I have a temperature converter app that is on the first screen (activity) and once this is converted using a calculate button, there is a button to take you onto the next screen(activity). then on this screen there is going to be a button which will send a text to someone that shall include the temperature that has been entered on the first screen in both celsius and fahrenheit inside a message such as "the temperature of 5 degrees celsius is 41 degrees in fahrenheit".
How would I go about getting the message to use data entered on the previous screen and then actually to send it to someone in this sort of message form?
thanks
