So I'm currently working on an android app for a class project which essentially matches users who use the app to other users in vicinity that have similar interest inside the app as well. So the basic idea is, PersonA open up my app and there is a dropdown box that they can select say 1/10 interests options in the list. Then PersonB, who has already opened the app as well and specified their specific interest from the dropdown before can click a button that says "find a person near me within 100feet with my interest that I just selected". If the PersonA is within 100feet of PersonB with them both matching the interest selected, then PersonA is returned to the screen with where they are. How would you go about doing this solution in Android? Is there a library/class or some api that does this? I'm fairly new to android, so I'm not exactly sure how to approach this.
I've been looking through many forums and even stackoverflow questions, but can't seem to find exactly the way to implement this or even start to go about creating this solution. Any help is appreciated! Thanks :)

Based on this link it seems that Android N is coming up with a new feature that will let users build a medical profile which can be used by medical professionals in case of an emergency.
So, I've been searching around a lot but I cannot find any references to whether developers will be able to pull this information from the device. I guess it would be part of Google's People API, but right now I cannot find any references to this.
So, does anyone have any ideas whether this is possible or not? And if possible is there any documentation pointing towards it?
Hey !
I have an Android app where the user can search on a specific subject, let's take the word "Cats" for example. When the user submits the search I want to find an image similar or on the subjects the searched for. A search engine for images more or less. I want something "easy" to deal with, so I thought about integrating the Google Search API into my app. Let the user search Google, and take the first image that comes up.
However, I haven't found any example and I just need a push in the right direction. If you could give me an example API for my needs, that'd be great.
Apparently the Google Search API never was fully deprecated it's still up and running. It provides JSON data and is easily parsed with Android.
If anyone else needs an image API here's a test search: https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=searchquery&rsz=8&start=1&imgsz=small|medium
And the JSON reference: https://developers.google.com/image-search/v1/jsondevguide
I am new in android. My app is basically is to scan the QR code to obtain product information such as the image, name, description and price and choose to add to cart and continue to do so(scan the qrcode) till user choose to end shopping and click to proceed to cart and will be shown the total prices of the items selected. User then can click either to edit the cart or proceed to the checkout. I have been searching tutorial but cannot find a complete one. Can anyone guide me through proper code how could i do this?
I do not think you will ever find a complete tutorial for the your task. However, a quick googling led me to zxing which can be used for processing barcode. I didnt go through the examples provided there, but I believe they are easy to understand.
Edit:
This is an exact duplicate of another question in SO. see
Now if that answer seems not enough for you, I think you are new to Android. Just google Android and you will find plenty of tutorials available. Start with Layouts, Activities, Intents, Bundles, Event Handling. To build what you want you would need a blend of many such small small things. Good luck
You will most probably wont find one single complete A to Z tutorial satisfying ALL of your app requirements .
But you can search for code/tutorial implementing parts of your app , like reading QR code , proceeding to next item etc . You will have to figure yourself out how it all comes together.

I recently co-authored and published a simple app to test the Android waters and get used to deving for android:
https://market.android.com/details?id=com.parp&feature=search_result
The name of the app is ‘Parp’ yet if you search ‘Parp’ it doesn’t appear until after the fourth page of results (seems to fluctuate a bit). The results above it seem to have nothing to do with the word ‘parp’ and are only there because of the spelling similarity to words in their name/description. E.g. there are a lot of apps related to finding where you parked your car. I understand the link here, but I don’t see why an exact match should be so far down in the rankings. We have tried in incorporate the words ‘parp’ and ‘park’ into the description (without making it ridiculous) to move it nearer the top (it used to be past the 10th page of results) but we have only succeeded in getting it as far as page 4. Whilst I'm not expecting it to top out the results for any related search I was hopeing to get it onto the first or second page for its own name.
Does anybody have any pointers on what more we can do, how the marketplace ranks results, or how to choose good app names that should avoid clashes like this? Getting somewhere on the first page would be great, and I don’t see why it should be unachievable given that this is the only app on the market place that has ‘Parp’ in its title (that I'm aware of)!
You are not the only one who experiences this problems: http://androinica.com/2011/07/android-market-search-problems/
It seems that the android market search was updated and now ranks keywords or similar words higher then the exact title of the app. This is very bad for developers who get their users through word of mouth marketing and hope to get downloads through users remembering a unique app name like yours. At the moment there seems to be no solution to this problem.
I'm looking to make a new type app that when the user open it for the first time it will open up a pop-up menu that contains multiple check boxes that the user can select from and will then save their selections for later use. After the user selects their choices I would like to have a monthly based calender on this same screen that the user can select a date from and based on their selection this will then take them to a separate screen showing the news for that day.
I am fairly new to android app development and this will be my first go at it. I have read several books and websites but cannot seem to find the help I need to produce the code for the above desired functions. Any and all help with this will be much appreciated.
Read these tutorials and you'll be able to create just what you need
Tutorials
Your question is very vague in fact, so I will only suggest a few points to start reading from, that I believe are important.
I think that you will answer any other questions you may have by reading through the developer documents for Android and studying the supplied examples. But don't hesitate to ask another, more specific question if you run into trouble.
tl;dr
Activities (must read!)
Dialogs (you will need these)
Data Storage (also important for the app you describe)
If you're still lost, just get some sample code from the repository and toy with it.
Good luck!
