+Package Content
+***************
+
+The package provides new OpenCV SDK that uses OpenCV Manager for library initialization. OpenCV Manager provides the following benefits:
+
+* Less memory usage. All apps use the same binaries from service and do not keep native libs inside them self;
+* Hardware specific optimizations for all supported platforms;
+* Trusted OpenCV library source. All packages with OpenCV are published on Google Play service;
+* Regular updates and bug fixes;
+ 
+Package consists from Library Project for Java development with Eclipse, C++ headers and libraries for native application development, javadoc samples and prebuilt binaries for ARM and X86 platforms.
+To try new SDK on serial device with Google Play just install sample package and follow application messages (Google Play service access will be needed).
+TO start example on device without Google Play you need to install OpenCV manager package and OpenCV binary pack for your platform from apk folder before.
+See docs/doc/tutorials/introduction/android_binary_package/android_binary_package.html and docs/android/refmain.html for details about service.
+On-line documentation will be available at address: http://docs.opencv.org/trunk

+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 of different versions 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 them self;
+#. Hardware specific optimizations for all supported platforms;
+#. Trusted OpenCV library source. All packages with OpenCV are published on Google Play service;
+#. Regular updates and bug fixes;
+
+Usage model for target user
+---------------------------
+
+.. image:: img/AndroidAppUsageModel.dia.png
+
+First OpenCV app\:
+
+#. User downloads app dependent from OpenCV from Google Play or installs it manually;
+#. User starts application. Application asks user to install OpenCV Manager;
+#. User installs OpenCV Manager from Google Play Service;
+#. User starts application. Application proposes to user to install OpenCV library for target device and runs Google Play;
+#. User runs app in the third time  and gets what he or she wants.
+
+Next OpenCV app\:
+
+#. User downloads app dependent from OpenCV from Google Play or installs it manually;
+#. User starts application.
+#. If selected version is not installed Manager asks user to install OpenCV library package and runs Google Play;
+#. User runs app in the second time and gets what he or she wants.
