android - 游戏在不同时间强制关闭。需要帮助解释 logCat 警告和错误

Question

我的游戏以启动画面开始并播放音乐，直到有人触摸屏幕或给定的时间到期。然后它转到有两个按钮的菜单 Activity ，一个用于开始游戏，另一个用于打开一个关于 Activity ，弹出一个透明窗口告诉用户有关游戏的信息。

我目前的问题是，有时当我开始游戏时，我会立即强制关闭，或者当我触摸屏幕以跳过飞溅时，当我按下开始玩游戏时，甚至在这种错误的特定情况下我按下了关于按钮。对我来说奇怪的是有时一切正常。

即使它有效，我也遇到了很多这样的错误，我只需要一些帮助来解释它们，这样我就可以修复它们。我不确定我是从什么时候开始关闭这些力的，因为它之前一直在工作。虽然我总是有错误，但我不想要不稳定的东西。

如果您需要其他信息来提供帮助，您知道我在哪里。 :D

谢谢，我迫不及待地想让这个应用程序回到正轨，这样我就可以处理功能了!!

以下错误是运行我的游戏并在主菜单中按下并强制关闭的结果。

Answer 1

从这里开始:

ERROR/MediaPlayer(302): stop called in state 1

MediaPlayer 希望它的方法以特定的顺序被调用。见状态图:http://developer.android.com/reference/android/media/MediaPlayer.html

您似乎是在 idle (1) 状态下调用它:http://androidxref.com/2.2.3/xref/frameworks/base/include/media/mediaplayer.h#111
