In the previous chapters, we saw how to access the main native Android APIs from native code for efficiency purposes. In this chapter, we will bring the whole C/C++ ecosystem to Android, well, at least discovering the path, as decades of C/C++ development would be difficult to fit the limited memory of mobile devices anyway!
