how to get data usage from settings in android

问题

I'm trying to get 3g and wifi usage from Settings page in android, is there anyway to do that, i can set an intent Settings data usage page, code is below;

Intent intent = new Intent();
    intent.setComponent(new ComponentName("com.android.settings","com.android.settings.Settings$DataUsageSummaryActivity"));

    startActivity(intent);

But is there any way to reach these intent's component and to get data from those components.

Thankss..

Yes you can programmatically get the data usage

// 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);
}

Try this way And You can also refer this tutorial http://www.techrepublic.com/blog/software-engineer/create-a-network-monitor-using-androids-trafficstats-class/
