I had same problem. What I did was to follow VLC's own example (https://code.videolan.org/videolan/libvlc-android-samples) and make same build.gradle etc.

My code is below:

MainActivity.java

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

import tools.nubicam.com.rtsptest.R;


public class MainActivity extends Activity {

    public final static String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {


        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button startButton = (Button)findViewById(R.id.buttonStart);
        startButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent intent = new Intent(MainActivity.this, VideoActivity.class);
                EditText textRTSP = (EditText)findViewById(R.id.textRTSPUrl);
                intent.putExtra(VideoActivity.RTSP_URL, textRTSP.getText().toString());
                startActivity(intent);
            }
        });

    }

}

VideoActivity.java

import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;

import android.widget.Toast;

        // Get URL
        Intent intent = getIntent();
        rtspUrl = intent.getExtras().getString(RTSP_URL);
        Log.d(TAG, "Playing back " + rtspUrl);

        mSurface = (SurfaceView) findViewById(R.id.surface);
        holder = mSurface.getHolder();
        //holder.addCallback(this);

Please try this one:
```
--- libvlc = LibVLC.getInstance();
+++ libvlc = new LibVLC();
```
P.S. What version of LibVLC-android you are using?

P.P.S. example
