Google Play installation
Below a standard installation process on Android. Your experience may vary depending on the version of Google Play used. The purchase/upgrade screen will look like this:
Sometimes installing an app using Google Play will fail. The device might for example not be able to download the package properly and the installation might fail. If this error occurs, you might need to retry to download the package after purchase. As always, we advise you to check that you have a stable internet connection and use Wifi if you wish to avoid carrier charges.
Until you can see the OPEN app button from within the Google Play app on your device (Step 5 above), the issue is most likely related to Android and you should try Google Play current troubleshooter page. If the Google Play app displays OPEN but the app doesn't work properly, take contact with us.
APK expansion files on Google Play
On Google Play, we've decided to use APK expansion files for the apps that exceed 50M. This means that the app comes in multiple packages and may require additional downloads at first startup.
As of October 2014, the apps that use this mechanism on Google Play are:
- DragonBox Algebra 12+
- DragonBox Elements
How this works for you depends on your device model, Google Play app and services version number, and your current internet connection.
As explained on Android's blog:
On most newer devices, when users download your app from Android Market, the expansion files will be downloaded automatically, and the refund period won’t start until the expansion files are downloaded. On older devices, your app will download the expansion files the first time it runs, via a downloader library which we’ve provided below.
Here are a few different scenarios:
Google Play downloads the APK and its extension(s) at onceIn this case, the package size displayed will be over 50M. (Similar to what is displayed in Step 4 above).
Google Play downloads the APK without the extensionIn this case, the app will propose you to download the APK once you start the app. You should make sure you have a stable internet connection. Once the package is downloaded, it will be extracted and the app will start normally.
