How to get Tethering and Mobile Hotspot data usage in Android using NetworkStatusManager or TrafficStat

问题

I have an Android application which displaying data usage per app by NetworkStatusManager, but I can't get data usage for Tethering and Mobile Hotspot. How should I do this?

回答1:

You need to query by UID and pass in the tethering UID: android.app.usage.NetworkStats.Bucket.UID_TETHERING like so:

networkStatsManager.queryDetailsForUid(ConnectivityManager.TYPE_MOBILE,
    subscriberId, startDate, endDate, 
    android.app.usage.NetworkStats.Bucket.UID_TETHERING);
