问题
I'm developping an Android app in Xamarin Forms. This development in for a specific tablet, a Galaxy Tab active 2. I'm facing constraints and want that app to be 64 bits only. In the Android options on my project, I have only arm64-v8a selected in supported architectures. During deployment of the app, I'm unable to do it because the arm64-v8a is not supported.
Android ABI mismatch. You are deploying an app supporting 'arm64-v8a' ABIs to an incompatible device of ABI 'armeabi-v7a;armeabi'. You should either create an emulator matching one of your app's ABIs or add 'armeabi-v7a' to the list of ABIs your app builds for.
But the tablet has 64-bit compatible processors and the kernel is also 64-bit (uname -m : armv8l).
If I look at CPU capabilities, I have the following specs for ABI :
[ro.product.cpu.abi]: [armeabi-v7a]
[ro.product.cpu.abi2]: [armeabi]
[ro.product.cpu.abilist]: [armeabi-v7a,armeabi]
[ro.product.cpu.abilist32]: [armeabi-v7a,armeabi]
[ro.product.cpu.abilist64]: []
It confirms that arm64-v8a is missing.
My question is : is there any way to add or install arm64-v8a ABI into an existing Android ?
Thanks for any help
