In Linux it is quite common to build shared libs out of static ones by simple relinking, without explicitly exporting, relying on the implicit export of every symbol. This is exactly the opposite behaviour than in Windows where the default is to export nothing from the DLLs. If you enable visibility, the non-exported symbols will not be accessible anymore (and the linker likely removes them) and the application will likely crash when it loads such shared library. I think OSG is safe from this point of view due to its extensive macros dealing with imports/exports, but if you are using a library that doesn't have a DLL version on Windows (something Linux or Android-specific), you could get burned easily. > > to my Android.mk and that shrinks things a bit further too.

The armeabi and armeabi-v7a are the most common ones, in fact, if you want to cut down even more (and don't mind a bit of performance loss), armeabi binaries will run on everything. Regards, Jan
