In my nexus 5 I have get only warrning, but another devices not complied, so I have disabled debug mode if i need it /

buildTypes {
    release {
        debuggable false
        minifyEnabled true
        proguardFiles 'proguard-android.txt', 'proguard-rules.pro'
    }
    debug {
        debuggable false
        minifyEnabled false

    }
}

Something you can try is deleting the build folder. That does not always work but fixes it sometimes.

rm -rf cart/build

If that does not work. Run that command then in Android Studio select invalidate caches and restart.
