Publishing your app to the Play Store is a relatively straightforward process and will help your app reach 2 billion active Android devices.

To publish your app on Android, you'll need to add an
app icon, 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.
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.
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.
Next, create a new release. This is where you'll upload the latest version of your app (.apk)
To complete your Play Store listing, you will have to fill out a content rating questionnaire and set pricing and availability. In addition you will need to add a minimum of 4 design assets - two screenshots, a higher resolution icon (512 x 512 px) and a feature graphic (1024 x 500 px) that shows up on the Play Store app.
Congrats! You are now ready to submit to the Play Store.
If you updating an existing app on the Google Play Store, your app 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
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.
If you make a copy of a Thunkable X app project, the copy will have a different keystore to the original project.
To export a keystore from a Thunkable X 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 X 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
On the Thunkable Cross Platform (x.thunkable.com), 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.
Go to Thunkable Classic (app.thunkable.com) click Apps (in the upper left corner) and then Export keystore to save your Classic
android.keystore file to your computer.
The password for this .keystore file will be android.
