Hello Microsoft,
Recently I wrote to Google to provide Hangout app for Windows Phone. In reply they said that they are willing to provide Google Apps if device manufacturer are ready to collaborate with them in development process. Following text is copy of two paragraphs
of their reply.
Unfortunately, when developing an app for a third party device we need the collaboration of the manufacturer.
Like in the case of Mac we worked side by side, also with Ubuntu and other Debian based Linux distributions.
Together we achieved the apps their users enjoy now, as well once the app is developed it needs to follow
the manufacturer's store approval like any other app developed for them. As you can see by visiting
https://support.google.com/plus/answer/1216376?hl=en.
In the case of Microsoft we are more than willing to develop the app, we would love to support that market
share which is vast increase potential customers to use their mobile devices.
With Microsoft we've achieved the use of hangouts through their Desktop environments so far. But, we need
you as their mobile customer to present the need of the use of Google Apps in their mobile phone's so they
can support the development of mobile apps on their devices. We want to serve you in whatever device you
choose to have, but this can only be accomplished through the device users to convince the device
manufacturer to collaborate to develop an app from us.
I would love to see Google apps on my windows phones. Could you please communicate with Google, to bring Hangout and other apps to Windows Phone.
