Android Question Problem with Firebase

[mariosteffen]

Hi, folks.
I am developing a system which uses a Firebase database. I am using B4A 8.0 and the libraries are JSON version 1.1, OkHttp version 1.2 and OkHttpUtils2 version 2.61.
Everything works fine if I set the rules of the database as read: true and write: true. I want to change both rules to false, to protect my data. The only functions I want to use of Firebase are to read from and write on the database. I do not need other functions like PUSH messages, for example.
I could not find any example of what parameters I have to specify if I change the rules to false. Does anybody have an example ? My code is below.
I tried to use the CODE tool on this post, but it did not work.

Code to write on the database

Sub PostOnDatabase
Dim Job As HttpJob
Job.Initialize("fcm", Me)
Dim m As Map = CreateMap(Chave:Conteudo)
Dim jg As JSONGenerator
UrlPost="https://xyzabc.firebaseio.com/abcd.json"
jg.Initialize(m)
Job.PostString(UrlPost, jg.ToString)
Job.GetRequest.SetContentType("application/json;charset=UTF-8")
Job.GetRequest.SetHeader("Authorization", "key=" & "HereiITheKeyICopiedFromFirebase")
End Sub

Sub JobDone (Job As HttpJob)
Log(Job)
If Job.Success Then
Log(Job.GetString)
End If
Job.Release
End Sub

Thanks for your help.

How would you allow to read the data if you set READ to false in the rules? This Rule will prevent everyone from READING any Data.

Hi, DonManfred. I want to set authorizations for both options: read and write.
The FALSE on the READ option is to prevent unauthorized people to access your data.

This are the parameters I am talking about:

I did understand what you are talking about

If that does not help then you need to Check their Documentation (Firebase) on how to set the rules you want.
