Adapting FirebaseAuth for the new Activity Result API

Activity Result API is a new set of classes that enhances the way we use the recently deprecated methods startActivityForResult and onActivityResult, thats a usual way for interact with another apps using intents and a response code for checking the result data.

In this short post, i'm sharing to you how adapt the firebase auth flow using the Activity Result APIs

Activity Result APIs are available since AndroidX Activity 1.2.0-alpha02 and Fragment 1.3.0-alpha02. Remember to use -ktx artifacts to get additional extensions that helps you write cleaner Kotlin code.

Speaker Rider

by Tatiana Mac

Last updated 14 April 2021

What is a speaker rider?

As speaking comes with immense privilege, I have crafted a speaker rider to set expectations and boundaries around my engagement. I am grateful to all the conference organisers who have brilliantly hosted me. I would love to continue to exercise this privilege to speak at conferences, and use this privilege to make the landscape more accessible and beneficial to tech's most historically excluded and marginalised communities.

Considerations

😫 I provide a lot of explanations for those of you who never had to consider these things. Most thoughtful conferences I've attended check most of these boxes intrinsically, particularly when conference runners are experienced speakers. They get it.

/**
 * Let's say we want to display a list of Animals in a RecyclerView. 
 * The list can contain items of type Dog, Cat and Snake.
 */

// AdapterDelegate for Dog.
fun dogAdapterDelegate(picasso : Picasso) = adapterDelegate<Dog, Animal>(R.layout.item_dog){ // Generics Types means this AdapterDelegate is used if item is instanceof Dog (whole list is List<Anmial>)
   // this block is run once in onCreateViewHolder. Think of it as an intializer for a ViewHolder.
  val name = findViewById(R.id.name)
  val image = findViewById(R.id.image)
