Get Data from Android Wear Smartwatch to Smartphone

I made several apps (pedometer, heart rate, audio recorder) for moto360 with android wear. everything works fine, but I don't know how to save data on watch and how to access data on smartphone. I was able to send messages to the watch, but I cannot send data from phone to phone. I can save my data on my smartphone, but I don't know how to manage it on the smartwatch. can anyone show me a tutorial or example? Thank you very much!

edit: The following code below is used to track heart rate on Moto360 and it works great. I tried to transfer data from hour to phone to use this tutorial -> https://developer.android.com/training/wearables/data-layer/data-items.html

After injecting the code on the android page, I couldn't run the project on the device!

    public class MainActivity extends Activity implements SensorEventListener {


        private static final String TAG = "MainActivity";
        private TextView mTextViewStepCount;

        GoogleApiClient mGoogleApiClient;

        @Override
        protected void onCreate(Bundle savedInstanceState) {


            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

            super.onCreate(savedInstanceState);
