can we see your `dependencies` in your `build.gradle` file. you probably have both `androidx` libraries and `com.android.support` libraries in conflict with each other — user3170251, Apr 23 '19 at 13:22

You have androidx libraries (probably in one of the used libraries) conflicting with the support libraries.

Add these lines into your gradle.properties file: (It's in the root directory of your project)

android.useAndroidX=true
android.enableJetifier=true

The Jetifier tool migrates support-library-dependent libraries to rely on the equivalent AndroidX packages instead.

@civanimahida Are you sure, you are not using any third party library like firebase which is using androidx? – nullvoid Aug 28 '19 at 08:26
thank you I used firebase and when I delete it, I didn't get duplicate error anymore – fasadat Dec 02 '19 at 14:22
For me issue was solved after adding both lines, previously I was added only one line as useAndroidX I think that was causing issue. – nilesh Oct 12 '20 at 08:55

First Select Refractor from top bar then from that select refract to androidx so it will create a zip file for you as a back up.

After that it will automatically be fine and fixes all kind of bugs and errors that are stopping the phone app from running

That's it!! You did it

android.useAndroidX=true

android.enableJetifier=true
