Prerequisites:

• Android SDK
• Working Android NDK toolchain

Follow these steps to setup your dev environment:

1. Checkout InformaCam git repo

2. Init and update git submodules

   git submodule update --init --recursive

3. Ensure NDK_BASE env variable is set to the location of your NDK, example:

   export NDK_BASE=/path/to/android-ndk

4. Build android-ffmpeg

   cd external/android-ffmpeg-java/external/android-ffmpeg/ ./configure_make_everything.sh

5. Build IOCipher

   make -C external/IOCipher/external/ ndk-build -C external/IOCipher/

Note: the 'make' build is setup to work with the Android NDK r8e. If you are using an older version, or you are using the 32-bit NDK on a 64-bit system, then you might need to set some variables manually as part of the command line. For example, using the 32-bit NDK on a 64-bit system:

make -C external/IOCipher/external NDK_PROCESSOR=x86

Or using an older compiler version:

make -C external/IOCipher/external NDK_COMPILER_VERSION=4.4.3

6. Build JNI for JpegRedaction

   ndk-build

7. Using Eclipse

   Import into Eclipse (using the "existing projects" option) the projects in this order:

    external/OnionKit/library
    external/android-ffmpeg-java/
    external/IOCipher/
    external/ODKFormParser/
   

   Using ANT

    ./setup-ant.sh
    ant clean debug
