How to select an ARM-based AVD in Genymotion?
Start the device from an arm64 recipe or image, not an x86_64 one. For Genymotion SaaS, create or choose an official/custom recipe with arm64 and then launch the instance from that recipe: Deploy Applications and Get Started with Genymotion PaaS.
If you are installing an APK, make sure the app also matches the device architecture. On arm64 images, use arm64-v8a or arm apps, and on x86_64 images use x86/x86_64 apps.
