Android starting supporting 64-bit architectures with Android 5.0. Currently, more than 40% of Android handsets online support 64-bit code, and are still compatible with 32-bit apps. But the day will come when Android won’t support 32-bit apps at all. Google is telling developers to be ready for three changes:
- New apps will need to be made using a recent version of Android for performance and security purposes. This will be required for new apps launching in August 2018 and later. For updates of current apps, this will be a requirement starting in November 2018.
- By August 2019, Google is asking developers to make sure that new apps and app updates with native libraries support both 64-bit and 32-bit versions.
- Early next year, Play will sprinkle a little security metadata on top of each APK to help verify the authenticity of each app.
