Android版带谷歌地图的实时数据库

Question

we have a android project that needs the following objectives:

*we also have a web application for this app that needs to communicate with the same database as the android application

what I have done so far:

1. a view of a map with a pinpoint on my current Location
2. mysql db containing information (including latitude and longtitude position)
3. registration and login

Real Time Database Objectives:

1. state that people are online or offline(updating a database).

Google Map Objectives:

1. When I press a button, the map will show other users who are online within a given radius so basically I need to view online people who are near me

2. Send a message to them [2 ways]

2.1 I send them a message by clicking their icon

2.2 I send everyone[online people within the radius] the message

Questions:

1. 1. I am currently using php mysql for login/register. Can I use this for a real time database or is there any other way?
2. is Firebase somehow similar to a hosting site?

if there are other needed information needed, pls inform me, I may not have included information that could help with my questions :) ill update my question too if I have more questions.

thank you.

Answer 1

I think for your requirements its is more appropriate to use Firebase as it fulfills all your expectations and provides additional features.
