Access device contacts

[iamhssingh]

The PWA should be able to access contacts from user's system with user's permission. This will allow one to directly select name from phone book.

How should we accept data?
Say one user selects a Contact A from the system. Prepare a JSONObject in following form:
{ "name": "Contact A", "mobile": "xxxxxxxx", "home": "xxxxxxx", "email": "[email protected]" }
The data should be sent as the value in API. The BackEnd system will automatically accept this data. In case data has been fetched from the backend system, an id key value pair can be added in the Object.
