[osg-users] osgAndroid - Deploying and Debugging

[Rafa Gaitan]

Hi Shamim,

I added glustl_shared to be loaded dynamically before loading any
osgAndroid jni library, because linking it statically was giving a lot of
problems.

I don't recall having problems before, but I usually work on linux or mac
when I have to develop in android and OSG. Maybe is something related to
the r10e NDK?.

Anyway, could you check if you have in your
org.openscenegraph.android/libs/armeabi/ the library libgnustd_shared.so?,
if not, probably you need to copy it there from the NDK.

I don't recall if I copied it by myself that or it's automated somehow by
the NDK build system. But if you have it there along the libjni-osggles*.so
libraries it will be deployed within the apk.

Regards,
Rafa.
