# Android Sunflower with Compose

A gardening app illustrating Android development best practices with migrating
a View-based app to Jetpack Compose.

This sample showcases:
* Compose working in an existing app: including integration with strings, resources, and themes and styles.
* Integration with an existing architecture based on Jetpack libraries.
* `CollapsingToolbarLayout` behavior implemented manually with Compose.
* Showing [Snackbars](https://material.io/components/snackbars) with Compose.
* Using Compose within a `RecyclerView`

**Note**: To see the original View implementation of Sunflower, checkout the [`views`](https://github.com/android/sunflower/tree/views) branch.

## Features

Sunflower's [plant details screen](app/src/main/java/com/google/samples/apps/sunflower/PlantDetailFragment.kt)
is built with Compose as well as the [plant list item](app/src/main/java/com/google/samples/apps/sunflower/compose/plantlist/PlantListItemView.kt)
view within a `RecyclerView`.

All Compose code can be found in the `compose`
[folder](app/src/main/java/com/google/samples/apps/sunflower/compose).

**Note**: As Compose cannot render HTML code in `Text` yet. The 
`AndroidViewBinding` API is used to embed a `TextView` in Compose. See the 
`PlantDescription` composable in the
[PlantDetailView file](app/src/main/java/com/google/samples/apps/sunflower/compose/plantdetail/PlantDetailView.kt).

## Requirements

### Unsplash API key

Sunflower uses the [Unsplash API](https://unsplash.com/developers) to load pictures on the gallery
screen. To use the API, you will need to obtain a free developer API key. See the
[Unsplash API Documentation](https://unsplash.com/documentation) for instructions.

Once you have the key, add this line to the `gradle.properties` file, either in your user home
directory (usually `~/.gradle/gradle.properties` on Linux and Mac) or in the project's root folder:

```
unsplash_access_key=<your Unsplash access key>
```

The app is still usable without an API key, though you won't be able to navigate to the gallery screen.

Android Studio IDE setup
------------------------
For development, the latest version of Android Studio is required. The latest version can be
downloaded from [here](https://developer.android.com/studio/).

Sunflower uses [ktlint](https://ktlint.github.io/) to enforce Kotlin coding styles.
Here's how to configure it for use with Android Studio (instructions adapted
from the ktlint [README](https://github.com/shyiko/ktlint/blob/master/README.md)):

- Close Android Studio if it's open

- Download ktlint using these [installation instructions](https://github.com/pinterest/ktlint/blob/master/README.md#installation)

- Apply ktlint settings to Android Studio using these [instructions](https://github.com/pinterest/ktlint/blob/master/README.md#-with-intellij-idea)

- Start Android Studio

Non-Goals
---------
Previously, this sample app was focused on demonstrating best practices for
multiple Jetpack libraries. However, this is no longer the case and development
will instead be focused on how to adopt Compose in an existing View-based app.
So, there are no plans to implement features outside of this scope. Keep this
in mind when making contributions to this library.
