Content.class and CountryRelated.class have same structure
after i do article.save() my lists doesnt save . Am i doing something wrong or it doesnt save lists at all ???
I few things to look at.
First. I do not believe that the database will handle a column with the type of List or a type of other Object. When I tried running your code, I received:
Class cannot be read from Sqlite3 database. Please check the type of field categories(java.util.List)
These should be types the database can store. Try serializing your List(s) to Strings to insert them in the db. You can try doing this in your getter and setter. The setter takes the list of objects and converts it to a serialized String, the getter takes the serialized String and converts it back to a list of objects.
In the instance of SugarOrm, you can reference another table and it will create a relationship outlined here:
http://satyan.github.io/sugar/creation.html#why
Notice the "Author" type is just referencing a record from another table in the database.
Second I usually try and set my default values inside my default constructor. so something like:
... property declarations...
public Article() {
this.name = "Default Value";
}
Hope this helps you finish troublshooting!

My application works well in debug mode, I Generated a signed Android app bundle and tested it by firebase test lab but app crashed during testing.
the test shows Fatal exception :

I am trying to insert realm lists to my realmdb in my first insert there is no problem but when I insert another realmList with a different class, my old values are deleted. So how can I insert a realmlist to DB? inserts are done separately.
RealmList<Product> insertedProduct = new RealmList<Product>();
RealmList<ProductSubCategory> insertedSubCategory = new RealmList<ProductSubCategory>();
RealmList<ProductMainCategory> insertedMainCategory = new RealmList<ProductMainCategory>();
... inserting to realm list firt time ...
insertRealmList(insertedProduct); //inserting to realmDB first time
insertRealmList(insertedSubCategory); //inserting to realmDB first time
insertRealmList(insertedMainCategory); //inserting to realmDB first time
first insert to realmDB
RealmList insert function
private void insertRealmList(final RealmList realmObject) {
mRealm = Realm.getDefaultInstance();
realmTask = mRealm.executeTransactionAsync(
new Realm.Transaction() {
#Override
public void execute(Realm realm) {
realm.copyToRealmOrUpdate(realmObject);
}
},
new Realm.Transaction.OnSuccess() {
#Override
public void onSuccess() {
Log.i(TAG, "onSuccess: successfully inserted data");
}
},
new Realm.Transaction.OnError() {
#Override
public void onError(Throwable error) {
Log.i(TAG, "onError: error while inserting " + "error: " + error);
}
}
);
}
... inserting to realm list second time...
insertRealmList(insertedLanguages); //insert realmDB second time
second insert to realmDB

Other two models are similar with product.
Please try the following method:
private <T extends RealmModel> void insertRealmList(final List<T> objects) {
try (Realm realmInstance = Realm.getDefaultInstance()) {
realmInstance.executeTransaction(realm -> {
for (T object : objects) {
realmInstance.insertOrUpdate(object);
}
});
}
}
Hope this helps!
I've seen an Android project structure in the image below. What does "Bean" mean in this structure? or Why does that folder name "Bean"?
Bean in java is basically a single class encapsulate many objects into a single object and there properties can be manipulated by using getter and setter method.We also call it model class. The below code snippet is an example of bean class.
public class Book implements Serializable{
private String isbn;
private String title;
private String author;
private String publisher;
private int pages;
/**
* Default constructor
*/
public Book() {
this.isbn = "";
this.title = "";
this.author = "";
this.publisher = "";
this.pages = 0;
}
public String getIsbn() {
return isbn;
}
public void setIsbn(final String isbn) {
this.isbn = isbn;
}
public String getTitle() {
return title;
}
public void setTitle(final String title) {
this.title = title;
}
public String getAuthor() {
return author;
}
public void setAuthor(final String author) {
this.author = author;
}
public String getPublisher() {
return publisher;
}
public void setPublisher(final String publisher) {
this.publisher = publisher;
}
public int getPages() {
return pages;
}
public void setPages(final int pages) {
this.pages = pages;
}
}
In your case i think the package you pointed contained all the bean classes
I have a model class "JobPostBean" which I'm initiating in another model class and adding data using the second model class. I would like to clear any data which gets saved in the "JobPostBean" class. Is there any way to clear it either in "JobPostBean" class or in the second model class where its initialised? I would prefer to clear it using a single method rather than setting every item in the "JobPostBean" class to null.

The clear() method removes all the elements of ArrayList .
I am not so new to Android, but started using retrofit today, I was able to clear all errors, now the response body returns null. I know its something to do with the way my class is set up. I have no idea how to handle an array with arrays. Any help would be appreciated. Thanks

Just define a Super class -
public class ResponseDS{

public Product[] products;
}
And use ResponseDS instead of Product class -
#GET("/web-api.php?route=feed/web_api/products")
Call<ResponseDS> loadProducts(#Query("category") Integer id, #Query("key") String apiKey);
Hope it will help :)
