How can I turn off/on 3G/4G/Data programmatically on Android 5.0?

private void setMobileDataEnabled(Context context, boolean enabled) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
	    final ConnectivityManager conman = (ConnectivityManager)  context.getSystemService(Context.CONNECTIVITY_SERVICE);
	    final Class<?> conmanClass = Class.forName(conman.getClass().getName());
	    final java.lang.reflect.Field connectivityManagerField = conmanClass.getDeclaredField("mService");
	    connectivityManagerField.setAccessible(true);
	    final Object connectivityManager = connectivityManagerField.get(conman);
	    final Class<?> connectivityManagerClass =  Class.forName(connectivityManager.getClass().getName());
	    final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
	    setMobileDataEnabledMethod.setAccessible(true);

	    setMobileDataEnabledMethod.invoke(connectivityManager, enabled);
	}
