delete just user-data from application

adb shell pm clear ch.christofbuechi.xyz

non-root: extract database from application

adb backup -f /tmp/data.ab -noapk ch.christofbuechi.tuningeventsschweiz (you have to agree on the device itself)
cat /tmp/data.ab | (dd bs=24 count=0 skip=1; cat) | zlib-flate -uncompress > appbackup.tar
tar xvf appbackup.tar
(show files in explorer, database is in "db"-folder)

fragmentmanager show fragments in stack

int intValueOfChar;
String targetString = "";
while ((intValueOfChar = read.read()) != -1) {
targetString += (char) intValueOfChar;
}
read.close();
Log.d(this.getClass().getName(), targetString);

Let Android Studio fetch the sources with gradle

add:

apply plugin: 'idea'

idea {
   module {
       // if you hate browsing Javadoc
       downloadJavadoc = false

       // and love reading sources :)
       downloadSources = true
   }
}
