As other people say use the command "pm disable com.android.systemui" in root mode, so the following code execute this command in your android app, just call the following method, your tablet needs to be rooted.

private void hideNavigationBar(){
        try {
            Process process = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(process.getOutputStream());
            os.writeBytes("pm disable com.android.systemui\n");
            os.flush();
            os.writeBytes("exit\n");
            os.flush();
            process.waitFor();
            //////////////////////////////////////
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

This code hide the navigation bar on the android system, to reappear system bar use "pm enable com.android.systemui" instead of "pm disable com.android.systemui" in the previous code.
