 We evaluated the reusability of the tools by measuring the number of successful analysis of applications taken in the Drebin dataset~@Arp2014 and in a custom dataset that contains more recent applications (#NBTOTALSTRING in total). 
 The observation of the success or failure of these analysis enables us to answer the following research questions:

+In this section, we describe our methodology to evaluate the reusability of Android static analysis tools.
+@fig:rasta-methodo-collection and @fig:rasta-overview summarize our approach. 
+We collected tools listed as open source by Li #etal, checked if that the tools where only using static analysis technique, and selected the most rescent version of the tool.
+Whe then packaged the tools inside containers and check our choices with the authors.
+We then run those tools on a large dataset that we sampled, and collected the exit status of the run (wether the tool completed the analysis or not).

+We first looked for the tools listed as open source by Li #etal.
+For the tools still available, we checked if they used dynamic analysis and removed them.
+We then checked if they where more rescent updates of the tools and select the most relevent version.
+Finally, we marked as non-reusable the tools that we could not setup within a period of 4 days, even with the help of the authors.
