@Gunndarr Dotter I finally published my Volt MX application to the Google Play Store. For sure, it has been a roller-coaster ride for me. From having many roadblocks in generating the aab file for the application in Volt MX to fulfilling the requirements in the Play Store, I covered a lot and learnt too!
Thanks for helping me out! By the way, the link to my application is: Wishy - Google Play
To finally mark this question as answered, I am finally providing the steps that might help others to get their AAB/APK for their applications (this is for Android applications only):
To build the apk/aab, you need to have Android Studio, JDK (v11) and Bundletool installed on your local machine.
Step1 (Installing Android Studio): You can download the same from: https://developer.android.com/studio
Step 2 (Installing JDK v11): Java and JDK are two different things and you must have JDK v11 installed on your local machine because as of now this is the version that is supported by Volt MX.
Download link: https://www.oracle.com/in/java/technologies/javase/jdk11-archive-downloads.html
Note: You would have to create an account on the Oracle website to download the archived versions.
Step 3 (Installing Bundletool): Download the bundletool.jar file via this page: https://github.com/google/bundletool/releases
Then you have to provide the destinations for each three of them in the Preferences so that the aab/apk files can be built and saved on your local machine.
Step 4 (Choose what to build): Click on the Project Settings (⚙️) and move to the Android Mobile inside the Native settings. In there, you have to choose the Build Format (aab/apk) file. Based on your selection here, your output file will be provided.
Step 5 (Build the final thing): Click on the Build section in the navbar and then Build Native Local (Ctrl+N). Below is the snippet for the same:
After following the above instructions, you will be able to build the aab/apk file successfully :) I hope this helps you in any manner.
