PlayCore API sample

This sample demonstrates usage of the PlayCore API.



The sample contains several modules.

app -> Contains the base application which always will be installed on device.

The MainActivity class demonstrates how to use the API to load and launch features.

The BaseSplitActivity abstract class implements the required SplitCompat.Install() call in the attachBaseContext method. This allow to launch an activity from a freshly downloaded dynamic module without having the restart the application.

features/* -> Contains features which can be downloaded on demand using the PlayCore API. instant/* -> Contains instant enabled features which can be downloaded using the PlayCore API or via Url.

Each feature as some distinctly unique characteristics.

features/assets -> Feature containing only assets. features/kotlin -> Feature written in Kotlin. features/java -> Feature written in Java. features/native -> Feature written in Kotlin using JNI. instant/split -> Instant Feature without an URL route. Loaded using Split Install API instant/url -> Instant Feature with a URL route

The AndroidManifest files in each feature show how to declare a feature module as part of a dynamic app. Any module with the instant attribute is instant enabled. In this sample these can be found in the instant/ folder:



Getting Started

Clone this repository, enter the top level directory and run ./gradlew tasks to get an overview of all the tasks available for this project.

Testing dynamic delivery

To test dynamic delivery with this sample, you'll need to upload it to the Google Play Store's internal testing channel.

Before uploading, make sure to change the applicationId in app/build.gradle.

Running instrumentation tests

In order to run instrumentation tests, parallel builds have to be turned off at the moment. This means you can run them via ./gradlew connectedAndroidTest --no-parallel.

Tooling support for this is being worked on – currently it's not possible to run instrumentation tests for dynamic-feature modules from Android Studio directly. Use the command line instead.
