android-jni
|
|
|
|
this is an example of an android library project that has some reusable
|
|
code that exposes part of OpenCV to android. In particular this provides a
|
|
native camera interface for loading live video frames from the android camera
|
|
into native opencv functions(as cv::Mat's)
|
|
|
|
pre-reqs:
|
|
* build the opencv/android libraries - up one directory
|
|
* you need swig in you path for android-jni
|
|
on ubuntu - sudo apt-get install swig
|
|
others: http://www.swig.org/
|
|
|
|
to build:
|
|
|
|
make
|
|
|
|
that should work... If it doesn't make sure to edit the generated local.env.mk
|
|
to reflect your machine's setup
|
|
|
|
see the sample for how to use this in your own projects
|
|
|
|
If you only support armeabi-v7a or armeabi your final apks will be much smaller.
|
|
|
|
To build the class files, either start a new Android project from existing sources
|
|
in eclipse
|
|
or from the commmand line:
|
|
sh project_create.sh
|
|
ant debug
|
|
|
|
This should be linked to in your android projects, if you would like to reuse the
|
|
code. See Calibration or CVCamera in the opencv/android/apps directory
|
|
|
|
With cdt installed in eclipse, you may also "convert to C++ project" once you have
|
|
opened this as an android project. Select makefile project->toolchain other to do this.
|
|
|
|
Eclipse tip of the day:
|
|
You may get build warnings when linking to the project, complainging about duplicate something
|
|
or other in you .svn directories. Right click project->settings->java build path->source->excude paths->add
|
|
.svn/ and **/.svn/ should do it ;)
