Hi,
I have just started developing apps in android and am having problem
with my application, where i am taking text from a textview into a
string and then sending it as SMS.
It worked only twice but later on, i am getting null pointer
exception.. pls check my code below..:
Message sending Method:
public void sendMessage(String phoneNumber, String msg) {
Log.d("Sending message","Message="+msg);
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
//for(int i=0;i<phno.size();i++){
//String phoneNumber=phno.get(i).toString();
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:
Toast.makeText(context,"SMS Sent",
Toast.LENGTH_SHORT).show();
break;
case
SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(context,"Generic
failure",
Toast.LENGTH_LONG).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(context,"No service",
Toast.LENGTH_LONG).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(context,"Null PDU",
Toast.LENGTH_LONG).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(context,"Radio off",
Toast.LENGTH_LONG).show();
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_LONG).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(context,"SMS not
delivered",
Toast.LENGTH_LONG).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, " ", msg, sentPI,
deliveredPI);
}
Method Invocation:
sendMessage("5556", sms);
I am just using it between 2 emulators.
I need your help..
