Yes there is a way, but unfortunately since the rollout of KitKat it isn't that easy any more. To work on versions > Jelly Bean you must have your application run as the default SMS application, that is to modify and abortBroadcast(). For 4.3 and below, create a broadcast receiver and do something like the following:
public void onReceive( Context context, Intent intent ) {
// Get the SMS map from Intent
Bundle extras = intent.getExtras();
String messages = "";
if ( extras != null ) {
// Get received SMS array
Object[] smsExtra = (Object[]) extras.get( SMS_EXTRA_NAME );
// Get ContentResolver object for pushing encrypted SMS to the incoming folder
ContentResolver contentResolver = context.getContentResolver();
for ( int i = 0; i < smsExtra.length; ++i ) {
SmsMessage sms = SmsMessage.createFromPdu((byte[])smsExtra[i]);
String body = sms.getMessageBody().toString();
String address = sms.getOriginatingAddress();
// Here is where you modify the body of the message!
messages += "SMS from " + address + " :\n";
messages += body + "\n";
putSmsToDatabase( contentResolver, sms );
}
}
}
private void putSmsToDatabase( ContentResolver contentResolver, SmsMessage sms ) {
// Create SMS row
ContentValues values = new ContentValues();
values.put( ADDRESS, sms.getOriginatingAddress() );
values.put( DATE, sms.getTimestampMillis() );
values.put( READ, MESSAGE_IS_NOT_READ );
values.put( STATUS, sms.getStatus() );
values.put( TYPE, MESSAGE_TYPE_INBOX );
values.put( SEEN, MESSAGE_IS_NOT_SEEN );
try {
values.put( BODY, sms.getMessageBody() ); // May need sms.getMessageBody.toString()
}
catch ( Exception e ) {
e.printStackTrace();
}
// Push row into the SMS table
contentResolver.insert( Uri.parse( SMS_URI ), values );
}
