Dependency Injection in Compose
OverviewDependency injection is a programming pattern which prescribes that classes do not construct instances of their dependencies, instead such instances are provided. This pattern enables separation of concerns, and increases testability, reusability, and ease of maintenance. See Dependency injection in Android to review the benefits of dependency injection and its core concepts. You may alrea
Effective state management for TextField in Compose
TL;DR To prevent synchronization issues and unexpected behaviors: – Avoid delays/asynchronous behaviors between typing and updating TextField state. – Avoid holding TextField state using a reactive stream (e.g. collecting from StateFlow using the default dispatcher) – Define TextField state variables with Compose APIs like MutableState<String>.Hoist TextField state to the ViewModel when needed e.g
When To Use GraphQL Non-Null Fields
Learn what some of the unexpected costs of GraphQL non-null fields are. In the GraphQL type system all types are nullable by default. This means that a type like Int can take any integer (1, 2, etc.) or null which represents the absence of any value. However, the GraphQL type system allows you to make any type non-null which means that the type will never produce a null value. When using a non-nul

In the following posts from our Jetpack DataStore series, we will cover several additional concepts to understand how DataStore interacts with other APIs, so that you’d have everything at your disposal to use it in a production environment. In this post, we will be focusing on Kotlin serialization. We will be referring to the Preferences and Proto codelabs throughout this post, for code samples. D
Migrating from LiveData to Kotlin’s Flow
LiveData was something we needed back in 2017. The observer pattern made our lives easier, but options such as RxJava were too complex for beginners at the time. The Architecture Components team created LiveData: a very opinionated observable data holder class, designed for Android. It was kept simple to make it easy to get started and the recommendation was to use RxJava for more complex reactive
How to Run Android Studio on ANY Device With JetBrains Projector
Android development is resource hungry. In fact, even a top of the line MacBook Pro can barely handle a mid to large project. Compiling and running the app takes a whopping 10 to 15 Gb of RAM that just sits there, and that’s without running an emulator! Needless to say if your laptop has only 16 Gb of RAM, good luck doing anything else while developing. My personal laptop, a 4 year old Razer blade
