To clarify, the reducing APK size tip is mandatory, because Google Play won't allow x86 without x86-64.
If I make the change as you suggest, I get a warning from Google Play that some users won't be able to update, but I don't know if it is something to worry about.
My new APK says:
Native platforms | arm64-v8a, armeabi-v7a |
Supported Android devices: 8465 devices
The older APK.
Native platforms | 1 differentiating: x86 + 2 common: arm64-v8a, armeabi-v7a |
Supported Android devices: 8466 devices
I have no way of telling what that one(1) device I am excluding and if it is real.
Pardon me for not knowing, but are there no real tablets/phones with Intel x86 Processors, 32 nor 64 bit?
Some years ago, Intel gave me an award and had me in one of their promotional videos, all because I compiled an app for x86 (which too only a few seconds). Did Intel never make it into the market?
