This is my first android project (I'm a php developer) but i'm struggling to see how to take this example which uses a nested structure under data for the json array whereas my data is not double nested like this example.
The excample code I am trying to modify is from here https://github.com/datanapps/RetrofitKotlin and the key differences in the json are todo with the nesting.
Original
{
"page": 1,
"per_page": 6,
"total": 12,
"total_pages": 2,
"data": [
{
"id": 1,
"email": "george.bluth#reqres.in",

"first_name": "James",
"last_name": "Smith",

}
whereas mine is simply

You "return type" of "method" in Retrofit "interface" will be:
List<MyModel>
And MyModel:
data class MyModel(val _id:String, val device:String,...)
I have the following JSON code for my adaptive card:
{
"type": "AdaptiveCard",

"type": "TextBlock",

"wrap": true,

}
]
},
{
"type": "TextBlock",
"text": "Let's add some tags and notes to make it more memorable",
"wrap": true
},
{
"type": "Input.ChoiceSet",

{
"title": "Work",

But for some reason it doesn't care for the wrap attribute in Android (iOS is working ok). The MS Teams is refusing my submission because of the horizontal scrollbar, how can I solve this?
iOS
Android
Update:
Tested on:
Xiaomi Redmi Note 8
Android version 11 rkq1.201004.002
Teams version 1416/1.0.0.2021163901/1022
The issue is fixed now. Please update your Teams version and check
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()
}

There is a many to many relationship between users and groups.
I am using retrofit with the GsonConverterFactory. On response, how can I parse this information into objects?
I tried making a User class , and a group class, then I put an array of groups as a member of the user class.
But when I access User.getGroups().get(1).getID , it returns 0.
However, User.getGroups().size() does return 4 (the correct number in this case)
How can I achieve this in retrofit?
A practical tool to parse JSON correctly with retrofit can be to generate the classes with http://www.jsonschema2pojo.org
You just have to put the example JSON, the resource type in JSON and put the desired annotation style (GSON, Jackson, ..).
