Question

输入调度超时（等待，因为没有窗口有焦点，但有一个专注的应用程序，最终可能会在完成启动时添加一个窗口。）

嗨！我从几个用户那里得到了这个奇怪的ANR报告。不幸的是，我对ANR报告的知识非常有限，我希望有人可以帮助我理解这可能是什么原因

Answer 1

在主（主）线程中发生长操作时会发生ANR。如果此线程忙，Android无法处理应用程序中的任何其他GUI事件，从而抛出ANR对话框。

显然，您的代码中有一部分耗费了大量资源或需要时间来完成。这就是让您的应用投入ANR的原因。

检查你的DNDMasterActivityNEW.java课程，有些事情会延迟你的输入调度。有几种方法可以解决这个问题：

您可以使用progressbar来指示调度何时进行，并将可见性设置为＆＃34; GONE＆＃34;什么时候完成。
使用不同的线程进行调度。
找到一种更适合时间的替代方案，替代您用来发送输入的当前方法。

如果仍然无法解决问题，请发布DNDMasterActivityNEW.java代码。
