Cannot see image on Screen (Using #AndEngine)

Question

I am trying to create a simple object (an image, player.png) moving around. My code is below, i see the correct background color, but i do not see the image.

My screen (on Galaxy S3) looks like this:

It should look like:

The player.png is correctly under the gfx folder under assets (assets/gfx/player.png).

The code compiles and runs on the phone without any errors.MyBringBack TUtorial Here

    sPlayer.attachChild(sPlayer);

}

Is something wrong with my camera settings?

Answer 1

 sPlayer.attachChild(sPlayer);

change above line in your code with

 scene.attachChild(sPlayer);
