Android Studio Gradle Error:Execution failed for task ':app:dexDebug' using Ion koush lib
问题 I want to use the Ion Lib from koush in Android Studio. But after I synchronize the libraries in my gradle file and try to run the application a strange error occurs. My thought is that the Ion Lib does not accept the other libraries in my gradle file.
