Alright, here I am again. Still learning. Now I need to pass integer values back and forth from 2 activities. First activity passes a counter value to the second (which k

Answer 1

Do like this

startActivityForResult(i, 100);  

For setResult

setResult(RESULT_OK);

You can use setresult for more advanced sending of results something like

intent = new Intent();
intent.putExtra("key", "I am done");
setResult(1001, intent);

And in onActivityResult

protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
   if(requestCode == 100)
   {
    String key = data.getStringExtra("key");
    if(resultcode == 1001 && key!= null && key.equals("I am done"){
       //do something
    }else{
       //do something else
    }

   }
} 

You dont have to use setResult, if all you need to check is whether you returned from the activity then dont set it and dont check in onActivityResult
