Android Question How do I see the contents of my JSON String?

[davepamn]

I need to inspect in debug my json string returning from the server.

The debug "copy to clipboard" truncates the data.

The JSON parser seems to throwing away some rows in the JSON string

Sub HandleContracts(Job As HttpJob)

    If Job.Success = False Then
        ToastMessageShow("Error downloading data.", True)
        ProgressDialogHide
        Return
    End If

    Dim TextReader1 As TextReader
    TextReader1.Initialize(Job.GetInputStream)

    Dim Text As String
    Text = StripTags(TextReader1.ReadAll )

     Dim p AsJSONParser
      RowMap.Initialize
      TableList.Initialize
      p.Initialize(Text)

end sub

Sub StripTags(sJSON As String) As String

    Dim Text As String=""
    Text = sJSON
    Do While Text.IndexOf(">")>0
             Dim StartTag As Int
             Dim EndTag As Int
            StartTag=Text.IndexOf("<")
            EndTag=Text.IndexOf(">")+1
            Dim S As StringBuilder
            S.Initialize
            S.Append(Text)
            S=S.Remove(StartTag,EndTag)
            Text=S.ToString
        Loop
    Return(Text)

End Sub

My program is getting the json string out of debug. I may try and write it to a text file

I may try and write it to a text file

or you may change the server side and just return less data so you can see the hole answer in the logs, copy it into the jsontree tool to create the b4a code for you

or put the url in your desktop/laptop browser

Where you want to inspect the string, insert this line:

File.WriteString(File.DirDefaultExternal, "myfile.txt")

Run the program and then you can inspect myfile.txt file with the complete string.
You can also copy myfile.txt from device to a PC and open it with your editor

File.WriteString(File.DirDefaultExternal,"myFile.txt",myJSONString)

I was able to inspect the json string using a tablet editor.

I was able to shorting the json string but it still exceed 4000 characters. In my opinion, b4a needs to improve the debug capabilities and features.

This was an excellent tool. I saved my json string to file, transferred the file to my desktop, and cut and paste the json string in the html page and parsed it. The json parsed correctly and helped me feel confident in the parser.
