Android Question My widget works when installed with USB crashes when I use B4A Bridge install

My widget works when installed with USB crashes when I use B4A Bridge install

This is the exception I get. This is a release not debug build with some Log() statements.

Thanks,
Bill

Can you post the code in ParseWxxml ?

 

[Bill Kantz]

Sub ParseWxXML(Job As HttpJob)
out.Initialize(File.OpenOutput (File.DirRootExternal,"wx.txt",False))
Log("Job Complete")
parser.Parse(Job.GetInputStream, "Parser")
Log("parse complete")
out.Close
End Sub


Sub Parser_StartElement (Uri As String, name As String, Attributes As Attributes)
Dim count As Int
count = Attributes.size - 1
For x = 0 To count
out.Writeline( Attributes.GetName(x))
out.Writeline(Attributes.Getvalue(x))
Next
' For x = 0 To count
' Log(sname(x))
' Log(svalue(x))
' Next
End Sub

Sub Parser_EndElement (Uri As String, name As String, Text As StringBuilder)
out.Writeline(name)
out.WriteLine(Text)
End Sub

 

[Erel]

It should be:

out = File.OpenOutput(...)

 

[Bill Kantz]

or is it i forgot:

DIM out as TextWriter

Now i'm not sure how it worked at all? WriteLine() is a member of Textwriter object not File object?

 

[Erel]

I didn't know that out is a TextWriter. Your code is correct.

The external storage is probably not writable because it is connected to the PC. You should check it with File.ExternalWritable. If it is not writable then you should use the internal storage instead.

Thanks Erel!

The problem was that I did forgot to add "DIM out as TextWriter" to Sub ParseWxXML(Job As HttpJob). Thank for the help I would have chased that one for a while.
