本文介绍了一种通过编程方式禁用或启用Android设备上移动数据的方法。该方法利用了反射机制来调用系统的内部接口，实现了对移动数据开关状态的控制。

private void setMobileDataEnabled(Context context, boolean enabled)
			throws ClassNotFoundException, SecurityException,
			NoSuchFieldException, IllegalArgumentException,
			IllegalAccessException, NoSuchMethodException,
			InvocationTargetException {
		final ConnectivityManager conman = (ConnectivityManager) context
				.getSystemService(Context.CONNECTIVITY_SERVICE);
		final Class conmanClass = Class.forName(conman.getClass().getName());
		final Field iConnectivityManagerField = conmanClass
				.getDeclaredField("mService");
		iConnectivityManagerField.setAccessible(true);
		final Object iConnectivityManager = iConnectivityManagerField
				.get(conman);
		final Class iConnectivityManagerClass = Class
				.forName(iConnectivityManager.getClass().getName());
		final Method setMobileDataEnabledMethod = iConnectivityManagerClass
				.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
		setMobileDataEnabledMethod.setAccessible(true);

		setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
	}
