Its fine talking about semantics, but when numbers are crunched it paints a different picture.
The two largest markets in terms of telecoms are India and China. The latter has an expanding middle class who want iOS devices, that is where Apple's growth is coming from. Conversely Android plurally has the biggest market share in India bordering on on 2/3 if these figures are correct:

I love how everyone saying Android is dead when those two bits of information paint a very different picture. Android is actually expanding on a worldwide basis, given the different price points its available at. iOS will always command a significant part of any market its sold in.....but thats the thing not everyone can afford an iOS device in China, India and the rest of the world.
I agree growth will flatten for both Android and iOS in the developed economies, broadly speaking they will remain the same until about 2018-2019 when new battery technology is FINALLY released to the market. All of this tit for tat means nothing, on a worldwide basis Android is the dominant OS similar to how Windows in on desktops. That won't change, not until Apple decides to make a budget device, which I am 99% sure will never happen.
OS development will slow down for a little while and concentrate on reducing bloat (lets be fair both "pure android" and iOS have enough of it). This usually happens following OS releases which implement new look graphics and art styles. Marshmellow is effectively a rollup release concentrating on under the hood changes which fix the memory and battery issues of its predecessor. iOS 9 is broadly the same, there aren't a significant amount of new features, its mainly the same as Androids latest offering.
Android and iOS will remain the dominant operating systems for some time to come, Android will expand and continue to do so given its ability to be attractively priced especially in developing economies.
iOS and latterly iPhone will struggle, there aren't a lot of people in Africa who would buy an iOS device, as the cost of that alone might be as much as 2 years wages in some parts of the continent. China is providing new revenue streams for Apple, it is expanding at a vast pace....what happens after? There aren't a great deal of other markets which could supply further growth. Apple will always remain very profitable I have no doubt about that, like other Tech companies their revenues will flatline in some respects. For the next 2 years I think will prove to be their most valuable in revenue and productivity. If as most expect Apple does release a roundface watch, then they could cannibalise the market there.
Android will always expand where as iOS won't, we are mixing profitability with shelf life. iOS devices are the most profitable in the industry and as alluded too Apple rake it in. Depending on who you believe on a plural basis Android is actually a loss making ecosystem, the only company to profit from it is Google, as they control the marketing and adverts.
Then again maybe Android will die next year?
