在Android模拟器上运行时，LibGDX HelloWorld项目崩溃 [英] LibGDX HelloWorld project crashes when run on Android emulator
问题描述
我一直试图让Hello-World项目作为学习LibGDX的一部分来运行。使用Nightly Build（libgdx-nightly-20140322）。然而，我已经变得非常沮丧，因为hello-world-desktop项目将作为Java应用程序运行时工作，hello-world-html项目将作为Web应用程序运行。但是hello-world-android simple产生一个不是很描述性的错误：
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:
我在这里检查了类似的问题，发现 Android模拟器不启动LibGDX项目，但是给出的解决方案与我所拥有的不一样。还有 libgdx我的第一个三角形教程不工作？我尝试新的教程，但无济于事。
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.
我第一次尝试按照 GITHUB ，第二次是Scratch的 LibGDX教程1：创建初始项目。
我尝试了不同的API级别8，13，16，& 19。
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.

推荐答案
由于@Sid在注释中注释，错误说LibGDX需要OpenGL ES 2.0支持。仿真器的软件渲染器不支持OpenGL ES 2.0。
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.
您可以通过在仿真器中启用图形加速来获得您的仿真器的支持。请参阅 http://developer.android.com/tools/devices/emulator .html＃accel-graphics 和 Android OpenGL ES 2.0模拟器
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
这是Android虚拟设备管理器对话框，突出显示设置。启用此功能绝对可以解决Macbook Air上的问题，以及许多其他电脑。
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.
