Why it is not returns the battery value ?

Hi

public void displayGattServices(List gattServices) {
if (gattServices == null) return;
String uuid;
String unknownServiceString;
unknownServiceString = getResources().getString(string.unknown_service);
String unknownCharaString;
unknownCharaString = getResources().getString(string.unknown_characteristic);
ArrayList<HashMap<String, String>> gattServiceData = new ArrayList<>();
ArrayList<ArrayList<HashMap<String, String>>> gattCharacteristicData
= new ArrayList<>();
ArrayList<ArrayList> mGattCharacteristics = new ArrayList<>();

    // Loops through available GATT Services.

    for (BluetoothGattService gattService : gattServices) {
        HashMap<String, String> currentServiceData = new HashMap<>();
        uuid = gattService.getUuid().toString();

        String LIST_NAME = "NAME";
        currentServiceData.put(
                LIST_NAME, SampleGattAttributes.lookup(uuid, unknownServiceString));
        String LIST_UUID = "UUID";
        currentServiceData.put(LIST_UUID, uuid);
        gattServiceData.add(currentServiceData);

        ArrayList<HashMap<String, String>> gattCharacteristicGroupData =
                new ArrayList<>();
        List<BluetoothGattCharacteristic> gattCharacteristics =
                gattService.getCharacteristics();
        ArrayList<BluetoothGattCharacteristic> charas =
                new ArrayList<>();

        // Loops through available Characteristics.
        for (BluetoothGattCharacteristic gattCharacteristic : gattCharacteristics) {
            charas.add(gattCharacteristic);
            HashMap<String, String> currentCharaData = new HashMap<>();
            uuid = gattCharacteristic.getUuid().toString();

            String gattInfo = SampleGattAttributes.lookup(uuid, unknownCharaString);
            if (gattInfo.equalsIgnoreCase("Heart Rate Measurement")) {
                currentCharaData.put(
                        LIST_NAME, SampleGattAttributes.lookup(uuid, unknownCharaString));
                currentCharaData.put(LIST_UUID, uuid);
                Utility.showLog("loop", uuid);
                mBluetoothLeService.setCharacteristicNotification(gattCharacteristic, true);
            }
            gattCharacteristicGroupData.add(currentCharaData);
        }
        mGattCharacteristics.add(charas);
        gattCharacteristicData.add(gattCharacteristicGroupData);
    }
}

It will not give Battery value. If i want battery and heart rate same time what i have to do?
