GeoFire Step-by-Step Tutorial Android

[Reuben Cabrera]

I cannot find any tutorials regarding how to use Geofire in Android. is there any other tutorial for this? 

it seems that https://github.com/firebase/geofire-java is not updated?

what I want to accomplish is.

Assumptions: user is logged in.

1. user can see his current location and updates the DB

2. When user presses "search nearby people", user is able to view online users within a 2km radius.

any help or any sample code will be appreciated thank you :)

Hey Reuben,

What about that repo is not updated? I believe the README should be completely up-to-date. You can find the full API reference here.

1. user can see his current location and updates the DB

You would need to use the Android API for getting a user's location and then you can add that to the GeoFire index via setLocation().

2. When user presses "search nearby people", user is able to view online users within a 2km radius.

You'd use a GeoQuery to do this. Check the API reference for it's API.

Any sample code will be appreciated

Check out the FSVehicles example here.

Cheers,

Jacob

Do I need to store my Location to my Database?

[Jacob Wenger]

If you just want to query locations close to your current location, just create a GeoQuery and you don't need to store your location. If you want others to query on your location, then yes, you'll need to store that in your GeoFire index.

Cheers,
Jacob

I tried the SFVehicles, where does the nearby location data come from? does it come from the DB?

i dont understand how it puts multiple markers using the hashmap. 

@Override
public void onKeyEntered(String key, GeoLocation location) {
    // Add a new marker to the map
    Marker marker = this.map.addMarker(new MarkerOptions().position(new LatLng(location.latitude, location.longitude)));
    this.markers.put(key, marker);
}

I was kinda expecting a loop to see all within tthe given radius

The onKeyEntered() callback is fired for every key in your GeoFire index which matches your GeoQuery. The GeoFire library itself will call that method when appropriate. All you need to do is respond to the event.

Hope that helps,

Jacob

I see. so I manage to finally get some markers setup so what I want to do next when I click on that marker I can send him/her a message. is that possible through Firebase cloud messaging? or with the use of notifications?

If you just want messages in the sense of a chat, you can make use of the Realtime Database. If you want messages in the sense of push messages, you can't actually send push messages directly via the web SDK. But you can set up your own messaging server and receive push messages on the web as documented here.

for example, I want to send a message to a specific user, can I use his/her corresponding userID to send him/her a message or a notification? correct me if im wrong but that is not how push notifications work

[Jacob Wenger]

Hey Reuben,

I would suggest using the Firebase Realtime Database for this task, not Firebase Messaging.
