startActivityForResult

From your FirstActivity call the SecondActivity using startActivityForresult() method

eg:

Intent i = new Intent(this, SeconActivity.class);
startActivityForResult(i, 1);

In your SecondActivity set the data which you want to return back to FirstActivity, If you don't want to return back don't set any.

eg: In secondActivity if you want to send back data

 Intent returnIntent = new Intent();
 returnIntent.putExtra("result",result);
 setResult(RESULT_OK,returnIntent);     
 finish();

if you don't want to return data

Intent returnIntent = new Intent();
setResult(RESULT_CANCELED, returnIntent);        
finish();

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

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

if (requestCode == 1) {

     if(resultCode == RESULT_OK){

      String result=data.getStringExtra("result");

}

if (resultCode == RESULT_CANCELED) {

     //Write your code on no result return 

}
}//onAcrivityResult
