INSTALL_FAILED_SHARED_USER_INCOMPATIBLE while using shared user id

Question

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.

Answer 1

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     shell@android:/ $ su     shell@android:/ # pm list packages | grep <part of package>     package:com.android.providers.applications     package:com.android.providers.calendar     package:com.android.providers.contacts     package:com.android.providers.downloads     ...     shell@android:/ # pm uninstall <package>     shell@android:/ # exit     shell@android:/ $ exit     $ 

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