Question

我是android的初学者，我相信我的代码都很好但是当在模拟器中加载应用程序时，应用程序崩溃并且需要强制关闭。我得到了轰鸣声logcat，我搜索了错误，但说实话我不明白，他们的其他解决方案转换为适合我的（我确实尝试过）

编辑：从我从其他线程可以看出，我可能需要在清单中添加一些内容吗？

有人可以在我的代码中用波纹管logcat向我解释我应该寻找什么，或者至少指出我可以尝试的事情吗？

如果还有其他任何我可以做的来帮助解决这个问题，那么我很不得不接受这个问题。我的项目很多都是由同样的错误造成的。

感谢您提前获得的所有帮助，这是我的第一篇文章，所以很高兴：）

由于开放1周而导致线程崩溃。

我认为这可能只是与使用Android模拟器的GLSurfaceView相关的问题。尝试使用实际设备，看看会发生什么。
