[osg-users] Android osgPlugins

Fri May 1 23:47:05 PDT 2015

Hi,

If you built OSG in static, then the osgsimple sample should load properly
the cessna model without worry about that message. OSG usually use the
dynamic loading of the plugins and always emits that message even in static
if the "dynamic" plugins is not found, anyway osgandroid preconfigures some
of the required plugins in  the JNIosgDB.cpp filename using the macro
USE_OSGPLUGIN.

If it's not working, maybe is something related to how you compiled OSG, or
maybe your device has multiple external storages and the sample didn't
found the model in the expected path.

My build configuration for osg was:

cmake .. -DANDROID_NDK=/Users/rgaitan/Projects/android/android-ndk-r10c/
-DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake
          -DOPENGL_PROFILE="GLES1" -DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF          -DANDROID_NATIVE_API_LEVEL=15
  -DANDROID_ABI=armeabi
-DCMAKE_INSTALL_PREFIX=/Users/rgaitan/Projects/OSG/osg-trunk-android-static-gles1-sdk/
I hope you make it work soon :)

Regards,
Rafa.
