Android9移动数据开关开启关闭方法

本文奉上一个Android移动数据开关开启关闭方法，闲话少说，直接上代码。

   public static void setDataEnabled(int slotIdx, boolean enable,Context context) throws Exception
   {
       try {
           int subid = SubscriptionManager.from(context).getActiveSubscriptionInfoForSimSlotIndex(slotIdx).getSubscriptionId();
           TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
           Method setDataEnabled = telephonyService.getClass().getDeclaredMethod("setDataEnabled", int.class, boolean.class);
           if (null != setDataEnabled) {
               setDataEnabled.invoke(telephonyService, subid, enable);
               LogUtil.LOGD(TAG,"setDataEnabled suc",false);
           }
       }catch (Exception e)
       {
           e.printStackTrace();
           LogUtil.LOGD(TAG,"setDataEnabled exception",false);
       }
   }
    
   public static boolean getDataEnabled(int slotIdx,Context context) throws Exception
   {
       boolean enabled = false;
       try {
           int subid = SubscriptionManager.from(context).getActiveSubscriptionInfoForSimSlotIndex(slotIdx).getSubscriptionId();
           TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
           Method getDataEnabled = telephonyService.getClass().getDeclaredMethod("getDataEnabled", int.class);
           if (null != getDataEnabled) {
               enabled =  (Boolean) getDataEnabled.invoke(telephonyService, subid);
           }
       }catch (Exception e)
       {
           e.printStackTrace();
       }
    
       return enabled;
   }

另外，控制移动数据开关需要一个系统权限

<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"></uses-permission>

获取这个系统权限需要app为系统应用，把app放在/system/priv-app或者对app进行系统签名均可获得系统权限。
