Pixel 7 and Pixel 7 Professional are the primary Android telephones to assist solely 64-bit apps. This configuration drops OS assist for 32-bit code, decreasing reminiscence utilization, bettering efficiency, and enhancing safety. Over time, we count on this system configuration to develop into commonplace.
Because of the efforts and collaboration of your complete Android group, our ecosystem is prepared. Transitioning Android units to 64-bit-only required many adjustments throughout the platform, tooling, Play, and, after all, your apps. We began by introducing 64-bit assist in 2014, asserting coverage adjustments in 2017 and requiring assist for Google Play apps beginning 2019.
Your system is quicker, safer and makes use of much less reminiscence
64-bit apps run quicker as a result of they’ve entry to additional registers and directions that are not out there to 32-bit apps. As well as, newer CPUs ship as much as 25% higher efficiency when operating 64-bit code and even drop assist for 32-bit code altogether.
64-bit may also help enhance safety. The larger deal with house makes defenses like ASLR more practical and the spare bits can be utilized to guard management stream integrity. These countermeasures might cut back the possibility an intruder can take management of your system.
Eradicating assist for 32-bit code saves as much as 150MB of RAM, which was utilized by the OS even when not operating 32-bit apps. These reminiscence financial savings lead to fewer out-of-memory situations that means much less jank and fewer background app kills.
Builders have entry to higher instruments
Builders focusing on 64-bit have entry to higher instruments comparable to HWASan for detecting reminiscence errors and bettering the standard of an app.
Quicker OS updates for distributors
64-bit-only system configurations halve the CTS testing time. Mixed with GKI, distributors can replace units quicker and extra simply.
Going ahead
With 64-bit-only units now reaching customers, we encourage builders to begin paying additional consideration to testing their apps and updates for 64-bit-only units. To assist this, Google Play now supplies pre-launch studies which can be run on 64-bit-only units to detect and report compatibility issues.
Word: Whereas 64-bit-only units will develop in recognition with telephones becoming a member of Android Auto on this group, 32-bit-only units will proceed to be vital for Android Go, Android TV, and Android Put on. Please proceed supporting 32-bit ABIs; Google Play will proceed serving 32-bit apps to 32-bit-only units.
