Android Question Problem with JSON deserialiser

[Yayou49]

Hello everyone,

After a call to a webservice, I have job1.getString whit the following value:

[{"siteId": 7,"siteLibelle": "Belgium"},
{"siteId": 18,"siteLibelle": "Chile"},
{"siteId": 22,"siteLibelle": "Colombia"}]

Using the code provided by Erel:

Dim JSON As JSONParser
Dim Map1 As Map
    
JSON.Initialize(Job1.GetString)
Map1 = JSON.NextObject

I've got an error on line:

Map1 = JSON.NextObject

Which is:

Error occurred on line: 108 (ParserJSON)
java.lang.RuntimeException: JSON Object expected.
at anywheresoftware.b4a.objects.collections.JSONParser.NextObject(JSONParser.java:50)

It seems "[" and "]" are not accepted at the beginning of the string .....
Indeed, if I remove both from the string, it works ....
But they are part of JSON coding ...

Any idea ?

This is the correct code:

Dim parser As JSONParser 
parser.Initialize(<text>) '<--- Modify this line adding your JSON string.
Dim root As List = parser.NextArray 
For Each colroot As Map In root 
 Dim siteLibelle As String = colroot.Get("siteLibelle") 
 Dim siteId As Int = colroot.Get("siteId") 
Next

Try THIS tool.

Thanks NJDude !

It works fine !

But still the question (for my own understanding): why [ and ] are not allowed in my example ?..... that is the question ....

Depends on the JSON string, in this case you should use NextArray and not NextObject.

For more info read the tutorial on top of the screen (under Similar threads).
