1. java.lang.RuntimeException: Handler (com.***.behavior.BEvent$1) {421bca80} sending message to a Handler on a dead thread

它告诉你,你往死了的进程发了一个消息,然后没有办法执行。

我的代码错在这里:

  1. sHandler.post(runnable);

handler虽然不为空,(静态的),但是它所在的进程已经死了(推出了程序),所以你post 就会出现上面的警告。我们看下post源码:

  1. /**
  2. * Causes the Runnable r to be added to the message queue.
  3. * The runnable will be run on the thread to which this handler is
  4. * attached.
  5. *
  6. * @param r The Runnable that will be executed.
  7. *
  8. * @return Returns true if the Runnable was successfully placed in to the
  9. * message queue. Returns false on failure, usually because the
  10. * looper processing the message queue is exiting.
  11. */
  12. public final boolean post(Runnable r)
  13. {
  14. return sendMessageDelayed(getPostMessage(r), 0);
  15. }

The runnable will be run on the thread to which this handler is

* attached.

所以 进程死了,就没有办法运行了。

总结:

1.代码没执行,记得看logcat的警告。

logcat的error,会直接crash.

warn 代码没执行,或者其他的问题,都会warn.

2.android程序退出了,但是进程没有杀死。

所有的静态变量,暂时还保存着。
