Making an app for accessing Office 365 ProPlus on Android smartphone

I am thinking of making an app to access the services of the Office 365 Pro Plus plan.
How should I mold the code of the app to help users install Office 365 ProPlus on their mobile android devices?
Also, Is there a way to help users select the Office 365 Pro Plus versions from the choices they get while subscribing to the service?

Thanks in advance.
