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
