B4A Library FirebaseAdmin Library

I learnt Java in the past few months to build this library to get real-time updates from Firestore.
The Library has 5 classes:

• Firebase
• Firestore
• ListenerRegistration
• Query
• Filter
• Except RealtimeDatabase (Coming soon)

firebase-adminsdk.json(Service account file) from your Firebase console in Files/Assets
I had wanted it to be in the project folder like google-services.jon but couldn't figure how

In Sub Globals

Dim Firestore As Firestore
Public Firebase As  Firebase
Dim Listener As ListenerRegistration

In Activity_Create

Firebase.Initialize("Firebase","projectId")

An event is triggered when Firebase is Initialized which returns true or false where we can now Initialize Firestore

Private Sub Firebase_Ready(Success As Boolean)
    If Success Then
        Firestore.Initialize("Firestore",Firebase.GetFirebase,"(default)")
    End If
End Sub

Example Use:
Listen to changes in a collection or Document

Firestore.CollectionListen("products") 'Fetches the collection and its changes in real-time

Firestore.DocumentListen("products","documentID")

Private Sub Firestore_CollectionChanged(Data As Map)'Workds
    Log("Collection changed: " & Data)
    If Data.IsInitialized Then
        Dim Params As Map = Data.Get("data")
        Log(Data.Get("type"))
        Select Data.Get("type")
            Case Firestore.TYPE_ADDED
                ListView1.Add(AddPane(Params),Data.Get("id"))
            Case Firestore.TYPE_MODIFIED
                For i = 0 To ListView1.Size-1
                    Dim ID As String = ListView1.GetValue(i)
                    If ID == Data.Get("id") Then
                        Log($"Modifying: ${Data.Get("id")}"$)
                        ListView1.ReplaceAt(i,AddPane(Params),50dip,Data.Get("id"))
                        Return
                    End If
                Next
            Case Firestore.TYPE_REMOVED
                For i = 0 To ListView1.Size-1
                    Dim ID As String = ListView1.GetValue(i)
                    If ID == Data.Get("id") Then
                        ListView1.RemoveAt(i)
                        Return
                    End If
                Next
        End Select
    End If
End Sub

Get, Update or Delete Document

Dim map As Map
map.Initialize
map.Put("name","name_new")
map.Put("number",1234)
Dim list As List
list.Initialize
list.Add("item"&Rnd(10,100))
list.Add("item3")
map.Put("list",list)
Firestore.UpdateDocument("products","documentID",map)
Firestore.CreateDocument("products","",map)'Document ID can be empty
Firestore.DeleteDocument("products","documentID")

Remove Listener

Listener.Get(Firestore.CollectionListen("products"))'Must be called before removing

If Firestore.IsInitialized Then
    Listener.Remove
    Log("removed")
End If

Query & Filter

Dim query As Query
query.Initialize(Firestore.GetFirestore,"products").Limit(1).OrderBy("name").Get

Dim query As Query
Dim filter As Filter
filter.EqualTo("name","yes").GreaterThanOrEqualTo("number",10)
query.Initialize(Firestore.GetFirestore,"products").Where(filter).OrderBy("name").Get

Demo:

Note: This is new not advisable to use in projects yet and will conflict with existing firebase libraries
Will work on resolving that
I will work towards a B4X Library too if this is good

Version: 1.09:

Dim Path As PathBuilder
Path.Initialize.Append("users").Append("chats").Append("messages")
Log(Path.Complete)

Firebase.Initialize("Firebase","fir-*****")
Firestore.Initialize("Firestore","(default)") OR Firestore.Initialize("Firestore","")

Firebase.Initialize2("Firebase","fir-*****","https://fir-*****-rtdb.firebaseio.com",False)
Realtime.Initialize("Realtime")
Realtime.Child("users").SetValue("Claude Amadu")

Chat App Demo:

Demo:

The Video is set to "Private"? Should be "not listed"

Commendable effort If it is Firebase.

Still not yet?

Thanks! I will waiting for this

You can use it if you plan to build admin apps for monitoring the database and not publish on AppStore or Playstore because of the admin json file
