Android Question Error with B4A Socket

[davideb]

I've tried the old socket example.
All goes correctly with debug, but when i go to the release mode, the app break and give me this exception.

(NetworkOnMainThreadException) android.os.NetworkOnMainThreadException

Sub Timer1_Tick
    Dim BC As ByteConverter
    
    If InputStream1.BytesAvailable > 0 Then
        Timer1.Enabled = False
        
        Dim buffer(8192) As Byte
'        'raf.Initialize3(buffer, True)
    Try
         InputStream1.ReadBytes(buffer, 0, buffer.Length)
    Catch
        Log(LastException)
    End Try
      
'        Dim s As String=BC.StringFromBytes(buffer,"UTF-8")
'        lblArt1.Text=s
        'Timer1.Enabled = True
    End If
End Sub

Workaround the NetworkOnMainThread exception

Android 4+ doesn't allow applications to make network calls on the main thread. There is a good reason for this restriction as such calls cause the UI to freeze and after 5 second Android will show the "Application not responding" dialog. Proper libraries take care of handling network calls...

It doesn't run perfectly. You should use AsyncStreams. Any other solution will break at some point and will cause your app to freeze.
