Read the system log on Android 4.1

Now , I want to read the system log on android 4.1 . But just can only get the application itself log . My code as following:

Process logcatProc = Runtime.getRuntime().exec(new String[] { "logcat","ActivityManager:V","*:S" });
reader = new BufferedReader(new InputStreamReader(logcatProc.getInputStream()));  
String line;
while ((line = reader.readLine()) != null) {
    Log.e("log",line);
}

it Seems can work on android 4.0 or previous version. anybody have tried this ? Or i need the root permission ?

System logs changed in 4.1 and are now accessible only by system apps. (Source: Google I/O Video.) This is an exception on rooted devices, of course, if the installed app is set to be a system app.

Aside from this, there is no way to access the system logs on Android 4.1+. Note: End users can access the system log by using the (very finicky) shortcut of Power + Vol Up + Vol Down.
