How to resolve java.util.zip.ZipException?

Question

Whever I try to debug and deploy my android application (in Android Studio 0.9) I get the following error:

Execution failed for task \':app:packageAllDebugCl         


        

Answer 1

To diagnose and fix this problem, run this gradle command:

./gradlew clean app:dependencies

this will list all of the dependencies in your app in a tree. Search the results for the offending duplicate class and add

compile('naughty.library') {
    exclude group: 'foo', module: 'bar'
}

to remove the duplicate.
