your mistake is in this line

B4X:

    Wait For (j) JobDone(j As HttpJob)

you declare at the top the httpJob as "http" so you need to wait when "http" is executed and not if j (that is the response httpjob)

just change this line to:

B4X:

Wait For (http) JobDone(j As HttpJob)

I think in a standard class "Me" can not be given as a Target to httpjob.

    If j.Success Then
        Log("yes")
    Else
        Log("no")
    End If
    j.Release

    Private a As MyLibrary
    a.initialize

why are you changing the standard b4a context?

the error you get is very clear:


change your class to this:

B4X:

Public Sub initialize
    download
End Sub

Public Sub download
    Private http As HttpJob
    http.Initialize("http",Me)
    http.Download("https://cdn.shortpixel.ai/client/q_glossy,ret_img/https://www.b4x.com/basic4android/images/dopus_NucbTJkLV0.png")
  
    Wait For (http) JobDone(j As HttpJob)
    If j.Success Then
        Log("yes")
    Else
        Log("no")
    End If
    j.Release
End Sub

call the class like this:

B4X:

    Private a As MyLibrary
    a.initialize
