edit

hello everyone i had a problem running ros_image_transport tutorials in android.It compiled without any errors but when i try to subscribe to topic published by ros computer it doesnot show any images in android apps.I had tried to use logcat also,Nothing displayed to logcat.But when i tried to connect to ros master uri it connects. My cod is:

public class ImageTransport_Main extends RosActivity {

  private RosImageView<sensor_msgs.CompressedImage> image;

  public ImageTransport_Main() {
    super("ImageTransportTutorial", "ImageTransportTutorial");
  }

  @SuppressWarnings("unchecked")
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_imagetransportros);
    image = (RosImageView<sensor_msgs.CompressedImage>) findViewById(R.id.imagess);
    image.setTopicName("/camera/image_raw/compressed");
    image.setMessageType(sensor_msgs.CompressedImage._TYPE);
    image.setMessageToBitmapCallable(new BitmapFromCompressedImage());
    Log.d("main", "onCreate: sssssssssssssssssssssss"+new BitmapFromCompressedImage());
  }

  @Override
  protected void init(NodeMainExecutor nodeMainExecutor) {
    NodeConfiguration nodeConfiguration =
        NodeConfiguration.newPublic(InetAddressFactory.newNonLoopback().getHostAddress(),
            getMasterUri());
    nodeMainExecutor.execute(image, nodeConfiguration.setNodeName("android/video_view"));
  }
}
