Is it possible store complex objects?

[dsdebastiani]

I'm trying to store a complex object (object with custom class atributes, and lists), but my app is freezing when it's executed Hawk.put("KEY", coplexObject);. Only freezing. No crashing, no closing, nothing.

The object which I'm trying to store is like:

public class ComplexObject {
  private AnotherComplexObject attr;
  private List<AnotherComplexObject_2> listAttr;
  private long attr2;

// getters and setters
...
}

This object come from a REST API and I'm using Retrofit with Gson. I'd like to just store it.

Does Hawk support this kind of objects?

Thanks for help.

Hawk uses gson to convert object to string. There shouldn't be any problem with that. I could check this one with test case to see if it works. There might be different reason. Maybe the object contains too much data and it takes a little while to convert it. Can you try with a background worker? Or if you put the exact object here, I can try as well with a test case.

i also meet the same problem, my complex object is come from a REST API and i using Retrofit with gson, the response json string like this:

{
"code": 200,
"message": "success",
"requestUri": "/v1/banners/list",
"data": [
{
"bannerId": 2,
"title": "中文超级长标题的test看看这个标题够不够长啊 ",
"displayorder": 1,
"imageUrl": "http://xxxxx/group2/M00/5F/EA/rBADO1Yco_GAWjhTAANNzCyLAVI134.png"
},
{
"bannerId": 6,
"title": "333",
"displayorder": 2,
"imageUrl": "http://xxxx/group2/M00/5F/EA/rBADO1YcouaAd5pTAAGIDOTG3nA618.png"
}
],
extra: {
"customParam": "",
"cacheUpdateTime": -1
}
}

I use two object to covert this json string:

public class BaseEntity<T extends DataSupportBase> implements Serializable {

    private int code;
    private String message;
    private String requestUri;
    private List<T> data;
    private Object extra;
}

public class BannerInfo extends DataSupportBase {

    private int bannerId;
    private String title;
    private int displayorder;
    private String imageUrl;
}

then, in my code i use BaseEntity to encapsulation it, print it

BaseEntity{code=200, message='success', requestUri='/banners/list', data=[BannerInfo{bannerId=34, title='长图长图-简约不简单', displayorder=21, imageUrl='http://xxxx/group2/M00/34/02/rBADO1aOOwGAIqbnAApB_alyZmo924.png'}, BannerInfo{bannerId=98, title='khz-测试-0112-1', displayorder=6291461, imageUrl='http://xxxx/group2/M00/3B/1E/rBADO1aU4d-AYWhFAAvWFkcZHjA200.png'}], extra={customParam=, cacheUpdateTime=-1.0}}

when i use Hawk.put("banner", banner)

when i use Hawk.get("banner") to get the store object, it return

BaseEntity{code=200, message='success', requestUri='/banners/list', data=[{bannerId=34.0, displayorder=21.0, imageUrl=http://xxxx/group2/M00/34/02/rBADO1aOOwGAIqbnAApB_alyZmo924.png, title=长图长图-简约不简单, baseObjId=0.0}, {bannerId=98.0, displayorder=6291461.0, imageUrl=http://xxxx/group2/M00/3B/1E/rBADO1aU4d-AYWhFAAvWFkcZHjA200.png, title=khz-测试-0112-1, baseObjId=0.0}], extra={customParam=, cacheUpdateTime=-1.0}}

then there is a error : error ........java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to BannerInfo

there are some different between before stored and after stored , maybe you can test it with these objects, wish to recieve your answer as soon as possible

Sorry for very late response. Is this still an issue?

[orhanobut]

Closing this issue for now, we can definitely re-open if needed
