libgdx android failed on launch

问题

This is my first time using libgdx and I would like to try the default application provided after the setup gdx-setup-ui. It runs fine when I hit the run button on eclipse as it has shown

[2014-05-01 21:40:14 - my-gdx-game-android] Uploading my-gdx-game-android.apk onto device 'emulator-5554'

but on the emulator it said unfortunately, my LibGDX Game has stopped.

These are shown in the logCat:

Also, I have deleted the line cfg.useGL20 = true; in the MainActivity.java as it keeps giving me error and I tried to quick fix it, it does not work. I really need it to be used in an emulator as I does not own at android device.

回答1:

I was able to make this work on a Macbook Air by:

open the Android Virtual Device Manager (e.g. in Eclipse this is under the Window menu)
click Edit for the device you want to work with
in the resulting dialog check the box "Use Host GPU" as shown
