There are already many items on this topic and i have read a lot of them but without any succes.

In my Merged Menifest the following error

Merging Errors: 
Warning Package name 'android.support.graphics.drawable' used in: AndroidManifest.xml, AndroidManifest.xml. 
animated-vector-drawable:28.0.0 manifest 
Warning Package name 'androidx.versionedparcelable' used in: AndroidManifest.xml, AndroidManifest.xml. 
support:versionedparcelable:28.0.0 manifest 
Error: Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from 
AndroidManifest.xml:22:18-91 is also present at AndroidManifest.xml:24:18-86 value=(androidx.core.app.CoreComponentFactory). 
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:20:5-83:19 to override. 
TripMemory.app main manifest (this file), line 21

Now the warning annoy me but lets leave them for now.
The error is the problem and i have no clue what the problem is.
It suggests to add a “tools:replace…” but when i do that i just get the next error and besides it feels like bypassing the issue and not solving it.

I also don’t understand why i am getting error’s I did not update studio and i was just fixing some layout things. not even error’s just improvements.
It then first started with AndriodX messages. and then this. Maybe that’s a clue for somebody.

my AndroidManifest.xml

                <category android:name="android.intent.category.LAUNCHER" />
                ....
