The basic idea is simple: when you click on a link, if that link has an associated Instant App at the URL you get a tiny version of that app instead of the website. We played around with it a bit today at Google IO, and found that it was as fast (if not faster!) than loading up a web page with the same functionality. It works because developers can “modularize” their apps so they only serve you the parts that you need for whatever you clicked on — points on a map, a video, some home listings, a payment system, or whatever.
But take that idea and think on it a second: there’s a whole class of apps that you use once and never want to bother with again. Google’s example is a parking meter app. It works better as an app because it ties into Android Pay, but honestly you don’t want that thing cluttering up your app drawer most of the time.
This is why I tend to keep my Nexus 5X phone quite clean and clear of apps, I upload apps to my Nexus 7. If at all possible. Its discipline and I’ll be honest a bit of a pain, as my Nexus 7 relies on Wifi for network connectivity, but generally I think through the positives and negatives of installing each app and where it should go before hitting install.
Recently I installed the Easyjet app on my nexus 7, just so I didn’t have to print out my boarding pass (I have no printer and kinda hate printing). I used the app twice over a period of a week and that was it, uninstalled and gone. If I had instant apps, I would have been very happy with using it instead. Theres also other apps I just need for one task, like at a conference to vote (hey Thinking Digital & Herb), instant apps would so solve this problem; and if really that fast…!
Yes I hear the privacy concerns, but maybe it could be a standard android chooser/selector. Go to the play store and install the app, use instant app or force the service to give me a mobile alternative version.
Yes I hear, developers need to write their apps in a more structured way. But there can’t be much wrong with that? I remember back when I was still in Bristol, a talk about streaming apps, well its almost getting there; although I’m sure many will argue the webapp has already made this a reality.
