Answer 1

I've had success subclassing AsyncTaskLoader and making a few tweaks to its methods.

public class FixedAsyncTaskLoader extends AsyncTaskLoader {

    private D result;

    public FixedAsyncTaskLoader(Context context) {
        super(context);
    }

    @Override
    protected void onStartLoading() {
        if (result != null) {
            deliverResult(result);
        } else {
            forceLoad();
        }
    }

    @Override
    public void deliverResult(T data) {
        result = data;

        if (isStarted()) {
            super.deliverResult(result);
        }
    }

    @Override
    protected void onReset() {
        super.onReset();
        onStopLoading();

        result = null;
    }

    @Override
    protected void onStopLoading() {
        cancelLoad();
    }
}
