xml - Merge two Android projects so that both will appear on layout -

i have android project 2 modules.

one banner advertisement , other application.

how merge these projects banner ad show on every xml layout of project?

i think best way creating baseactivity extends activity. create banner adview java code. extend baseactivity other activities using.

here's sample code baseactivity

import android.app.activity; import android.os.bundle; public class baseactivity extends activity {     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         createbanner();     }      void createbanner() {         //handle banner creation here     } } 

if using fragments navigations have declare banner inside activity's layout xml
