Creating an issue-based app for Android

Twixl Support Team Updated: - Created :

Use the build settings wizard to go through the process step by step

When creating an app build for the first time, a configuration wizard will walk you through the different steps and options of the build process. Once you saved that setting, you will be able to re-use it later for generating an update of that app.

Below is an overview of the different steps involved for creating an issue-based Android app.

1. Choose a name for your setting

Usually the build setting name will refer to the publication name.

Choose a name for your setting
2. App type

Here you can select the type of app you wish to build:

App Store Kiosk

App Store Kiosk

This will generate a kiosk app that will essentially be an empty shell.

3. General Settings

3.1. General

Application name

This is the name users will see on the home screen of the device.

Build For

Choose whether you want an app that supports Tablets, Phones, or both.

3.2. UI Languages

Here you can select the languages your app will support - alerts and error messages in your app will then be displayed in the system language specified on the device. 

3.3. App Store Rating

If you want to prompt the reader to rate your app on the app store, you need to check this option.

4. Analytics

For multi-issue apps, the Twixl Distribution Platform will gather an extensive list of analytics data for you automatically.

5. Artwork

5.1. App Icon

The app icon that will be displayed in the Home Screen of the device. Should have a size of 1024x1024 pixels.

5.2. Startup Screens for Tablets

These screens will be displayed while the app is starting up (if you do not select any images, the default ones will be used). They need to have the following dimensions:

  • Android Portrait: 800 x 1280 pixels
  • Android Landscape: 1280 x 800 pixels

5.3. Startup Screens for Phones

These screens will be displayed while the app is starting up (if you do not select any images, the default ones will be used). They need to have the following dimensions:

  • Portrait (4:3): 640 x 960 pixels
  • Portrait (16:9): 1242 x 2208 pixels
  • Landscape (16:9): 2208 x 1242 px
6. Code Signing

Code signing is a security measure to provide proof that you are indeed the publisher of an app.

Android Code Signing

Android Code Signing

This should be a reverse DNS name like com.yourdomain.yourpublication - if you are going to be creating an app for both the iPad and Android, the best practice is to use the same one as the one you used for the iPad.

7. App Store Kiosk Settings

Before you can enter the details below, you will need to go through the process of adding an app in the Twixl Distribution Platform.

Once you've done that, copy the application key from the platform and enter it here.

Now make sure to add your app in the Google Play Developer Console and select "Services & APIs", then copy the license key for your app, then paste it in the "Android License Key" field.

When you create a build, you will get different options for your build, as shown below:


Allows you to increment the version when you are updating your app


Android - select Test build to create a version for internal testing or Android for Google Play for submitting to the Play store.


As a multi-issue app starts as an empty app, there is no need to select a publication.


Irrelevant for Android.
