android - 如何获取android中所有应用程序在给定时间段（例如上个月）使用的总移动数据的统计信息

Question

我正在尝试获取所有应用程序在上个月（或一周）或给定时间段之间使用的移动数据。我想获取移动数据使用历史记录。我看到android现在默认这样做了。是否可以通过代码获取此信息？

Answer 1

是否可以通过代码获取此信息？

至少通过 Android 4.4，没有任何记录或支持的方式。不过，欢迎您通过定期检查TrafficStats自己收集这些数据。

Answer 2

试试这个代码

public void getPakagesInfoUsingHashMap() {
    final PackageManager pm = getPackageManager();
    // get a list of installed apps.
    List<ApplicationInfo> packages = pm.getInstalledApplications(0);

    // loop through the list of installed packages and see if the selected
    // app is in the list
    for (ApplicationInfo packageInfo : packages) {
        // get the UID for the selected app
        UID = packageInfo.uid;
        String package_name = packageInfo.packageName;
        ApplicationInfo app = null;
        try {
            app = pm.getApplicationInfo(package_name, 0);
        } catch (NameNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String name = (String) pm.getApplicationLabel(app);
        Drawable icon = pm.getApplicationIcon(app);
        // internet usage for particular app(sent and received)
        double received = (double) TrafficStats.getUidRxBytes(UID)

                / (1024 * 1024);
        double send = (double) TrafficStats.getUidTxBytes(UID)
                / (1024 * 1024);
        double total = received + send;

        if(total>0)
        {
            PackageInformationTotal pi=new PackageInformationTotal();
            pi.name=name;
            pi.packageName=package_name;
            pi.icon=icon;               
            pi.totalMB=String.format( "%.2f", total )+" MB";
            pi.individual_mb=String.format( "%.2f", total );
            totalData+=Double.parseDouble(String.format( "%.2f", total ));
            dataHash.add(pi);
        Log.e(name,String.format( "%.2f", total )+" MB");
        }

    }
    Editor edit=shared.edit();
    edit.putString("Total",String.format( "%.2f", totalData));
    edit.commit();
}

您将需要实现您的代码以使用 TraficStats API 并跟踪每个 UID（应用程序）发送/接收的字节数。
