Sending data to Activity without startActivityForResult

How can I send data to another Activity that did not startActivityForResult?

I Override the onActivityResult method in order to perform logic as soon as a result returns from another Activity. Specifically, from my EditItemActivity

Process:

Within my MainActivity,

enter image description here

when I click on an item in the ListView, I am redirected to another Activity called ToDoDetailActivity

enter image description here

When I click the Edit button I am redirector to another Activity called EditItemActivity"

enter image description here

As soon as I make my changes and press the Edit button on the EditItemActivity, I return back to the MainActivity

data = new Intent(EditItemActivity.this, MainActivity.class);
data.putExtra(EDITTEXT_VALUE, etValue);
setResult(123, data);
startActivity(data);

Within my MainActivity, I want to UPDATE the item I just edited with this logic within my onActivityResult method. However, I don't see any logs in LogCat meaning I do not believe this method is being used and therefore no logic is performed

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (data == null) {
            return;
        }
        if (resultCode == 123) {
            String editedItemValue = data.getStringExtra(EditItemActivity.EDITTEXT_VALUE);    
            todoItems.remove(editedPosition);
            aToDoAdapter.insert(editedItemValue, editedPosition);
            aToDoAdapter.notifyDataSetChanged();
        }
    }

We can use BroadcastReceiver or use database to store the result of your edit in EditItemActivity then update that result in onResume method of MainActivity

In your code:

data = new Intent(EditItemActivity.this, MainActivity.class);
data.putExtra(EDITTEXT_VALUE, etValue);
setResult(123, data);
startActivity(data);

When you execute startActivity with MainActivity.class it is launching a new Activity so you are not going to find a result in "onActivityResult" method. It is because you are not returning to the main activity after finishing in a "child" activity.

What I have done in the past is use broadcast event to notify the "MainActivity" about updating the view.

Hope that helps.
