In order to reduce app size and deliver sceneform dependencies to limited set of devices and users who want to use it. This is an attempt to bundle sceneform as a seperate on demand dynamic module using Android feature delivery which is delivered through App Bundles.
The application consists of primary app module and sceneform_dynamic_module. When the user clicks on Start Sceneform Activity, app attempts to download the sceneform dependency and launch an AR fragment.
Steps to load app bundle and test apk locally:
- Step1: Download bundletool from here. Rename the jar to
bundletool-all.jar - Step2: Open terminal and change current working directory to the one containing the above jar. Run the below command:
alias bundletool='java -jar bundletool-all.jar' - Step 3: Generate App Bundle
./gradlew :app:bundleDebug - Step 4: Run bundletool to generate apks
bundletool build-apks --local-testing --bundle app-debug.aab --output app-debug.apks - Step 5: Connect device and install apks
bundletool install-apks --apks app-debug.apks
Currently, getting below error when trying to launch the Sceneform Activity:
