I have LG optimus Black.

I have the following settings:

1. USB debugging on.
2. Unknown applications checked.
3. Driver installed.
4. The app is deployed on Android 2.1 an the phone has Android 2.2. So no problems there I guess.

In fact, it was working fine till some time ago.

But its not showing up now. Any ideas why? Thank you.

Try reinstalling the driver. Worked for me.
