For those interested and if you missed it, Google Play will introduce some new rules next year, notably rules applying to the minimal version of targetSdkVersion according the permissions of your app (not detailed yet) in case you gonna submit a new app (august 2018) or update an existing app (november 2018)
Definitely something to follow next year. I guess they are willing to “stress” a bit their users, carrier and phone manufacturer to apply updates to their phones.
Well my understanding is that some features gonna only be available starting from a minimal android api level which could change regarding of their actual level (for example a feature who would be ok now on android 4 but would only be only available from level 6 from end of next year)
But I may be totally wrong and like I said, just something to follow. Right now it’s only a blog entry with one or two examples, still need more figures for me
