android hide special SMSs notification from user and remove it from inbox

My application uses some web services for performing actions in server and getting results from it. Now I want my app to work in offline mode. I have a sms panel that can handle sending and receiving messages to clients. So the thing I need is to listen to messages in client and respond to it if it has a special format. I know how to listen to incoming sms from code, here it is:
public class SmsReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// ---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
Log.d("checking", "sms received!");
String str = "";
if (bundle != null) {
// ---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
String sender = null;
String body = null;
for (int i = 0; i < msgs.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
sender = msgs[i].getOriginatingAddress();
str += " :";
str += msgs[i].getMessageBody().toString();
body = msgs[i].getMessageBody().toString();
str += "\n";
}
// ---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
}
}
}
and it works properly. The thing here is I don't want my special messages appear in user inbox or even hide sms notification from him. Is this possible? Should I listen to all incoming messages?
update:
I assume that things are different in KitKat so any solution works in api 19 appreciated.
thanks in advanced.

Try abortBroadcast(); in your BroadcastReceiver
if (intent.getAction().equals(android.provider.Telephony.SMS_RECEIVED)) {
abortBroadcast();
}
i don't know if this works on KitKat or not.

android - string doesnt set off if condition but log output suggests it should

So im making an app that uses sms to send data between two devices and am trying to get one to automaticly respond to the other. But the string getMessageBody() is returning isnt setting of the if statment to send the automatic message even tho the log output "(test)" seems to match the condition. I have added extra text to either side of the string in the log message to check for whitespace. Thanks in advance.
The code sending the message to be received.
SendSMS(inputNum.getText().toString(),"test");
The receiver code
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
if(bundle != null)
{
Object[]pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for(int i = 0;i < msgs.length;i++)
{
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
originNumber = msgs[i].getOriginatingAddress();
messages = msgs[i].getMessageBody();
Log.e("Received Text", messages);
}
if(messages == "test")
SendSMS(originNumber, "auto send");
else
Log.e("else Text", "("+messages+")");
}

if(messages == "test")
String comparison in java need the equals method. With the == you will compare the address of message with the address of "test". Since those are differente String object the result will be false. Change it in:
if(messages.equals("test"))

Android MultiPartTextMessages

I'm having trouble receiving multiPartTextMessages.
My application divides and then sends messages part by part.
However, whenever a part is coming broadcastreceiver works.
I need to combine this part to get the original message.
How can I do it?

put a special text at the start of every part like #myTag_msg1_part1. In broadcast receiver check the special text of every message to know the partno, then accordingly you can join them.

This should help
#Override
public void onReceive(Context context, Intent intent) {
Log.d(ClassName, "received SMS");
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
// here is what I need, just combine them all :-)
final SmsMessage[] messages = new SmsMessage[pdus.length];
Log.d(ClassName, String.format("message count = %s", messages.length));
for (int i = 0; i < pdus.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
}
}// onReceive()

Listen to incoming multipart SMS message

I can catch newly incoming SMS messages. But if that is a multipart message, my broadcast receiver receives all parts of the message at several times.
Is there a way to receive the whole message at one time - like default messaging app does?

Holy...!
After reading the Android source (this file), I realize that this is such a stupid question...
Here is my receiver:
#Override
public void onReceive(Context context, Intent intent) {
Log.d(ClassName, "received SMS");
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
// here is what I need, just combine them all :-)
final SmsMessage[] messages = new SmsMessage[pdus.length];
Log.d(ClassName, String.format("message count = %s", messages.length));
for (int i = 0; i < pdus.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
}
}// onReceive()
Oops... I was too lazy to look at my code. I already got all parts of the message at a time.

Android - receiving long SMS (multipart)

I have an application, which has to listen for specific SMS. So far easy.
But when I receive the message, it's multipart. Is there a proper way to receive the SMS as one message?
Now my activity starts two times, for each part of the sms. Should I concatenate the SMS by hand?

It may be useful to look at how gTalkSMS handles incoming SMS'es, as it appears to handle multipart messages correctly.

Bundle bundle = intent.getExtras();
Object[] pdus = (Object[]) bundle.get("pdus");
messages = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++)
{
messages[i] =
SmsMessage.createFromPdu((byte[]) pdus[i]);
}
SmsMessage sms = messages[0];
try {
if (messages.length == 1 || sms.isReplace()) {
body = sms.getDisplayMessageBody();
} else {
StringBuilder bodyText = new StringBuilder();
for (int i = 0; i < messages.length; i++) {
bodyText.append(messages[i].getMessageBody());
}
body = bodyText.toString();
}
} catch (Exception e) {
}

Shorter solution:
if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
Bundle bundle = intent.getExtras(); //---get the SMS message passed in---
SmsMessage[] msgs = null;
if (bundle != null) {
//---retrieve the SMS message received---
try {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
String msgBody = "";
String msg_from = "";
for (int i = 0; i < msgs.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
msg_from = msgs[i].getOriginatingAddress();
msgBody += msgs[i].getMessageBody();
}
} catch (Exception e) {
// Log.d("Exception caught",e.getMessage());
}
}
}

Yes you should concatenate the SMS by hand, but obviously you don't want to be starting up a new activity for each message segment.
I suggest setting your Activity's launchMode attribute to singleTask or singleInstance so that that doesn't happen.
Alternatively have your SMS's received by a Service, which will fire up a new Activity only once it has a complete message.

I am not aware of a way to recive a multipart message as once. But if you have the right intent-filter setup you get only one Intent for more than one SMS. In fact, the Intent can contain SMS from different senders and/or zero or more multipart SMS .
You could try this approach:
Add an SmsReceiver Class with intent-filter android.provider.Telephony.SMS_RECEIVED in the Manifest.
The classes onReceive Method will get an intent with a bundle of pdus. These pdu's can origin from different senders each and/or there can be more pdus from the same sender in case of a multipart text message, which you have to concatenate.
