DroidRA is an instrumentation-based security analysis tool designed for Android applications that addresses the challenge of analyzing reflective calls in mobile apps. The tool employs a composite constant propagation approach to reduce the resolution complexity of reflective calls, which are commonly used in Android applications but difficult to analyze with traditional static analysis methods. By converting reflective call analysis into a constant propagation problem, DroidRA enables more accurate security assessments of Android applications compared to conventional Java call instrumentation techniques. The tool focuses on improving the precision of static analysis for Android apps that heavily utilize reflection, which is a common pattern in mobile application development but creates blind spots in traditional security analysis workflows.
