* this activity if the phone permission hasn't been approved for the data wear is trying to access.
|

* When the user decides within this Activity what to do with the permission request, it closes and
|
|
* opens the MainPhoneActivity (to maintain the app experience). It also again passes along the same
|
|
* extra (MainPhoneActivity.EXTRA_PROMPT_PERMISSION_FROM_WEAR) to alert MainPhoneActivity to
|
|
* send the results of the user's decision to the wear device.
