Google Play that started in 2011 has increased the number of countries from 30 to 130+ where it now support paid apps.
Further to provide a cohesive, pleasant experience for users, and to help Android developers capitalize on this growing international audience, Google has announced that developers can now include "localized images and a video URL to Google Play store listing for each of Google Play's 49 languages." "just as you've been able to add localized text," Google said.
Basically, what this means is that "developers can upload separate assets to ensure that users in, for example, the United States will see English-language graphics and video, while others around the world see materials in their own language."
Of course, it's still up to the developers to actually create the graphics and videos, as convenient as this new feature may be. A localized feature graphic can show translated text or add local flavor to your app -- for example, "changing its theme to reflect local holidays. Always make sure that your feature graphic works at different sizes."
Localized screenshots make it clear to the user that they'll be able to use your app in their language.
And, with localized videos, "devs can now include a language-appropriate voiceover and text, and of course show the app running in the user's language," google adds.
To add localized images and videos to your apps, you need to use the Google Play Developer Console preview, and review the graphics guidelines. Further, Google says, that it will be adding support for Multiple APK soon. And, those using APK Expansion Files can try the new Developer Console right now.
In the blog post Ellie Powers, Google Play Product Manager notes, "Once you've saved your application in the new Developer Console, automated translations become available to users on the web and devices -- with no work from you. And, also that after adding localized graphics, you won't be able to edit the app using the old version anymore."
