HarmonyOS developers face unique memory management challenges as the platform evolves. This guide synthesizes the core capabilities of DevEco Profiler and HiDumper, two essential tools for diagnosing memory issues in HarmonyOS applications. DevEco Profiler provides real-time heap analysis and allocation tracking, while HiDumper offers command-line access to system-level memory statistics. Together, they enable developers to trace memory leaks, identify excessive allocations, and optimize garbage collection behavior. The workflow typically starts with profiling in DevEco to spot anomalies, then uses HiDumper to drill into process-level details and confirm root causes. Practical tips include setting baseline metrics, comparing snapshots across sessions, and automating HiDumper scripts in CI pipelines. While the official documentation covers individual features, this integrated approach helps teams build a repeatable optimization process. For teams targeting HarmonyOS NEXT or migrating existing apps, mastering these tools reduces crash rates and improves user experience on resource-constrained devices.
