Hey guys i am looking for an application that can navigate inside a mall.We can adopt the idea of inputting our current location through a QR code or by taking a snap of any near landmark(like shop,name boards..),Then we can input where we want go?But the actual problem is How to build a map of the indoor?Can u suggest any such tool to create a map for android phones.Because after creating the map by programming the gyroscope sensor in android for proper routing,because application now knows the source and destination,so i think it can display the shortest route(like GPS),then we can start walking through that path with our phone.Whenever we violates route using gyroscope we can track it.I think it is possible,if we turn left instead of taking right then app will direct us it is a wrong way.But i need help to create the map.Can anyone please suggest any idea?

please----
I might be wrong, but I think that going off of GPS would be inaccurate. If I remember right, GPS is only accurate up to 10 meters or something like that.
Like I said, I might be horribly wrong, I'm just going off of what I remember

I am working with android studio for last few days, and I am pretty new here with this work. I am trying to implement a location sensor app. The basic idea is if my phone enters into some restricted area (would be predefined in app), some voice message will be popped up, Surely I have to keep the app running on background to test this. I headed with FusedLocationProviderClient and implemented a very basic getmylocation app for now, where my actual obstacle I found. The co-ordinates keep fluctuating all the time for a same place after the decimal points by some values[(xx.xfffff,yy.yfffff) where f are the fluctuating figures,and the app is supposed to work on the truth of that figures], so the sensor can never implemented if the measurement is wrong.
Anyone having idea, how to fix this or may be there are better alternatives to implement this thing? I am pretty new to this work, so I would request you to give explanation or some attachment/article links in support of your answer so that I can get things clear and straight forward.
If any details is required from my work, Please mention , so that I can update this question on next round edit.
Thanks in advance.
I am really new for android development and first of all I want to be sure if the approach explained below is possible or not. I have a longitude and attitude data coming from GPS and I want to display an arrow symbol on a Google Map android application. Is it possible? In addition to this, I want to draw line for indicating the road the vehicle passed that I track by GPS. Is there such a kind of implementation samples? I have a look at many videos and Web sites but have not found such a sample exactly performing these requirements. Could you please clarify me regarding to this issue?
Yes possible...see these links..

Happy coding!!
I'm wondering on one thing. There is a lot of apps for android that allow you to look on the stars and see labels near them or see airplanes with labels and data from public databases. The thing that I want to know is:
How application knows that it is looking on the specific part of the sky or area. Cause I also saw application that can point a building. I understand that there is a database with lat and lng (geo data) but I have no idea how to check from code that I'm looking on the specific part.
I don't want the code, I just need a clue to figure it out
Thanks in advance
Not exactly sure but i could give you a pointer . This subject comes under augmented reality . Google Goggles for example is one kind of app you are talking about , this application can tell you all about whats in a picture by using some special algorithms . But , you say you want to know of camera positioning etc.
I've done some research and arrived at a few other stack results:

Happy to help !
EDIT:
here's one more extremely helpful link (library):

I'm trying to create an app that will tell a person what zone of a building they are in. I'm using bluetooth dongles to get an approximate location, as oppose to exact location, and show the user on a map whereabouts they are. I would like it just to highlight the zone they are in, instead of a specific location.
I can get my hands on a floor plan of the building I am using so I'm just wondering if there is an easy way to incorporate this into some kind of map with an existing API? I found a question here which states that they just use an overlay on the image to show a marker of where the person is. Would this be a bit easier?
This is for my final year project so I would like to have some sort of flashy map if possible but I'm not sure where to start looking or if it's possible.
I also found this question which gives a great variety of apps that implement and indoor map, but I don't think I can just take this small piece of functionality that I need out of them as they seem to be complete apps.
Any information would be a great help. Anyone with experience in this sort of thing please share your knowledge :)
It doesn't sound like it'd be too complicated to just write your own custom view for this. Draw the map image to the canvas. Then for the zone the user is in, draw another 'highlight' graphic on top of the map that you just drew.
If you're not sure how to do this, there's a rather basic guide on how to create your own drawable widgets which should point you in the right direction. There are plenty of examples on drawing images to the canvas, eg this one.
I was wondering if anyone could explain or clear me out -- I am currently doing some project to identify trees using android. I suppose the main components I must use at this project is GPS, Camera API and Compass (Please let me know if anyone can think anything) -- I am still in a middle of researching about the project and the possible problems that might arise during implement the project for example if there are two trees are in the same line of sight or same line (overlapping), what information is going to be displayed? How I can tell my software that I am actually want to display the front tree not the back of the tree? What sort of information or API will determine this? I mean does the camera or compass or GPS or even the database of the location of tree will determine it?
Can anyone please give me some idea, how I can tackle this kind of problem? Or perhaps if anyone know any tutorials that I can learn etc?
Much appreciated.

There is no existing api that would let you determine this specifically. I can image that you could estimate object identifications based on gps location. If you had waypoints in front, you could use the compass to get a direction and then approximate the gps region in front of you. Then try to see if you know of any prior waypoints that are in that area. Obviously, the one you see in direct line sight is the closest, and this would probably be the heuristic.
The camera will have almost no use in this case other than a view finder. If you are looking to segment images in order to differentiate between different objects, consider this impossible with google api, or any mobile application. This is difficult enough to do for professional researchers who can isolate variables..
The gps approximations are pretty trivial, however I am not confident as to how accurate or often a compass returns direction.
