[osg-users] Latest OSG cannot realize viewer under Android

[Jordi Torres]

Hi Michael,

I'm sorry I don't have the time now to dig into the problems you have. But
I strongly recommend you base your work in
http://www.openscenegraph.org/index.php/documentation/platform-specifics/android/178-building-openscenegraph-for-android-3-4,
I've tested it a number of times with success. Then you can make use of
osgAndroid if you target GL_ES 1 ( https://github.com/miragetech/osgAndroid ).
If GL_ES 2 is a must you are on your own, but I tested it with success some
time ago.

Cheers.
