Initial commit.
Draft finished. Figure out how to embed layout later.
Knew how to embed layout in android.
Unify intentation with softtab 4.
Fixed a bug and give user feedback when set status.
Finished enlabing bluetooth at startup.
Remove unecessary file.
Done some clean up.
Make ConfirmationDialogFrament class more generic.
Added an ugly scan button, which is used to scan for the wearable for
the first time when the user uses it and provides a user-friendly way to
let user choose their wearable. After that, the app will connect to
their wearable automatically. This is the stub for future
implementation. They are not implemented.
Since we will use bluetooth GATT to communicate, I dropped writing code
about code for the moment.
Now google map can successfully run.
Now user can set camera to its location.
Clean up is made. Almost no redundant code.
Rather detailed Comments added.
Now app can display map, show the location of user on map and let user
input start location and destination, but locations actually is not used
yet.
Some refactor and more comments.
Google Play Service Check finishes.
Address auto completion done.
Refactoring and more comments.
Again... more comments.
Now the app can utilize Google Direction service to acquire all the
routing information from origin to destination input by the user.

However, note that for convenience of testing, request url to Google
Direction Service is hard coded for the time being.
Now route is drawn on the map with camera right.
