Android dependency '..' has different version for the compile (..) and runtime (..) classpath

Question

I migrated to Android Studio 3 and Gradle 4. Then I changed compile to implementation in my build.gradle files. But I get the error:

Answer 1

I upgraded compileSdkVersion & targetSdkVersion to 28 and I also faced this same error.

I upgraded all the dependencies version in app.gradle to 28.0.0 and also in project .gradle file upgraded com.android.tools.build:gradle to 3.3.2

i.e classpath 'com.android.tools.build:gradle:3.3.2'

After this project synced successfully
