So i have tried for a long time to find a way to make a app that can send and receive sms in android. That works fine. Here is the code:
For sending:
#SuppressWarnings("deprecation")
public void sendSMS(String phoneNumber, String message) {
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
int unq = 0;
Intent sent = new Intent(SENT);
sent.putExtra("unq", unq);
Intent delivered = new Intent(DELIVERED);
delivered.putExtra("unq", unq);
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, sent, 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,delivered, 0);
// ---when the SMS has been sent---
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
smsstatus = "0";
smserror = "noError";
//sendSmsStatus();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
setSmsstatus("1");
setSmserror("Generic failure");
sendSmsStatus("Generic failure");
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
setSmsstatus("2");
setSmserror("No service");
sendSmsStatus("No service");
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
setSmsstatus("3");
setSmserror("Null PDU");
sendSmsStatus("Null PDU");
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
setSmsstatus("4");
setSmserror("Radio off");
sendSmsStatus("Radio off");
break;
}
}
}, new IntentFilter(SENT));
// ---when the SMS has been delivered---
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
For receiving:
public class SmsReceiver extends BroadcastReceiver {
#SuppressWarnings("deprecation")
#Override
public void onReceive(Context context, Intent intent) {
// ---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
Object sms = "";
ArrayList<String> s = new ArrayList<String>();
Manager m = Factory.getInstance().getManager();
if (bundle != null) {
// ---retrieve the SMS message received---
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]);
str += " SMS fra " + msgs[i].getOriginatingAddress() + "\n";
str += " Besked: ";
str += msgs[i].getMessageBody().toString();
str += "\n";
sms = "SMS = "+msgs[i].getOriginatingAddress()+","+msgs[i].getMessageBody().toString();
s.add(msgs[i].getOriginatingAddress());
s.add(msgs[i].getMessageBody().toString());
}
// ---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_LONG).show();
Manager.toastIt(context, str);
// Send the sms to the server
//Connection.send(new Transmit("SmsReceived",s));
}
}
}
This works great!.
And here comes the question. Is it posible to refactore my code to achive the following:
Have a unique indentifier/flag on my send sms so i can make sure which sms i receive a status on. As you can see i have already tried to put extra on my 2 intents, and maybe that is the right way, but not only do i not now how to check/receive/extract the flag for the status, but also the flag really "unique" right now.
Its nice that I can revieve a sms, but when its more than 160 chars it only shows me the first 160 chars. I had looked at how GTalkSMS does it, but was hoping my code could just be refactored a bit :)
The last problem is, a mix of the 2 above. I cant send a sms thats more than 160 char. I know i have to use sendMultipartTextMessage, but i dont know how. My thought is that i could devide the "String message" by 100 to a Array but i dont know.
So feel free to refactore the code. I'm looking forward to see your replies! :D
Please ask if you need anything explained better or more code! :)
Not Android specific, but read about the "Concatenated SMS" standard. Basically it's multiple messages that each specify they go with the previous one, but it goes over the air as entirely independent SMS.
Most phones hide this fact from the user, of course, but if you're directly receiving SMS it's likely you'll need to deal with it yourself - sending and receiving. Assuming Android uses this standard, which seems like a safe bet.
Since it's so common, I'm sure you can find a library that somebody's already written.
http://en.wikipedia.org/wiki/Concatenated_SMS
Everything you asked for is in the GTalkSMS code (seems you have missed it). :-) But I will point you to the right snippets.
In order to use sendMultipartTextMessage() and distinguish the different sent/delivered notification intents you need first to split the message string via SmsManager.divideMessage(message) and create two, one for sent notifications and one for the delivered notifications, PendingIntents ArrayLists, where, and this is the important part, every PendingIntent has to be created with a a unique request int:
PendingIntent.getBroadcast(context, UNIQUE_ID, deliveredIntent, PendingIntent.FLAG_ONE_SHOT)
This assures that andoird will broadcast an unique intent for every sent delivered notification. You can also add some extras to the intent, which could later tell you for which SMS the notification was.
Code snippets can be found here: sendSMSByPhoneNumber()
Make sure that your SmsReceiver is aware that an incoming intent can contain more that one SMS for multiple senders, but a maximum of nbfOfpdus different senders. The GTalkSMS receiver will sure help you understand how to get this going. :)

I am trying to create a feature in my app which can send SMS to multiple contacts in background. I am using SMS Manager API to do the same. However, everytime RESULT_ERROR_GENERIC_FAILURE returns. I read lot of similar posts on stack overflow and tried all the solutions but none of them seems to work for me. To be specific, I have tried following:
Change phone number format to "+91xxxxxxxxxx", "9xxxxxxxxx", "91xxxxxxxxxx"
Checked the SIM balance
SMS Service centre number is also valid
SMS Message is well within 160 characters
Delay sending multiple SMS
Here is how I am sending SMS:
for (int index = 0; index < contactsList.size(); index++) {
final String phonenumber = contactsList.get(index).getPhone().substring(1);
if (index == 0) {
sendSMS(phonenumber.trim(), sms, contactsList);
} else {
new Handler().postDelayed(new Runnable() {
public void run() {
sendSMS(phonenumber.trim(), sms, contactsList);
}
}, 1000 * 20);
}
}
Here is sendSMS method:
private void sendSMS(String phoneNumber, final String message, final List<MyContactsActivity.ContactsRow> list) {
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, new Intent(
SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0,
new Intent(DELIVERED), 0);
// ---when the SMS has been sent---
context.registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
ContentValues values = new ContentValues();
for (int i = 0; i < list.size() - 1; i++) {
values.put("address", list.get(i).getPhone());
values.put("body", message);
}
context.getContentResolver().insert(
Uri.parse("content://sms/sent"), values);
Toast.makeText(context, "SMS sent", Toast.LENGTH_SHORT).show();
Log.e("Panic", "1");
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(context, "Generic failure", Toast.LENGTH_SHORT).show();
Log.e("Panic", "2");
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(context, "No service", Toast.LENGTH_SHORT).show();
Log.e("Panic", "3");
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(context, "Null PDU", Toast.LENGTH_SHORT).show();
Log.e("Panic", "4");
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(context, "Radio off", Toast.LENGTH_SHORT).show();
Log.e("Panic", "5");
break;
}
}
}, new IntentFilter(SENT));
// ---when the SMS has been delivered---
context.registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(context, "SMS delivered", Toast.LENGTH_SHORT).show();
Log.e("Panic", "6");
break;
case Activity.RESULT_CANCELED:
Toast.makeText(context, "SMS not delivered", Toast.LENGTH_SHORT).show();
Log.e("Panic", "7");
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
Here are my relevant manifest permissions:
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS" />
NOTE: I am testing my app on real device running Android 6. I have checked runtime permissions as well as they are enabled.
Can anyone please tell me what I am doing wrong??
I have found the solution to this problem. In case of dual sim phones, there is an option which specifies from which SIM to send SMS. If option has been set to "Ask everytime", generic failure occurs. Solution is to set this option to either of the SIM card. However, I have not yet found programmatic way to do that.
It is maybe due to a large message. Android supports multipart sms for long messages, Try using multipart sms.
SmsManager smsManager = SmsManager.getDefault();
ArrayList<String> parts = smsManager.divideMessage(message);
smsManager.sendMultipartTextMessage(phoneNo, null, parts, null, null);
(Solution for Flutter)
This solved issue with sending long SMS messages.
In your pubspec.yaml put this:
sms_maintained:
git:
url: https://github.com/andreimc/flutter_sms.git
I found it here: https://github.com/geordyvcErasmus/flutter_sms/pull/15
Your code is correct. check you have active SIM card and having balance in it. Because Generic failure is response from your service provider.
For me the problem was the content of the message, there was special characters (like /r /n)
I got the same problem with same above code
I tried restarted my phone once and try again it worked.
i was using "~" in my message. guess one must sanitize string before sending
I want to send to multiple number of recepients.
I also want to use the built in SMS mechanism without being prompt for a required App (Whatsapp, etc.)
In order to acomplish this, I am using Android's SmsManager.
The for loop iterates through the mobileList array of mobile numbers and send SMS to each one of them, one by one.
The indication for delivered SMS is retrieved by the BroadcastReceiver for the deliveredActionIntent intent.
I am popping a toast with the word "Delivered" and the index number of the message being delivered.
My questions are:
The actual index (idx) is not shown. I get for all toasts the same index number which is the number of mobileList items.
Why is this happening? I expected the index for each mobile by itself.
Is the number of mobileList items limited? Can I have 200 people for instance?
I tested this on a list of 4 mobile numbers but then I got 8-10 toasts. I expected one toast for one mobile delivery.
What is wrong here?
How can I get a notification when all SMSs are delivered? I guess this should be a background action like AsyncTask.
Can someone please show me how to do this?
The code of the SmsManager is shown below.
SmsManager smsManager = SmsManager.getDefault();
for(idx = 0; idx < mobileList.length; idx++) {
String toNumber = mobileList[idx];
String sms = message;
// SMS sent pending intent
Intent sentActionIntent = new Intent(SENT_ACTION);
sentActionIntent.putExtra(EXTRA_IDX, idx);
sentActionIntent.putExtra(EXTRA_TONUMBER, toNumber);
sentActionIntent.putExtra(EXTRA_SMS, sms);
PendingIntent sentPendingIntent = PendingIntent.getBroadcast(this, 0, sentActionIntent, PendingIntent.FLAG_UPDATE_CURRENT);
/* Register for SMS send action */
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String result = "";
switch (getResultCode()) {
case Activity.RESULT_OK:
result = "Transmission successful";
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
result = "Transmission failed";
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
result = "Radio off";
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
result = "No PDU defined";
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
result = "No service";
break;
}
// Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();
}
}, new IntentFilter(SENT_ACTION));
// SMS delivered pending intent
Intent deliveredActionIntent = new Intent(DELIVERED_ACTION);
deliveredActionIntent.putExtra(EXTRA_IDX, idx);
deliveredActionIntent.putExtra(EXTRA_TONUMBER, toNumber);
deliveredActionIntent.putExtra(EXTRA_SMS, sms);
PendingIntent deliveredPendingIntent = PendingIntent.getBroadcast(this, 0, deliveredActionIntent, PendingIntent.FLAG_UPDATE_CURRENT);
/* Register for Delivery event */
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(getApplicationContext(), "Deliverd " + Integer.toString(idx), Toast.LENGTH_SHORT).show();
}
}, new IntentFilter(DELIVERED_ACTION));
//send
smsManager.sendTextMessage(toNumber, null, sms, sentPendingIntent, deliveredPendingIntent);
}
1) idx changes as you run through the for-loop. Thus, each time you toast, you're showing the current value for idx, which is the number of messages being shown. Since you've packed it in your intent, you can simply show the text "Delivered" + intent.getIntExtra(EXTRA_IDX, -1) in your onReceive method.
2) I'm not sure what you're asking.
3) I'm not sure off-hand, and can't currently debug.
4) You're going to have to keep track of which indices you've received. A HashSet<Integer> should do the trick.
Above your for loop, add this:
final HashSet<Integer> undelivered = new HashSet<Integer>();
In your for loop, add this:
undelivered.add(idx);
To answer your questions for 1, 3, and 4 at once, change your onReceived body to this:
// Get the index from the intent
int idx = intent.getIntExtra(EXTRA_IDX, -1);
if (undelivered.contains(idx)) {
// This index is now delivered. We remove it from the undelivered set, and Toast that it was delivered.
undelivered.remove(idx);
Toast.makeText(getApplicationContext(), "Delivered " + idx, Toast.LENGTH_SHORT).show();
if (undelivered.isEmpty() {
// We've delivered all of the messages ...
Toast.makeText(getApplicationContext(), "All messages were delivered.", Toast.LENGTH_SHORT).show();
}
}
I am sending SMS through my application using a very common way that is explained in pretty much all tutorials. I use sendMultipartTextMessage with "sent Intents" and "delivery Intents", then a Broadcast receiver listen for the results and print things.
But, everytime I try to send a SMS, even with something like 10 characters, I always get a "Generic failure".
My default SMS app is working perfectly and I can send/receive SMS/MMS without any troubles so it can't be a network issue. I don't want my app to become my new default SMS app, I just want it to be able to send a short SMS sometimes.
I tried a lot of things but everything has failed.
What is that issue and what can I do to get rid of it ?

The second parameter in the SmsManager#sendMultipartTextMessage() method (as well as the sendTextMessage() and sendDataMessage() methods) is for the number of your service center, not the sender's number. A service center is the part of your network that handles the storage, routing, and delivery of SMS messages, so passing an invalid number would result in the generic failure status you're getting. You simply need to pass null for this.
I am sending perhaps 100-200 SMS messages
The DELIVERED status comes back in dribs and drabs so
I need to get the recipient address to see which message it refers to.
I see whilst debugging the data I can see it there in
message.mWrappedSMSMessage.recipientAddress.address the value is correct but how can I read this??
registerReceiver(new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent arg1) {
Bundle bundle = arg1.getExtras();
if (bundle != null){
Object pdu = (Object) bundle.get("pdu");
SmsMessage message = SmsMessage.createFromPdu((byte[]) pdu);
String str = message.getServiceCenterAddress();
String str = message.getOriginatingAddress();
//---retrieve the SMS message received---
switch (getResultCode())
{
case Activity.RESULT_OK:
sms_log(str+ " SMS delivered");
break;
case Activity.RESULT_CANCELED:
sms_log(str+ " SMS not delivered");
break;
}
}
}
}, new IntentFilter(DELIVERED));
the above code allows access to
message.getServiceCenterAddress() and message.getOriginatingAddress() but how do I get the message recipient address.
I see whilst debugging the data is there in
message.mWrappedSMSMessage.recipientAddress.address the value is correct but how can I read this??

OK. I am sending text messages through my app. After a text message is sent, it sends a status update to a server. This portion works okay, but the problem I am running into is twofold. I am not sure if they are related, but I assume that they are.
My app has the ability to send a single text to multiple users. Here is a sample of the code...
if(phoneNumbers.length > 0 && message.getText().toString().equals("") == false)
{
for(int i=0;i<phoneNumbers.length;i++)
{
sms = SmsManager.getDefault();
try
{
sms.sendTextMessage(phoneNumbers[i], null, message.getText().toString(), null, null);
sentQuantity++;
}
catch(IllegalArgumentException e)
{
}
}
}
Basically, it just loops through an array of phone numbers, and sends the text one at a time. Here is where part of my issue lies. If I choose 3 or more numbers to send the text to, sometimes not all of the texts actually get sent. It happens very randomly.
I assume it is because there is a delay between sending each individual message, but the code doesn't wait long enough. I reached this assumption because if I step into the program using eclipse and manually go through the app, everything always works just fine.
My other issue is when I send off the text message status update to a web server.
Immediately after the text messages get sent, the app then connects to the internet and tells the server via an http post the number of texts that were sent. Here is my snippet of internet code...
for(int i = 0; i < postNames.length; i++)
{
nameValuePairs.add(new BasicNameValuePair(postNames[i], postValues[i]));
}
//http post
try{
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 10000;
HttpConnectionParams.setConnectionTimeout(httpParameters,timeoutConnection );
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(webAddress);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
This section just compiles the items for the post, connects to a web page, and sends the post. The key here is the 10 second connection timeout. Once again, like I said earlier, the internet connection happens immediately after sending the texts. So, if I go into debug mode and manually step through the process, everything works fine. But if I just run the app on my phone, I will get a connection time out error.
Now, I am hoping that if I can reduce the number of text messages to one single text, regardless of the number of recipients, that would be awesome. I have tried separating the phone numbers with a comma, and that didn't work. I also tried separating the numbers with a semi-colon (exactly like how Microsoft Outlook, or GMail lets you add multiple recipients to an email). None of those worked for me. Does anyone have any suggestions? Even if there is a different approach altogether, that would be appreciated. Oh, and I don't want to use the Google Messaging intent to send the messages, I need to use my own app.
You actually need to send the next sms after the previous one is sent, for this you need to check the status of the sms sent, please see this tutorial, it says:
If you need to monitor the status of the SMS message sending process, you can actually use two PendingIntent objects together with two BroadcastReceiver objects, like this:
//---sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
//---when the SMS has been sent---
registerReceiver(new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
//---when the SMS has been delivered---
registerReceiver(new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
I guess this is what u need.
The below snippet provides to to enter long message and divide them into part and send each of it individual to a given contact or even for a group of contacts
public void sendLongSMS() {
String phoneNumber = "0123456789";
String message = "Hello World! Now we are going to demonstrate " +
"how to send a message with more than 160 characters from your Android application.";
SmsManager smsManager = SmsManager.getDefault();
ArrayList<String> parts = smsManager.divideMessage(message);
smsManager.sendMultipartTextMessage(phoneNumber, null, parts, null, null);
}
First you must add permission in AndroidManifest.xml file
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
then write this code
try {
String ph="1234568790";
String msg="Haiii friend";
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(ph, null,msg, null, null);
Toast.makeText(MainActivity.this, "Message Sent",
Toast.LENGTH_LONG).show();
}
catch (Exception e)
{
Toast.makeText(MainActivity.this, "Message not Sent",
Toast.LENGTH_LONG).show();
}
You can try this
SmsManager.getDefault().sendTextMessage(phoneNUmber, null, messageToSend, null, null);
Thanks
