Overview

Android Sunflower

A gardening app illustrating Android development best practices with Android Jetpack.

Android Sunflower is currently under heavy development. Note that some changes (such as database schema modifications) are not backwards compatible and may cause the app to crash. In this case, please uninstall and re-install the app.

Introduction

Android Jetpack is a set of components, tools and guidance to make great Android apps. They bring together the existing Support Library and Architecture Components and arrange them into four categories:

Android Sunflower demonstrates utilizing these components to create a simple gardening app. Read the Introducing Android Sunflower article for a walkthrough of the app.

Getting Started

This project uses the Gradle build system. To build this project, use the gradlew build command or use "Import Project" in Android Studio.

There are two Gradle tasks for testing the project:

connectedAndroidTest - for running Espresso on a connected device
test - for running unit tests

For more resources on learning Android development, visit the Developer Guides at developer.android.com.

Unsplash API key

Sunflower uses the Unsplash API 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 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.

Libraries Used

Foundation - Components for core system capabilities, Kotlin extensions and support for multidex and automated testing.
- AppCompat - Degrade gracefully on older versions of Android.
- Android KTX - Write more concise, idiomatic Kotlin code.
- Test - An Android testing framework for unit and runtime UI tests.
Architecture - A collection of libraries that help you design robust, testable, and maintainable apps. Start with classes for managing your UI component lifecycle and handling data persistence.
- Data Binding - Declaratively bind observable data to UI elements.
- Lifecycles - Create a UI that automatically responds to lifecycle events.
- LiveData - Build data objects that notify views when the underlying database changes.
- Navigation - Handle everything needed for in-app navigation.
- Room - Access your app's SQLite database with in-app objects and compile-time checks.
- ViewModel - Store UI-related data that isn't destroyed on app rotations. Easily schedule asynchronous tasks for optimal execution.
- WorkManager - Manage your Android background jobs.
UI - Details on why and how to use UI Components in your apps - together or separate
- Animations & Transitions - Move widgets and transition between screens.
- Fragment - A basic unit of composable UI.
- Layout - Lay out widgets using different algorithms.
Third party and miscellaneous libraries
- Glide for image loading
- Hilt: for dependency injection
- Kotlin Coroutines for managing background threads with simplified code and reducing needs for callbacks

Upcoming features

Updates will include incorporating additional Jetpack components and updating existing components as the component libraries evolve.

Interested in seeing a particular feature of the Android Framework or Jetpack implemented in this app? Please open a new issue.

Android Studio IDE setup

For development, the latest version of Android Studio is required. The latest version can be downloaded from here.

Sunflower uses ktlint to enforce Kotlin coding styles. Here's how to configure it for use with Android Studio (instructions adapted from the ktlint README):

Close Android Studio if it's open
Download ktlint using these installation instructions
Apply ktlint settings to Android Studio using these instructions
Start Android Studio

Non-Goals

The focus of this project is on Android Jetpack and the Android framework. Thus, there are no immediate plans to implement features outside of this scope.

Comments

Detail page has two toolbars

After converting to single-activity, there're two toolbars on detail screen. The app needs a ux/ui decision what should be shown in detail page. @tiembo

Navigation component crashes.
I guess this is just broken Navigation, and i'm going to post this issue at Navigation bug tracker but still.

Open Plant list screen

With 2 or more fingers tap different Plant items at the same time

You will get exception

java.lang.IllegalArgumentException: navigation destination com.google.samples.apps.sunflower:id/action_plant_list_fragment_to_plant_detail_fragment is unknown to this NavController

Seems like after first click Navigation framework thinks you are already at Plant detail part of the nav graph. And this fragment can't use this action. It seems just broken as for me. I'd like it opens two separate screens if you do things like this. This probably will crash you app everywhere when you can navigate with more then 1 then click listener (for example 2 buttons to register/forgot password screens)

In the current situation i have found few workarounds with this problem:

We can wrap it.findNavController().navigate(direction) with tryCatch block, catch IllegalArgumentException and do nothing. But it seems just broken, don't forget to leave a commentary in that catch block

You can use Global actions only https://developer.android.com/topic/libraries/architecture/navigation/navigation-global-action But this is again will look just horrible tho. This seems acceptable if we add search into the app

You can add to PlantDetailFragment in nav graph action to navigate to itself (recursive). This is horrible as well.

Offtopic: if you use recursive destination and tie ActonBar with NavController - check you home/back button. This will be broken if your recursive destination is first in nav graph.

Well, i don't have the good looking solution for the issue quite yet. Still working

Fix #132: the PlantAndGardenPlantingsViewModel decoupled from context and string-resource
This bug is critical and obscure, there's already issue on Google, see also:

https://github.com/googlesamples/android-sunflower/issues/132

https://issuetracker.google.com/u/2/issues/111961971

@tiembo I think this fix is important for this project which is the official demo to declare how people use the Jetpack, so please check out.

Material Design specs

The sample app UI is quite crude, and parts of it does not follow the MD specs. e.g. the Add icon used in the FAB is using the wrong size e.g. paddings of text

Are there any plans to touch up the UI? or a mock that i can follow for a PR

Compiler Error

Hi, I am pretty new to Kotlin as a development language for Android and I decided to give it a try with this sample app especially since it also introduces me to the Android Jetpack set of libraries and components. I, unfortunately, cannot seem to get it to build once I clone it into my Android Studio. I keep getting the following error and I can't seem to fix it.

AndroidX?
Hello, I was wondering if you guys/gals are going to do a namespace migration to androidx in this project.

I'm asking this because on my current project I'm getting errors:

Failed to resolve: com.google.android.material:material:1.1.0 Failed to resolve: androidx.fragment:fragment:1.1.0 Failed to resolve: androidx.recyclerview:recyclerview:1.1.0 (...)

It would be good to see a working sample with recommended practices. I've been following the guide but with no success, also I included the experimental:

# AndroidX android.enableJetifier=true android.useAndroidX=true

Running on:

Displaying edge-to-edge, but insets not being handled leads to clipping

GardenActivity calls WindowCompat.setDecorFitsSystemWindows(window, false) to display edge-to-edge, but insets are not being taken into account resulting in items being clipped by the navigation bar.

This is especially noticable with the opaque taskbar on Android 12L or Android 13.

Correct PlantDetailViewModelTest testing by Espresso dependency
The below error is shown on the PlantDetailViewModelTest running.

`FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:checkDebugAndroidTestDuplicateClasses'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable Duplicate class org.checkerframework.checker.compilermsgs.qual.CompilerMessageKey found in modules checker-3.1

This is fixed by Gradle changing. Also, remove a duplicate data binding and buildFeatures.
