hey i just want to make sure im getting this right, newbie here (only one class in C, now learning java for android)

mFactsTextView = (TextView) findViewById(R.id.factTextView);
        // Ok so this is a confusing one to start out
        // mFactsTextView is a variable we are going to use to pull out the text and slap it on the screen
        // the = is basically making mFactsTextView whatever is on the other side of the = (like a variable in algebra)
        // (TextView) is helping out findViewById because findViewById is normally not used in this location, so its guiding it
        // findViewById is a method, or tool, that is doing the "picking out and slapping onto the screen"
        // R is the common files in java where the normal library is stored, giving the method juice and mechanics 
        // id is saying that its an id we are looking for (be literal) 
        // factTextView is the id we are looking for, and what is to be slapped onto the screen

Overall you seem to have a good grasp. You will learn more as you continue using everything. Here are my two cents.
