问题
I am able to detect faces using open cv but I don't know how to process face recognition.
I googled a lot but I didn't find any articles or blogs that can guide me.
Can someone help me to develop face recognition App in android?

You can always use JavaCV that is a kind of wrapper for the native OpenCV functions:
See: Face Recognition on Android
In order to get everything working you have to extract some .so files to your libs folder in the project:
Follow the instructions on this page
Go to File > New > Folder, select your project as parent folder, type "libs/armeabi" as Folder name, and click Finish.
Copy javacpp.jar and javacv.jar into the newly created "libs" folder.
Extract all the *.so files from javacv-android-arm.jar, opencv-2.4.6.1-android-arm.jar, and ffmpeg-2.0.1-android-arm.jar directly into the newly created "libs/armeabi" folder, without creating any of the subdirectories found in the JAR files.
Navigate to Project > Properties > Java Build Path > Libraries and click "Add JARs...".
select both javacpp.jar and javacv.jar from the newly created "libs" folder.
Source: https://code.google.com/p/javacv/
Include javacpp and javacv in your libs folder: https://code.google.com/p/javacv/
Find the required jars in javacpp after download and extract the required SO files (yes, you can open the jar with WinRAR)
Compile and build the code experimented in: Face Recognition on Android
And here you go! It worked for me, so I'm sure it will work for you!

In Library OpenCV.vers. for Android go to folder "samples". Sample Face-Detection for you=)
