在装有 Android 4.4 的手机上发现了该问题。在许多其他情况下，在其他操作系统版本上，该方法可以正常工作。
【问题讨论】：
可能位图对于手机来说太大了？ 在 4.4 上读取文件存在问题这一事实让我想知道是否是 SD 卡更改的问题。 我该如何解决这个问题？也许我可以插入一个 try-catch 来控制它？ 我想弄清楚为什么在线程暂停时它正在打印堆栈跟踪。它的一部分是否显示在日志中？ 一位正在使用我的应用程序的用户向我发送了此崩溃报告.. 【参考方案1】：对于仍然遇到此类错误的任何人，这是我的结论：
经过大量搜索并尝试了我在网络上可以找到的所有内容后，我自己修复了它。我用DDMS查看了我设备上当前正在运行的线程，发现有一个ASyncTask运行了很长时间，从未停止过。
似乎它正在访问主线程正在访问的“某物”，在访问该“某物”一段时间后，两个线程发生碰撞，导致应用程序挂起，导致 ANR em> 例外。
我所做的是删除 ASyncTask，而是在应用程序启动时（启动时）执行此“一次性”操作，以确保它只会运行一次且不再运行。
我真的建议使用 DDMS 来查看当前线程，因为 ANR 通常是由同步/并发问题引起的。 p>
如果您收到此错误，请随时与我私下联系。
【讨论】：
我也遇到了同样的错误，你怎么知道哪个进程正在进行很长时间以及如何找到哪个类，因为在我的情况下我没有使用任何@987654321 @ 在那个特定的类中 @George Cloone-y 你能否详细说明一下你是如何解决这个问题的，或者可以分享你的联系方式以便我们进行简短的讨论？以上是关于Android 4.4 上的 ANR 输入调度超时的主要内容，如果未能解决你的问题，请参考以下文章
com.android.inputmethod.latin 中的 ANR 原因：输入调度超时
