When unsure, choose a universal package. It is usually larger but includes components for multiple device types.
Know the common architectures
Most recent Android phones and tablets use arm64-v8a; older 32-bit devices use armeabi-v7a; x86 and x86_64 are most common in emulators and a few older devices.
Find the CPU in system information
Open About phone in Settings or use a trusted device-information tool and find CPU ABI, instruction set, or architecture.
Match the download label
Choose the file that exactly matches the preferred ABI. 64-bit ARM devices often support 32-bit apps, but not the other way around.
Choose Universal when uncertain
Universal packages contain resources for multiple architectures and offer the broadest compatibility. If parsing fails, check the minimum Android version and file integrity.
