According to news on April 2, the Xiaomi Open Platform shows that Xiaomi, OPPO, and Vivo three app stores jointly promote the domestic Android ecosystem to upgrade support for 64-bit architecture, as follows: end of December 2021: existing and newly released applications/games, It is necessary to upload an APK package containing a 64-bit package body (support dual packages on the shelf, and 64-bit compatible with 32-bit two forms, no longer receive APK packages that only support 32-bit);
- End of August 2022: The hardware supports 64-bit systems, and will only receive APK packages containing 64-bit versions;
- End of 2023: Hardware will only support 64-bit APKs, 32-bit apps will not work on the terminal.
The notice pointed out that developers need to take active measures to promote the 64-bit architecture upgrade, for overdue applications that have not been adapted, or take relevant measures to ensure user experience, including but not limited to “search label prompts”, “installation links are not adapted reminders”, “Sub-Type Shield”.
It is reported that the new Cortex-X2 super core and Cortex-A510 small core have completely abandoned support for 32-bit software, resulting in the current and only Cortex-A710 large core that is compatible with 32-bit software.
This means that on all flagship SoCs based on the ARM v9 instruction set (such as Snapdragon 8, Dimensity 9000, Exynos 2200), 32-bit software will be forced to “lock” to run on the big core.
Neither very large cores nor small cores can be used, resulting in lower energy efficiency. Specific to the user experience, the mobile phone will be abnormally hot and power consumption, so the promotion of 64-bit Android applications aims to improve the daily user experience of users.
