Android Room Write Custom Nested Objects

Android Room Write Custom Nested Objects - android

Okay so I've successfully sent GET request to a server using Retrofit library, and parsed that data in my app. Now I want to store that data(custom model classes which I have created) in ROOM database, however I have a lot of model classes. So what's the best way to write that custom objects in database, how should I write type converters for this? Check my network response to understand how complex the data is:

Although there's no best way of handling this, besides having to create converters models for each of these fields, it would be wise to limit the amount of data you're saving to only the relevant information that you're going to need and then to use custom converters to convert your data automatically.
As requested by OP in the comments, here's a basic example of how you can add a type converter for a list/array (making use of Gson):
extension methods:
fun <T> String.fromGson(classOfT: Class<T>) = Gson().fromJson(this, classOfT)
fun Any.toGson() = Gson().toJson(this)
converter:
class MyConverter {
#TypeConverter
fun toListOfObjects(value: String?): List<Foo> {
if (value.isNullOrEmpty()) {
return emptyList()
}
val jsonArray = value.fromGson(JsonArray::class.java)
return jsonArray.map { jsonArray -> jsonArray.fromGson(Foo::class.java) }
}
#TypeConverter
fun toString(value: List<Foo>?) = value?.toGson()
}

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;
}
}

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;

Json parsing in skyscanner pricing api

I started working with sky-scanner API using volley on Android. I am able to poll the response from the API, however I have no clue how to parse the json which is sent in response, please see json below. The json response is very big, I have never worked with such responses before thus have no idea how can I handle this.
Can someone please help me figure this out? There is no sample implementation done by anyone for skyscanner for android.
JSON response to be parsed to get price, agents, flight number, carrier, duration of flight, image URL of flight.

If you are able to pull the json data then try using this js script:
Make sure to add jQuery
Change the value of the url variable with the session poll url you created

P.S. I hope this will helps you the idea how to get the data you need.

I'll show a basic example of how to parse. Take the following sample JSON.
http://api.androidhive.info/contacts/
How to get the contacts list.
JSONObject jsonObj = new JSONObject("Your JSON String here");
JSONArray contacts = jsonObj.optJSONArray("contacts");
How to calculate the phone number
//Get first contact
JSONObject firstContact = contacts.optJSONObject(0);
JSONObject phone = firstContact.optJSONObject("phone");
String mobileNo = phone.optString("mobile");
Similarly you can apply this technique to your JSON.

missing fields in profile from LinkedIn Android SDK

I'm using the LinkedIn Android SDK downloaded from here (version 1.1.4) and have set up authentication already like this:
liSessionManager.init(activity,
Scope.build(Scope.R_BASICPROFILE, Scope.R_EMAILADDRESS), authListener);
and everything works fine, but when I want to get the profile data, returned json is missing fields like summary in job positions and general summary for the given profile.
The request is made like this:
apiHelper.getRequest(activity, GET_LINKED_IN_PROFILE_URL, apiListener);
where GET_LINKED_IN_PROFILE_URL is https://api.linkedin.com/v1/people/~:(id,first-name,last-name,email-address,formatted-name,headline,location,industry,current-share,num-connections,num-connections-capped,summary,specialties,positions,phone-numbers,public-profile-url,picture-url,picture-urls::(original))?format=json.
The response is as follows:

Which shows that the Android SDK's response is missing some job positions and a summary for a profile.

It turned out LinkedIn is not returning fields that have no value. If you don't setup a summary in your profile, then there won't be a field named summary in the response. (Don't expect anything like "summary" : null)
Additionally only first position is returned for a given profile while using r_basicprofile scope. It's confusing since this one profile is returned in the positions array.
based on https://developer.linkedin.com/docs/fields/basic-profile :
Positions - An object representing the member's current position.
See Position Fields for a description of the fields available within this object.
The reason why the API Console's response was having all job positions is because it asked for r_fullprofile scope while authenticating

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
public List<FieldMeta> getFields() {
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.
