Both activities are in the same package
Second activity uses second layout file
setContentView(R.layout.main2);
Errors on this line in the Second_Activity.
EditText text1 = (EditText) findViewById(R.id.EditText03);
Here is the layout file for the Second_Activity.
<?xml version="1.0" encoding="utf-8"?>

I got this same error message when I tried to use TextView.setText passing a char instead of a String. This makes sense since the char would be promoted to an int which meant that I was really calling the
TextView.setText( int resId );
And since there wasn't a resource with that value, it wouldn't work.
