Handling onActivityResult in Android app having more than one activity

Question

In my android app, I have a main activity which creates two other sub activites through intent. Now, both the sub activity return result to the main activity. In my main act

Answer 1

It's possible to return any kind of data from a subactivity in the result intent parameter:

Sub-activity:

Intent intent = new Intent ();
intent.putExtra ("string_1", "hello");
intent.putExtra ("string_2", "world");
intent.putExtra ("int_1", 1000);
intent.putExtra ("long_1", 2000l);
activity.setResult (Activity.RESULT_OK, intent);

Parent activity:

@Override
protected void onActivityResult (int requestCode, int resultCode, Intent intent)
{
    if (resultCode == Activity.RESULT_OK)
    {
        String string_1 = intent.getStringExtra ("string_1", "");
        String string_2 = intent.getStringExtra ("string_2", "");
        int int_1 = intent.getIntExtra ("int_1", 0);
        long long_1 = intent.getLongExtra ("long_1", 0);
    }
}
