I want to create an Android application in which i want to detect human body from an image. I haven't started coding yet(its just an idea), so i am not able to show you any codes. I heard about OpenCV face detection for android.
I have tried to use OpenCV face detection, But since i am newbie in android, i am not able to do so.
My question is "Is there anything in OpenCV that can help me to detect whole human body rather than just face?", if YES then "is there any tutorials regarding this?"
thanks for HELP in advance.
Yes, it is possible to detect the human body in the form of images or videos using OpenCV, follow the steps below in order to start:
Step1
Create a new OpenCV project in Android Studio. In this tutorial, it explains how to create a new OpenCV project in Android Studio.
Step2
The following links explain Human detection using OpenCV:
HOG Person Detector Tutorial
People Detection in OpenCV

I´m looking for some useful API or libraries for handwriting recognition in Android. I want to integrate it in my app but I don´t find anything. I saw in other post that it´s possible using Tesseract(but this work better for OCR image text recognition).
Also I found this API https://dev.myscript.com/ , but it doesn't work fine. Anyone of the demos that they provide work correctly in the phone. It crash when I write a lot or just tab the screen. I tried to follow their tutorials to integrate it in a single app with a single Widget and it doesn't work.
Someone knows some way to integrate handwriting recognition? It´s just for a simple view where I want to write something in the screen throught Handwriting and put the text in a EditText.
there are quite a few options out there.

I must implement an applcation that draws a heart on a person seen via an Android device camera(augmented reality stuff).
So, I must detect the shape/contour of the upper part of human body(head, neck, shoulders) in order to know where the heart must be situated. This stuff must be made in real time.
I've searched about this stuff but I haven't find something useful. Does anybody know some tutorials or examples of something related to this? Thanks.
I would recommend using OpenCV if the memory isn't a problem ( your app would be like 50 MB). There are plenty of tutorials to learn how to use OpenCV. Try Cascade Classifier
In case of face detection, as far as i know, android has a library for this. Camera.Face

i am new to android. Now i am working on face recognition android application. Can you please suggest me the best sdk which is open source and doesn't have any legal issues if it is used as an open source. I request your suggestions & support. Thanks one and all.
For face recognition on android try to use OpenCV SDk.
OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. The library contains algorithms that can be used to detect and recognize faces, identify objects, classify human actions in videos, track camera movements, track moving objects, extract 3D models of objects, and etc.
Follow the given instructions in this link: http://opencv.org/platforms/android.html.

I'm looking to do basic eye tracking using an Android tablet, hopefully to track the users eyes to allow movement of a cursor around the screen. I've been doing some searching, I've read a little bit about OpenCV and FaceL and have seen an example in another SO question here showing it is possible to track eye movement on android.
I was wondering if anyone knows of any good tutorials or sample code that would be good to refer to or work from? I'm looking for anything that can help me figure how to get this working. Even in its most basic form.
I found your question via comment.
FaceL use OpenCV too, but with python wrappers.
For basic ideas I recommend this:
eye tracking
eye detect
but they are in native C API (OpenCV 1.X), OpenCV 2.3 java wrappers use C++ API (OpenCV 2.X) syntax, so Mat instead Iplimage etc.
You can see new syntax in:
template matching
On android you can choose two way to access OpenCV - JAVA API (70% functions) or C++ (with android NDK)
Im using java side and think, all functions you would need are accessible via java side.
Hope that helped you a little ;)
Try Opengazer. Actually it is used in PC (linux/Mac). But you can get an idea where to start.

My first Android app is going to involve a front facing camera, and facial expression recognition. I did a lot of research, yet I couldn't find any Android libraries that involve any facial expression recognition. I basically want to measure reactions.
I'm thinking it MUST have been done somewhere in some app, can anyone point my research in the right direction? If not in Android, perhaps somebody may know of a library that I can port over?
I'd suggest getting the Android OpenCV port working as a good first step.
Due to real-time requirements for image processing, most of the face detection/recognition code you're going to see is likely to be in C++. Many systems may use OpenCV as a base and/or you can cobble together a reasonable solution from OpenCV's many low-level functions.
The CVCamera sample in there is also good for showing how JNI/NDK interop works on Android which can be helpful for interfacing with other code.
what about face.com? it's web(service) based, but supposed to be pretty good!
