Switch author and title in beamer bibliography

Question

When I include references in a beamer frame, the author is printed first, followed by the title, followed by the journal/note. I'm using bibtex for referencing.

    \bibliographystyle{unsrt}
    \bibliography{report.bib} 

The output looks as follows:

How can I make the title appear on top, followed by the author underneath?

I have been looking at beamerbaselocalstructure.sty to redefine the newblock definition, but have been unsuccessful so far.

Here's sample code that results in the output above (although it uses inline bibitems instead of bibtex). I do not want to switch the author and title field in the bibtex file.

\documentclass{beamer}

\begin{document}
\begin{frame}

    \begin{thebibliography}{10}
        \bibitem{patchdroid} Collin Mulliner, Jon Oberheide, William Robertson, and Engin Kirda. \newblock  Scalable Third-Party Security Patches for Android Devices. \newblock In \textit{Proceedings of the 29th Annual Computer Security Applications Conference}, pages 259--268. ACM, 20143.
    \end{thebibliography}

\end{frame}
\end{document}

Answer 1

I managed to redefine \beamer@newblock so that the text in the author block is saved and then later used after the title block. I used the definition of the command in beamerbaselocalstructure.sty (Till Tantau, Vedran Miletić) as the starting point for my modifications. Note that the bibliography entry author template is now used for the title and the title template is used for the authors.

Anyone with better LaTeX skills is welcome to improve the solution.

\documentclass{beamer}

\usepackage{xparse}
\makeatletter
\RenewDocumentCommand\beamer@newblock{u{\newblock}}{%
  \def\newblock{%
    \usebeamercolor[fg]{bibliography entry title}%
    \usebeamerfont{bibliography entry title}%
    \usebeamertemplate{bibliography entry author}%
    \def\newblock{%
      \usebeamercolor[fg]{bibliography entry author}%
      \usebeamerfont{bibliography entry author}%
      \usebeamertemplate{bibliography entry title}%
