Question

I am getting the exception below when I am trying to run the application using Android Studio:

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

Answer 1

I have same issue, after few hour research, i found a solution to fix it.

You should fixed build.gradle :

android {

    compileSdkVersion ..
    buildToolsVersion '...'

    defaultConfig {
       ...
       targetSdkVersion ..
       multiDexEnabled true  // this line will solve this problem
   }
}

If the number of method references in your app exceeds the 65K limit, your app may fail to compile.
