### AI overview

This tutorial describes GCStress, a Java application that deliberately creates garbage-collection pressure through repeated random byte-array allocations and cache removals. It explains how to integrate it into Google's Now in Android app, trigger it with an Android broadcast and adb, and observe effects such as skipped UI frames, possible ANRs, and potential out-of-memory errors.
