When you try to install an Android Application using adb and received an error with message as “Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]”
We already have same package system application installed and we tried to install same package’s non-system application.
$ adb install -r ./app/release/app-release.apk
Performing Streamed Install
adb: failed to install ./app/release/app-release.apk: Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE: Package your.app.package.name tried to change user null]In this we already had one system application installed and tried to install the same applications non-system apk and received above error as indicated with message “tried to change user null”.
Solution 1 : Try to change the new apk with system application by modifying AndroidManifest.xml as,
android:process="system"
android:sharedUserId="android.uid.system"and then install the new apk, so we have same user for installed apk and new apk.
Solution 2: We don’t want new apk and system application, then first uninstall existing application and then install new apk.
$ adb shell pm uninstall your.app.package.name
$ adb install ./app/release/app-release.apk
