[Idea] Callback with ParseException

[ghost]

Hi,

I think it could be a good idea if for maybe most of functions (signup, reset password, cloud codes functions, etc.), we can have a callback with firstly the object(s) and secondly the ParseException, like this example (from the official docs: https://docs.parseplatform.org/android/guide/#retrieving-objects) :

ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereEqualTo("gender", "female");
query.findInBackground(new FindCallback<ParseUser>() {
  public void done(List<ParseUser> objects, ParseException e) {
    if (e == null) {
        // The query was successful.
    } else {
        // Something went wrong.
    }
  }
});

And

ParseUser.requestPasswordResetInBackground("myemail@example.com", new RequestPasswordResetCallback() {
  public void done(ParseException e) {
    if (e == null) {
      // An email was successfully sent with reset instructions.
    } else {
      // Something went wrong. Look at the ParseException to see what's up.
    }
  }
});

With this, if we sign up a user and there is an error, we know which error is because for the moment, we can't know why it fails.

Okay so this is definitely something we can do. I did originally take this approach but then removed it as it added a lot of boiler plate code... however, after writing my own app using this library, I do feel that it's something that is needed.

This will be a breaking change but will be added.

I'm not 100% when the ParseUser queries will be added, but a ParseResponse object can be the return type for a ParseUser request.

You were correct in this idea and this has now been implemented. It's on the develop branch and will be released with 1.0.6.

If you check the updated example code, there's now examples of the user being returned as a ParseResponse which contains user and exception details. There's also a working example of a query based on a user.
