在做项目是遇到这个错误
google ： WindowManager: Activity has leaked window
在stackoverflow.com（链接http://stackoverflow.com/questions/2850573/activity-has-leaked-window-that-was-originally-added）中找到答案
最佳答案是 You're trying to show dialog after you're exit activity ( your thread came back ). THere are like 5 question with same thing in the last two weeks
另外一个给我帮助的回答是
看到以上回答后，我检查代码。发现在对话框中直接调用了finish方法，在finish前加了dismiss方法后，该错误解决。
