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.
I have download this CONTENTFUL CMS product catalogue demo ->https://github.com/contentful/product-catalogue-android. Im using android studio 1.4.
I have set the public token ID in the const.java accordingly but it still get error. At first i think maybe i have set a wrong setting at content_type field setting. But i still cannot find my solution. My error look like below and ive attached images for you to see,

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.

when I parsing this json object, String key "likes" is sometimes exist and sometimes do not exist in "data" jsonArray. So when I parsing JsonString "likes", sometimes I gets JSONException since I am parsing null value. Is there any way to skipping "null" json value?
Please help me regarding this.
if try catch it, next processes will be skipped.
you can check by isNull("name") method.
Edit: this is to check key. since you mentioned key exists sometimes. did you mean the value?
use JSONObjects method has(key)
data = (JSONObject) new JSONTokener(jsonObjRecv.toString()).nextValue();
if data.has("like"){
...
}
to check whether the value is null check with isNull("name")
