我也有同样的问题。 我的是一个案例，我使用的背景图像是在绘图。这个特殊的图像大约有130kB，在我的android应用程序的启动画面和主页上使用。

解决方案-我只是把特定的图像从drawables转移到drawables-xxx文件夹，并且能够释放大量的内存占用在背景和跳绳帧不再跳绳。

更新使用“nodp”可绘制资源文件夹来存储背景可绘制图 文件。 密度限定的可绘制文件夹还是drawable-nodpi优先?

尝试使用以下策略来提高应用程序的性能:

尽可能使用多线程编程。即使你的智能手机只有一个核(如果处理器有两个或更多核，线程可以在不同的核上运行)，性能上的好处也是巨大的。让你的应用逻辑与UI分离是很有用的。使用Java线程，AsyncTask或IntentService。检查这个。 阅读并遵循Android开发网站的各种性能提示。检查在这里。

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.

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%。
