Looks to me you should put points on that feature request, now solid number two in the top ten :
11151 - Add support for building apps for Google’s Android mobile smartphone OS
<https://xojo.com/issue/11151>
Since Number one is 64 bit support that is already in the pipe line and will be a reality when 2015R3 is released, it is time to move the point to it to push Android support to the top.
Android is the leader of all computing devices OSes (mobile, desktop, laptop) according to statistics, such as Android's Share of the Computing Market
My experience with the Play Store is very limited, as I posted only one little test app when I played with B4A last year. But it seems to me that market is promising, somewhat with more potential than the App Store for consumer software. At least my app can be found in the play store, while the one I have in the App store does not come up, even when I enter its exact name ! The App Store is a mess unless you got millions in advertising.
That said, Android is not a walk on rose petals. Fragmentation is no joke, with screen resolution to start with. In B4A, autoscale eases somewhat the process, making the layout show proportionally no matter which screen size, a bit like RubberViews. Problem is, fonts and pictures may still need management.
When it becomes outright terrible is rotation. Contrary to iOS where Auto Layout takes care of rearranging controls, even autoscale does not follow, as the aspect ratio has changed (autoscale works only for a given aspect ratio, Portrait or landscape). As far as I could figure, there are no third party auto layout solutions for B4A. So in practice, an app must have a set of views for Portrait, and another one for Landscape.
I strongly believe Xojo should investigate Android, though. Even if, at this time, 64 bit is the topic of the day with a coming release that demands a lot of work, and if iOS needs a whole lot of love to approach the maturity of Desktop, with a more complete set of controls to start with.
