The workaround in logtofile.gradle : dependencies { compile ‘com.github.tony19:logback-android-core:1.1.1-6’ compile(‘com.github.tony19:logback-android-classic:1.1.1-6’) { exclude group: ‘com.google.android’, module: ‘android’ } compile ‘org.slf4j:slf4j-api:1.7.21’ }

Finally found it, @sherlockat was correct. Altought it took me some time to find out where you could change that.

It’s found in /platforms/android/app/build.gradle

set the following values:

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
}
