I got issue with Nexus 10 - 4.2.2. I was testing code below on Galaxy Tab 10.1 with 4.0.4 and it was working fine:

try 
{
    Process proc = Runtime.getRuntime()

    To show and hide the system bar and notification bar on 4.2.2 and others:

    Hide:

        try
        {
            String command;
            command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 42 s16 com.android.systemui";
            Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
            proc.waitFor();
        }
        catch(Exception ex)
        {
            Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
        }
    

    Show:

        try 
        {
             String command;
             command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";
             Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
             proc.waitFor();
        } 
        catch (Exception e) 
        {
              e.printStackTrace();
        }
