The document discusses static analysis of context memory leaks in Android applications. It outlines how the Android lifecycle works and how objects like activities have a lifecycle controlled by Android. Context memory leaks can occur through static fields, threads, and managers that hold context references. The analysis detects these leaks by simulating the lifecycle, building a control flow graph, and using abstract interpretation. It identifies fields that point to contexts or context containers and uses backward analysis to determine if the field will leak based on what initialized it. The approach was evaluated on 8 open source apps and compared to the Lint analyzer.
