<p>I want to access public instance variable in main activity from other activity.
And I want to call public method in main activity.
How can I do that?</p>

<pre><code>class MainActivity extends Activity {
    public int i;
    public void myMethod() {}
}

class MyActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // How can I access variable i in MainActivity?
        // And How can I call myMethod() in MainActivity?
    }
}
</code></pre>
