What Percentage of Android Devices Run on a 64-bit Architecture? How many Android devices are using the ARM64 or x86_64 architectures, and how many are using 64-bit versions of Android that can run 64-bit apps?

My assumption right now is that it's still worth supporting 32-bit versions of Android for mobile apps, but these days more and more devices are 64-bit and make use of several GB of RAM. As of this month, Google is now requiring that new Android apps have 64-bit versions, so I'm wondering for how long it will be worth supporting both architectures.

Additionally, how powerful are average high-end 32-bit devices? Even if the marketshare of 32-bit devices is high, it could be worth dropping support if most 32-bit devices won't run any intensive apps or games anyway.

This question is related to another question about x86 usage.
I have not yet been able to view recent statistics, but
according to this article published end of 2017:


  The ARMv8 instruction set architecture rolled out 64-bit hardware support in 2014, and now almost every new Android device can run 64-bit code (but only 40 percent of active devices)


From this ARM's blog post:


  Nearly 90 percent of today’s Android devices deploy a 64-bit capable version of the OS (version 5.0 and above).


Statistics on the percentage of OS used can be checked here and here.
