Android 应用程序可能在主线程中做了太多的工作？,android,android-intent,android-activity,Android,Android Intent,Android Activity,我一直有一个问题，我的食谱书应用程序，它说我做了太多的工作，在主线程。我已附上我的代码。有人能告诉我为什么会这样吗？？我以前从未收到过，其他帖子也没用。如果有人有答案，你能详细解释一下吗？？我是新来的。我需要你向我解释这件事，就像我5岁一样，尽可能地屈尊 package com.example.recipebook; import com.example.recipebook.util.SystemUiHider; import android.view.View; import andro

这是因为android的编舞没有获得执行正确显示所需的资源，因此跳过了帧

这主要发生在用户在主线程中执行繁重的操作时，记住Android是单线程系统，有一个主线程，所有其他子系统都在该线程上执行任务，例如活动、服务、内容提供者。这就是为什么当您直接在主服务器上执行网络操作时，会收到应用程序未响应的消息

要详细说明您的情况，请执行以下操作

若你们有任何网络操作是在主线程中完成的，那个么将它们移动到一个单独的线程中，在Android native中我们有AsyncTask，尝试在Phonegap中查找线程机制

如果您有任何繁重的操作，如位图压缩等，请通过线程或后期可运行逻辑有效地处理它们，这将确保您的主线程可以自由执行琐碎的任务，如生成事件的显示处理等

从这个意义上说，任何可能需要一些时间的逻辑，将其移动到线程，这将确保您的显示运行平稳

希望能有所帮助。

您发布的任何代码都不应导致此问题。您在何处/何时看到此错误？03-09 14:34:51.909 372-387/system_process I/Choreographer﹕ 跳过98帧！应用程序可能在其主线程上做了太多工作。03-09 14:34:56.629 528-528/com.android.launcher I/编舞﹕ 跳过47帧！应用程序可能在其主线程上做了太多工作。如果你的应用程序退出，你应该在logcat中看到stacktrace。你没发那个。如果您没有看到，请检查您是否没有安装logcat，因为您可能会错过一些重要的内容。此外，如果您在单击启动另一个活动的按钮时遇到这些错误，则应检查该活动是否已实际启动（在activty中添加日志记录），并在
onCreate（）
中检查您可能正在执行的操作，
onStart（）
和
onResume（）
，所有这些都将在您启动另一个活动时调用。
