Android Question resumable sub and debug/release mode

[akinnovation1]

Hi,
I have a trouble with my app.
The app is fine when I run it in debug mode, but crash in release mode.

I attach the resumable subs that crash

public Sub Leggiscrivi(stringa As String)As ResumableSub

    Dim b() As Byte = stringa.GetBytes("UTF-8")
    Log("leggiscivi: "&stringa)

    o.WriteBytes(b,0,b.Length)
    o.Flush

    i=sckt.InputStream
 
    Dim buffer(1024) As Byte
    Dim count As Int = 0
    Dim length As Int = 0
        
    Dim risposta As String
    risposta="N"
    'response loop (need exit condition)
    Do Until count=-1
        'Log("Do until "&count)
        'you can also send here more
        length = i.BytesAvailable '?
        count = i.ReadBytes(buffer, 0, length)
        Sleep(10)
        If (length>0) Then
            Dim risposta As String
            Log("avail "&length)

and the function that call this function

Sub GestisciTag 
    Dim crs As Cursor 
    Dim str As String

        If crs.RowCount>0 Then ' è un operatore
            crs.Position=0
            If parametri.controllo Then

                wait for(controllo_g1.attendiInit) complete (result As Boolean)
                If result Then
                    Log("collegato")
                    Dim message,risposta As String
                    message= "?alfa?,"&crs.GetString("codfisc")&","&crs.GetString("piva")&","&"180283"&Chr(10)&Chr(13)

                    If risposta.StartsWith("S") Then
                        Smile.Bitmap=LoadBitmap(File.DirAssets,"spuntaverde.png")
                        Smile.invalidate
                        vedismile(True)
                    Else

                        ora.TextColor=Colors.White
                        ora.TextSize=12
                        ora.Text="NON PUO' ENTRARE "&Chr(10)&Chr(13)&risposta.SubString2(2,risposta.IndexOf("#"))
                    End If
                    refresh.Enabled=True
                End If

this is a sub in main

Many many thanks to your help

You should use AsyncStreams. Never make network communication on the main thread.

Why are you asking the same question again when it has already been answered?

resumablesubs and debug/release app

Hi, I have an app with resumablesubs that crash when I compile it in release mode, but work fine if I use it compiled in debug mode ! controllo_g$ResumableSub_Leggiscriviresume (java line: 145) android.os.NetworkOnMainThreadException at...

Why are you asking the same question again when it has already been answered?

Unfortunately, many trust the answers only if they come from Erel. In fact, I noticed that some members wait when they know Erel is active in the forum and ask their questions, because they think they have a better chance of getting the answer from Erel. It is unfortunate, because amost of us who answer make a great effort in providing good and reliable answers with nothing in return.

Unfortunately, many trust the answers only if they come from Erel.

I'm not sure that this is the case here. Both questions were posted on Friday.

Many many thank you to all your help.
I have separate the network communication from main thread and have used the async streams and all is OK now.
Many thanks to all community, that is one of the strong points of B4X.
