Question

I\'m trying to create a signed APK, but an error will appear at the end:

Error:Execution failed for task \':app:transformClassesWithJarMergingForRele

Answer 1

This may be due to different versions of the support library being used. Add the following in your build.gradle

configurations.all {
   resolutionStrategy {
       force 'com.android.support:design:27.0.2'
       force 'com.android.support:support-v4:27.0.2'
       force 'com.android.support:appcompat-v7:27.0.2'
   }
}
