Question

How to send big SMS in android. I used :

SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(contactNos[j], null,msgs[i], sentPI, deliveredPI);

this code work only for 160 character message. i also use

ArrayList<String> msgsplit=sms.divideMessage(msgs[i]);
ArrayList<PendingIntent> listOfIntents = new ArrayList<PendingIntent>(); 

for (int k=0; k < msgsplit.size(); k++){  
    Intent sentIntent = new Intent(); 
    PendingIntent pi = PendingIntent.getBroadcast(MultipleMsg.this, 0, sentIntent, PendingIntent.FLAG_CANCEL_CURRENT);  
    listOfIntents.add(pi);  
}
// sendMessage(contactNos[j],msgs[i]);
sms.sendMultipartTextMessage(contactNos[j],null,msgsplit, listOfIntents, null);

But it sends junk character in the message.
Can anyone help me?

Junk characters? method sendMultipartTextMessage only send text message. If you want to send non text message, you should look to method sendDataMessage. Below is the code excerpt from android cts. It has example on how to send long messages.

SmsManager sm = SmsManager.getDefault();
ArrayList<String> parts =sm.divideMessage(LONG_TEXT);
int numParts = parts.size();

ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();

for (int i = 0; i < numParts; i++) {
sentIntents.add(PendingIntent.getBroadcast(getContext(), 0, mSendIntent, 0));
deliveryIntents.add(PendingIntent.getBroadcast(getContext(), 0, mDeliveryIntent, 0));
}

sm.sendMultiPartTextMessage(mDestAddr,null, parts, sentIntents, deliveryIntents)
