My idea is to make an application start automatically when a message from a specific user reaches the inbox of the mobile . For example if my friend sends some numbers to my mobile, the sms has to be read and validated first and then calculator ( inbuilt mobile application) has to be triggered and process the numbers from the message. Please help me with the above query.
I am far from convinced you will be able to give the phone user access to the same sms you use to launch your MIDlet.
You may need to use native development on the phones that support it if J2ME can't give you exactly what you need.
In any case, you probably want to try with J2ME first so you need to read the specifications for JSR-118 and its PushRegistry API, along with JSR-120, which interfaces with SMS.
Most current J2ME-enabled phones will support static SMS Push but you will need to send the SMS to a particular port, much like you would data over a standard library socket.
I don't think you can trigger on just any old SMS message arriving.
This is the class you want to look at, in any case:
javax.microedition.io.PushRegistry

I wanted to build a web-based system using which you will come to know whether the mobile number is registered with WhatsApp or not? It's just to check whether the number entered in textbox have WhatsApp account or not?
I tried finding resources regarding the same but unable to get any solution on it, please share some link for reference so, I can implement it and get to the final result.
You can use the Whatsapp API through Wassenger of Waboxap to send a text message and via webhook service like Loggly determine if the message was delivered. The person will however get a message, which might cause them to block you.
I am planning to create a mobile application for android and ios users, i think i will take a try with xamarin since i will be alone on this project and i don't have a lots of time.
I want that the mobile app for both platform get datas from the api, then if there is new datas available we notify the user by a notification.
How the mobile will work in that kind of project? I mean should i make a background service then check every x seconds/minutes by http request? In that case which time interval? Should i use websockets instead for this case?
The app might be used by many people, so i would to know the scenario in this kind of project: Getting very fast changes, without overload the server due to too many connects or whatever else.
I'm confused about this and i need some lights around, any mobile application/server experiences related would be apprecied!
EDIT:
As suggered by an user, here additional infos:
The api is homemade, restful using JWT made in NodeJS.
Each users on their device should get messages from server asap, even when the app is in background/closed.
Maybe in the future a way to send messages between users themselves.
You have to implement push notification.
It is quite easy to implement this in xamarin. just send the push notification to the device and on the notification received call back send the API request to retrieve the updated data.
Here is the document for sending push notification from custom API.

I'm not a mobile developer, so take this with a grain of salt.
The answer to this really depends on what you're doing, which informs how often to check the API. If it's a messaging app, for example, you could have it check every couple minutes to see if there are undelivered messages, then check more frequently for the next X minutes (to facilitate a conversation in real time).
If it's a GPS navigation app to be used while driving, you'd need much more frequent requests.
As for the API, that also depends on what type of API and the number of requests you can make to it. Is it a commercial API that you get x number of calls per hour on? Is it an API that you built? Etc.
Basically, you need to give more information in order to get more specific answers.
I'm trying to implement some click to dial functionality as follows:
A user finds a number on a webpage (say employee extension)
Clicking that extension will dial a phone number that I've picked
Upon answering that call, I am immediately "conferenced" into
calling the number I actualy wanted to dial.
I've done something very similar using a Twilio API but want to use our corporate Cisco Call Manager capabilities instead of paying per minute for this functionality.
The WebDialerSOAP doesn't seem to be able to give me this functionality. I think doing a conference would work but can't find anything to do that. Possibly an open source call manager wrapper?
why not a FreeSWITCH server alongside the CUCM? It can set up conferences, and it's one of themost programmable products with as much control over API as you want.
It has also an RTMP module, so you can actually run a Flash-based softphone out of your browser
Use TAPI3 or JTAPI
Connect the code using TSP, and Application user
use CreateCall function to the number from HTML page with implementing the trigger.
use CreateCall to the other phone.
use Finish(FINISH_MODE.FM_ASCONFERENCE) to complete conference.
Does anyone know how to send an SMS from the xcode application without using the UI?
I mean I want the SMS to be sent internally from the application. I have seen an app that has this feature.
I have alarm system, the alarm only receive SMS nothing else, I need the user to see the alarm name that is easy, but I want the user to choose the alarm name and control it (close, open) and I need to send command by SMS that the issue, the user should not see the alarm number neither the content which is the command text if you can help me that I will pay anyone that can help me with this.
I'm developing on iOS version 4.2.
no there is no way to do it in background , you have to call the GUI unless you create your api that ask for no & send sms from server.
Can we send SMS programatically by selecting group from the address book using J2me?
yes... it is possible to have access to the users phonebook (if supported on the device(most modern devices do allow it)) via PIM(JSR 75).
And sending SMS's from j2me is also possible(again if the user allows this).
It turns out you can only send a single message to a single recipient at a time using JSR-205.
If you want to send the same message to many recipients, you have to loop around
javax.wireless.messaging.Message.setAddress();
javax.wireless.messaging.MessageConnection.send();
There is no way to add a javax.microedition.pim.ContactList to a Message or to a MessageConnection because there can't be any API dependancy between JSR-205 and JSR-75.
The latest JavaME SDK contains example code that shows how to read contact data in a MIDlet.
