Search the Android documentation for Intents and Activities. It will all be explained over there. — Alex van den Hoogen, Mar 14 '14 at 10:36
you want to pass the intent or you want to fire the intent with startActivityForResult(..)? — drulabs, Mar 14 '14 at 10:36

From your FirstActivity call the SecondActivity using startActivityForResult() method.

Code for first activity

Button button=(Button)findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent=new Intent(CurrentActivity.this,NextActivity.class);
            startActivityForResult(intent, 0);

        }
    });

"0"is the request code

In sec activity

  Intent intent=new Intent();
            setResult(RESULT_OK, intent);
            finish();

Now in your FirstActivity class write following code for onActivityResult() method

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (requestCode == 0) {

 if(resultCode == RESULT_OK){      
     //catch the data if you had sent something from second activity.         
 }
 if (resultCode == RESULT_CANCELED) {    
     //Write your code if there's no result
 }

} }
