First of all we create our application view using xml layout. Our layout consists of the only one
full screen component of class org.opencv.android.JavaCameraView. This class is implemented inside
OpenCV library. It is inherited from CameraBridgeViewBase, that extends SurfaceView and uses
standard Android camera API. Alternatively you can use org.opencv.android.NativeCameraView class,
that implements the same interface, but uses VideoCapture class as camera access back-end.

After creating layout we need to implement Activity class. OpenCV initialization process has been

Building camera wrapper for Android 3.0.1:
1) Get sources of Android 2.3.x (2.3.3 were used)
2) Apply patches provided with this instruction to frameworks/base/include/camera/ICamera.h and frameworks/base/include/camera/Camera.h
3) Get frameworks/base/include/gui/ISurfaceTexture.h and frameworks/base/include/gui/SurfaceTexture.h from Android 4.0.x (4.0.3 were used) sources and add them to your source tree.
4) Apply provided patch to the frameworks/base/include/gui/SurfaceTexture.h.
5) Pull /system/lib from your device running Andoid 3.x.x
6) Edit <Android Root>/development/sdk/platform_source.properties file. Set Android version to 3.0.1.
7) Build wrapper as normal using this modified source tree.

*********************************************
Base Loader Callback Interface Implementation
*********************************************
.. highlight:: java
.. class:: BaseLoaderCallback
Basic implementation of ``LoaderCallbackInterface``. Logic of this implementation is
well-described by the following scheme:
.. image:: img/AndroidAppUsageModel.png
Using in Java Activity
----------------------
There is a very base code snippet implementing the async initialization with ``BaseLoaderCallback``.
See the "15-puzzle" OpenCV sample for details.
.. code-block:: java
:linenos:
public class MyActivity extends Activity implements HelperCallbackInterface
{
private BaseLoaderCallback mOpenCVCallBack = new BaseLoaderCallback(this) {
@Override
public void onManagerConnected(int status) {
switch (status) {
case LoaderCallbackInterface.SUCCESS:
{
Log.i(TAG, "OpenCV loaded successfully");
// Create and set View
mView = new puzzle15View(mAppContext);
setContentView(mView);
} break;
default:
{
super.onManagerConnected(status);
} break;
}
}
};
/** Call on every application resume **/
@Override
protected void onResume()
{
Log.i(TAG, "Called onResume");
super.onResume();
Log.i(TAG, "Trying to load OpenCV library");
if (!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this, mOpenCVCallBack))
{
Log.e(TAG, "Cannot connect to OpenCV Manager");
}
}
Using in Service
----------------
Default ``BaseLoaderCallback`` implementation treats application context as ``Activity`` and calls
``Activity.finish()`` method to exit in case of initialization failure.
To override this behavior you need to override ``finish()`` method of ``BaseLoaderCallback`` class
and implement your own finalization method.

.. _Android_OpenCV_Manager_Intro:
************
Introduction
************
.. highlight:: java
OpenCV Manager is an Android service targeted to manage OpenCV library binaries on end users devices.
It allows sharing the OpenCV dynamic libraries between applications on the same device. The Manager
provides the following benefits\:
#. Less memory usage. All apps use the same binaries from service and do not keep native libs inside themselves;
#. Hardware specific optimizations for all supported platforms;
#. Trusted OpenCV library source. All packages with OpenCV are published on Google Play market;
#. Regular updates and bug fixes;
Usage model for end user
------------------------
.. image:: img/AndroidAppUsageModel.png
First OpenCV app\:
#. Any OpenCV-dependent app is installed from Google Play marketplace or manually;
#. At the first launch, it suggests installation of OpenCV Manager;
#. Then OpenCV Manager is downloaded and installed, using the Google Play application.
#. When Manager has been started, the application suggests installation of OpenCV library for the
target device architecture if it is necessary;
#. After the installation is finished, the app may be launched.
Subsequent launches of OpenCV apps\:
#. Any OpenCV-dependent app is installed from Google Play market or manually;
#. At the first launch, the app starts as usually;
#. If the selected OpenCV version is not installed, OpenCV Manager suggests installing OpenCV
library for the target device through Google Play marketplace;
#. After the installation is finished, the app may be launched.
Architecture of OpenCV Manager

Java OpenCV Loader
******************
.. highlight:: java
.. Class:: OpenCVLoader
Helper class provides common initialization methods for OpenCV library.
boolean initDebug()
-------------------
.. method:: static boolean initDebug()
Loads and initializes OpenCV library from within current application package. Roughly it is
analog of ``system.loadLibrary("opencv_java")``.
:rtype: boolean;
:return: returns true if initialization of OpenCV was successful.
.. note:: This method is deprecated for production code. It is designed for experimental and local
development purposes only. If you want to publish your app use approach with async
initialization.
boolean initAsync()
-------------------
.. method:: static boolean initAsync(String Version, Context AppContext, LoaderCallbackInterface Callback)
Loads and initializes OpenCV library using OpenCV Manager.
:param Version: OpenCV Library version.
:param AppContext: application context for connecting to the service.
:param Callback: object, that implements ``LoaderCallbackInterface`` for handling connection
status (see ``BaseLoaderCallback``).
:rtype: boolean;
:return: returns true if initialization of OpenCV starts successfully.

Manager Workflow
****************
.. _manager_selection:
.. include:: ../readme.txt
First application start
-----------------------
There is no OpenCV Manager or OpenCV libraries:
.. image:: img/NoService.png
Additional library package installation
---------------------------------------
There is an OpenCV Manager service, but it does not contain appropriate OpenCV library.
If OpenCV library installation has been approved\:
.. image:: img/LibInstallAproved.png
If OpenCV library installation has been cancelled\:
.. image:: img/LibInstallCanceled.png
Regular application start
-------------------------
OpenCV Manager and OpenCV library has been already installed.
