I would like to try Android's App Bundle feature.
However, when I would like to make my own app bundle, I cannot because there is no such menu option in my Android Studio, see pic below.
The official youtube video about this topic shows the following:
I have also added android.enableAapt2=true to my gradle.properties file, just as the official sources say, also restarted Gradle daemon, also restarted Android Studio:
Note: Android Studio requires AAPT2 to build app bundles, which is enabled for new projects by default. However, to make sure it is enabled on existing projects, include android.enableAapt2=true in your gradle.properties file and restart the Gradle daemon by running ./gradlew --stop from the command line.
What am I doing wrong?
Where is the missing menu option?
The feature is currently available in the canary and beta channels, but not the stable channel. Try downloading the best version.
You need to download the preview version of Android Studio (v3.2) https://developer.android.com/studio/preview/
After install this version, open your project and will appear a prompt to update the version of gradle.
go to this location in Android studio File > Project Structure > Project Settings > Facets
