java – LibGDX HelloWorld project crashes when run on Android emulator

Posted by: admin June 15, 2020 Leave a comment

Questions:

I’ve been trying to get the Hello-World project to run as part of learning LibGDX. Using the Nightly Build (libgdx-nightly-20140322). However, I have become quite frustrated because the hello-world-desktop project will work when run as a Java Application, the hello-world-html project will Run As a Web Application. But hello-world-android simple produces a not very descriptive error:

I have checked on here looking for similar problems and found Android Emulator does not launch LibGDX project?, but the solution given does not work with what I have. There was also libgdx my first triangle tutorial not working?, which pointed me to new tutorials to try, but no avail.

The first time I attempted to follow the tutorial on GITHUB, and the second time Games from Scratch’s LibGDX Tutorial 1: Creating an initial project.
I have tried different API Levels 8, 13, 16, & 19.

Here is the dump of the logfile:

How to&Answers:

As @Sid notes in the comments, the error says LibGDX requires OpenGL ES 2.0 support. The emulator’s software renderer does not support OpenGL ES 2.0.

You may be able to get your emulator to support by enabling graphics acceleration in the emulator. See http://developer.android.com/tools/devices/emulator.html#accel-graphics and Android OpenGL ES 2.0 emulator

Here is the Android Virtual Device Manager dialog with the setting highlighted. Enabling this definitely solves the problem on a Macbook Air, and likely many other computers.

Click Use Host GPU

Thanks.

I have a Samsung Galaxy S-III G4, so I’ve just installed Kies from Samsung and that’s appears to have covered the drivers.

I followed the HowTo Run an android application in a mobile device and the LibGDX Hello-World app works on my device.
