Libgdx在安卓上启动失败。

Question

这是我第一次使用libgdx，我想尝试安装完成后提供的默认应用程序gdx-setup-ui。当我在Eclipse上点击运行按钮时，它能够正常运行。

[2014-05-01 21:40:14 - my-gdx-game-android] Uploading my-gdx-game-android.apk onto device 'emulator-5554'
[2014-05-01 21:40:15 - my-gdx-game-android] Installing my-gdx-game-android.apk...

但在模拟器上，它显示了“不幸的是，我的 LibGDX 游戏已停止。”

这些信息显示在 logCat 中：

此外，我已删除MainActivity.java中的一行代码cfg.useGL20 = true;，因为它一直给我报错，而我尝试了快速修复它，但并没有成功��我真的需要在模拟器上使用它，因为我没有安卓设备。

我认为Android模拟器不支持OpenGL ES 2.0，而且自LibGDX 1.0版本以来也不支持< OpenGL ES 2.0，因此你应该在设备或Genymotion上进行测试。如果你在模拟器上运行，我发现这篇文章可能对你有用：ANDROID EMULATOR NOW SUPPORTS NATIVE OPENGL ES2.0! - Phonbopit

可能是LibGDX Hello-World Project does not work的重复问题。 - P.T.

哇！Genymotion对我来说运行得很好啊！谢谢回复:D - SourCreamOnion

Answer 1

我能够通过以下方式在Macbook Air上实现这个功能：

1. 打开Android虚拟设备管理器（例如，在Eclipse中，这在“Window”菜单下）
2. 点击要使用的设备的“编辑”按钮
3. 在结果对话框中勾选“使用主机GPU”，如图所示

保存并重试。

我猜这取决于您的计算机图形卡是否支持OpenGL2.0，但我也怀疑这在今天是相当普遍的。
