Found! h2pas (not ht2pas) in fpc/bin !
Yes! Please, send me your linux "h2pas" [32 bits] or
put it in LAMW github [folder "ide_tools"].
NOTE 1: About "Import C Stuff".
Open a LAMW project, go to LAMW "Import C Stuff". LAMW will
produce a library [*.so] and put it in the same folder of "controls.so".
Then "h2pas" will produce a header conversion (*.pp) for each ".h" and put it in folder "..../jni". Add the "*.pp" stuff to "uses" section and.... have fun!
NOTE 2. There is some issue/bug with Android < 4.1 (already explained here in the forum by @yury_sidorov). So stay with 4.1+.
