So I have a clocking in app we have developed on Powerapps that is ran on android tablets across multiple sites in the UK, what we want is to get the App to send the public IP address to our SQL database every time someone clocks in.
Would anyone have an idea on how to do this?
Thanks
I have tried looking for information online regarding this but can't find anything anywhere.

So basically I have made a few small apps in the past, but this is my first 'proper' app.
One of the main features of the app, and the bit that I am struggling with is that I need to be able to populate a ListView with all of the other users logged into the app, however I only want to display users that are within a set distance, for example 10 meters.
I tried using Bluetooth to achieve this, however that didn't work. I would now like to use location services to do this.
My idea is to have to app send the location of the device to an external server every few minutes and then all other devices can run a function that compare their location to others found on this server.
Does anybody know how I could go about achieving this, or know of any tutorials that cover a simpler topic. Thank you
Disclaimer: I'm not an android developer, but this seems like a design issue not a implementation issue so hopefully my comments below might be of some use...
I don't think there's an API that you can just set to "true" to get this functionality, so I think you're going to have to custom craft all the moving parts (and there are a couple). I would think the general process would be something like:
On the client:
User on client logs in to server with some sort of identity (i.e. "user#gmail.com")
Every X minutes the client app gets the current location (i.e. "100N 90E") and sends it up to a server
Every X minutes the client polls the server to see who is within 10 miles (i.e."joe#gmail.com", "mary#gmail.com")
On the server:
Needs some sort of authentication endpoints for getting a user's identity
Needs an endpoint for users to register their location ("user#gmail.com is at 100N 90E")
Needs a service to find out how far each user is from each other
Needs an endpoint to return the users within X miles (list generated from #3)
Each one of these steps shouldn't be difficult on their own and you can actually get pretty nuts with the distribution algorithm on server step #3 if you wanted to.
Some questions you can ask yourself are:
"How do I set up a server to listen for HTTP requests?" - Take a look into Node.JS for a simple solution
"How do I get a user's location in android?" - Easy google search finds plenty of documentation
"How do I write a service to continuously perform actions?" - Node.JS would again help with this
"Where will I store user's locations and their distances from each other?" - You can look into a NoSQL option like CouchBase or MongoDb. Or you could use MySQL for a more structured database.
Hope this helps...
Im working on an app that asks the user to input 5 words. I would like the app to notify the user if someone in the same vicinity has any words that match with the user. I was wondering whats the best way to go about this. Im not sure about bluetooth because I believe it requires the user to manualy make a connection with the other user. I was thinking of maybe uploading the users gps location and comparing it with other users. To be honest I have no idea how to go about this. Thanks for the help!!!
Have all devices communicate their location and "words" to a shared webservice. The webservice can then report back whether their are matches in the vicinity. Don't get distracted by fancy nfc/wifi/bt ideas if you don't need to :)
I want to let my app scan the users contactlist , and display the name of the contacts who also installed the app.
I have no idea where to begin with this . so if someone could help me getting started , that would be apreciated.
grtz
You will need to research ContentResolver because you will have to query the database containing the contacts. To do these queries, you will need the URI and column/header names for contacts db which can be found in the Contacts class.
You will also need users to register that they have your app on your own servers and the registration will need a piece of information about the user that other users would have in their contacts (the users phone number, email address, etc).
You will then need to query a few users at a time from the users contacts for this piece of information (using the ContentResolver and Contacts class), pass it to your server (as text) where it will check if they are registered, then send a message back to initial user (and possibly the match) that you found a match.
That's where you should start, and end :)
Note, you will need these permissions in the Manifest file:
android.permission.INTERNET
android.permission.READ_CONTACTS
First of all, welcome to StackOverflow. StackOverflow is for programming questions. As is such, a post asking for help should always provide a description of what you have already tried. If you haven't tried anything yet, I highly encourage you to try something, and post when you encounter a problem.
As your question stands now, we don't know what the problem is. Are you having problems scanning a contact list? Or are you having problems trying to figure out if another user has installed the app?
That being said, you will have to maintain a database for your app containing a list of people who have installed your app. When your app is launched on one device, do whatever you need to do to register the user in your database. Due to the nature of a "contact," one person's phone may only have their phone number, email address, or even just a name. This is of course something you will have to deal with in your implementation.
I have an application that uses the SQLiteDatabase as its database, because each application has its own, custom database (well, custom values), for another app I am making, I want to hose a single SQLiteDatabase that every app will access, for example one app adds a row, while another then reads it at a later time.
Is there anyway to do this? Everything I've found has left me believing there is not, but there has to be.
Any ideas?
Update:
I'm not sure if you've quite understood what I'm trying to do, sorry. The apps accessing this db are all the "same" app, but from different phones, for example, the database could be used to store a user id and their favorite color, so another phone could search their user id, and get the color in db with that user id –
I'm sorry if I did not make that clear enough
Of course there is way to do it! There is always a way!
Anywho, what I think you are looking for is a remote server. These can be done in a few way depending on how much money you have.
(1)If you're broke like me all the time, then you can make an extra computer you have at home act as a server for your app. This can cause a few ( :) hehe few) security issues for your home though. Also you will have a lot of traffic on your home network.
(2)Another option it's to get a domain name and web host. Most of the web hosting services I have seen offer database support. So what you could do is hop on, create your database on the web host server then link your app to your server. The cost on that varies based on your needs.
Really though, is your app interfacing with mulitple people? I can't think of a reason you would want this feature on any other phone (device) than your (relative to us customers) device. I rarely hand my device over to others, and never unless it's locked.
SQLite is serverless. In a situation as described there are no guarantees that it will work properly. Your solution is to create a database server that will cater to multiply Android clients simultaneously.
For more information on SQLite see LinuxForu.com and/or SQLite.org
First of all apologies if this is a duplicate but I'm browsing via my mobile and am having problems searching.
I'm new to android development and would like to know how to access the gmail contacts rather than phone contacts, I've followed a couple of tutorials and can list the contacts that are stored on the phone but I am unable to find a ContentProvider Uri for GMail!
I am presuming that they are accessed in the same way that phone contacts are but using a different Uri but so far have been unable to find any information on this!
Any help is greatly appreciated.
Thanks
