Android 获取应用流量的使用情况有两种方法

TrafficStats

NetworkStatsManager 是Android 6.0(API23)中新增加的类

这次我们使用的是第二种方法，记录一下实现过程

首先说明NetworkStatsManager能提供哪些功能

区分 Wifi 和手机网络的流量使用

查询指定应用的流量使用

查询指定时间段的流量使用(当天/当月/总共)

区分接收和发送的流量使用

看下方法使用代码

/**

* 本机使用的 wifi 总流量

*/

public long getAllBytesWifi() {

NetworkStats.Bucket bucket;

try {

bucket = networkStatsManager.querySummaryForDevice(ConnectivityManager.TYPE_WIFI,

"",

0,

System.currentTimeMillis());

} catch (RemoteException e) {

return -1;

}

//这里可以区分发送和接收

return bucket.getTxBytes() +bucket.getRxBytes() ;

}

/**

* 本机使用的 mobile 总流量

*/

public long getAllBytesMobile() {

NetworkStats.Bucket bucket;

try {

bucket = networkStatsManager.querySummaryForDevice(ConnectivityManager.TYPE_MOBILE,

getSubscriberId(context, ConnectivityManager.TYPE_MOBILE),

0,

System.currentTimeMillis());

} catch (RemoteException e) {

return -1;

}

//这里可以区分发送和接收

return bucket.getTxBytes() +bucket.getRxBytes() ;

}

private String getSubscriberId(Context context, int networkType) {

if (ConnectivityManager.TYPE_MOBILE == networkType) {

TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

return tm.getSubscriberId();

}

return "";

}

/**

* 获取指定应用 wifi 发送的当天总流量

* @param packageUid 应用的uid

* @return

*/

public long getPackageTxDayBytesWifi(int packageUid) {

NetworkStats networkStats = null;

try {

networkStats = networkStatsManager.queryDetailsForUid(

ConnectivityManager.TYPE_WIFI,

"",

getTimesmorning(),

System.currentTimeMillis(),

packageUid);

} catch (RemoteException e) {

return -1;

}

NetworkStats.Bucket bucket = new NetworkStats.Bucket();

networkStats.getNextBucket(bucket);

return bucket.getTxBytes();

}

/**

* 获取当天的零点时间

*

* @return

*/

public static long getTimesmorning() {

Calendar cal = Calendar.getInstance();

cal.set(Calendar.HOUR_OF_DAY, 0);

cal.set(Calendar.SECOND, 0);

cal.set(Calendar.MINUTE, 0);

cal.set(Calendar.MILLISECOND, 0);

return (cal.getTimeInMillis());

}

//获得本月第一天0点时间

public static int getTimesMonthmorning() {

Calendar cal = Calendar.getInstance();

cal.set(cal.get(Calendar.YEAR), cal.get(Calendar.MONDAY), cal.get(Calendar.DAY_OF_MONTH), 0, 0, 0);

cal.set(Calendar.DAY_OF_MONTH, cal.getActualMinimum(Calendar.DAY_OF_MONTH));

return (int) (cal.getTimeInMillis());

}

/**

* 根据包名获取uid

* @param context 上下文

* @param packageName 包名

*/

public static int getUidByPackageName(Context context, String packageName) {

int uid = -1;

PackageManager packageManager = context.getPackageManager();

try {

PackageInfo packageInfo = packageManager.getPackageInfo(packageName, PackageManager.GET_META_DATA);

uid = packageInfo.applicationInfo.uid;

} catch (PackageManager.NameNotFoundException e) {

e.printStackTrace();

}

return uid;

}

调用过程

//以上的方法封装在了NetworkStatsHelper类里

public class NetworkStatsHelper {

NetworkStatsManager networkStatsManager;

int packageUid;

public NetworkStatsHelper(NetworkStatsManager networkStatsManager) {

this.networkStatsManager = networkStatsManager;

}

}

//初始化这个工具类

NetworkStatsManager networkStatsManager = (NetworkStatsManager) getSystemService(NETWORK_STATS_SERVICE);

helper = new NetworkStatsHelper(networkStatsManager);

循环遍历应用

PackageManager packageManager = getPackageManager();

final List applicationInfoList = packageManager.getInstalledPackages(0);

for (PackageInfo info : applicationInfoList) {

try {

PackageInfo pack = packageManager.getPackageInfo(info.packageName,PackageManager.GET_PERMISSIONS);

String[] requestedPermissions = pack.requestedPermissions;

if (requestedPermissions == null)

continue;

if (info.applicationInfo.uid == 1000)

continue;

for (String str : requestedPermissions) {

if (str.equals("android.permission.INTERNET")) {

long mobileTodayRx = helper.getPackageDayRxBytesMobile(mContext, uid);

//...添加自己的代码

break;

}

}

} catch (PackageManager.NameNotFoundException exception) {

exception.printStackTrace();

}

}

这里说明下为什么要过滤掉info.applicationInfo.uid == 1000

因为没有获取uid == 1000的进程的流量权限

好了现在说到权限，下面就是需要配置的权限

其中tools:ignore 就是忽略这个错误的意思，不然它会报红

仅仅在manifest里配置权限还是不够的，还要动态申请

private boolean hasPermissionToReadNetworkStats() {

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);

if (permissionCheck != PackageManager.PERMISSION_GRANTED) {

ActivityCompat.requestPermissions(this,

new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);

} else {

}

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {

return true;

}

final AppOpsManager appOps = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);

int mode = appOps.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS,

android.os.Process.myUid(), getPackageName());

if (mode == AppOpsManager.MODE_ALLOWED) {

return true;

}

requestReadNetworkStats();

return false;

}

// 打开“有权查看使用情况的应用”页面

private void requestReadNetworkStats() {

Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);

startActivity(intent);

}

OK，到此就应该能成功获取流量统计信息了
