这其实不是问题。当调试器运行了很长时间时，就会发生这种情况。取下制动点并再次检查。

首先阅读警告。它表示在主线程上有更多的负载。所以你要做的就是在线程中运行有更多工作的函数。

Android UI:修复跳过的帧

任何开始开发android应用程序的人都会看到这条消息 “编舞(abc):跳过xx帧!申请可以是 在主线上做了太多工作。”那么它实际上是什么 意思是，你为什么要担心以及如何解决它。

这意味着您的代码需要很长时间来处理和帧 都因为它而被跳过，这可能是因为一些沉重的 您在应用程序或数据库的核心所做的处理 访问或任何其他事情，导致线程停止一段时间。

Here is a more detailed explanation: Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance. Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance. Since Choreographer is told about every vsync events, I can tell if one of the Runnables passed along by the Choreographer.post* apis doesnt finish in one frame’s time, causing frames to be skipped. In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens. The message “The application may be doing too much work on its main thread.” could be misleading. source : Meaning of Choreographer messages in Logcat Why you should be concerned When this message pops up on android emulator and the number of frames skipped are fairly small (<100) then you can take a safe bet of the emulator being slow – which happens almost all the times. But if the number of frames skipped and large and in the order of 300+ then there can be some serious trouble with your code. Android devices come in a vast array of hardware unlike ios and windows devices. The RAM and CPU varies and if you want a reasonable performance and user experience on all the devices then you need to fix this thing. When frames are skipped the UI is slow and laggy, which is not a desirable user experience. How to fix it Fixing this requires identifying nodes where there is or possibly can happen long duration of processing. The best way is to do all the processing no matter how small or big in a thread separate from main UI thread. So be it accessing data form SQLite Database or doing some hardcore maths or simply sorting an array – Do it in a different thread Now there is a catch here, You will create a new Thread for doing these operations and when you run your application, it will crash saying “Only the original thread that created a view hierarchy can touch its views“. You need to know this fact that UI in android can be changed by the main thread or the UI thread only. Any other thread which attempts to do so, fails and crashes with this error. What you need to do is create a new Runnable inside runOnUiThread and inside this runnable you should do all the operations involving the UI. Find an example here. So we have Thread and Runnable for processing data out of main Thread, what else? There is AsyncTask in android which enables doing long time processes on the UI thread. This is the most useful when you applications are data driven or web api driven or use complex UI’s like those build using Canvas. The power of AsyncTask is that is allows doing things in background and once you are done doing the processing, you can simply do the required actions on UI without causing any lagging effect. This is possible because the AsyncTask derives itself from Activity’s UI thread – all the operations you do on UI via AsyncTask are done is a different thread from the main UI thread, No hindrance to user interaction. So this is what you need to know for making smooth android applications and as far I know every beginner gets this message on his console.

this usually happens when you are executing huge processes in main thread. it's OK to skip frames less than 200. but if you have more than 200 skipped frames, it can slow down your application UI thread. what you can do is to do these processes in a new thread called worker thread and after that, when you want to access and do something with UI thread(ex: do something with views, findView etc...) you can use handler or runOnUiThread(I like this more) in order to display the processing results. this absolutely solves the problem. using worker threads are very useful or even must be used when it comes to this cases.

如果在应用程序中使用async/await功能，这是正常的。

在这个问题上做了很多研究之后，我得到了解决方案，

在我的情况下，我使用的服务将运行每2秒和runonUIThread，我想知道问题是在那里，但根本没有。 我发现的下一个问题是我在五月的应用程序中使用大图像，这就是问题所在。

我删除了图像，并设置了新的图像。

结论:-检查你的代码是否有任何你正在使用的原始文件是大的。
