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.

我也有同样的问题。当我在另一台计算机上运行这段代码时，它工作得很好。然而，在我的系统上，它显示“应用程序可能在主线程上做了太多的工作”。

我通过重新启动Android工作室解决了我的问题[文件->无效缓存/重新启动->单击“无效并重新启动”]。

我的应用程序也有同样的问题。但除了显示卡片列表和文本之外，它并没有做其他事情。没有在后台运行。但随后经过一些调查发现，卡片背景的图像设置导致了这种情况，尽管它很小(350kb)。然后我将图像转换为9patch图像使用 http://romannurik.github.io/AndroidAssetStudio/index.html。 这对我很管用。

因为我首先最好使用SVG图像而不是所有其他类型的图像，如果不可能，使用一些图像处理工具(如Adobe Photoshop或Fotosizer)压缩所有PNG和JPG资源。最简单的方法之一是在线图像压缩工具，像这样，它帮助我把所有的图像文件减少到初始大小的50%。

我不是专家，但当我想从我的android应用程序发送数据到web服务器时，我得到了这个调试消息。虽然我使用AsyncTask类并在后台进行数据传输，但为了从服务器获取结果数据，我使用了AsyncTask类的get()方法，这使得UI同步，这意味着你的UI将等待太长时间。所以我的建议是让你的应用程序在一个单独的线程上执行每个面向网络的任务。
