在Android模拟器上运行时，LibGDX HelloWorld项目崩溃

Question

我一直试图将Hello-World项目作为学习LibGDX的一部分来运行。使用Nightly Build（libgdx-nightly-20140322）。但是，我已经变得非常沮丧，因为hello-world-desktop项目在作为Java应用程序运行时将起作用，hello-world-html项目将作为Web应用程序运行。但是hello-world-android simple会产生一个不太具描述性的错误：

我已经在这里查看了类似的问题并找到了Android Emulator does not launch LibGDX project?，但是给出的解决方案并不适用于我所拥有的。还有libgdx my first triangle tutorial not working?，它指向我尝试的新教程，但没有用。

我第一次尝试按照GITHUB上的教程，以及第二次来自Scratch＆＃39; LibGDX Tutorial 1: Creating an initial project的游戏。 我尝试过不同的API级别8,13,16和＆amp; 19。

以下是日志文件的转储：

Answer 1

正如@Sid在评论中所说，错误说LibGDX需要OpenGL ES 2.0支持。模拟器的软件渲染器不支持OpenGL ES 2.0。

您可以通过在模拟器中启用图形加速来支持您的模拟器。请参阅http://developer.android.com/tools/devices/emulator.html#accel-graphics和Android OpenGL ES 2.0 emulator

以下是突出显示设置的Android Virtual Device Manager对话框。启用此功能无疑可以解决Macbook Air和许多其他计算机上的问题。

感谢。

我有三星Galaxy S-III G4，所以我刚刚安装了Kies from Samsung，这似乎涵盖了驱动程序。

我关注了HowTo Run an android application in a mobile device，LibGDX Hello-World应用程序在我的设备上运行。
