[android] How to pass data from 2nd activity to 1st activity when pressed back? - android

Other answers were not working when I put setResult in onBackPressed. Commenting call to super onBackPressed and calling finish manually solves the problem:

@Override
public void onBackPressed() {
    //super.onBackPressed();
    Intent i = new Intent();
    i.putExtra(EXTRA_NON_DOWNLOADED_PAGES, notDownloaded);
    setResult(RESULT_OK, i);
    finish();
}

And in first activity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == QUEUE_MSG) {
        if (resultCode == RESULT_OK) {
            Serializable tmp = data.getSerializableExtra(MainActivity.EXTRA_NON_DOWNLOADED_PAGES);
            if (tmp != null)
                serializable = tmp;
        }
    }
}
