sorry fo my complete ignorance developing an Android.
I'm asking about the feaseability of this pseudocode I would like to implement as native app; let imagine a task that:
when a specific SMS arrive (only those sent from a specific sender number)
possibly (multi-SMS in case of text bigger than 160 chars )
elaborate/format each received SMS:
. save text content on a local db
. print text on a bluetooth printer
. reply to sender with some sort of "ACK" SMS
BTW, what above could be sort of background task, and I would need on foreground a sort of user interface that visualizes received SMS and do some user actions (sending back SMS to sender)
Is all that possible on Android ? Any issue ?
I mean, above all: is possible to "catch" specific SMSs (by example those sent by a specific sender number), living unalterated the usual SMS workflow for ALL other SMSs ?
Sorry for my beginner question and Thanks for your patience

Following this link to implement a BroadcastReceiver that will listen for incoming SMS.
Inside your onReceive from your BroadcastReceiver, handle your logic (print/save/..)
It is possible, yes. But not recommended. That being said the way to set this up is to catch the SMS intent, so your app would be started when an SMS is received. Otherwise it would not run at all (as long as you don't have any other interface open). For a code example on the message interception part, see this post. For the database part look up local storage on android phones. Look up on SMS messaging for the reply. Not sure how bluetooth printing would work as I've never done it, but if it's a standard protocol I'm sure there's either built in support or a library for it.

I was wondering if it's possible to modify the SMS before sending it in Android, but not only if it's send by my application, but also if it's being send by other applications. My application would work in the background and wait for an sms sending, and when that occurres it prevents it from doing so, modifies it and sends it.
For example, a default SMS application(built-in or otherwise) sends an sms to someone and I want to catch it before it does, modify the body(like add new receiver or some text inside message itself).
I think that this: Can I modify sms_body before sending SMS with built-in SMS Application? might be an answer to my question, but I'm not sure, and it's kind of old.
Let me know if I was unclear in something. Thanks.
Let me try with simple example-
Its just like you have an Account in a Bank and you wish all deposit should come in your Account. Here Account refers to your App and Bank refers to your Mobile device.
In a short, you can't achieve this on a non-rooted device. Yes that is possible on non-rooted device if user like to send his messages from your App, then surely you can modify messages written by user.
not only if it's send by my application, but also if it's being send by other applications
This is not possible, except perhaps on rooted devices.
I’m trying to develop an application to do some manipulation (compression and security matters) on the outgoing Sms regardless of the composer application. The main challenge is that I cannot capture the Sms exactly before being sent. For instance the user compose the message body using Go Sms Pro and when the send button is pressed , right before the sms is actually sent we capture it and do the compression and security matters on .
Any solution or replacement idea appreciated.
Starting with KitKat, the SMS content provider has been opened up (finally): http://developer.android.com/about/versions/android-4.4.html
To make this work with previous versions of android, you could set up a content observer to watch content://sms/, query the appropriate tables in that database, and then do whatever you like to erase the message before it goes out. This is just a thought mind you, but whatever you do will likely involve using this method.
This is not possible, short of via your own custom build of the Android OS. You have no ability to intercept, let alone modify, the calls from an arbitrary app via SmsManager to the OS to send an SMS message.
Is there any possibility to trigger an action on Android?
Like if we send a message to an android phone, it should execute some instruction, like running an app or something.
Is it possible with Android? Or iOS?
Or can the event be anything like reception of an email or phone call from a specific number or anything that can be done remotely?
Something as shown in the link here. But I want to know how to program these triggers.
Can someone help me out, please?
I want to manipulate the network settings so that it can automatically switch on the Wi-Fi or data and send back some data. Is that possible?
Yes you can trigger an action on android.
For that, you need to use a broadcastreceiver (here is a good article about how to use it http://www.vogella.com/articles/AndroidBroadcastReceiver/article.html)
Here is a simple example of the source code in order to display a message to the user when a sms is received.
http://androidsourcecode.blogspot.ch/2010/10/receiving-sms-using-broadcastreceiver.html
I've got an idea for an Android Application, however I am unsure if it would work. Essentially what I want to do is "intercept" all text messages sent from any SMS App and make modifications to them.
For example, say I write out the following SMS:
Hi {Name}, how are you today? Can you tell {Boss} I'll be 15 minutes late today.
The onSMSSend function in my application(assuming it is currently running in the background) would then be able to edit the content of the message(Eg. Replacing variables with ones defined in the application), and then send it on to the recipient.
Is Android able to provide this functionality?
No it is not. Android may be able to inform you after an SMS was send. But there is no way to intercept a message that should be sent and apply changes to it on a non rooted phone.
What you could do is to write a new messaging App that allows the user to type a message, choose a number and send the message. Now you have full control over the message that is send but building a replacement for the sms app is a fair amount of work.
Is there a way to intercept an SMS with BroadcastReceiver as for example here
but without showing any notifications to the user and immediately deleting the message that contains for example some keyword
EDIT:
What I need is to have some communication between android phones, one to one, and I thought that sending SMS messages would solve the problem, but the SMS notification are not needed for that, maybe the WAP PUSH messages would better for that but I have no idea how to send them from android phone.
If someone has any idea that would help, please put it here :)
Some guys from the Ericsson lab presented their push solution during the droidcon this year (with some additional reasoning why push is good).
Here's the link to their site:
https://labs.ericsson.com/apis/mobile-java-push/blog/push-android-droidpush-droidcamp
I would recommend PUSH or a web service to do the task your requesting.
WAP is a SMS message with a URL, it's goal is to allow users to download content from the web, kinda like a MMS message but for phones without MMS capability. Usually it's a premium message (Meaning the end user pays for these).
As for SMS, I don't think you can delete these from the phone without the knowledge of the user. Think legal on this. Would you want to receive and send SMS messages without your knowledge? SMS can also bill your phone so I'm thinking legally I would recommend avoiding this.
Another note if you're going to use SMS is that you would need a short code and a aggragator. Even if you have the short code and aggragator you still need the users permission to send reoccurring messages to their phone via application/phone.
I would recommend these links for reading:
Android Push Notification
http://www.anddev.org/calling_a_web_service_from_android-t348.html
Web Services
Yes, you could intercept Android SMS without notification icon.
Here is the solution: Can we delete an SMS in Android before it reaches the inbox?
check out Xtify - similar to C2D for Froyo with the ability to push intents but, Xtify does a lot more and does it across Android, iPhone and Blackberry.
xtify uses an SDK for easy implementation and has a web console and web service to configure messages to one, some or all of your users.
you can create rules that determine when a message gets sent – you can even push notifications using location as the trigger as the SDK runs in the background and provides access to persistent location.
