Answer 1

Whenever user is in your app, technically he is online. So in your home activity use this:

  @Override
    protected void onStart() {
        super.onStart();
        myRef.child(uid).child("isOnline").setValue(true);
        myRef.child(uid).child("isOnline").onDisconnect().setValue(false);
    }

and also i would suggest to add to override onResume():

    @Override
    protected void onResume() {
        super.onResume();
            myRef.child(uid).child("isOnline").setValue(true); //User back online

        }

Make sure to add an if statement to check if user is connected to internet or not!
