获取移动数据的NetworkStatsManager安卓问题

Question

我正在使用6.0中的NetworkStatsManager获取移动数据，并使用此方法

 public long getAllRxBytesMobile1(Context context) {
    NetworkStats.Bucket bucket;
    try {
        bucket = networkStatsManager.querySummaryForDevice(ConnectivityManager.TYPE_MOBILE,
                getSubscriberId(context, ConnectivityManager.TYPE_MOBILE),
                0,
                System.currentTimeMillis());
    } catch (RemoteException e) {
        return -1;
    }
    return bucket.getRxBytes();
}

和

private String getSubscriberId(Context context, int networkType) {
    if (ConnectivityManager.TYPE_MOBILE == networkType) {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        return tm.getSubscriberId();
    }
    return "";
}

但总是返回零。如何解决这个问题？

试试这个：

TelephonyManager telephonyManager = (TelephonyManager) mContext
        .getSystemService(Context.TELEPHONY_SERVICE);
int slotIndex = 1;
int subscriptionId = SubscriptionManager.from(mContext).getActiveSubscriptionInfoForSimSlotIndex(slotIndex).getSubscriptionId();
try {
    Class c = Class.forName("android.telephony.TelephonyManager");
    Method m = c.getMethod("getSubscriberId", new Class[] {int.class});
    Object o = m.invoke(telephonyManager, new Object[]{subscriptionId});

    String subscriberId = (String) o;
} catch (Exception e) {
    e.printStackTrace();
}
