    text
    copied!<p>I am using the Kinvey Android SDK to retrieve data from their backend. It uses Gson behind the scenes. I have been unable to get it to deserialize an array of custom objects. Here is the entity definition and the JSON in question:</p> <pre><code>public class AlbumEntity extends GenericJson { @Key("_id") private String id; @Key private String name; @Key private String location_name; @Key private String start_date; @Key("artifacts") private Artifact[] artifacts; static class Artifact extends GenericJson { @Key private String type; @Key private String photo_url; public Artifact() {} } @Key("_kmd") private KinveyMetaData meta; public TripketEntity() {} } </code></pre> <p>JSON body:</p> <pre><code>{ "_id": "5216fec12f7b521a26064f9d", "_kmd": { "ect": "2013-08-26T06:51:00.283Z", "lmt": "2013-09-05T15:28:28.079Z" }, "artifacts": [ { "type": "photo", "photo_url": "http://www.califliving.com/title24-energy/images/sanfrancisco.jpg" }, { "type": "photo", "photo_url": "http://www.sanfrancisco.net/pictures/san-francisco.jpg" }, { "type": "photo", "photo_url": "http://a2.cdn-hotels.com/images/themedcontent/en_GB/San%20Francisco_Top%2010.jpg" }, { "type": "photo", "photo_url": "http://sanfranciscoforyou.com/wp-content/uploads/2010/03/san-francisco-city.jpg" } ], "location_name": "San Francisco", "name": "My Trip to the Bay", "start_date": "06/15/2013", "owner": { "_type": "KinveyRef", "_collection": "user", "_id": "5216fcd60b36c57d69000529" }, "_acl": { "creator": "kid_ePPs9jXc_5" } } </code></pre> <p>If I change the <code>private Artifact[] artifacts</code> object to <code>private GenericJson[] artifacts</code>, the array is deserialized as an array of GenericJson objects, with the data fields intact in the Unknown Fields list. How can I get it to work for my custom object?</p> <p>Other things I have tried include <code>List&lt;Artifact&gt; artifacts</code> as well as ArrayList and Collection.</p>
