Android Permissions on Runtime.getRuntime().exec()

I have an App with the following permission on the manifest. My App is running on Android JB 4.1.2.

UPDATE: I'm trying to run the App on JB, but it not works. It works on earlier API versions.

<manifest xmlns...>
   <uses-permission android:name="android.permission.SET_DEBUG_APP"/>

The problem is when I execute a command like this:

Process proc = Runtime.getRuntime().exec("service call activity 42 s16 com.android.systemui");
    BufferedReader bufferedReader = new BufferedReader(
    new InputStreamReader(proc.getInputStream()));

    String line;
    while ((line = bufferedReader.readLine()) != null) {
        Log.e("IDSPlayer", "RESULTAT BARRA:" + line);
    }

The result is as follows:

This worked perfectly on ICS devices and it needs to have SET_DEBUG_APP permission in order to run preperly. In my new device is not working even if the permission is on the manifest.

In the other hand, the command works perfectly in this new device if I execute through ADB.

How can I solve the permission issue? Could be a bug of the device?

At least in Jelly Bean, SET_DEBUG_APP cannot be held except by apps that are either signed with the firmware's signing key or are installed on the system partition. Ordinary SDK applications cannot hold this permission.
