android – INSTALL_FAILED_SHARED_USER_INCOMPATIBLE while using shared user id

Posted by: admin April 23, 2020 Leave a comment


I am working on Android application which will share the database. For that, I’m using android:sharedUserId in both application’s Manifest file. When I am trying to run the application after adding that sharedUserId it shows me following errors in console.

[2013-03-04 19:37:32 - MainActivity] Installation error: INSTALL_FAILED_SHARED_USER_INCOMPATIBLE
[2013-03-04 19:37:32 - MainActivity] Please check logcat output for more details.
[2013-03-04 19:37:32 - MainActivity] Launch canceled!

Please help me to resolve this problem.

How to&Answers:

I followed these steps:

  1. Removed existing application (if it is already installed )
  2. Removed share user ID from android manifest
  3. Bulid the application.
  4. Now enter share user ID again
  5. build the application 1 more time


This means something about your app was not correctly uninstalled. This steps help to force uninstall from internal commands:

  1. Connect your phone to PC with usb
  2. From your shell launch:
    $ adb shell
    [email protected]:/ $ su
    [email protected]:/ # pm list packages | grep <part of package>
    [email protected]:/ # pm uninstall <package>
    [email protected]:/ # exit
    [email protected]:/ $ exit

Basically, you log into android shell, become superuser, find problematic packages, and uninstall it


In my case, the two app was signed with differents signatures. Using the same signature fix my problem


The solution for me was to select the “Build > Clean Project” menu option. It took a long time but the application deployed once it was complete.


Although you have accepted answer, I also want talk my situation which I met this error. My project is a Launcher which just happen to use some system grant like, Manifest.xml have two item:

<uses-permission android:name="android.permission.STATUS_BAR" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

and console log out:

Error using StatusBarManagerService - java.lang.SecurityException on android.permission.STATUS_BAR

Lastly, my colleague give me a hint using “platform debug key”, I am not sure this will be suitable for you, but for another guys possibility for this kind question.
The below picture is my solution:

you might also notice ‘Signing Config’ of “Flavors” and “Build Types”, you might choose ‘Name:’ of “Signing”.


In my case, I had two build variants (one specific for a device, and one general).

I was running the device-specific build on an emulator when this error showed up.


I did a slightly different approach.

My work involves using a modified Android OS along with a modified adb tool. The app (app1) I am working on “shares a user” with another app (app2) by another team. In order for me to get the Android Studio debugger to work, I had to follow these steps in order:

  1. use the Build (from Android Studio Menu) -> Generate Signed APK
  2. build a debug version of apk (app1) with the key store information used by (app1 and app2)
  3. use adb to uninstall the previous apk
  4. use adb to install the signed debug-apk
  5. use adb to launch the app in debug mode
  6. connect the Android Studio debugger to the app


I have encountered the same problem. I tried out everything, but unfortunately, nothing works for me. As it’s a testing device no hesitated to do a factory reset. Oops. sucks didn’t work either. Invalidate Cache/ Restart did the trick eventually. Looks like it’s an Android Studio 3.5 bug.



I was using Emulator and the solution for me was to select the “AVD Manager” and Wipe all data from my Emulator device. After that application was installed.


Simply delete the existing application from mobile and reinstall using run.
