Deep Performance Tuning

This document is an operational playbook for Android performance diagnosis and tuning. It contains example instrumentation tests, Gradle/adb commands, and guidance for memory and startup optimization. There are no indicators of malicious code, remote exfiltration endpoints, download-and-execute chains, or credential harvesting. The primary security considerations are operational: heap dumps and benchmark artifacts can contain sensitive data and must be collected and stored carefully (avoid running these against production devices without approvals, sanitize or restrict access to artifacts). Enabling LeakCanary in debug builds is appropriate; ensure such tooling is not accidentally included in production releases. Overall risk is low to moderate purely due to the nature of the debugging artifacts, not because of malicious content.
