I'm trying to create a simple app to send and receive binary messages
between phones. I'm using an EditText to get the message and I have
hardcoded my phone number in for testing on my phone for now. The
function call looks something like:
sms_manager = SmsManager.getDefault();
try {
sms_manager.sendDataMessage(MY_NUMBER, null, (short) SMS_PORT,
msg.getBytes(), piSend, piDelivered);
} catch(NullPointerException e) {
((TextView)findViewById(R.id.error)).setText("NullPointerException
caught");
}
When I run it on a virtual device nothing happens but I don't get an
error (I can make a working text version of this which works on the
phone and also does nothing on the virtual device). Every time I run
it on my phone it throws the NullPointerException without getting to
either of the PendingIntent objects (which make a Toast). When I
debug it in eclipse it seems that ISms$Stub$Proxy.sendData() is
generating the NullPointerException. I haven't been able to figure
out what that means exactly but I have read elsewhere that this
function works on GSM phones and throws a NullPointerException on CDMA
phones. I am testing on a CDMA Droid2 Global. Does anyone know if I
am doing something wrong if this function just doesn't work with
CDMA? Any suggestions for a workaround?
Thanks,
Brandon
