Android Architecture Blueprints is a project to showcase different architectural approaches to developing Android apps. In its different branches you'll find the same app (a TODO app) implemented with small differences.
In this branch you'll find: * Kotlin Coroutines for background operations. * A single-activity architecture, using the Navigation component to manage fragment operations. * A presentation layer that contains a fragment (View) and a ViewModel per screen (or feature). * Reactive UIs using LiveData observables and Data Binding. * A data layer with a repository and two data sources (local using Room and remote) that are queried with one-shot operations (no listeners or data streams). * Two product flavors,
, to ease development and testing (except in the Dagger branch). * A collection of unit, integration and e2e tests, including "shared" tests that can be run on emulator/device or Robolectric.
This project hosts each sample app in separate repository branches. For more information, see the
file in each branch.
| Sample | Description | | ------------- | ------------- | | master | The base for the rest of the branches.
Uses Kotlin, Architecture Components, coroutines, Data Binding, etc. and uses Room as source of truth, with a reactive UI. | | dagger-android
[compare] | A simple Dagger setup that uses
Blueprints v1 had a collection of samples that are not maintained anymore, but can still be useful. See all project branches.
The app in this project aims to be simple enough that you can understand it quickly, but complex enough to showcase difficult design decisions and testing scenarios. For more information, see the app's specification.
To open one of the samples in Android Studio, begin by checking out one of the sample branches, and then open the root directory in Android Studio. The following series of steps illustrate how to open the usecases sample.
Clone the repository:
git clone [email protected]:googlesamples/android-architecture.git
This step checks out the master branch. If you want to change to a different sample:
git checkout usecases
Note: To review a different sample, replace
with the name of sample you want to check out.
Finally open the
directory in Android Studio.
