Android Question Error with httpjob on some devices

[djmainero]

Hello!
I uploaded my app to google play and when testing in some devices i get this error

FATAL EXCEPTION: main
java.io.FileNotFoundException: /data/data/com.sysoluciones.micoop/cache/1: open failed: ENOENT (No such file or directory)

In this case the error is on Galaxy S3 (SDK 18)

What could be causing it?

Thanks in advance!

You are not checking that Job.Success is true.

Thanks for the response

I'am checking that

Dim JobString As String
    Dim cadena As Map
    cadena.Initialize
    cadena.Put ("Accion", "GetCooperativas")
    
    Glo.lCooperativas.Initialize
    ht.Ejecuta(Me, cadena, Glo.sysURL)
    Wait For JobDone(Job As HttpJob)
    If(Not(Job.Success)) Then ' <- Here
        Return False
    End If
    JobString = Job.GetString
    Job.Release
    Dim su As StringUtils
    Dim b() As Byte
    b = su.DecodeBase64(JobString)
    Glo.lCooperativas = fCom.decoJSON3(BytesToString(b, 0, b.Length, "UTF8"))

Sub Ejecuta(Act As Object, cadena As Map, url As String)
    Dim j As HttpJob
    j.Initialize("j", Act)
    j.PostString(url, fCom.encoJSON(cadena))
    j.GetRequest.SetContentType("application/json")
    j.GetRequest.SetHeader("Authorization", Glo.Bearer)
    j.GetRequest.Timeout = 20000
End Sub

If(Not(Job.Success)) Then ' <- Here Return False

You are NOT releasing the job in case it is false.

 

[djmainero]

Thank you! I will try it

You are NOT releasing the job in case it is false.

That's true and it should be fixed, but it is not the cause of this error.

Not elegant:

Dim cadena As Map
    cadena.Initialize
    cadena.Put ("Accion", "GetCooperativas")

Elegant:

Dim cadena As Map = CreateMap("Accion": "GetCooperativas")

The error is probably here:

 Wait For JobDone(Job As HttpJob)

The explanation is in the resumable subs video tutorial: https://www.b4x.com/etp.html
