As a first step of a *tesseract* *androïd* use, I try/achieve the build of 
*tesseract* and execute with a shell on my device. That's not a stock way 
to execute app on Androïd, but very instructive.
According NDK guides 
<https://developer.android.com/ndk/guides/standalone_toolchain>, § *C++ STL 
support*, the recommendation is to build static. So do I.

Back to NDK user group to get forward.
