您必须确保正在处理所有引发的异常.这就是导致强制关闭(未捕获的异常)的原因.至于不响应"消息，同样，这取决于开发人员.您需要产生新线程并执行异步任务，这样处理不会阻塞主线程，而主线程正是UI运行的对象.当主线程被阻塞时，即发生无响应"消息.如果生成新线程，则可以向用户显示您想要的哪种消息，以通知用户正在处理某些事情.

You have to make sure you are handling any exceptions that are thrown. That is what causes a force close, an uncaught exception. as for the "not responding" message, again, this is up to the developer. You need to spawn new threads and do async tasks, that way processing does not block the main thread, which is what the UI runs on. When the main thread is blocked, that is when the "not responding" message happens. If you spawn a new thread, then you can display what ever kind of message you want to the user to notify them that something is processing.
