Augmented Reality Example Not Working

[Henry]

When I run the andengine examples app and try the augmented reality feature, it works perfectly with the sprite showing. However, I made my own project and added the augmented reality jar to the build path... The camera shows, but no sprite. I read the note about starting the phone in landscape mode but it still doesnt work. When I click the back button, I see the sprite on a black screen for a second before the application quits. Any ideas?

I had the same issue on my Droid. It looked like the "face" sprite was transparent, with the background camera image showing through this sprite, even when I set the scene's background color alpha to opaque.

I played with setting the "face" alpha to 1.0f (100% opaque) but nothing changed. I had success with setting the "face" sprite's alpha to almost-opaque, right after it is created, as below:

face.setAlpha(0.9f);

Not sure of the underlying reason for the sprite transparency effect in this case.

Same here. If i build Augmented reality demo i get the same error.

Delete this.mRenderSurfaceView.bringToFront(); in BaseAugmentedRealityGameActivity's onCreate() method~~
It works, good luck!
