Is it possible to know with which version of AIR was aab/apk built?

[GeneralVimes]

That's the question :) I noticed that in the past, about 10 months ago, there was a time when ANRs from my game was quite low, but after one of the updates it began to grow. I'd like to rebuild a game with an older version of AIR and resubmit it, but I don't remember which AIR version I used then. Is it possible to know this somehow, by opening aab or apk?

There may be a few ways of doing this... the one I just tried was to pull out the "libCore.so" from the APK file (under a lib folder) and then grep it:

$ grep -ao '[0-9][0-9]\.[0-9]\.[0-9]\.[0-9]' libCore.so

which should display the version string (as well as most of the 'localhost' IP address a few times!)

There's a class definition in the dex stuff but I'm not sure how easy that would be to get at... but in case it helps:

air.com.adobe.appentry.GetVersionCode.AIR_BUILD_VERSION

And then if you were able to change the SWF file in your application (unzip the apk, change it, re-zip and re-sign), you could try checking the AS3 Capabilities version value...

But also ... I think just run it up with ADB connected. Fairly sure AIR always prints out the version and CPU architecture as it starts up....

10-30 08:47:43.706 12323 12323 I AIR VERSION: :50.2.3.6
10-30 08:47:43.706 12323 12323 I DEVICE ARCH: :arm64-v8a

Thank you so much!

Also you can see it in Scout.

Is there a way to get AIR ARCH dynamically?
I need to know if app is built for armv7 or armv8...

thanks

You can use flash.system.Capabilities - the cpuArchitecture for the family and cpuAddressSize for the 32 vs 64 bit.
