Im building an app that helps prevent patients from going missing or helps locate them ... im able to get co_ordinates and send them to the defined number via sms. because of time constraints im looking for help narrowing down what i should look into before attacking the next section. The question is there there a better way to go about sharing data between two apps on different devices rather than sms.
any tips on extracting information from messages would also be great ty.
I think push notifications may be the way forward for you, check out this write up from Google about how to implement them:

Introduction
I have a xy-problem
x: High level goal
I have dream: I want to store additional data to mails which are in IMAP. I the long run I want to be able to access this data via thunderbird and k9 (android app (mail use agent)).
Use cases:
I want to store a note in html format for this mail.
Upload a PDF file for this mail.
I want to store a re-submission date on the mail. Like google inbox snooze feature: Move the mail to a "do later" folder until the date is reached. (Evaluating this date and moving the mail to inbox again is not part of this question)
But I have no clue how to store additional data
y: My current thoughts about solving it
I need a way to identify a message in IMAP. I think the message id (without folder name) should work. I know that message IDs can have duplicates, but I see no other way. Please leave a comment, if you have a better idea.
Now I need a way to store this mapping somewhere:
`user#imapserver:message-id` --> `additional-data`
Question
How to store this mapping, so that thunderbird and k9 could access it?
Of course I know that thunderbird and k9 can't access this data today. How to patch them is a different question.
Background
I like free software and I like free communication. Up to now I use WhatsApp, Threema and other tools. But in the long run I want a free (like in software) solution. Email is wide spread, and I think it makes more sense to improve email than to create something new.
You could store annotations in a parallel mailbox as MIME messages using APPEND. You'd have to figure out a way to map annotations from one message to another.
So you can find the related message easily, you'll want it easy to search for. You could do something like using the message-id of the source message as the subject of the annotation message, or a transformation of the message id as the message id of the destination message.
Here are my thoughts on it... here is the current proposed and accepted standard for IMAP4 which is the current version...
https://www.rfc-editor.org/rfc/rfc3501
Here is a wiki link to show the previous versions and the progress that has been made over time ...
https://en.wikipedia.org/wiki/Internet_Message_Access_Protocol#IMAP4
I think the question is a good one, but maybe if your idea is good enough, contact the people that are in charge of the protocol and think about ways to potentially make IMAP5 with the kinds of functionality that you want to expand it to be able to utilize...
I would say that the best way would be to try making the IMAP protocol better. Read over all of the functionality that it currently supports and make suggestions to the group in charge of it. The additions that you are wanting to add sound great, but unless I misunderstood the question, I think that protocol updates might be the cleanest approach.
Sounds cool though.
Good luck... I hope you like my thoughts.
Have you considered Mailgun? It has an extensive API ( https://documentation.mailgun.com/api_reference.html#api-reference). Incoming messages can be stored, processed by your application and then sent via email. I believe you can add your own header field information (perhaps generating something like a GUID and using it for unique message tracking). Up to 10,000 emails/month are free (one of your preferences). If your application workflow and the API align, this might help get the job done.
I have a scenario where I register users to the system and after they are logged in then I would like to create something like a field called messages(i.e. Facebook messaging system) so 2 users can communicate between each other. This is just an idea but I am trying to find some resources and documentation on line without any luck of how can I achieve this. Can someone give me some advice please on what tools I could use in order to make this idea work ?
I am not asking for source code or so, I just need some advice on how I could achieve this or any kind of references to similar projects would be much appreciated.
Thanks in advance.
This is a perfect use case for a cloud pub/sub messaging service like Pusher or Realtime.co
Check this chat examples on github for Android and iOS:
https://github.com/realtime-framework/MessagingAndroidChat
https://github.com/realtime-framework/MessagingSwiftChat
Note: I work for SightCall. :-)
We offer a platform for realtime communication on mobiles and browsers. While we are best known for WebRTC Video, we also have a realtime data facility that makes it easy to send text-messages between two logged-in endpoints.
We have a sample Android App that shows how to use the framework. You can get an API key for free for a trial.

Of particular interest to you regarding sending/receiving text messages - notice the lines concerning the use of
rtcc.dataChannel().send(bytes, 0, uid);
This is where a text message is sent to a User named by their 'uid', and the method
#RtccEventListener
public void onDataChannelOutOfBandEvent(DataChannelOutOfBandEvent event)
This is where a text message is received as an event.
i want to make app that make a notification when breaking news has arrived to news website
during my search i found two ways to do that
1- using c2dm server & php & database
2- using timer that scan the website automaticly every time period i decide it
can any one help me by give me an example code for each method or a Tutorial for each method
I'm working on GCM as well. The first comment already told you the right way to solve your problem, but I wanna add something more is that This excellent tutorial
Read it, try to understand it. I think it is quite clear. Hope this help :)
C2DM is deprecated. You could use GCM instead. Go through this tutorial how to get started with it.
You can refer this too.
In my app i need something like that.In my app a user can easily be a member by signing up.Now when a user become a member then he can communicate with other members.Suppose a want to send a message(same message) to all users, same location as he is.Or it may be something like that a user want to send a message(same message) to another 5 users whom he knows.
How can i do that.
I googled may times.I thought web-service can do that job.But i didn't right way to do that.
Can anyone how can i do that with references ???

Best Tutorial (Here u can get All the idea):

Use parse.com
Download the sample app. The sample app works both locally in Android and on the server-side. It does the hardest part for you.
Just modify it to make it fit your needs.
So does anyone know if there is a program that will allow me to track how many times my app is opened daily?
I'm not looking to track the users behavior or anything, I just what stats on the average use of my app.
To know this you need to send information to a server somehow. On the device you would need some kind of library or code that posts this information. On the server you need some service that receives it.
There's a number of tools that let you do that. Analytics tools for example: http://code.google.com/mobile/analytics/docs/
If you don't want to use a pre-made tool you could simply use an HttpClient and you could make a simple Servlet on the server that dumps the use count into a database.
Tow more details:
1- Make sure you ask the user for permission the first time he runs your app. This could be problematic for him because of privacy and bandwith.
2- I would batch this and send it to the server once per day (midnight).
I hope this helps.

If want something easy to implement, you can use http://www.localytics.com/ I've used it for a couple of apps and it works really well.
