I am using ./gradlew assembleRelease command to generate release apk for the app.On installing the app I am getting 2 icons of app.No clue what am I missing.No luch
My top guess is that there is more than one LAUNCHER activity, and that one of them is declared in a library project. Eclipse didn't merge the manifests, but Gradle does.
So, I would suggest you search for android.intent.action.MAIN in all AndroidManifest.xml files.
