There is a similar thread here, that says you can unzip the apk file and check the lib folder(if it exists), and all the architectures that are in the lib folder are supported by your apk. The thread I am refering to is this
The sdk we are using (apportable) outputs an apk with just the 'armeabi' folder in the lib folder. In 2019, all new applications and updates will have to have an apk that supports 64bit.
I am just wondering what does armeabi mean, is it just 32bit support or am I safe and it also supports 64bit?
There is some info about the different architectures in this post but I wanted to make sure that I am not missing something.
