Android Manifest merger failed || Manifest merger failed with multiple errors, see logs

Question

I am working on a App using Firebase. I got a issue which needs to get solved. When i go to run the app it shows in build .

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:10:5-31:19 to override.

I searched the whole internet to solve the issue failed. I also added

tools:replace="android:appComponentFactory"

in the AndroidManifest.xml file. I also followed the answer of This Question. but it didn't work for me saying

Manifest merger failed with multiple errors, see logs

Answer 1

Just a tip, in the bottom of the manifest you can access the "Merged Manifest" to check the errors.

If you can't figure out the erros, post your manifest so we can help.

Answer 2

-Try adding this lines to application tag in manifest.

    tools:replace="android:appComponentFactory"
    android:appComponentFactory="androidx"

Answer 3

Actually i was using implementation 'com.theartofdev.edmodo:android-image-cropper:2.8.+' and the android-image-cropper:2.8.+' is Update to support library to AndroidX . So i just changed the version to this

implementation 'com.theartofdev.edmodo:android-image-cropper:2.7.0'

Now the app is working fine.
