any files related to the previous version.
For the record, the newer ES File Explorer installs and works OK when installed on the phone or moved to SD card. It is just when it is moved to the system/app folder that it crashes. I have uninstalled the app before moving it to the system/app folder.
As it stand now I will never be able to upgrade applications stored in the system/app folder.
Any insight as of why I can't upgrade apps?
Thanks

Exploring files

So I'm new to android and the tb but managed to root mine and have some fun, but how do I go about finding all files associated with a particular program? Specifically I uninstalled what I thought was Visual voice mail, but to my surprise it remains. Any help?
Thanks

You can try different file managers, astro pro or root explorer.
Use root explorer or astro, as stated above. Apps that came pre-installed on your phone are located in the /system/app folder, while apps that you installed yourself are in /data/app. If you are trying to uninstall something from the /system/app folder, I would recommend just renaming the apk from "appname.apk" to "appname.apk.bak" (This essentially uninstalls the app, while backing it up).
Some apps in the system folder can cause problems if they are renamed. If you do have any problems from a renamed app you can just use adb from recovery to remove the ".bak" extension and you are back to square one! If you are worried about space, you can go ahead and delete the file completely as long as you have successfully rebooted with no issues after renaming the file(s). Hope this helps!
Thanks a lot, I'm as far from a programmer/developer as you can get but I'm excited to learn now that I finally have a phone worth voiding the warranty on!

[Q] Can't Install New Stage UI?

I downloaded the new Stage UI from another thread. I shoved it onto my SD and attempted to just replace the current stage UI apks but it gave me "application not installed"
I deleted the Stage UI files in titanium backup and made sure they were gone in the system app folder. I rebooted and attempted to re-install from the SD card but the phone still acts like the files are there (gives me are you sure youwant to replace the application?)
I then just moved all the files into system>app with root explorer and rebooted. still nothing.
Anyway around this?
Have you tried copying the new files to the correct locations and setting the permissions (check to see what the other apps have)? Make sure you have a backup before messing with the files.

[Q] installed app. app disapeared. cant reinstall

ok.... I have Samsung Fascinate.
PWGB2.0 beta3 ROM
I found the zip containing on here(XDA) somewhere containing the BuddiesNow app for my phone and installed it. I then found the BuddiesNow for Vibrant tweaked for the Fascinate. I went to /system/app and located my BuddiesNow I had placed in there 1st and renamed it .bak
I then placed the Vibrant BuddiesNow app in the /system/app folder.
It worked great. I discovered I liked the Vibrant BuddiesNow app much better.
*************
ok... now my issue. I picked my phone up ealier this week and went to use my Vibrant BuddiesNow app and it was gone. I then long pressed the blank screen and pressed Widgets from the list that popped up. I scroll thru the list and BuddiesNow does not show up in the list.
I then open my file manager and navigate to /system/app folder and BuddiesNow is not in there. Not even the .bak file version.
I then go to my SDcard and find the copy of the Vibrant BuddiesNow app I had originally stored in a folder there and tried to copy it to the /system/app folder. The error message pops up saying that the file already exist and cant paste the file here.
I then booted into recovery, tried wiping partition cache and dalvik cache.
That did not help any. Got same result when I tried to move the file to /system/app folder again.
I then thought I would be cleaver and rename the Vibrant BuddiesNow in my SDcard folder to [BuddiesNow.apk.grid] and then move it to the /system/app folder. AND THEN AFTER PLACING IN THE /system/app FOLDER, RENAME IT TO .APK
That did not work either! It also diappeared.... now I have BuddiesNow.apk,
BuddiesNow.apk.bak, BuddiesNow.apk.grid, all in the /system/app folder and all invisible.
I had the file manager settings to SHOW HIDDEN FILES from the beginning.
I also have tried the SEARCH function in the file manager but it shows no results. I have tried installing many file manager apps and attempting to see if a different file manager would show the files but none did.....
I tried to write this episode as short as possible.. this is the best I could do to cover al the bases...
what could be a fix????????? PLEASE ADVISE! I LOVE MY BUDDIESNOW!
Come one...anyone? I love my buddiesnow app. Please help me out here
hard to belive
hard to believe someone has not seen this before and has an idea how to fix it...
I love this forum anyways

OVERWRITE FILE is not an option to choose... in this particular problem with this
particular apk disappearance, the option to overwrite is not there.
I have had the overwrite option at other times but not now with this issue fo who know what reason.
I am going to factory reset I guess and start over.
hasn't anyone else had the same issue?
Not sure if this would be helpful but when I had a similar issue I just used titanium backup and found the file that "already existed" and removed it. Also, you can use any file manager that allows you to sort by date modified and look for any buddynow files that may be in a folder that you didn't think about looking in
did you maybe moved the app to your sdcard ? sometimes app's widgets wont show if you move them to sdcard.If you did so move it back to the phone's memory

I used the search function in the various file managers I have tried & even searched the entire phone (and also the /system/app )for he disappeared files and got no results...when I get some time next week I am going to sit down and factory reset my phone and start all over.
if it works I will not try the vibrant version of buddiesnow on my phone again,
I will just use the fascinate version of buddiesnow. (the vibrant version sure was nicer tho)....

[Q] looking for the apk files that was downloaded from playstore

Hi
I'm getting the new s 3 and I want to install all the same software I currently have on my s 2. Some of the software is no longer available in the play store so I'm trying to find out where the apk files that you download from the play store are downloaded to. So does anybody know the file path... Oh i'm running OS 4 ice cream
If you phone is rooted then you can go into root\data\app and find the apks. And again, if you're rooted then a better way is to just use Titanium Backup. If not rooted then redownload the apps.
Play store will display all the apps you have downloaded, if u r going to use the same Google id. This has helped a lot while changing roms.
Go backup is available in the market, it doesn't require root for backing up apks.
I can't see them in this directory

The folder is actually /data/app. Not root/data/app.
And if you don't have root, I don't think you'll be able to see anything in the folder. (or in the data folder at all, for that matter)
Under /data/app you'll find a few hundred folders, one for each app you have installed. They also may have been moved to the external sdcard if you chose to do so.
The best option, IMO, to have the APK files readily available is to install ES Explorer (free, available at the Play Store), and use to backup all the applications to the external sdcard. This way you can simply get all the ready-to-be-installed APK files from a single location, instead of having to iterate through each of the directories in /data/app (which is a PITA).
I use ES Explorer not only to backup all the APKs to a single location, but also to backup different versions of the same app, because ES Explorer suffixes the name of the APK with its version number.
A lot easier and quite more practical.
BTW, you don't need root to use that feature of ES Explorer.

There shouldn't be any folders in /data/app

Try this: Install "Wondershare MobileGo" to PC,after you have installed, connect your SGS2 with WiFi or USB cable to PC and export app. to PC. Then Connect SGS3 with WiFi or USB cable to PC and install the same app from PC to your phone...It is easy to do...

Thanks for all the different methods I ended up use the explorer one.
Didn’t use ES Explorer as I had astro already installed so I used that.
One more function I didn’t know it had
Thanks again

Need help with android custom system apps

So I wanted to make some apps a part of my system apps. I placed the ES File Explorer application in the /system/apps/ directory and when I factory reset the phone, it was installed as a system app and it ran without a problem.
Now when I put Microsoft Office application in the /system/apps/ directory, it crashes . So my question is that how can I make this app a part of the system apps such that it runs without a problem when I factory reset the phone. I also changed the permissions of the app when I place it in the /system/apps/ directory but it crashes.
