HelloAccessoryProvider: Android side project.
In folder ‘assets’ there is a HelloAccessoryConsumer_iGear.wgt which
can be created by building watch project. Simply copy the wgt file into
‘asset’ and when the android project is uploaded to phone, it installs
automatically on the watch.

On the watch, click on ‘connect’ button to create communication channel
between watch and phone. Click on ‘fetch’ will send accelerometer data
to the phone and the phone pushes the data back to the watch upon
receiving. The data is also shown on the watch.
