Doesn't work on Lineage OS 14.1 (Android 7.1.1)

[CarbonFixer]

When trying to move an app, there is an error: "could not remount /system" logcat: 01-05 21:35:55.982 23781 23781 W .systemappmover: type=1400 audit(0.0:149): avc: denied { read } for name="RootToolsMounts" dev="dm-0" ino=654083 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:system_data_file:s0 tclass=file permissive=0 (sorry - accidentally clicked enter on the original report with only the title)

I just assume these system app moving apps will never work right. Wish it would just be removed from f-droid.

The problem is RootTools library (https://github.com/Stericson/RootTools/blob/master/src/main/java/com/stericson/RootTools/internal/Remounter.java#L119) generates this command:

mount -o remount,rw /system

While the newest lineageOS needs this command:

mount -o rw,remount /system

I hope someone fill fix this since the problem is located

Any alternative for LOS 14?

[derlaft]

I am not sure if it works, but try OpenAPK

[IvanTurgenev]

OpenApk doesnt have that function could be possibly easily implemented

Manually remounting /system rw before running the app isn't working either :(

[IvanTurgenev]

There is a manual method it works but its a pain in the ass

Yalp Store (available on f-droid) does it.

[AntumDeluge]

Yalp works alright. Some apps seem to disappear after moving them from system.

Since RootTools hasn't been changed, I suggest making a patch that doesn't try to mount/remount system if it is already mounted as RW. I might try to do it myself, but not sure it's within my capabilities.

@derlaft Have you also tried on Android Q ? For some reason it fails to convert apps to be system apps on my case. Can you please share your solutions for converting to system app and back to user app? Please?

@IvanTurgenev

What is the method exactly?

[AntumDeluge]

@timaschew I'm guessing that @IvanTurgenev is referring to manually moving the apk packages to the system directory with a file manager or via command line.

[AndroidDeveloperLB]

@AntumDeluge Did you succeed doing it? Have you also tried on Q ?

[AntumDeluge]

@AndroidDeveloperLB Succeeded at creating the patch? No, I haven't even tried it yet. Have had other things I'm working on at the moment.

[AndroidDeveloperLB]

@AntumDeluge No. I mean if you succeeded doing it manually. Also, if you know how to convert an app to be a system app and back even on Android Q.

[AntumDeluge]

All you have to do is move the directory that contains your .apk to the /system/app or the /system/priv-app directory, then restart your device. So, for example, let's say I have an app on my device. Its .apk is located in /data/app/com.foo.bar. So in a terminal with root permissions I would just do the following:

# mv /data/app/com.foo.app /system/app

Then I would restart my device. I believe it can be done in an adb shell as well.

If your file manager supports getting root permissions (Amaze is one), you can just move it with that.

One small caveat to making your apps system apps is that updates are not installed to the /system directory automatically. It's still considered a system app, it's just that the update .apk is stored in the /data/app directory (or wherever the standard installation directory for your device is). So, if you don't want the update .apk taking up extra space on your device, you have to move it again, replacing the old .apk.

I don't know anything about Android Q though.
