Both the Pixel 7 and the Pixel 7 Pro are the first Android phones to exclusively support 64-bit software. This setup eliminates the need for the operating system to run 32-bit code, which uses less memory, and increases performance, and security. This setup for electronic gadgets is predicted to become standard over time.
As a result of everyone’s hard work and cooperation in the Android community, we now have a functioning ecosystem. Many changes were needed to the Android platform, tooling, Play, and your apps in order to make the switch to 64-bit-only devices. In 2014, we added 64-bit support, in 2017, we announced policy shifts, and in 2019, support will be mandatory for Google Play apps.
Your Device is efficient, Fats, Secure and utilizes less Memory
Due to the availability of additional registers and instructions, 64-bit applications are able to perform more quickly than their 32-bit counterparts. Furthermore, newer CPUs provide up to 25% better performance when running 64-bit code or eliminate support for 32-bit code altogether.
A more secure system is possible with 64 bits. The additional bytes in the address space improve the effectiveness of countermeasures like address space layout randomization, and the remaining bits can be used to ensure control flow integrity. Protecting your device with these measures may make it less likely that an intruder will be able to take control of it.
By eliminating the OS’s need for up to 150MB of RAM even when not running 32-bit apps, we can benefit from this change. These efficiencies in memory usage lead to less jank and fewer terminations of background applications.
Superior resources are now available to developers.
Improved tools, such as HWASan, are available to developers aiming for 64-bit, helping them catch memory errors and make their apps better.
OS Updates are now faster for vendors
The CTS testing time is cut in half when only 64-bit devices are used. With GKI, manufacturers can more quickly and easily release new firmware for their products.
Moving Forward
Now that 64-bit-only gadgets are available to consumers, programmers should give extra care to verifying that their apps and updates run smoothly on 64-bit-only hardware. Google Play now offers pre-launch reports that can be run only on 64-bit devices to check for compatibility issues before an app is released.
Keep in mind that while 64-bit-only devices will increase in popularity as more smartphones join Android Auto in this category, 32-bit-only devices will remain crucial for Android Go, Android TV, and Android Wear. Please keep up the support for 32-bit ABIs, as Google Play will still provide 32-bit apps for 32-bit-only devices.
