Answer 1

I prefer to write and retrieve data through objects. MyObject is POJO.

@Override
public void onDataChange(DataSnapshot dataSnapshot) {
    for (DataSnapshot data : dataSnapshot.getChildren()) {
        MyObject myObject = data.getValue(MyObject.class);
        Log.i(TAG, data.getKey() + " = " + myObject.toString());
    }
}
