Android的跟踪文件创建，但零字节长 [英] Android trace file created but zero bytes long

问题描述

我试图遵循这个网页的指示来创建一个跟踪文件。我可以看到在文件浏览器文件中的DDMS，可以把它到我的电脑，但它是零字节长。

I am trying to follow the instructions on this page to create a trace file. I can see the file in File Explorer in DDMS and can pull it onto my PC but it is zero bytes long.

任何建议，我可能是做错了，好吗？

Any suggestions as to what I might be doing wrong, please?

推荐答案

这个问题似乎一直是我已经把在的onDestroy（）方法（如建议在开发指南）没有停止，即使我曾试图结束活动的三种不同的方式跟踪...旋转屏幕，pressing Home键，并使用Taskiller杀应用程序。

The problem seems to have been that the stopMethodTracing() call which I had put in the onDestroy() method (as suggested in the Dev Guide) failed to stop the tracing even though I had tried three different means of ending the activity ... rotating the screen, pressing the Home Key and using Taskiller to kill the app.

通过移动stopMethodTracing（）在其他地方我现在有一个数据一丝呢！

By moving the stopMethodTracing() elsewhere I now have a trace with data in it!

（重要线索是，我注意到，在LogCat中TRACE报告开始，但从来没有报道TRACE打断）。

(The vital clue was that I noticed that LogCat was reporting TRACE STARTED but never reported TRACE STOPPED.)
