androidarm64

androidarm64 refers to the 64-bit ARM architecture specifically as implemented within the Android operating system. ARM is a family of reduced instruction set computing (RISC) architectures commonly used in mobile devices and embedded systems. The "64" signifies that the architecture supports 64-bit memory addressing and processing, offering advantages over its 32-bit predecessor.

When an Android application is compiled for arm64, it means it is optimized to run on devices powered by 64-bit ARM processors. This allows for a larger amount of RAM to be utilized and can lead to improved performance and efficiency for certain tasks. The Android ecosystem has largely transitioned to supporting 64-bit architectures, with most modern Android devices featuring arm64-compatible chipsets. Developers typically target both 32-bit (armeabi-v7a) and 64-bit (arm64-v8a) architectures to ensure compatibility with a wider range of devices. However, the trend is increasingly towards 64-bit native support.
