Android Battery Charging Status and broadcast

Below code can be used to query the battery status. This uses a sticky intent concept. 

        IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);

        Intent batteryStatus = registerReceiver(null, ifilter);

        // Are we charging / charged?

        int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1);

        boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||

                status == BatteryManager.BATTERY_STATUS_FULL;

        Log.v(LOG_TAG,"Charging status is :"+status);

        // How are we charging?

        int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);

        boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;

        boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;

        Log.v(LOG_TAG,"Charging Via :"+chargePlug);

        Intent batteryLevelIntent = new Intent(BROADCAST_ACTION);

        batteryLevelIntent.putExtra("chargingStatus",status);

        batteryLevelIntent.putExtra("chargingVia",chargePlug);

        batteryLevelIntent.putExtra("statusQueried",true);

        LocalBroadcastManager.getInstance(AppUtils.getAppContext()).sendBroadcast(intent);
