An app to broadcast SOS for help to users of a particular pincode.

API used

-> Firebase Cloud Messaging
-> FusedLocationProvider
-> Covid-19India API

Tech Stack Used

-> Google Firebase - for broadcasting message

How it works

Authentication and Registration

we have hosted the backend(PHP files and MySql) on 000webhost in which authentication and varification API is created using PHP and Myql is used as database Volley is used for making the requests

Covid-19 India Real-Time Stats

for getting the real-time data we are using Covid-19India API and we are making request through okHttp and converting response json to objects through Gson converter liberary and then we are displaying the data.

SOS Alert

We have used Publisher-Subscriber model here. we are using Pincodes as topics that users have subscribed and we are pushing the notification through firebase cloud messaging API to the users which have subscribed same topics (Pincode).

the notification that user get contains

 1) SOS message title and discription

 2) Name of the sender

 3) Phone No. of sender

 4) Location of the sender

 -> we are sending location as coordinates(latitude,longitude) and on clicking Locate on map button 
 we are showing that coordinate on Google maps.
