Android 17 introduces memory limits for apps to combat RAM bottlenecks
Android 17 introduces mandatory memory limits for apps to prevent excessive RAM consumption and maintain system stability. The system assigns budgets, moving data to zRAM upon overload, and terminating processes if all buffers are exhausted. This feature rolls out first on Pixel devices, providing developers with optimization tools.
Android 17, the next major version of the mobile operating system, introduces an important new feature: the implementation of mandatory memory limits for individual applications. This step marks a paradigm shift in how Random Access Memory (RAM) is managed on smartphones.
The main goal of this measure is to prevent individual apps from consuming excessive amounts of RAM, which can demonstrably lead to a general decline in system performance. To manage this, the system will set a specific memory budget for every installed app, based on the device's total available RAM.
The procedure for overruns is regulated in several stages. If the allocated limit is exceeded, the data will first be moved to the compressed zRAM. If even this buffer is exhausted, the system will be forced to terminate the relevant process. These mechanisms are intended to ensure the overall stability and speed of the device.
The rollout of this feature will initially begin on Google Pixel devices and is expected to be adopted by other manufacturers later. Corresponding tools will be provided for developers to optimize their applications optimally for this new, more restrictive environment. For example, developers can test and adjust memory consumption using ADB commands.
