How to integrate opencv manager in an android app

Question

I\'m developing an android app that uses opencv libraries which is opencv manager app. It requires opencv manager to be installed previously, I want to integrate the opencv

Answer 1

1 - Add the OpenCV library project to your workspace ( Use menu File -> Import -> Existing project in your workspace.)

2 - In application project add a reference to the OpenCV Java SDK in Project -> Properties -> Android -> Library -> Add select OpenCV Library - 2.4.8.

3 - Add a folder and name it "jni"

4 - Add an Android.mk file into jni folder. Its body should look like below:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

# OpenCV
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=STATIC
include ../../sdk/native/jni/OpenCV.mk

5 - Add an Application.mk file into jni folder. Its body should look like below:

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-9

6 - Add this to your Activity

static {
        if (!OpenCVLoader.initDebug()) {
            // Handle initialization error
        }
    }

7 - In case you have added following code to your Activity, comment out OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_8, this, mLoaderCallback); You don't need to load OpenCV on resume event any more.

@Override
    public void onResume() {
        super.onResume();
        //OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_8, this, mLoaderCallback);
    }

    private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
        @Override
        public void onManagerConnected(int status) {
            switch (status) {
            case LoaderCallbackInterface.SUCCESS:
                //OpenCV loaded successfully
                break;
            default:
                super.onManagerConnected(status);
                break;
            }
        }
    };

Have a look at this too: http://docs.opencv.org/trunk/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html#application-development-with-static-initialization

Got another solution by installing open Cv from my app by using this lib AutoInstaller
