App info

To publish your app on Android, you'll need to add an app icon, a name, a package name and an app version. To find the App settings, click on the App Icon on the top left.

For recommendations on your app icon and name, please see this guide.

The Package Name

Each Android app that is published to the Play Store has a unique package name. Currently, you can enter this in the App (Bundle) ID field.

Your app's package name is unique to your app. We recommend reversing your domain name to create your package name i.e. com.yourDomainName.yourAppName to avoid conflicts with other apps.

You can find your package name in your Project Settings under App (Bundle) ID.

Your package name should be all lower case. None of the segments should begin with a number. None of the segments should have an accent on the characters.

Build and Version Number

Before you download your app, make sure you set the appropriate Build and Version Number. Google Play requires each new version of your app to have a unique and sequentially higher Build and Version Number. You can also let Thunkable auto-increment (or automatically increase) the build and version numbers for you.

Download your AAB file

You can download your AAB file by clicking Publish > Publish Android

You will see a dialog asking you to enter your email address. An AAB file will be sent to you:

Publish Your App on Google Play

You will be asked which countries and regions you want your app to be available in.

Then you will be asked to create a new release.

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.

Upload your AAB file

Upload your AAB file in the App Bundles and APKs section. This may take a few minutes.

Add a privacy policy

Congrats! You are now ready to submit to the 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 / Private 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. Copied apps within an account (using the Make Copy) will keep the same keystore as the original app. Apps that are copied from a Share copy link will not have the same keystore.

Exporting / importing a keystore to your app

Export keystore from Thunkable

If you make a copy of a Thunkable app project, the copy will have a different keystore to the original project.

To export a keystore from a Thunkable app project, Click the name and icon of your app in upper left corner to bring up App Settings on right side as seen in 'Import keystore to Thunkable X'. Scroll all the way to the bottom of the App Settings and click Export Keystore.

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.

Click OK to save the .keystore file to your computer.

Note: A Thunkable app 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

Import keystore to Thunkable

Select the the app that you are trying to publish as an update to the Google Play Store.

Click the name and icon of your app in upper left corner to bring up App Settings on right side.

Scroll all the way to the bottom of App Settings and click Import Keystore. Note this will replace the existing keystore for this app so be sure you haven’t used it to publish to Google Play store before proceeding. You can always Export it first and save it to your computer just in case.

Enter the password and select the .keystore file you previously saved to your computer.

Congrats! You should be able to successfully publish updates now. Note that you’ll need to repeat the steps every time you want to update an app that was originally built as a different project as every app has their own keystore.

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:

1. Scroll down to “Release” and click on “Setup”

2. Then “Advanced Settings”.

3. Click the “Unpublished” radio button

4. Then click “Save” to unpublish your app.

You can see the relevant areas below:

Removing your app from the Play Store will not delete it from devices which have previously downloaded the app.
