How to enable/disable Mobile Data on Android 2.3

Today, colleague asked me whether i know how to enable and disable mobile internet on Android ? Actually, I was curious about this for sometime and never had the time to look into how to do this. So this is how to do it.

I tired it on Android 2.3 i tried this code and it worked! When I looked into Android source code I saw this method is available 2.2 R1 up.

  private boolean getMobileDataEnabled() {
        try {
            Method method = connectivityManager.getClass().getMethod("getMobileDataEnabled");
            return (Boolean)method.invoke(connectivityManager);
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }
    private void setMobileDataEnabled(boolean on) {
        try {
            Method method = connectivityManager.getClass().getMethod("setMobileDataEnabled",
                    boolean.class);
            method.invoke(connectivityManager, on);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

If you are using 2.2 R1 or later try this code.
