java - libgdx android 启动失败

Question

这是我第一次使用 libgdx，我想尝试安装 gdx-setup-ui 后提供的默认应用程序。当我点击 eclipse 上的运行按钮时它运行良好，如它所示

[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...
[2014-05-01 21:40:16 - my-gdx-game-android] Success!
[2014-05-01 21:40:16 - my-gdx-game-android] Starting activity com.me.mygdxgame.MainActivity on device emulator-5554
[2014-05-01 21:40:16 - my-gdx-game-android] ActivityManager: WARNING: linker: libdvm.so has text relocations. This is wasting memory and is a security risk. Please fix.
[2014-05-01 21:40:16 - my-gdx-game-android] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.me.mygdxgame/.MainActivity }

但不幸的是，在模拟器上它说，我的 LibGDX 游戏已停止。

这些显示在 logCat 中:

另外，我删除了 MainActivity.java 中的 cfg.useGL20 = true; 行，因为它一直给我错误，我试图快速修复它，它不起作用。我真的需要它在模拟器中使用，因为我不拥有 android 设备。

Answer 1

我能够通过以下方式在 Macbook Air 上完成这项工作:

1. 打开 Android 虚拟设备管理器(例如，在 Eclipse 中，它位于“窗口”菜单下)
2. 点击您要使用的设备的“编辑”
3. 在出现的对话框中选中“使用主机 GPU”框，如图所示

保存并重试。

我猜这取决于你的电脑显卡是否支持 OpenGL2.0，但我也怀疑这在现在很普遍。
