I am looking in implementing Augmented Reality in mobile (android - eclipse/ ios - xcode).
The concept that I wanted to do is generate object randomly around the area.
This concept is very similar to "iButterfly" which is currently in appstore/playstore.
I am new in AR type of development.
But I have gone through some research about AR. I looked into Vuforia, Metaio and also Wikitude. All I able to get are the information of creating object based on Marker/Target, Point of Interest and Location based.
I would like to ask for some pointers/opinion/information on creating object without tracker/marker?
The latest version of Vuforia introduced Smart Terrain technology. In this case, the camera can build a virtual environment of the physical environment. You can then augment in the space, and even build on physical objects within the space. See Getting-Started-with-Smart-Terrain for more information.

I have been looking for an up-to-date answer to the question:
What is the recommended AR Framework to use for Android App development?
I want to start to learn AR so a framework with tutorials, community, etc... is preferable. So far the 2 that popped out are: Vuforia (Free version / License) and ARToolkit (Open-Source).
While looking I didn't find a lot of content for developing in Android Studio, why is that? There's plenty of Unity + Framework X content, but none for Android Studio.
Looking for people to shed some light on this and share his/her experience developping AR apps.
Thanks already
Before it was Metaio, but it was bought by apple. I used for many years and it was ok but it is not available anymore for Android.
Aside from what you mentioned there is also Wikitude SDK and DroidAR:

There might be more but so far I haven't heard. It is also worth tracking the future development of Vulkan Api.

I've been looking into AR recently because I decided I should use it for my Android app and I found about Unity and Vuforia, which is probably the simplest way to implement AR. I've never before used Unity so I'm a complete beginner to it.
I've followed this video: https://www.youtube.com/watch?v=YvSrZqP0elQ and it's working on my phone.
Vuforia uses marker, which I don't want. I would like for it to render AR image on the ground. More accurately said, I would need it rendered so that it is vertical to your body and horizontal to the floor.
Is there a way to do this in Unity with Vuforia? It would be great if I got any kind of help, for example link to useful resource or documentation, explanation or even example. Thank you for your help.
Vuforia does not provide markerless. They hqve smart terrain but seems to be oriente for games and has not been updated for years.
There are some SDK available like Wikitude, but they provide it as beta.

I think ARToolkit does something similar called Natural Feature tracking (NFT).

What you may look for is SLAM but beware that the technology is not yet mature.
There is Kudan but it also has limitations as it seems to rely on hardware. Gyro for rotation so some Android device won't do.

I have some experience in Python and know that Kivy is a good platform to create python android apps. Though as side hobby, I am learning c#/unity for indie game development, I know unity is good for developing android game, but let's say I want to build a weather app on android, does unity have the capability to allow developers to do so?
Yes, Unity has the capability to create non-game applications for Android (and iOS). However, I would highly discourage it. Using Unity for non-game development is like building a house out of sheet metal. While it can be done, it's not the right tool for the job and anyone who sees it can tell.

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 interested in developing an android app that makes use of an OpenCV android port at http://code.google.com/p/android-opencv/. Particularly, I want to use SURF features which comes embedded in the OpenCV framework but I'm not sure if then I will be able to sell this app.
Anyway, is there any non-free app making use of any of the OpenCV android ports?
SURF is a patented algorithm. You need permissions to use it in commercial applications. SURF comes with OpenCV because there its being used for "academic" or "research" purposes, without any commercialization involved.
Read the license files of the particular port you are using.
The two different ports I googled and looked at in the past two minutes seem quite clear.
