    Default Android 2.3.3. JSON bug (JSON string twice in responseText)

    Android 2.3.3. JSON bug (JSON string twice in responseText)


    Hi all,

    we bumped in a very strange bug on Android 2.3.3.
    All ajax calls that expect a JSON object fail with "Unable to parse the JSON returned by the server.." due to a doubled JSON string. So instead of
    Code:
    {"key":"value"}
    the reponseText contains
    Code:
    {"key":"value"}{"key":"value"}
    On Android 2.1 and Android 3.1 this problem does not occur.

    Can anybody confirm this behavior?

    Best Regards
    Sebastian

    The response has the double object? If so then that is not valid JSON and therefor not consumable.

    Yes, correct. The bug occurs due to an OPTION request sent in chrome browsers. We fixed this by
    Code:
    Ext.Ajax.useDefaultXhrHeader = false;
    and responding only to POST and GET on ther server.
