ANR (Application Not Responding) is not exactly an error.It is shown when your application is very sluggish and takes a lot of time to respond making the user wait.The user won't appreciate if your application makes him wait for a long time so the android framework gives the user an option of closing your applicaiton. http://developer.android.com/guide/practices/design/responsiveness.html

这会发生，当你正在做的主线程上长时间运行的业务和系统无法在此期间，因为主线程处理用户的交互是blocked.The解决办法是做繁重的业务工作线程，并保持主线程自由。

This occurs when you are doing long running operations on the main thread and the system can't process user interactions during this period since the main thread is blocked.The solution is to do the heavy operations in a worker thread and keep the main thread free.
