Probe Component for Fast Online OOM Diagnosis in Android Apps

The Probe component continuously monitors Android app memory, automatically captures trimmed HPROF snapshots when usage spikes, and analyzes them either on‑device with the HAHA library or on a server, enabling rapid OOM root‑cause localization, thread/FD tracking, and has lowered the rider app’s crash rate from 2‰ to roughly 0.02‰.
