How can I find the data usage on a per-application basis on Android?

Solution 1:

The following links should help you figure out how to programmatically determine the data usage per application.

• Create a network monitor using Android's TrafficStats class

• Android Traffic Statistics Inside

You will need to implement your code to use the TraficStats API and track the number of bytes sent/received per UID (application).

Solution 2:

Use this method after create a new class PackageInformationTotal.

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();
}

After that you can track all process usages in MB.

Solution 3:

Prorammatically:

You can declare the intent filter for the ACTION_MANAGE_NETWORK_USAGE action (introduced in Android 4.0) to indicate that your application defines an activity that offers options to control data usage. ACTION_MANAGE_NETWORK_USAGE shows settings for managing the network data usage of a specific application. When your app has a settings activity that allows users to control network usage, you should declare this intent filter for that activity. Check this out for more information about managing data usage manage usage per application.

The proper definition of ACTION_MANAGE_NETWORK_USAGE is you can see here.
