[android-developers] Sending a SMS with BroadcastReceiver

Hello everyone, 

I have the problem, that I can send a SMS within my BroadcastReceiver - class. However, it is always the same message that will be sent.

The app has some buttons and one numberpicker.

As soon as the first number is being picked a second class ( BroadcastReceiver - class ) is being triggered. 

No, if the user wants to send a new message, he or she picks another number the same message will be sent and I do not know why?!

I have already tried to remove the key in the intent but nothing helps me.

Maybe, someone could help me, please?

Thank you very much!

BR,

Bernd
