"Google has already announced its intention to make the Google Play Store 64-bit only later this year"
The way this was wrote suggest that the Google Play store will stop supporting 32-bit devices, which worried me as I have 2 perfectly functioning devices running 32bit versions of Android. So I did some further research and found the official line from Google is this:-
"We are not making changes to our policy on 32-bit support. Play will continue to deliver apps to 32-bit devices. This requirement means that apps with 32-bit native code will need to have an additional 64-bit version as well."
