我在启动画面中显示fade three images动画。我的输出成功了。
但我得到了two issue：
时间加载：
应用不关闭：
进入Application.I我试图在模拟器中的后退按钮的帮助下关闭这些应用程序。但它永远不会关闭一个 应用
它停留在一个应用程序本身。在日志猫中，我看到循环1,2和3一次又一次地继续。我无法关闭我的应用程序。
如果我按下主页按钮，它会显示主屏幕，但会再次自动进入应用程序。
logcat的：
我没有得到任何logcat错误。但是你可以看到logcat读数总是在运行。它永远不会停止。循环1,2和3连续读取logcat。对于这些它永远不会关闭一个应用程序。然后如果我是按主页按钮，将显示主屏幕。但有时它会自动进入这些应用程序。
