Answer 1

To solve this, please use the following code:

firebaseAuth = FirebaseAuth.getInstance();
mDatabase = FirebaseDatabase.getInstance();
mDb = mDatabase.getReference();
FirebaseUser user = firebaseAuth.getCurrentUser();
userKey = user.getUid();

mDb.child("Tunanetra").child(userKey).addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        String userID = dataSnapshot.child("user_id").getValue(String.class);
        Log.d(TAG, "Name: " + userID);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {}
});

With this code, you'll be able to print out in the logcat, the id of the users that is authenticated and exists under Tunanetra node. If the user exists under the Orangtua node, then just change Tunanetra with Orangtua.
