Problem using OpenCV2.3.1 with Android Native Activity
I solved the problem there. It was my fault (as usual xD) the problem was I was writting in my Android.mk this line: LOCAL_STATIC_LIBRARIES := android_native_app_glue, instead of this line: LOCAL_STATIC_LIBRARIES += android_native_app_glue. I needed the "plus" symbol, in order to add the new library and not deleting the previously loaded. Thanks anyway!!
@Adi Shavit - thx
Change LOCAL_STATIC_LIBRARIES := android_native_app_glue to LOCAL_STATIC_LIBRARIES += android_native_app_glue. Note the plus sign. This will add the new library without deleting the previously loaded one. Source: Edanna in the comments
Maybe you should take a look at the V4L interface? You might want to check out this thread: http://comments.gmane.org/gmane.comp.handhelds.android.ndk/2824
If I recall you can read directly from a camera's dev file in OpenCV.-James
