我用While（真的）操纵了它，它工作得很好，
从启动服务的日志中，尝试共享其他代码详细信息。是否将活动绑定到服务？ 如果是这样，请确保只绑定一次。 如果您多次绑定到它，它在完成其工作时不会停止，这可能会导致您的ANR：
请参阅：我的是一个IntentService，我通过AlarmManger作为PendingEvent启动它。我一点也不绑定。不是真的，我在onHandleIntent之后创建了一个线程。我已将stacktrace附加到我的帖子中。是否您的线程正在访问相同的对象？或者您正试图在非UI工作线程上执行UI操作？是的，我的线程可能访问相同的对象。但这有关系吗？我以为我们只能访问UI对象。我们也不会用同步锁定任何对象。不仅仅是UI。。。例如，如果您正在访问和修改一个数组，该怎么办？在这种情况下，你需要保护那个物体
