This document provides instructions for installing OpenCV on Android. It outlines decompressing OpenCV source code and the Android NDK, configuring the Makefile, building the source and android-jni, modifying build files, and building a sample CVCamera project to test the installation.

4. Why OpenCV?

5. Open Source?

6. Commercial Use?

7. High Performance?

8. Keep on Going?

9. Portability?

12. Decompress OpenCV source code: tar xvf ~/Downloads/OpenCV-2.2.0.tar.bz2

14. Mkdir the build directory: mkdir build

16. Decompress the Android NDK: tar xvf ~/Downloads/android-ndk-r4-crystax.tar.bz2

18. Config the Makefile: cmake -D NDK_ROOT=~/Working/OpenCV-2.2.0/android/android-ndk-r4-crystax ../

20. Start to build source code: make

23. Build the android-jni: (in OpenCV-2.2.0/android/build) cd ../android-jni make HOME=/home/neutron/Working/OpenCV-2.2.0/android

25. Run the ant java based build: sh project_create.sh ant compile

27. Modify the build.xml file in android-jni: vim build.xml

29. Build the sample project – CVCamera: (in OpenCV-2.2.0/android/android-jni) cd ../apps/CVCamera cp sample.local.env.mk local.env.mk Modify the HOME variable in local.env.mk sh build.sh sh project_create.sh ant debug ant install
