I would like to create an instant app for one application currently on the play store.
For that, I made dynamic feature modules with all necessary things for instant experience.
The major problem is that the field android:sharedUserId is defined on main module.
When testing my work, we get the following error on logcat :
android.content.pm.PackageParser$PackageParserException: /data/app/vmdl143761699.tmp/base.apk (at Binary XML file line #2): sharedUserId not allowed in ephemeral application
This means that an instant app cannot work with sharedUserId field...
When I remove this field, my instant app works very well, but I cannot install main application or update previous installation version, I obtain this error :
E/Finsky: [2] zdp.onReceive(15): Error -505 while installing xx.xx.xxx.xxx: INSTALL_FAILED_SHARED_USER_INCOMPATIBLE: Package xx.xxx.xxxx.xxx tried to change user null
Ok, Google specify that is not possible to delete this field without application reinstal... (https://developer.android.com/guide/topics/manifest/manifest-element#uid)
So I could not have an instant app as long as I have sharedUserId field and I cannot delete it...
Is there any solution for my problem ?
