advanced patterns When Parsing Nested JSON with Gson in Android
I've searched everywhere and can't find a clear answer. This might be a silly question, but I'm working on an Android application using Gson for JSON parsing... I have a nested JSON structure that I'm trying to deserialize into a set of data classes. However, I'm working with unexpected behavior where certain fields are not being populated correctly, and I'm not sure why. Here’s the JSON structure I'm dealing with: ```json { "user": { "id": "123", "name": "John Doe", "address": { "street": "123 Main St", "city": "Anytown" } } } ``` And here are the Kotlin data classes I've defined: ```kotlin data class User( val id: String, val name: String, val address: Address ) data class Address( val street: String, val city: String ) ``` I’m trying to parse the JSON into a `User` object like this: ```kotlin val jsonString = // your JSON string here val user = Gson().fromJson(jsonString, User::class.java) ``` However, when I print `user`, the `address` field is populated but the `city` field is empty. The output looks like this: ```plaintext User(id=123, name=John Doe, address=Address(street=123 Main St, city=)) ``` I’ve verified that the JSON structure matches my data classes and also tried adding `@SerializedName` annotations to explicitly name the fields, but that didn’t help. Could there be something I’m missing in the parsing process? Is it possible that Gson is having issues with parsing nested objects in my case? Any insights would be appreciated! What's the best practice here? I'm developing on Debian with Kotlin. Has anyone dealt with something similar?
