How do I programmatically show data usage of all applications?

问题

On Android 4.0 onwards we have data usage control options in the phone. Please check the attached screen shot for further understanding.

http://developer.android.com/about/versions/android-4.0-highlights.html

Now I have some requirement to check these things (All Application's Data usage in specific time period/specific days) from my application. How can I achieve this? I am also using the below class for Network Usage details.

Please check the below link images. I need to develop the same kind of application.

Thanks for sharing your code, but I need to know data used by each application instead of all applications. So far I observed in the links no one is talking about data usage of individual applications. I already know how to show installed applications in the device. Now I would like to know what's the data used by each and every application.

I am using the below code for list of installed applications in the device.

private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
    ArrayList<PInfo> res = new ArrayList<PInfo>();

    List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);

    for (int i=0; i<packs.size(); i++) {
        PackageInfo p = packs.get(i);
        if ((!getSysPackages) && (p.versionName == null)) {
            continue ;
        }
        PInfo newInfo = new PInfo();
        newInfo.setAppname(p.applicationInfo.loadLabel(getPackageManager()).toString());
        newInfo.setPname(p.packageName);
        newInfo.setVersionName(p.versionName);
        newInfo.setVersionCode(p.versionCode);
        newInfo.setIcon(p.applicationInfo.loadIcon(getPackageManager()));

        res.add(newInfo);
    }
    return res;
}

How do I know what's the data used by each application?

Actually, I need a solution which gives data usage of applications in a given time period, i.e. in between two days.

First, get a list of all running apps' process info:

List<RunningAppProcessInfo>

Then get the UID of every app and get then send and receive traffic of the app:

// Get running processes
ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<RunningAppProcessInfo> runningApps = manager.getRunningAppProcesses();

for (RunningAppProcessInfo runningApp : runningApps) {

  // Get UID of the selected process
  int uid = ((RunningAppProcessInfo)getListAdapter().getItem(position)).uid;

  // Get traffic data
  long received = TrafficStats.getUidRxBytes(uid);
  long send   = TrafficStats.getUidTxBytes(uid);
  Log.v("" + uid , "Send :" + send + ", Received :" + received);
}

You can use the android.net.TrafficStats for getting the network usage details.

Please find a sample program below for the same.

package com.anchit.trafficstatus;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;

public class TrafficStatus extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Log.e("bytes recvd", "" + android.net.TrafficStats.getMobileRxBytes());

        Log.e("Total", "Bytes received" + android.net.TrafficStats.getTotalRxBytes());
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

The solution from Arunendra, dated 2015, didn't immediately work for me on SDK 28 (Pie).

So I modified as follows:

void networkUsage() {
    // Get running processes
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningAppProcessInfo> runningApps = manager.getRunningAppProcesses();
    for (ActivityManager.RunningAppProcessInfo runningApp : runningApps) {
        long received = TrafficStats.getUidRxBytes(runningApp.uid);
        long sent = TrafficStats.getUidTxBytes(runningApp.uid);
        Log.d(LOG_TAG, String.format(Locale.getDefault(), 
                "uid: %1d - name: %s: Sent = %1d, Rcvd = %1d", runningApp.uid, runningApp.processName, sent, received));
    }
}
