Simultaneous display of two animations in SurfaceView

I'm trying to get two animations to show at the same time. The application builds successfully but crashes in the emulator.

I have created an Anim class in a thread that handles the Animations in a while loop. I think there is a problem with my draw method but I cant seem to figure it out.

I also want the animations to be clickable and get different sounds when the different animations are clicked.

I have successfully implemented SoundPool to an OnClickListener that I attached to the view because I can't seem to get an OnClickListener to each animation, but this obviously sets an OnClickListener to the entire screen so I get the sound effect playing no matter where the user taps the screen.

I appreciate any help on this, thank you

CODE

public class PlayActivity extends AppCompatActivity {    private SoundPool soundPool;  private int sound1;    surfaceView view;          @Override  protected void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      view = new surfaceView(this);        setContentView(view);            AudioAttributes audioAttributes = new AudioAttributes.Builder()              .setUsage(AudioAttributes.USAGE_ASSISTANCE_SONIFICATION)              .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)              .build();      soundPool = new SoundPool.Builder()              .setMaxStreams(5)              .setAudioAttributes(audioAttributes)              .build();          sound1 = soundPool.load(this, R.raw.eagle, 1);            view.setOnClickListener(new View.OnClickListener() {            @Override          public void onClick(View v) {                soundPool.play(sound1, 1, 1, 0, 0, 1);          }      });  }    public class surfaceView extends SurfaceView {          public surfaceView(Context context) {          super(context);          new Anim().start();              }          private class Anim extends Thread {          int counter = 0;          int counter2 = 0;                @Override          public void run() {              long last_updated_time = 0;              long delay = 250;              int[] purple_bird = {                      R.drawable.bird1,                      R.drawable.bird2              };              int[] red_bird = {                      R.drawable.red1,                      R.drawable.red2,                      R.drawable.red3,                      R.drawable.red4              };                  while (true) {                  boolean playing = true;                  if (playing) {                        long current_time = System.currentTimeMillis();                      if (current_time > last_updated_time + delay) {                          if ((counter >= 2) && (counter2 >= 4)) {                              counter = 0;                              counter2 = 0;                              }                          draw(purple_bird[counter], red_bird[counter2]);                            last_updated_time = current_time;                          counter++;                          counter2++;                      }                  }              }                  }            private void draw(int red_bird, int purple_bird) {                SurfaceHolder holder = getHolder();              Canvas canvas = holder.lockCanvas();                if (canvas != null) {                  canvas.drawColor(Color.WHITE);                  Paint paint = new Paint();                    Bitmap purpleBird = BitmapFactory.decodeResource(getContext().getResources(), purple_bird);                  Bitmap redBird = BitmapFactory.decodeResource(getContext().getResources(), red_bird);                      Bitmap resizedRedBird = Bitmap.createScaledBitmap(redBird, (int) (redBird.getWidth() * 0.4), (int) (redBird.getHeight() * 0.4), true);                  Bitmap resizedPurpleBird = Bitmap.createScaledBitmap(purpleBird, (int) (purpleBird.getWidth() * 0.2), (int) (purpleBird.getHeight() * 0.2), true);                    canvas.drawBitmap(resizedRedBird, 500, 500, paint);                  canvas.drawBitmap(resizedPurpleBird, 100, 100, paint);                    holder.unlockCanvasAndPost(canvas);                      }            }      }            }
