Bluesource has released a solution that switches apps using GMS (Google Mobile Services) for HMS (Huawei Mobile Services) to enable AppGallery distribution.

The open-source solution is called the Choice SDK and aims to save developers time and cost in converting their existing apps which use GMS and Firebase frameworks to be usable in Huawei’s ecosystem.

Martin Sprengseis-Kogler, Managing Partner at Bluesource, said:

“Businesses across Europe would like to join AppGallery but think it may take a lot of resources. In Choice SDK we created a simple standalone switch that removes the complexity out of the development process and enables brands to quickly and cost-effectively adapt and port their apps.

We’re delighted to have helped leading international enterprises with their app implementations for Huawei’s HMS ecosystem – particularly in the finance and banking sector – and we hope to continue to support more European businesses by making it easier to publish their apps.”

Choice SDK was originally developed for Bluesource’s client Raiffeisen Bank to help the Austrian bank make its app available for Huawei’s users. Bluesource since decided to make the solution open-source to help developers adapt their apps more quickly and safely.

Other businesses that have already used the Choice SDK to adapt their apps include TV broadcaster ORF, Austria’s Postal Service, Aktionsfinder, and Austrian railway firm ÖBB.

Georg Hanschitz, Head of Austria, Eco-device development at Huawei Consumer Group, commented:

“Open innovation is key and this is a great success story of collaboration and open-minded business. This solution will help developers around the world to adapt any GMS or Firebase related app for AppGallery.

I want to thank Bluesource for their dedication. We are proud that this solution is made in Austria and it is open-source now. This is free to use and easy to build in – for any kind of Android apps, worldwide.”

Huawei’s AppGallery has almost doubled its distributions over the past year—serving a total of 384.4 billion apps in 2020. The third-largest app marketplace now has 530 million monthly active users and has grown in Europe by 61.5 percent year-on-year to more than 42 million users. 

In September 2020, HMS 5.0 was unveiled with 56 ‘kits’ and 12,891 APIs. Apps integrated with HMS Core have more than doubled over the year to reach 120,000. Huawei now boasts 2.3 million registered developers – up 77 percent over last year – including 300,000 outside China.
