在研究有关Android游戏开发的书时，我遇到了以下日食警告：ActivityManager: Warning: Activity not started, its current task has been brought to the front
基本上，我有3个项目； Snake先生，Snake.Framework先生和Snake先生。
在我的Mr.Snake文件中，我有：

基本上，我找不到错误的根源。 ActivityManager：警告：活动尚未开始，其当前任务已被置于最前面我目前在Eclipse中使用模拟器。我试图重建我的项目，重新安装并清理它，但对我来说没有任何用。我感谢你们花时间阅读我写的这么长的帖子。
最佳答案
发生这种情况是因为新APK文件中没有任何更改，因此请在再次运行之前尝试清除代码或重新编译该代码，否则该代码将消失。
如果您尝试第二次运行该游戏，则Android操作系统将检查APK文件是否与当前文件相比有所更改。并且由于游戏已经启动，因此操作系统将不会重新打开该应用程序。他将继续已经打开的那一个。
最快的解决方案是按电子剪辑上的项目名称，然后选择清理或重建应用程序。
