This is Blog about Android Intent how to work with android Intent. in this Example i take one example in which we pass two value one Activity to another Activity through Intent. to Be Ready.

Take One New Project
you must take 2 layout , and 2 java class file.

type Bellow Code to Your Project
package com.drc.sharedpre;
