I tried updating google maps today and it kept saying the package was not signed correctly. Upon researching the issue, I decided to delete the Maps.apk and Street.apk from system/app and trying to install from market after reboot. I tried to install and I got the code "unknown error code during application installation "-8"". I tried to move the downloaded apk from cache to system/app and renaming it Maps.apk and rebooting and that didn't work. When I try to hit install, it asks me if the permissions are ok, I hit install and it says application was not installed. I've deleted the com folders and every trace of maps I could find through root explorer to try to start fresh and no such luck. Can anyone help out?
Use the non signed version, it has always worked for me, but don't install it as a regular app, just copy the Maps.apk to system/app , change permissions to rw--r--r and reboot, all the applications should appear...
most like its because the modded rom you flash uses the unsigned version so it can't be updated. If I were you I would have stick with the unsigned version. If you don't want to reflash, you could extract the unsigned map.apk from the rom you flash and manually install it. It SHOULD work.
(Preface for noobs : /system and /data are two different partitions. Freeying up /system won't get you more intrenal memory, but /data does. Old apks rest in /system and updated versions placed in /data. You can replace the old apks using newer versions)
I heared Titanium Backup PRO does something like, but you can do this with any File Explorer with ROOT access. Its works 100% for Android Gingerbread 2.3.x , try on other versions.
### Do it on your own risk, I am not responsible for anything ###
1. Update the desired app to the latest version from Google Play Store
2. Open File Manager, Enable ROOT_ACCESS, remount /System as writable
3. Goto /system/app and backup the desired apk to sdcard
4. Goto /data/app and copy updated apk
5. Paste into /System/app
6. Note down the filename of old apk and delete the old apk
7. Rename the new apk into the old filename
8. You may encounter a FORCE CLOSE if the app was running in background
9. The updated apk in /data/app will be removed automatically
10.Restart your device, Done!
I replaced Playstore, Maps, Google Search ect..
Example: For PlayStore, updated apk will be com.android.vending-1.apk, and old apk is vending.apk
Hit thanks it it works, Thanks
thanks, nice guide! All is ok (PlayStore, Terminal Emulator), but if I merge last version of "Google Play Service", then Gmail or Maps shows the message "Unknown issue with Google Play services" when I open them... do you know how to solve? thanks in advance
p.s. configuration in signature
Better use Link2SD. It makes the integration of updates into system seamless. Rebooting the device is optional (restart only if you encounter errors).
thank you for your suggestion! I tried TitaniumBackup but it gives me the same error, then now I'm trying with Link2sd and it works well, BUT the new apk file is in system/app instead of system/priv-app, and its name is "com.google.android.gms-1.apk" instead of "PrebuiltGmsCore.apk"... can this create some problems in future?
EDIT: I tried moving to the priv-app folder and renaming the apk to be identical as before and it seems to work... for now...
It's the package name, it won't create any problems. There is no need to rename the app to match the old one. Default location when converting to system app is in /system/app. I don't know if you can change the location, but you can move it manually to /system/priv-app thru root explorer. Just restart the device afterwards to eliminate FC errors.
I uninstalled the stock whats app from my Xolo Q500s. i cant install any other apk of whats app.. Even play store refuse to install what app.. Is there any other way install it..?
Hello, try move apk to /system/app or /system/priv-app and make good permissions
Hi,
I recently used "System App Remover" and deleted a system app "amigo_dynamicweather.apk". That app did not create a backup before deleting it. Anyways, I got that apk somehow but when I try to install it manually, I get "App not installed". So I tried to install it by moving it to system/app folder and set permissions to RW-R-R using root explorer, rebooted and nothing. App was in the system/app directly but I cannot see it installed. The permissions still are RW-R-R. How can I install it? Please help.
I have a rooted OP6 with Oxygen OS 11.1.1.1 and I accidentally deleted the Stock Files app thinking it was Google Files installed as a system app. How do I get it back. I tried using terminal systemizer to reinstall it but if I choose /system/app it says it already exists and if I choose /system/priv-app it installs but crashes upon launch. I got the APK file from ApkMirror. Both Files version 9 and Files beta version 10 don't work. How can I get it back?
Edit: Figured out how to get it back
Just get Terminal Emulator from the Play Store and enter the following commands.
su
Then
cmd package install-existing com.google.android.documentsui
(It's one command I don't know why it split up)
This works for any other system app too, just replace com.google.android.documentsui with any other package name.
