you can do it in two ways using     Serializable Parcelable      This examle will show you how to implement it with serializable    class Customer implements Serializable         properties  getter setters  amp  constructor       This is your custom object Customer customer   new Customer name  address  zip    Intent intent   new Intent    intent setClass SourceActivity this  TargetActivity this   intent putExtra  customer   customer   startActivity intent       Now in your TargetActivity Bundle extras   getIntent   getExtras    if  extras    null        Customer customer    Customer extras getSerializable  customer           do something with the customer     Now have a look at  this   This link will give you a brief overview of how to implement it with Parcelable     Look at  this    This discussion will let you know which is much better way to implement it   Thanks
