How I resolve this error for libraries .which library version I change for it.
I am getting version crashes issue for aome libraires but I am unable to resolve it.
I keep getting the Cannot resolve class android.support.v4.widget.DrawerLayout error even after adding both the DrawerLayout androidx.drawerlayout:drawerlayout:1.1.1 and Material com.google.android.material:material:1.0.0 implementations in my build.gradle file.
I have tried adding other implementations, such as com.android.support:support-compat:28.0.0 and com.android.support:design:25.0.0, but the error remains and the app won't start.
Any idea on how to fix this?

You've imported the wrong version of DrawerLayout. android.support.v4.widget.DrawerLayout
It should be import androidx.drawerlayout.widget.DrawerLayout
Check the class mapping between the support libraries and androidx libraries:
android.support.v4.widget.DrawerLayout -> androidx.drawerlayout.widget.DrawerLayout
Use in your layout and in your code androidx.drawerlayout.widget.DrawerLayout.
While adding dependency implementation 'com.android.support:recyclerview-v7:28.0.0' to my project, Android Studio throws exception ERROR: Failed to resolve: recyclerview. Then I tried adding dependency for recyclerview. Still getting same error.

}
Try this
implementation 'androidx.recyclerview:recyclerview:1.1.0'
Your project migrated to android x
Use this:
implementation 'com.google.android.material:material:1.0.0'
Instead of
implementation 'com.android.support:design:28.0.0'
Then you don't have to implmenet different library of Design. It will add all library.
my App suddenly started to build another app on my phone with the real one ..
and the two are opening the same app
and when i remove one the other is removed also
so what is the problem
why its doing this

Double check your AndroidManifest.xml file for two main activities. Typically an app will only have one activity with an intent filter with a main action and launcher category.
I keep getting the same error and the app stops working when I try and select an image to upload for user using google firease firebaseAuth on android. Here is the error I keep getting: Caused by:
