What is a 64-bit APK?

: Most modern Android devices use 64-bit processors. The Facebook APK for these devices is optimized to utilize the full range of 64-bit registers, leading to faster data processing and more efficient memory management. Performance Benefits

Modern smartphones use 64-bit processors to handle larger amounts of RAM and more complex computations efficiently. Using the 64-bit version (arm64-v8a)

The Android ecosystem has historically supported multiple instruction sets. However, to leverage the full capabilities of modern processors, Google mandated that apps distributed via the Google Play Store provide 64-bit versions. For a complex application like Facebook, this transition was critical for maintaining performance parity with modern hardware. 2. Technical Advantages of 64-bit Architecture
