    ' send funds dont work ;-;

when i run in Release, show it on log :
Bash: 
*** mainpage: B4XPage_Appear
*** mainpage: B4XPage_Resize [mainpage]
0xdhfyr293jdh8aus929jdasak01923jdajjsldas 'my wallet
*** mainpage: B4XPage_Resize [mainpage]
*** mainpage: B4XPage_Resize [mainpage]
*** mainpage: B4XPage_Resize [mainpage]

after several minutes with the application open, the same log remains as above... looks like it's not calling send funds or something...

Start with this:
B4X: 
Private Sub B4XPage_Created (Root1 As B4XView)
    B4XPages.GetManager.LogEvents = True
    Root = Root1
    Root.LoadLayout("MainPage")
    Utils.Initialize
    Web3Ropsten = Utils.BuildWeb3Infura(InfuraRopstenLink)

    Dim credentials As W3Credentials = Utils.CreateCredentialsFromPrivateKey(Utils.BigIntFromHex(pk).ToByteArray)
    Wait For (Web3Ropsten.EthChainId) Complete (Result As W3AsyncResult)
    Log(Result.Value)
    Wait For (Web3Ropsten.EthGetBalance(credentials.Address, Utils.BLOCK_LATEST)) Complete (Result As W3AsyncResult)
    Log(Result)
End Sub

pk is a global string with the account private key. You can use a wallet instead.

If it doesn't work for you then something is misconfigured. Maybe your infura link or the set of libraries.

I tested this example code, but even so without a link to the wallet, there is no return... it's as if the http request was not made...

B4X: 
Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private Web3Ropsten As Web3X
    Private Utils As W3Utils
    Private InfuraRopstenLink As String = "https://ropsten.infura.io/v3/your_project_id_here"
End Sub

Public Sub Initialize
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    Utils.Initialize
    Web3Ropsten = Utils.BuildWeb3Infura(InfuraRopstenLink)
    Wait For (Web3Ropsten.EthBlockNumber) Complete (Result As W3AsyncResult)
    If Result.Success Then
        Log("Current block: " & Result.Value)
    End If
End Sub

I'm studying the web3x .bas to try to understand what's going on behind .


on line 75 of Web3X.bas when calling the example above, it gets stuck on RunAsync_Complete
as the screenshot above shows.

what is preventing the request?

My mistake, I forgot that to update the okhttp library, I would need to update the b4j root directory... ?
Thanks a lot for the help ?
