Publish to Play Store (Android) with AAB
How to publish your Thunkable project in the Google Play Store
Success on Google Play starts with quality. The best apps and games have higher ratings, more installs, and more engagement. We recommend visiting the Play Store Developer Policy Center before you submit your app to the Play Store.
Publishing to the Google Play Store requires a Google Play Developer Account (approximately $25 USD one-time fee). Don't have an account? Sign up here.
AAB vs APK
When you download an app from Thunkable you receive an email with an APK file that you download directly to your Android device.
When you publish an Android app you receive an email with an AAB file for you to upload to the Google Play Store.

App Name - see here for best practices: App Settings
Icon - see here for best practices: App Settings
Package Name (referred to as App (Bundle) ID in Thunkable)
Package Name
Every new Thunkable project is automatically given a unique App (Bundle) ID. For the purposes of publishing to the Play Store, this is refered to as your app's package name.
To locate your package name:
Open your Thunkable project.
Navigate to the Design tab.
Click the Settings gear icon in the sidebar.
Copy the content of the App (Bundle) ID field. This is your package name.
You'll notice that Thunkable adheres to the following naming convention to avoid conflicts with other apps: com.yourDomainName.yourAppName. It is all lower case letters, none of the segments begin with a number, and there are no characteres with accents.
Android Version
Google Play requires each new version of your app to have a unique and sequentially higher Version Name and Version Code. You can let Thunkable auto-increment (or automatically increase) the version data for you.
Download your Android App Bundle (AAB) file
The Apple and Android publishing processes are quite different. To publish with Apple, you complete the process in the Thunkable publishing wizard and the app file is sent directly to your Apple TestFlight. To publish with Android, you receive an email from Thunkable with your app's AAB file, which you download and then upload to the Google Play Store.
An AAB file cannot be installed on an Android device. If you want to download and install your project, please read the Download docs.
To download your Android App Bundle (AAB) file:
Within your Thunkable project, click the Publish and Download icon.
A publishing modal is provided to guide you through the publication process.
Enter the email address you want the app download link sent to.
Click Send.
In approximately 30 minutes, you will receive your AAB file to the email address you provided.
When you receive the email, download the AAB file to your computer. Note: If you use Google Chrome, your browser settings may prevent you from downloading your AAB file. Simply open the email in Firefox or Safari to download your AAB file.

Prepare
Google will offer to protect your app signing key. You can click Continue to allow this to proceed. You will only be asked this the first time you publish a release.
See Manage Your Own App Signing below if you do not want Google to manage your app signing.
If you have a newly created personal Google developer account, you must run a closed test for your app with a minimum of 20 testers who have been opted-in for at least the last 14 days continuously. When you meet these criteria, you can apply for production access on the Dashboard. You can learn more here.
You can share your app for free in the Thunkable community and find people to test it.
Click Start Rollout to Production to publish your app!
Once your app has been reviewed, it will go live on the Google Play Store.
Updating an existing app on the Play Store
You can view Google's instructions for updating your app here. Please refer to the content that references app bundles, not APK files.
If you are updating an existing app on the Google Play Store, your Thunkable project will need to have:
the same package name as the published app
an incremented version number (version number is higher than the version number of your published app)
the same keystore as the published app
You will need need to change any app signing settings when updating a published app.
The Keystore / Signing Key
Keystores in Android are storage mechanisms for security certificates to prevent others from updating your app on the Google Play store. Your keystore contains a private key that is unique to your app.
Duplicated apps within an account (Duplicate Your Project) maintain the same keystore as the original app. Apps copied from a Share link do not have the same keystore.
You must save your Android keystore and password somewhere safe. Google will not provide it for you if you lose it.
If your app was deleted, and you have not downloaded a copy of your keystore, it is permanently lost. We strongly recommend you use Google's App Signing Service so that you can update your published apps if your keystore is lost.
Exporting / importing a keystore to your app
Export keystore from a Thunkable project
A Thunkable project will not have a keystore until either a keystore is imported or the project is downloaded as an Android app for the first time.
If you make a copy of a Thunkable project, the copy will have a different keystore to the original project.
To export a keystore from a Thunkable project:
Click the gear icon of on the left hand side of your Design tab your app in upper left corner to bring up App Settings
Scroll to Android Keystore and click Export Keystore
Alias and Password
In the dialog that comes up, you will see the keystore's password and a button that says Export Keystore. You will need this password to import your keystore to other projects. You can change the password at this stage by editing the password in the text box.
The default keystore alias used by Thunkable will be AndroidKey.
Click OK to save the .keystore file to your computer.
Import keystore to Thunkable
Importing a keystore to a Thunkable project will override its existing keystore. Make sure you don't need this project's keystore to publish an update to your app before continuing!
To import a keystore to a Thunkable project:
Click the gear icon of on the left hand side of your Design tab your app in upper left corner to bring up App Settings
Scroll to Android Keystore and click Import Keystore
Enter the password and select the .keystore file you previously saved to your computer into the Import Keystore dialog.
Remove your app from the Play Store
To make your app unavailable for download on the Play Store, open your app listing on the Google Play Console and do the following:
Scroll down to “Release” and click on “Setup”
Then “Advanced Settings”.
Click the “Unpublished” radio button
Then click “Save” to unpublish your app.
You can see the relevant areas below:

Manage Your Own App Signing
If you don't want Google to manage your App Signing, you can do so yourself. This is not necessary.
In Thunkable:
Download your Keystore Zip
You will need to download your Keystore Zip. This is a compressed version of your app's Android Keystore.
You can download this from your project settings under Keystore Zip:
We recommend creating a new folder on your computer. Download your AAB file and your Keystore Zip to this new folder. That way, the correct AAB file and Keystore Zip will be together.
In the Play Store:
Click Manage App Signing:
Click Export and upload a key from Java keystore:
You can skip straight to Step 3: Upload generated ZIP and Upload the Keystore ZIP you downloaded from your project settings.
Click Continue.
Continue following the instructions in this document from Upload your AAB file.
