== Overview <sec:th-overview>
Our objective is to make available some dynamic information to any analysis tool able to analyse an Android #APK.
To do so, we elected to follow the path of a few contributions we presented in @sec:bg, such as DroidRA~@li_droidra_2016, and use instrumentation.
Contrary to DroidRA, which uses static analysis to compute the values of strings and, from that, the methods used by reflection, we chose to use dynamic analysis.
To do so, we elected to follow the same approach as a few contributions we presented in @sec:bg, such as DroidRA~@li_droidra_2016, and use instrumentation.
As a reminder, DroidRA is a tool that uses COAL to compute reflection data statically, then instruments the application to directly call the methods.
Contrary to DroidRA, we chose to use dynamic analysis.
This allows us to collect information that is simply not available statically (#eg a string sent from a remote command and control server).
The tradeoff being the lack of exhaustiveness: dynamic analysis is known to have code coverage issues.
