Create Android app in Google Play Console
Before you can upload your app to the Google Play Store you need to create an app in the Google Play console.
To upload your app on the Google Play Store, you need to log in using an existing Google account. If you don't have one, create an account by clicking on the "Create account" button. Once logged in, choose to create a developer account for personal or organizational use and provide contact information. Agree to the terms and complete the registration process. You'll be redirected to Google's Developer Console and receive an email from Google to verify your identity, which requires uploading a copy of your ID. Verification may take a few days.
To manually submit your Android app to the Google Play Store using the .AAB file, follow these steps. Open the Google Play Developer Console, and create a new app record by clicking the "Create app" button. Enter the name of your app, select the default language, and indicate if it is free or paid. Check the available declarations and click "Create app" to continue. Next, navigate to the "Set up your app" section and click "View tasks" to complete the required settings.
Once you've completed the initial setup, the dashboard will display a list of tasks to publish your app on Google Play. Click "Create new release" to upload the AAB file, and enter release notes before saving changes. Review the new version and click "Start rollout to Production" to release the app on the Google Play Store.
