Now in Android App
|
||||
==================
|
||||
|
||||
**Learn how this app was designed and built in the [design case study](https://goo.gle/nia-figma), [architecture learning journey](docs/ArchitectureLearningJourney.md) and [modularization learning journey](docs/ModularizationLearningJourney.md).**
|
||||
|
||||
This is the repository for the [Now in Android](https://developer.android.com/series/now-in-android)
|
||||
app. It is a **work in progress** 🚧.
|
||||
|
||||
**Now in Android** is a fully functional Android app built entirely with Kotlin and Jetpack Compose. It
|
||||
follows Android design and development best practices and is intended to be a useful reference
|
||||
for developers. As a running app, it's intended to help developers keep up-to-date with the world
|
||||
of Android development by providing regular news updates.
|
||||
|
||||
The app is currently in development. The `demoRelease` variant is [available on the Play Store in open beta](https://play.google.com/store/apps/details?id=com.google.samples.apps.nowinandroid).
|
||||
|
||||
# Features
|
||||
|
||||
**Now in Android** displays content from the
|
||||
[Now in Android](https://developer.android.com/series/now-in-android) series. Users can browse for
|
||||
links to recent videos, articles and other content. Users can also follow topics they are interested
|
||||
in.

||||
# Development Environment
|
||||
|
||||
**Now in Android** uses the Gradle build system and can be imported directly into Android Studio (make sure you are using the latest stable version available [here](https://developer.android.com/studio)).
|
||||
|
||||
Change the run configuration to `app`.
|
||||
|
||||
|
||||
|
||||
The `demoDebug` and `demoRelease` build variants can be built and run (the `prod` variants use a backend server which is not currently publicly available).
|
||||
|
||||
|
||||
|
||||
Once you're up and running, you can refer to the learning journeys below to get a better
|
||||
understanding of which libraries and tools are being used, the reasoning behind the approaches to
|
||||
UI, testing, architecture and more, and how all of these different pieces of the project fit
|
||||
together to create a complete app.
|
||||
|
||||
NOTE: Building the app using an M1 Mac will require the use of
|
||||
[Rosetta](https://support.apple.com/en-gb/HT211861). See
|
||||
[the following bug](https://github.com/protocolbuffers/protobuf/issues/9397#issuecomment-1086138036)
|
||||
for more details.
|
||||
|
||||
# Architecture
|
||||
|
||||
The **Now in Android** app follows the
|
||||
[official architecture guidance](https://developer.android.com/topic/architecture)
|
||||
and is described in detail in the
|
||||
[architecture learning journey](docs/ArchitectureLearningJourney.md).
|
||||
|
||||
# Modularization
|
||||
|
||||
The **Now in Android** app has been fully modularized and you can find the detailed guidance and
|
||||
description of the modularization strategy used in
|
||||
[modularization learning journey](docs/ModularizationLearningJourney.md).
|
||||
|
||||
# Build
|
||||
|
||||
The app contains the usual `debug` and `release` build variants.
|
||||
|
||||
In addition, the `benchmark` variant of `app` is used to test startup performance and generate a
|
||||
baseline profile (see below for more information).
|
||||
|
||||
`app-nia-catalog` is a standalone app that displays the list of components that are stylized for
|
||||
**Now in Android**.
|
||||
|
||||
The app also uses
|
||||
[product flavors](https://developer.android.com/studio/build/build-variants#product-flavors) to
|
||||
control where content for the app should be loaded from.
|
||||
|
||||
The `demo` flavor uses static local data to allow immediate building and exploring of the UI.
|
||||
|
||||
The `prod` flavor makes real network calls to a backend server, providing up-to-date content. At
|
||||
this time, there is not a public backend available.
|
||||
|
||||
For normal development use the `demoDebug` variant. For UI performance testing use the
|
||||
`demoRelease` variant.
|
||||
|
||||
# Testing
|
||||
|
||||
To facilitate testing of components, **Now in Android** uses dependency injection with
|
||||
[Hilt](https://developer.android.com/training/dependency-injection/hilt-android).
|
||||
|
||||
Most data layer components are defined as interfaces.
|
||||
Then, concrete implementations (with various dependencies) are bound to provide those interfaces to
|
||||
other components in the app.
|
||||
In tests, **Now in Android** notably does _not_ use any mocking libraries.
|
||||
Instead, the production implementations can be replaced with test doubles using Hilt's testing APIs
|
||||
(or via manual constructor injection for `ViewModel` tests).
|
||||
|
||||
These test doubles implement the same interface as the production implementations and generally
|
||||
provide a simplified (but still realistic) implementation with additional testing hooks.
|
||||
This results in less brittle tests that may exercise more production code, instead of just verifying
|
||||
specific calls against mocks.
|
||||
|
||||
Examples:
|
||||
- In instrumentation tests, a temporary folder is used to store the user's preferences, which is
|
||||
wiped after each test.
|
||||
This allows using the real `DataStore` and exercising all related code, instead of mocking the
|
||||
flow of data updates.
|
||||
|
||||
- There are `Test` implementations of each repository, which implement the normal, full repository
|
||||
interface and also provide test-only hooks.
|
||||
`ViewModel` tests use these `Test` repositories, and thus can use the test-only hooks to
|
||||
manipulate the state of the `Test` repository and verify the resulting behavior, instead of
|
||||
checking that specific repository methods were called.
|
||||
|
||||
# UI
|
||||
The app was designed using [Material 3 guidelines](https://m3.material.io/). Learn more about the design process and
|
||||
obtain the design files in the [Now in Android Material 3 Case Study](https://goo.gle/nia-figma) (design assets [also available as a PDF](docs/Now-In-Android-Design-File.pdf)).
|
||||
|
||||
The Screens and UI elements are built entirely using [Jetpack Compose](https://developer.android.com/jetpack/compose).
|
||||
|
||||
The app has two themes:
|
||||
|
||||
- Dynamic color - uses colors based on the [user's current color theme](https://material.io/blog/announcing-material-you) (if supported)
|
||||
- Default theme - uses predefined colors when dynamic color is not supported
|
||||
|
||||
Each theme also supports dark mode.
|
||||
|
||||
The app uses adaptive layouts to
|
||||
[support different screen sizes](https://developer.android.com/guide/topics/large-screens/support-different-screen-sizes).
|
||||
|
||||
Find out more about the [UI architecture here](docs/ArchitectureLearningJourney.md#ui-layer).
|
||||
|
||||
# Baseline profiles
|
||||
|
||||
The baseline profile for this app is located at [`app/src/main/baseline-prof.txt`](app/src/main/baseline-prof.txt).
|
||||
It contains rules that enable AOT compilation of the critical user path taken during app launch.
|
||||
For more information on baseline profiles, read [this document](https://developer.android.com/studio/profile/baselineprofiles).
|
||||
|
||||
> Note: The baseline profile needs to be re-generated for release builds that touch code which changes app startup.
|
||||
|
||||
To generate the baseline profile, select the `benchmark` build variant and run the
|
||||
`BaselineProfileGenerator` benchmark test on an AOSP Android Emulator.
|
||||
Then copy the resulting baseline profile from the emulator to [`app/src/main/baseline-prof.txt`](app/src/main/baseline-prof.txt).

# Bug report
|
||||
**Affected library:** Coil Compose
|
||||
**Cause:** Coroutine Launched Outside Side Effect in rememberAsyncImagePainter
|
||||
|
||||
I have identified a bug in the Coil Compose library that appears to originate from the
|
||||
rememberAsyncImagePainter composable function. The bug arises when a onRemembered function is
|
||||
invoked inside the rememberAsyncImagePainter function.
|
||||
|
||||
onRemembered is a non-composable function that establishes a new coroutine scope and launches a
|
||||
coroutine. The issue appears to be that the coroutine is being launched outside of a side effect
|
||||
block within a composable function, which is not a good practice in the Jetpack Compose framework.
|
||||
The main reason why launching coroutines outside a side effect in a composable function is
|
||||
problematic is due to the life-cycle of the composable function. Jetpack Compose recomposes (reruns)
|
||||
composable functions for various reasons, such as when the data they're displaying changes. This
|
||||
means that a coroutine could be launched multiple times if it's not managed within a side effect
|
||||
block such as LaunchedEffect, DisposableEffect, or produceState.
|
||||
|
||||
Launching a coroutine outside a side-effect block can also result in memory leaks as it's not tied
|
||||
to the lifecycle of the composable function. Side effects ensure that when the composable leaves the
|
||||
composition, any resources (like the coroutine) are cleaned up.
|
||||
|
||||
This could lead to unexpected behavior, as the scope of the coroutine isn't necessarily tied to the
|
||||
lifecycle of the composable function, which can result in unexpected outcomes such as memory leaks
|
||||
or even application crashes.
|
||||
|
||||
Potential Solution:
|
||||
A potential solution could be to move the coroutine launch into a side effect block such as
|
||||
LaunchedEffect that automatically cancels the coroutine when the composable function leaves the
|
||||
composition.
|
||||
|
||||
```
|
||||
java.lang.IllegalStateException: Unsupported concurrent change during composition. A state object was modified by composition as well as being modified outside composition.
