}

dependencies {
    compile files('libs/crashlytics.jar')
    compile files('libs/cup-v1.0.0.jar')
    compile files('libs/support-v4-r12.jar')
    compile files('libs/gson-2.2.4.jar')
    compile files('libs/google-play-services-0.6.0-sources.jar')

Answer 1

Your problem is your are compiling two libraries that are the same:

compile files('libs/google-play-services-0.6.0-sources.jar')
compile 'com.google.android.gms:play-services-wearable:6.5.87'

You need to chose one Google Play Services , preferably the Maven Dependency and not the .jar.

Try this:

dependencies {
    compile files('libs/crashlytics.jar') // couldn't find maven
    compile files('libs/cup-v1.0.0.jar')  // couldn't find maven
    compile 'com.android.support:support-v4:21.0.3'
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'com.google.android.gms:play-services-wearable:6.5.87'
}
