Android Question Save image to string

[JDS]

Hi all,

What we are trying to do is to send an image via xml.
I'm using the CameraExClass to take a picture (max width 1280) and we encode this to B64 (EncodeBtoS). xML-string is created but after a few pictures the application hangs. the XML-string is null. Any thoughts?

Sub Camera1_PictureTaken (Data() As Byte)
    Dim sXMLFile,sTime As String
    
    DataFoto = Data
    sTime = Globaal.getTimeNoLimiter
    sFotoFilename = iZendingID & "_" & sTime & ".jpg"
   
    camEx.SavePictureToFile(DataFoto, File.DirInternal, sFotoFilename)
    camEx.StartPreview 'restart preview
    oImageView.Bitmap = LoadBitmap(File.DirInternal,sFotoFilename)
    
    Dim B64 As Base64
    camEx.Release
    sFile=""
    sFile = B64.EncodeBtoS(DataFoto,0,DataFoto.Length-1)
    iPressBack = 1
    sDate = Globaal.GetDate
    sTime = Globaal.GetTime
    sLon = (Globaal.GPS_Long/1000000)
    sLat = (Globaal.GPS_Lat/1000000)
    sOms = ""
    sOms = EditText1.Text.Trim
    sXML = ""
    sXML = "<zending><foto>"
    sXML = sXML & "<f01>" & Globaal.PDAID             & "</f01>"
    sXML = sXML & "<f02>" & Globaal.def_Datum         & "</f02>"
    sXML = sXML & "<f03>" & Globaal.def_RID         & "</f03>"
    sXML = sXML & "<f04>" & sTime                     & "</f04>"
    sXML = sXML & "<f05>" & sDate                    & "</f05>"
    sXML = sXML & "<f06>" & iZendingID                 & "</f06>"
    sXML = sXML & "<f07>" & sFotoFilename            & "</f07>"
    sXML = sXML & "<f08>" & sFile                    & "</f08>"
    sXML = sXML & "<f09>" & sLon                    & "</f09>" 'sometimes the app fails here
    sXML = sXML & "<f10>" & sLat                    & "</f10>"
    sXML = sXML & "<f11>" & sOms                    & "</f11>"
    sXML = sXML & "</foto></zending>"
    sTime = Globaal.getTimeNoLimiter
    sXMLFile = Globaal.PDAID & "-" & sTime & "-" & iZendingID & ".xml"
   
    If (sXMLFile <>"" AND sXML<>"") Then 'most of the time the application fails at "sXML<>"" "
        File.WriteString(Globaal.Map_Foto, sXMLFile, sXML)
        iPressBack = 0
        ProgressDialogHide
       
        camEx.Release
       
        Activity.Finish
    Else
        iPressBack = 0
        ProgressDialogHide
        ToastMessageShow("Bestandsopbouw mislukt. Probeer nogmaals.", True)
    End If
End Sub

The error which is given:

(Line: 278) If (sXMLFile <>"" AND sXML<>"") Then

Might be a memory issue (the string can be huge). Try it in Release mode.
