问题描述

在android中如何在android 4.4及以上版本中开启和关闭移动数据.我已经使用过这段代码，但它在 android 4.4 及以上版本中不起作用:

In android how to enable mobile data on and off in android 4.4 and above versions. I have used this code but it is not working in android 4.4 and above versions:

private void setMobileDataEnabled(Context context, boolean enabled){
    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);
}

推荐答案

您无法在 android 4.4 以上以编程方式打开/关闭移动数据.出于安全原因，它已被停止，您可以使用对话框要求用户启用移动数据，然后如果他启用您就可以完成您的任务.

You cannot access mobile data on / off programmaticaly above android 4.4 .It have been made stopped for security reasons ,instead you can ask the user using a dialog to enable the mobile data and then if he enable you can do your task.
