I'm trying to redirect the log of my app to the sdcard file. But i failed to do so. I'm trying something like this.

String cmd= "logcat -v time   ActivityManager:W  myapp:D  *:* >\""+file.getAbsolutePath()+"\"";
Runtime.getRuntime().exec(cmd);

I tried the -f option also but it is not working either.

This is my worked version:

try {
    File filename = new File(Environment.getExternalStorageDirectory()+"/logfile.log"); 
    filename.createNewFile(); 
    String cmd = "logcat -d -f "+filename.getAbsolutePath();
    Runtime.getRuntime().exec(cmd);
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

find your logfile /sdcard/logfile.log
