Why do many android classes (examples and source) begin with "m"?

Question

I have been looking over some of the android source, and the examples given in the Dev guide, and I notice that many of their classes begin with the letter m, as in the example below:

    // Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};

From this page: http://developer.android.com/guide/topics/ui/ui-events.html

What does the m signify?

Answer 1

The prefix 'm' is a naming convention used to denote private member variables and methods.

Various communities no longer use this convention, but apparently the person(s) who created the android documentation still follow that convention.
