Have no bibliography result

Question

I'm using TeXstudio and trying to list the bibliography content in the document. I compiled the .tex file and there is no errors but I got no output.

\documentclass[12pt]{article}

\usepackage{filecontents}
\usepackage[style=authoryear, backend=bibtex]{biblatex}

\newenvironment{subs}
  {\adjustwidth{2em}{0pt}}
  {\endadjustwidth}

\begin{filecontents}{sample.bib}

\bibliography{sample}




\begin{document}

\nocite{*}
\printbibliography

\end{document}

I tried so many proposed solutions but unfortunately nothing worked

biblatex uses \addbibresource{sample.bib}. Try that instead of \bibliography{sample}. — Werner, Jan 19 '17 at 07:00
@DavidCarlisle - Not sure I follow you. The OP's code does feature the instruction \usepackage[style=authoryear, backend=bibtex]{biblatex} — Mico, Jan 19 '17 at 07:56
I've taken the liberty of removing all exclamation marks from your posting. No need to shout, really. We're not deaf. — Mico, Jan 19 '17 at 08:13
If I use biber instead of bibtex, there is no issue, nor there is with bibtex if I add another set of braces like publisher={{...}}. On the other hand, the publisher field is not used for the @article type, so removing it seems to be a good idea. — egreg, Jan 19 '17 at 08:18
@CarLaTeX It should make no difference if one uses \addbibresource or \bibliography in this case. But note that the file extension is mandatory with \addbibresource, so it should be \addbibresource{sample.bib}. — moewe, Jan 19 '17 at 08:28
You have tagged your question with Biber, but your code uses backend=bibtex, so you have to run BibTeX and not Biber. You should switch to backend=biber and run Biber, see here for help in getting biber to run in your favourite editor. Note also that normally, the publisher field does not contain the full address of the publisher, there is the location field for the city of the publisher. But, as egreg noted, the publisher field is ignored for @articles anyway. — moewe, Jan 19 '17 at 08:30

@samcarter It still haven't solved yet. The last solution I did is to use the online editor but the local editor still has the problem. Thank you — F 505, Apr 26 '17 at 23:47
@F505 Maybe it then would be good to give some feedback to the answer you received? — samcarter_is_at_topanswers.xyz, Apr 27 '17 at 07:45

It would be helpful if you were a bit more specific as to which proposed solutions you've tried.

I don't have TeXstudio on my computer, so I can't judge what your front-end is doing. When I run your code from TeXworks as the front-end and MacTeX2016 as the back-end, I do notice that biblatex issues complaints about "too many commas" in the publisher field of the entry awad2011machine. If I change the field named publisher to xpublisher in all entries and re-run your code, I get no more warning messages.

That said, you should make more of an effort to make sure that the contents of all entries are correct. A quick glance over your code immediately shows incorrect capitalization and failure to prevent lowercasing of words by BibTeX.

Here's the output of applying some judicious corrections to your code -- note that I've also replaced \bibliography{sample} with the more idiomatic \addbibresource{sample.bib}:
