CodePudding user response：

I faced this error in the past and I solved it with below steps.

1. Open gradle.properties files.

2. Now add this two lines

   android.useAndroidX=true

   android.enableJetifier=true

3. Now just Rebuild your project and you are done.

Note - If your gradle.properties files already has android.useAndroidX=true inside then Just add android.enableJetifier=true and rebuild your project.

Hope it works for you too.

What do these two properties do, so according to documentation of android:

android.useAndroidX: When this flag is set to true, the Android plugin uses the appropriate AndroidX library instead of a Support Library. The flag is false by default if it is not specified.

android.enableJetifier: When this flag is set to true, the Android plugin automatically migrates existing third-party libraries to use AndroidX dependencies by rewriting their binaries. The flag is false by default if it is not specified.
