Question

I am wondering with this behavior. In my application I am getting data from server , or my own created database. ( I clone server database)

.replaceAll ( "\r\n" , "<br/>" ) ;

When the data is come from server that it replace. But When data is get from sqlite database its unable to replace the above. As I have try .replaceAll ( "a" , "??" ) ; and its working.

The database data is

Bradley Ambrose is the freelance cameraman who recorded the John Key and John Banks tea meeting.\r\n\r\nHe intentionally placed a black bag with a recording device on the table where Key and Banks were sitting, although he claims it was a mistake, If that were true then how did so many people get a copy of it???\r\n\r\nAlso this guy bloody changed his name from Brad White what the hell is this guy an international man of mystery or something.

I have also debug that issue in detail. But the is not replaced even code is executed the above line successfully.
I have also try

replaceAll ( "\n" , "<br/>" )
replaceAll ( "\r" , "<br/>" ) 

There is debugging picture.

Answer 1

Does the input string contain actual CR and LF characters or pairs of \ and r and \ and n?

The regex won’t work in latter case. It would require .replaceAll("\\\\r\\\\n" , "<br/>")
