Android Basics: Amphibians app

https://developer.android.com/codelabs/basic-android-kotlin-training-project-amphibians?continue=https%3A%2F%2Fdeveloper.android.com%2Fcourses%2Fpathways%2Fandroid-basics-kotlin-unit-4-pathway-2%23codelab-https%3A%2F%2Fdeveloper.android.com%2Fcodelabs%2Fbasic-android-kotlin-training-project-amphibians#2

Issue Description:
I've implemented the app per instructions, but upon running the app the connection error drawable is displayed. After doing some logging, I have discovered this is because my retrofit request returns HTTP code 404. Reviewing the instructions, I see the following:

The backend for this API is fairly simple. There are two key pieces of information you'll need to access the amphibians data: a base URL and an endpoint to get the list of amphibians.

Base URL: https://developer.android.com/courses/pathways/android-basics-kotlin-unit-4-pathway-2/
GET amphibians list: android-basics-kotlin-unit-4-pathway-2-project-api.json

I am familiar working with the base URL, passing it into the retrofit builder, but I am not sure what to do with the 'GET amphibians list URI. I know this is needed to resolve my retrofit request successfully, but after reviewing the previous CodeLabs I am not sure how to use this information in my AmphibianApiService.kt file. Surely, this must be passed to retrofit somehow?

Any clarification would be greatly appreciated.

I've currently based my implementation of AmphibianApiService.kt file off of the MarsApiService.kt file from the previous CodeLab:

// Create a property for the base URL provided in the codelab
private const val BASE_URL = "https://developer.android.com/courses/pathways/android-basics-kotlin-unit-4-pathway-2/"

// Build the Moshi object with Kotlin adapter factory that Retrofit will be using to parse JSON
private val moshi = Moshi.Builder()
    .add(KotlinJsonAdapterFactory())
    .build()

// Build a Retrofit object with the Moshi converter
private val retrofit = Retrofit.Builder()
    .addConverterFactory(MoshiConverterFactory.create(moshi))
    .baseUrl(BASE_URL)
    .build()

interface AmphibianApiService {
    // Declare a suspended function to get the list of amphibians
    @GET("amphibians")
    suspend fun getAmphibians(): List<Amphibian>
}

// Create an object that provides a lazy-initialized retrofit service
object amphibianAPI {
    val retrofitService: AmphibianApiService by lazy {
        retrofit.create(AmphibianApiService::class.java)
    }
}

When I use Base URL: https://developer.android.com/courses/pathways/android-basics-kotlin-unit-4-pathway-2/ for retrofit (which is provided in the codelab) , I get 404. I can hit the json directly though (https://developer.android.com/courses/pathways/android-basics-kotlin-unit-4-pathway-2/android-basics-kotlin-unit-4-pathway-2-project-api.json). I'll double check my code to see what's up

Solved All Issues

I fixed all the errors I encountered and put them on another repository of mine because the project was created on a different version of Android Studio that doesn't go along with the version I have now and since the Google training team is no longer maintaining this course and will mark it as deprecated by Dec 2023, I had no option except to create another repository. So here is my repository

Happy coding!

Task - Project Amphibians

Describe the problem
The dependencies and build of the starter code is not up to date causing problems for the app to even run for the first time. I have tried updating the dependencies and plugins from another Project but could not solve the problem.

Steps to reproduce?

1. Go to Android Studio
2. Click on Run
3. See error

Very hard to complete when the people writing this stuff never respond.

Android Basics: Amphibians app-----ViewModelCode does not even exist!

in Get Started section, you are telling me to launch a coroutine using ViewModelScope, yet when I do it, it is red and I can't import it.

How am I supposed to do it then?

2 screen shots below....

Android Basics: Amphibians app--------Error in GENERATED SOURCE FILE

there is a error in DataBinderMapperImpL

Nothing was touched. It says these files should not be edited, yet you guys have a error in it. How can it be fixed if it can't be edited from a mistake you guys made when you built it?

it is the first line underlined in red.

PLEASE TELL ME HOW TO FIX IT.

Bad Test instruction in course

Android Basics: Amphibians app , can not call the getAmphibianList() method

In update the UI from the ViewModel , step 1 , we can not call the getAmphibianList() method from the ViewModel in AmphibianListFragment because it is a private method , it's better to add init {getAmphibianList()} in the AmphibianViewModel

Testing instructions are not related to amphibians application.

Instructions in codelab is incomplete, fortunately i was able to search the solution code, but this made unnecessary confusion.
