setResult does not work when BACK button pressed

Question

I am trying to setResult after the BACK button was pressed. I call in onDestroy

Intent data = new Intent();
setResult(RESULT_OK, data) 

But

Answer 1

You should override onOptionsItemSelected like this:

@Override
public boolean onOptionsItemSelected(final MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home:
        final Intent mIntent = new Intent();
        mIntent.putExtra("param", "value");
        setResult(RESULT_OK, mIntent);
        finish();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}
