Question

我正在关注this教程，使用libGDX学习安卓游戏编程。按照说明，我已经能够在eclipse中为桌面和Android应用程序创建一个项目。我的桌面应用程序运行没有任何故障。但是我的android应用程序没有在模拟器上运行。我使用API 21来创建项目和模拟器。我正在使用java 1.7.0_79和eclipse火星。每次我运行该程序时，都会弹出“不幸的是，my-gdx-game已停止”错误。

在搜索stackoverflow之后，我看到了以下建议：

确保模拟器已勾选“使用主机GPU”。我做到了这一点。
确保android项目属性具有相同的API。我也这样做了。

运行应用程序时，我的模拟器屏幕如下所示。有一个？在目标列上标记。为什么会这样？这会导致问题吗？

我的logcat显示了这一点。

我错过了什么吗？有什么建议？

使用libGDX和eclipse获取“不幸的是，my-gdx-game已停止”错误
