Some applications use dynamic code loading and reflection calls that prevent static analysis tools from analysing the complete application.
Those behaviours can be analysed with dynamic analysis; however, the information collected is not enough to analyse the application: most tools do not have a way to process this additional data.
This can be detected with dynamic analysis; however, the collected data is not enough to analyse the application further: most tools do not have a way to process this additional data.
In this chapter, we propose to use dynamic analysis to collect information related to dynamic code loading and reflection, and to encode this information in the bytecode of the application to allow further analysis.
We compared the results of analysis on applications before and after the transformation, using tools like Flowdroid or Androguard, and found that the additional information is indeed processed by the tools.

We also compared the finishing rate of the tools, using the same experiment as in @sec:rasta, and found that the finishing rate is generally only slightly negatively impacted by the transformation.
