I had the same problem after performing the migration androdx. I tried all the above methods but not resolved. I suddenly found that I used com.android.tools.build:gradle version is 3.3. I update it to 3.5. Problem is solved.

project build.gradle: classpath 'com.android.tools.build:gradle:3.3.0' Update to classpath 'com.android.tools.build:gradle:3.5.0' Redo the migration.
