Why Google Is Tightening Android App Memory Limits Starting 2027

As hardware costs climb and global memory resources stay tight, phone and terminal makers are scaling back mid‑range and low‑end device configurations, creating an increasingly visible "memory crisis" on the device side. To prevent poorly optimized apps from degrading multitasking experience and system stability, Google announced new enforcement rules for Android applications.

Phase 1, effective February 2027, introduces hard performance and memory metrics. Evaluation will use the P90 value from a 28‑day data collection period. Memory caps are tiered by physical RAM; for an 8 GB device, foreground apps may not exceed 2.25 GB of RAM, while background or user‑perceived services are limited to 1.5 GB. Devices with 16 GB or more are generally exempt, and games follow a slightly different rule set. Bitmap memory is also limited: 200 MB for foreground/background states and 400 MB in cached state. Additionally, Google requires DEX code optimization—apps must compress, obfuscate, and shrink Dalvik executable files, aiming for at least 25 % optimization coverage to curb memory use, speed up launch, and improve runtime performance.

Phase 2, taking effect in April 2027, focuses on enhancing Zero‑Tap Sign‑In and device‑migration experiences. Google recommends that Android developers fully integrate the Android Restore Credentials API, enabling seamless credential transfer across devices, reducing user friction, and mitigating security risks such as phishing and credential theft.

Apps and games that fail to meet these standards will not be removed from Google Play, but their recommendation exposure and publishing capabilities will be strictly limited starting February 2027. Developers can preview the relevant evaluation metrics in the Play Console before the end of 2026 and begin targeted optimizations.

This ecosystem‑wide memory defense marks a countdown to a new definition of "smoothness" for Android, driven by code compression and dynamic memory control in an era of rising hardware costs.
