For me, the solution was to just migrate to AndroidX.

On Android Studio, go to:

Refactor > Migrate to AndroidX

clean the project.

Just remove the below line:

tools:replace="android:appComponentFactory"

And recompile and finally it works for me!

you should try this:

1:Remove tools:replace="android:appComponentFactory"

2:Provide new value for android:appComponentFactory" attribute

from: Manifest merger failed, error on compiling

it worked for me!

In my case an error in Manifest file brought about this error at the time of generating apk although app was building flawlessly.

It was want of explicit 'exported' attribute in activity elements in Manifest file. after that apk too generated successfully .

I had a similar issue and I have solved by updating Junit dependency from 1.1.3 or later and it solved my problem.

androidTestImplementation "androidx.test.ext:junit:1.1.3"
