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

Question

I am trying to find out the data usage on Android on a per-application basis. Something like Android Data Usage Apps and Quota / Cap Monitor Widgets: never get charged extra for data or get capped again!.

I looked at Stack Overflow question How to go about detecting data usage in the Android environment.

But it's not been of much help.

ActivityManager activityManager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE); ActivityManager.MemoryInfo mInfo = new ActivityManager.MemoryInfo(); activityManager.getMemoryInfo( mInfo ); List<RunningAppProcessInfo> listOfRunningProcess = activityManager.getRunningAppProcesses(); Log.d(TAG, "XXSize: " + listOfRunningProcess.size());  for (RunningAppProcessInfo runningAppProcessInfo : listOfRunningProcess) {      if (runningAppProcessInfo.uid > 1026)     {         Log.d(TAG, "ANS " + runningAppProcessInfo.processName +                    " Id :" + runningAppProcessInfo.pid +                    " UID: " + runningAppProcessInfo.uid);     } } 

I tried the above code as suggested by Akos Cz. However all the UIDs are numbers, unlike app_79 as you have mentioned above. Is this all right?

Answer 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).

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.
