将Logcat从Android应用程序保存到txt文件

Question

我想把我看到的所有logcat Android Studio(比如这里http://i.imgur.com/IJkGcL4.png)都txt file直接保存在我的设备上.

到目前为止我尝试过的是以下代码onCreate:

File logFile = new File(LogcatDir.getAbsolutePath() + "/log.txt" );
try
{
    Process process = Runtime.getRuntime().exec( "logcat -c");
    process = Runtime.getRuntime().exec( "logcat -f " + logFile + " *:S MyActivity_BUT_WHAT_TO_PUT_HERE");
}
catch ( IOException e ) {e.printStackTrace();}

并在manifest file:

<uses-permission android:name="android.permission.READ_LOGS" />

我故意做了解析错误之类的

long test = Long.parseLong("z");

但实际上只有这个log.txt:

--------- beginning of /dev/log/main
--------- beginning of /dev/log/system

有谁知道,我有什么代码,我得到整个logcat？

这对我有用,它使用以下代码将其保存在主存储器中:

        Log.w("before","Logcat save");
      // File logFile = new File( + "/log.txt" );
        try {
            Process process = Runtime.getRuntime().exec("logcat -d");
            process = Runtime.getRuntime().exec( "logcat -f " + "/storage/emulated/0/"+"Logging.txt");
        }catch(Exception e)
        {
            e.printStackTrace();
        }
