正如上面其他人回答的那样，“跳过55帧!”意味着应用程序中有一些繁重的处理。

对于我的情况，我的申请过程并不繁琐。我反复检查了所有内容，并删除了那些我认为有点沉重的过程。

我删除了片段、活动、库，直到只剩下骨架。但是问题仍然没有消失。我决定检查一下资源，发现我使用的一些图标和背景相当大，因为我忘记检查这些资源的大小。

因此，我的建议是，如果以上答案都没有帮助，您也可以检查您的资源文件大小。

我也有同样的问题。在我的情况下，我有2个嵌套的相对布局。RelativeLayout总是要做两个措施通过。如果你嵌套RelativeLayouts，你会得到一个指数测量算法。

在我的例子中，这是因为我不小心在一个方法上设置了一个断点。一旦我清除了它，消息就消失了，性能提高了很多。

UI线程延迟的另一个常见原因是SharedPreferences访问。当你调用PreferenceManager。getSharedPreferences和其他类似的方法，关联的.xml文件将立即在同一个线程中加载和解析。

解决这个问题的一个好方法是从后台线程触发第一次SharedPreference加载，越早越好(例如从你的Application类的onCreate开始)。这样，在您想要使用首选项对象时，首选项对象可能已经构造好了。

Unfortunately, sometimes reading a preference files is necessary during early phases of startup (e.g. in the initial Activity or even Application itself). In such cases it is still possible to avoid stalling UI by using MessageQueue.IdleHandler. Do everything else you need to perform on the main thread, then install the IdleHandler to execute code once your Activity have been fully drawn. In that Runnable you should be able to access SharedPreferences without delaying too many drawing operations and making Choreographer unhappy.

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.

还没有解决，但会解决的。对于我的小项目，有一个可组合的功能(按钮)和逻辑来检查是否“com. com”。在启动模拟器时，我在相同的日志中有以下内容:

I/Choreographer: Skipped 34 frames!  The application may be doing too much work on its main thread.
