Android Question websocket error

[nicolino33]

Hello all, I have one problem:

Dim ws As WebSocket
ws.Initialize("ws")
Dim url As String = "wss://stream.binance.com:9443/ws/bnbusdt@miniTicker"
ws.Connect(url)

Error: java.lang.Exception: Sub ws_connected signature does not match expected signature.
public static anywheresoftware.b4a.pc.RemoteObject b4a.example.b4xmainpage_subs_0._ws_connected(anywheresoftware.b4a.pc.RemoteObject,anywheresoftware.b4a.pc.RemoteObject) throws java.lang.Exception

Could you help me?

Sub ws_connected signature does not match expected signature.

how does the sub signature look like?

 

[nicolino33]

how does the sub signature look like?

The only thing I see is just the error I reported, there are no other indications

Noone can help if you do not post it!

This is all I see in the error report, and the code that runs is just what I wrote earlier, where can I find the signature?

Last try:

Post the complete sub ws_connected

Sub ConnectToBinanceWebSocket()
    Public rp As RuntimePermissions
    rp.CheckAndRequest("INTERNET")
    
    Dim ws As WebSocket
    ws.Initialize("ws")

Last try:

Post the complete sub ws_connected

Sub ws_Connected (WebSocket1 As WebSocket)
    Log("Connessione WebSocket stabilita")
End Sub

 

[DonManfred]

I give up....

I asked you to post the sub ws_connected and you posted sub ConnectToBinanceWebSocket?

I´m out here

Sub ws_Connected
    Log("Connessione WebSocket stabilita")
End Sub

 

[DonManfred]

B4A - WebSocket

See the events listed there...

I asked you to post the sub ws_connected and you posted sub ConnectToBinanceWebSocket?

I´m out here

Sub ws_Connected
    Log("Connessione WebSocket stabilita")

I posted both!

To get always the correct sub signatures, you should:

(pressing TAB)

 

[nicolino33]

B4A - WebSocket

See the events listed there...

i don't understand.... the event is "connected" and the websocket is ws, the sub ws_Connected should be right, right?

 

[DonManfred]

ws_Connected should be right, right?

without any parameters, yes.

 

[nicolino33]

without any parameters, yes.

ok i removed the sub..... now it works! Thank you!

Did you "watch" my previous post? ? ?

(Ok, I wrote "Websocket1", instead of "ws", ma it's the same, you must enter the event name associated to the object, websocket object in this case)

Yes, thanks!

 

[DonManfred]

you used websocket_connected there. But it will not work this way as he used ws as prefix. So the subname should be ws_connected

 

[LucaMs]

Yes, thanks!

So you wouldn't have needed to ask for confirmation that the sub should be without parameters, the editor itself "tells" you.

Yes, this is why a few moments ago I added:
