opencv-android

Example for using opencv with android.

1. Create a module named "opencv" for your android project.

2. Download opencv-android from http://opencv.org/downloads.html

3. Copy files from {opencv-android-dir}/sdk/java to opencv module.

4. Copy files from {opencv-android-dir}/sdk/native/libs to app/src/main/jniLibs

5. Add project dependency to your main module.

        dependencies {
            compile fileTree(dir: 'libs', include: ['*.jar'])
            compile 'com.android.support:appcompat-v7:21.0.3'
    
            compile project(':opencv')
        }
   

6. Load opencv library before using opencv java api.

        public class MainActivity extends ActionBarActivity {
        
        
            private static final String LOG_TAG = MainActivity.class.getSimpleName();
        
            static {
                System.loadLibrary("opencv_java");
            }
        
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
        
                Mat mat = new Mat();
                Log.d(LOG_TAG, mat.toString());
            }
        
        
        }
