Try this:

DatabaseReference databaseReference = Firebase.getInstance().getReference();
Query lastQuery = databaseReference.child("mp").orderByKey().limitToLast(1);
lastQuery.addListenerForSingleValueEvent(new ValueEventListener() {
    public void onDataChange(DataSnapshot dataSnapshot) {
        String message = dataSnapshot.child("message").getValue().toString();

    public void onCancelled(DatabaseError databaseError) {
        //Handle possible errors.

Hope this helps!
