+#summary OpenCV build instructions
+#labels Featured
+
+Using the NDK, OpenCV may be built for the android platform.
+
+The opencv port is in svn/trunk/opencv.  It is essentially a snapshot of the opencv trunk - rev 3096.  In the future this will be made compatible with trunk, but for 
+simplicity we are freezing opencv until this works consistantly.
+
+= pre-req =
+
+use crystax ndk 4 - http://crystax.net/android/ndk.php
+
+the crystax ndk supports the STL, expections, RTTI. opencv will not build with the standard android ndk!
+
+
+= The way =
+Using {{{r4}}} of the ndk, cd to the top level of opencv, and run 
+
+{{{ndk-build NDK_APPLICATION_MK=Application.mk}}}
+
+or build using the build.sh, which is just that line above...
+
+Assuming the ndk directory is in your path of course.
+
+this has advantages because it stores the library locally in the opencv folder. This is now the preferred method for building opencv.  The libraries will all be build as static libs which may be linked to from an external ndk project(see samples).
+
+== Using opencv in your applications ==
+See the samples directory.
+
+Two convenience makefiles have been created, one for the libraries and one for includes.  They expect OPENCV_ROOT and OPENCV_LIBS_DIR
+to be defined before including them.
+
+A sample Android.mk file for CVCamera follows, that requires opencv
+{{{
+LOCAL_PATH := $(call my-dir)
+
+include $(CLEAR_VARS)
+
+#pass in OPENCV_ROOT or define it here
+#OPENCV_ROOT := ~/android-opencv/opencv
+#OPENCV_LIBS_DIR := $(OPENCV_ROOT)/bin/ndk/local/armeabi
+
+#define OPENCV_INCLUDES
+include $(OPENCV_ROOT)/includes.mk
+#define OPENCV_LIBS
+include $(OPENCV_ROOT)/libs.mk
+
+LOCAL_LDLIBS += $(OPENCV_LIBS) -llog
+    
+LOCAL_C_INCLUDES +=  $(OPENCV_INCLUDES) 
+
+LOCAL_MODULE    := cvcamera
+
+LOCAL_SRC_FILES := android_cv_wrap.cpp image_pool.cpp yuv420sp2rgb.c Processor.cpp
+
+include $(BUILD_SHARED_LIBRARY)
+}}}
+
+
+= old way (not supported) =
+in {{{<ndk-dir>/apps}}} make a link to opencv
+{{{
+cd android-ndk-r4-crystax/apps
+ln -s ~/android-opencv/opencv/
+cd ..
+make APP=opencv -j4
+}}}
+this should make everything as a static lib.  These libs will be located in the android-ndk-r4-crystax/out/apps/opencv/armeabi
+folder.
+
+now in  you ndk project do the following:
+
+
+try building the samples/hello-jni project
+
+
+a sample Android.mk:
+{{{

+The LOCAL_LDLIBS are very picky.  {{{-L$(NDK_APP_OUT)/opencv/armeabi}}} is where the ndk builds opencv, usually in {{{<ndk>/out/apps/opencv/armeabi}}}. You can navigate there and see the static libraries that were built.

+ * These typemaps provide support for sharing data between JNI and JVM code

+ * allocate a direct buffer of the appropriate size.
+ *
+ * Example use:
+
+ * Wrapping:
+ * %include "buffers.i" 
+ * %apply int* BUFF {int* buffer}
+ * int read_foo_int(int* buffer);
+ *
+ * Java:
+ * IntBuffer buffer = IntBuffer.allocateDirect(nInts*4).order(ByteOrder.nativeOrder()).asIntBuffer();
+ * Example.read_foo_int(buffer);
+ *
+
+ * The following typemaps are defined:
+ * void* BUFF           <--> javax.nio.Buffer
+ * char* BUFF           <--> javax.nio.ByteBuffer
+ * char* CBUFF          <--> javax.nio.CharBuffer
+ * unsigned char* INBUFF/OUTBUFF  <--> javax.nio.ShortBuffer
+ * short* BUFF          <--> javax.nio.ShortBuffer 
+ * unsigned short* INBUFF/OUTBUFF <--> javax.nio.IntBuffer
+ * int* BUFF            <--> javax.nio.IntBuffer
+ * unsigned int* INBUFF/OUTBUFF   <--> javax.nio.LongBuffer
+ * long* BUFF           <--> javax.nio.IntBuffer
+ * unsigned long* INBUFF/OUTBUF  <--> javax.nio.LongBuffer
+ * long long* BUFF      <--> javax.nio.LongBuffer
+ * float* BUFF          <--> javax.nio.FloatBuffer
+ * double* BUFF         <--> javax.nio.DoubleBuffer
+ *
+ * Note the potential for data loss in the conversion from 
+ * the C type 'unsigned long' to the signed Java long type.
+ * Hopefully, I can implement a workaround with BigNumber in the future.
