Emulator says Stop aplication what is that problem. How can I solve

You can’t run opengl stuff on the computer emulator. Which meens, jme wont work on the emulator.
I connect my phone through usb to debug my apps.

It works now if you don’t do too fancy stuff.

You should do the following:

  • Use the latest system image (ARM) for Android 4.2
  • Turn “Use host GPU” on

Ask again here if it doesn’t work.
