我想使用traceview在其上运行Android应用程序的一些分析。我曾经包裹，我想跟踪与以下行code：

I am trying to use traceview to run some profiling against an Android application. I have wrapped the code that I want to trace with the following lines:

Debug.startMethodTracing("xxx");
// code
Debug.stopMethodTracing();

它成功地生成一个跟踪文件，我从SD卡使用下面的命令行拉：

It successfully generated a trace file, that I pulled from sdcard using the following command line:

./亚行拉/sdcard/xxx.trace

./adb pull /sdcard/xxx.trace

然而 traceview 是这样的：

./ traceview /.../ xxx.trace

./traceview /.../xxx.trace

我收到以下错误消息：

用法：JAVA   com.android.traceview.MainWindow [-r]   跟踪-r回归仅

Usage: java com.android.traceview.MainWindow [-r] trace -r regression only

我不明白此错误消息，我没有发现任何有用的谷歌。

I cannot understand this error message and I didn't find anything useful on Google.

任何帮助将是非常美联社preciated。

Any help would be much appreciated.

谢谢！

推荐答案

请确保您导入Debug类是这个： android.os.Debug

make sure that Debug class you imported is this one : android.os.Debug

或做到这一点：

android.os.Debug.startMethodTracing("xxx");
android.os.Debug.stopMethodTracing();
