How to pass variable between activities in Android

I'm trying pass a string variable back to main activity as the text for a button. Anyone has any idea how to do so?

You can use an intent extra. You can read more about intents here: http://developer.android.com/reference/android/content/Intent.html

Off the top of my head, when you create an intent you would want something like this.

//Your first class
Intent myIntent = new Intent (this, NextClass.java);
theintent.putExtra("Awesome Treehouse Guy", "Ernest");
startActivity(myIntent);

//Your second class
String awesomeGuy = getIntent().getStringExtra("Awesome Treehouse Guy");
