NetworkStatsManager类 网络数据管理类 Android 6.0后推出的 提供对网络使用历史和统计数据的访问，分为Summary queries（摘要查询）和 History queries（历史查询） 根据实际场景 个人建议尽量使用Summary queries ### 2.我使用的几个api如下 #### 2.1.API方法 ``` 查询网络使用统计摘要。（查询多个应用流量统计） 会返回多个桶 需要循环遍历 在根据uid 的到每一个的实时流量 querySummary(int networkType, String subscriberId, long startTime, long endTime) 查询网络使用统计摘要。结果是整个设备的汇总数据使用情况。结果是随着时间、状态、uid、标签、计量和漫游聚合的单个存储桶 querySummaryForDevice(int networkType, String subscriberId, long startTime, long endTime) ``` #### 2.2.API方法中的参数说明 ``` 1.networkType 查询网络类型 （ConnectivityManager.TYPE_WIFI，ConnectivityManager.TYPE_MOBILE） 2.subscriberId 设备唯一id（android 10及以后设备 获取不了，可不传） 3.startTime 查询指定时间段 开始时间戳 4.endTime 查询指定时间段 结束时间戳 5.uid 查询设备的Uid 这个我用的是在方法里判断了 ``` ### 3. api方法的使用 #### 3.1.querySummaryForDevice的使用 整个设备的汇总数据使用情况 ``` /** * 获取 所有移动使用流量信息 * * @param context 上下文 * @param isDayAndMonth 是否是当天还是当月 * @return 返回 当天 还是当月的流量信息 */ public TrafficBean getAllDay_MonthMobileInfo(Context context, boolean isDayAndMonth) { TrafficBean trafficBean = new TrafficBean(); NetworkStats.Bucket bucket; try { bucket = networkStatsManager.querySummaryForDevice(ConnectivityManager.TYPE_MOBILE, getSubscriberId(context, ConnectivityManager.TYPE_MOBILE), isDayAndMonth ? getTimesmorning() : getTimesMonthmorning(), System.currentTimeMillis()); } catch (RemoteException e) { return trafficBean; } trafficBean.setRxBytes(bucket.getRxBytes()); trafficBean.setTxBytes(bucket.getTxBytes()); trafficBean.setTotalData(bucket.getTxBytes() + bucket.getRxBytes()); return trafficBean; } ``` #### 3.2.querySummary 的使用 （查询多个应用流量统计） 我使用这个是查询每一个应用的的实时流量情况 **记得使用过后 记得释放 网络统计信息 networkStats.close() 记得判空 我开始没有释放这个，报系统system 异常 但是不影响使用** ``` /** * 获取今日 或者今月的实时流量使用情况 * * @param context 上下文 * @param isDayAndMonth 是否是今天还是今月 * @return 获取今日 或者今月的流量使用情况 */ public TrafficBean getSummaryTrafficMobile(Context context, boolean isDayAndMonth) { TrafficBean trafficBean = new TrafficBean(); trafficBean.setUid(packageUid + ""); NetworkStats networkStats = null; try { networkStats = networkStatsManager.querySummary( ConnectivityManager.TYPE_MOBILE, getSubscriberId(context, ConnectivityManager.TYPE_MOBILE), isDayAndMonth ? getTimesmorning() : getTimesMonthmorning(), System.currentTimeMillis()); long mobileTraffic = 0;// long mobileRx = 0; long mobileTx = 0; NetworkStats.Bucket bucket = new NetworkStats.Bucket(); do { networkStats.getNextBucket(bucket); int summaryUid = bucket.getUid(); if (packageUid == summaryUid) { mobileTx += bucket.getTxBytes(); mobileRx += bucket.getRxBytes(); } } while (networkStats.hasNextBucket()); mobileTraffic = mobileRx + mobileTx; trafficBean.setTxBytes(mobileTx); trafficBean.setRxBytes(mobileRx); trafficBean.setTotalData(mobileTraffic); } catch (RemoteException e) { e.printStackTrace(); } finally { if (networkStats != null) { networkStats.close(); } } return trafficBean; } ``` #### 3.3完整代码NetworkStatsHelper ``` import android.annotation.SuppressLint; import android.app.usage.NetworkStats; import android.app.usage.NetworkStatsManager; import android.content.Context; import android.net.ConnectivityManager; import android.os.Build; import android.os.RemoteException; import android.telephony.TelephonyManager; import androidx.annotation.RequiresApi; import com.tjf.traffic.bean.TrafficBean; /** * @author: tjf * @date: 2022-12-10 * @desc： NetworkStatsHelper 流量查询辅助类 * *
