ObjectBox - DBException coming due to UID mismatching

I am using Objectbox as an ORM in my application and getting dbexception due to mismatching UID, when I added some extra properties in one of my entity. As I went through the documentation where it is mentioned that if we add or remove properties in your entities objectbox will take care of the changes. But it's not happening in my case. Please have a look at my log stash, entities and default.json once and let me know what could be the possible solution to resolve this issue.
ObjectBox version: v1.2.0

Entities
Previously my entity looks like this:
#Entity
public class BookingItem {
private long id;
#Id(assignable = true)
private long priority;
private String date;
private String formattedAddress;
private String orderId;
private String type;
private String title;

private String redirectUrl;
private String status;
private long experienceId;
private String shareableUrl;
private ToOne<Image> image;
private ToOne<FeedElement> feedElementToOne;
}
and my default.json looks like this:

In case you deleted the app/objectbox-models/default.json and uninstalled the app from your android device but the issue still prevails check your manifest file for android:allowBackup="true" and change it to false. Then repeat the steps again.
This cost me an hour of my life, hope it helps.
Source: The Nuke Option

Here's the solution as stated in the GitHub issue:
The IDs of the two versions in your project are totally off: https://www.diffchecker.com/PF3UlSM7
Please revert to the old "default.json" file and rebuild. There should only be little differences in this file on updates.

Yep. You probably changed your object structure after it created once.
The easiest option to solve it:
Like you said, If it possible you need to remove the default.json file (that build automatically while you build your project). and in the next build it will create again.
I recommend you to read about Resolving Meta Model Conflicts in objectbox documentation.

My issue is resolved and the issue actually is that I deleted my old default.json file by mistake which i didn't have to, which eventually led to regenerate the ids of all the entities and caused me a mismatching UID exception. Thanks to Markus Junginger.

How to pass object of json to other activity

I have this json

This data is of just one user. I have 50 of them.
I am still in learning stage and what I have done is that I have successfully listed all user in an activity. Now what I want to do is when I click on a user it should show it's related details in next activity...
List Users->Select Users->Show selected user details
I still don't know how to send data to other activity and display it.

How to obtain/parse JSONObject data with GSON

I am trying to use retrofit with android, which is kind of forcing me to use gson.
I am trying to get the data from the payload["response"]["docs"][0]["web_url"] in my code.
Issue : the key getResponse(), from below model class, always gives me {}. Whats the right way to handle this in android? Also note, the getCopyright() & getStatus() are working fine.
I am also providing the sample payload.
I have the model class like this :
public class ArticleSearchResponseModel {
#SerializedName("status") private String status;
#SerializedName("copyright") private String copyright;
#SerializedName("response") private JSONObject response;
public String getStatus() {
return status;
}
public String getCopyright() {
return copyright;
}
public JSONObject getResponse() {
return response;
}
public void setStatus(String status) {
this.status = status;
}
public void setCopyright(String copyright) {
this.copyright = copyright;
}
public void setResponse(JSONObject response) {
this.response = response;
}
}
My payload :
{
"response": {
"meta": {
"hits": 15987906,
"time": 108,

Before start, I'm not familiar with retrofit.
If you want serialize/unserialize json to pojo, you better make pojo object.
class Response {
Meta meta;
List<Docs> docs;
}
class Docs {
String webUrl;
Mutimedia multimedia;
...
}
The issue the key getResponse(), from below model class, always gives me {} happens because gson cannot determine proper object to convert json to plain old java object.

In order to make your Response model class use http://www.jsonschema2pojo.org/.
Making POJO simple

you no need to make exact structure in model
you can go ahead with your code just need small change
Use
#SerializedName("response") private JsonObject response;
instead of
#SerializedName("response") private JSONObject response;
and in the import
import com.google.gson.JsonObject;

And this is my Android Studio coding
public Product$$ModelHelper() {
fields.add(FieldMeta.builder().setId("productName").setName("name").setSqliteType("STRING").build());
fields.add(FieldMeta.builder().setId("productDescription").setName("description").setSqliteType("STRING").build());
fields.add(FieldMeta.builder().setId("sizetypecolor").setName("sizeTypeColor").setSqliteType("STRING").build());
fields.add(FieldMeta.builder().setId("image").setName("images").setArrayType("com.contentful.vault.Asset").build());
fields.add(FieldMeta.builder().setId("tags").setName("tags").setSqliteType("BLOB").setArrayType("java.lang.String").build());
fields.add(FieldMeta.builder().setId("categories").setName("categories").setArrayType("catalogue.contentful.vault.Category").build());
fields.add(FieldMeta.builder().setId("price").setName("price").setSqliteType("DOUBLE").build());
fields.add(FieldMeta.builder().setId("brand").setName("brand").setLinkType("ENTRY").build());
fields.add(FieldMeta.builder().setId("quantity").setName("quantity").setSqliteType("INT").build());
fields.add(FieldMeta.builder().setId("sku").setName("sku").setSqliteType("STRING").build());
fields.add(FieldMeta.builder().setId("website").setName("website").setSqliteType("STRING").build());
}
#Override

return fields;
}
#Override
public String getTableName() {
return "entry_ne90ogm2rdjxuxfnb2fvs2dzbtgysw";
}
My Android Studio project error screenshot
I really appreciate if anyone can help me with this problem.Because this app is a demo, i really think my problem is at my setting at CONTENTFUL, but maybe i need second opinion. Please help.
Thank you.

Hello Mario from Contentful here,
As I could see from the code you provided, it seems as if you changed the generated classes. Can you try changing the Product.java using the annotations provided by vault to create a Product matching your data?
This also needs to be done with all the other ContentTypes, you created in the Contentful-WebUI.
