I have this latex code. But when I try to compile it it gives me an error saying :
! LaTeX Error: Something's wrong--perhaps a missing \item.See the
LaTeX manual or LaTeX Companion for explanation.Type H for
immediate help....
This error is on line:
\end{quotation}
Why am I getting this error? I haven't added any \item on the line where I'm getting the error.

Answer 1

The \paragraph and \\ instructions in the quotation do not make much sense. I guess that you meant something like this:
\begin{quotation}
\noindent
Banks are providing mobile applications to their customer. We are developing a
banking application using \emph{Location Based Encryption}. Compared to current
banking applications, which are location independent, \ldots
\paragraph{Keywords:} bank, application, encryption, location, mobile.
