Gradle: Error: more than one library with package name 'com.google.android.gms'

Question

What does this error message mean? I don\'t have duplicated packages in my project

Error:Execution failed for task \':SimpleReader:processDebugResourc

Answer 1

Try removing compile project(':libraries:googleplayservices') or compile 'com.google.android.gms:play-services:4.2.42'. I am pretty sure they are the same library.
