You should try the .replace("\", "") function. Otherwise you can try str.replaceAll("\'\", ""); using '\' as the escape sequence.

Neither will work. First one will be a syntax error at compile time, second one will give PatternSyntaxException at runtime.
Oh I see the issue. Sorry about that. Check again. I have made edits. Use the second method.

String ss="Bebo\'b"; String aa=ss.replaceAll("'\'",""); tv.setText(aa);

This is a delimeter collision problem. You ha ve to do;

Try this:

String result=str.replaceAll("\'\'", "");

Though "\" treated as escape sequence character so it's single "\" is not workable .

Try this..

str.replaceAll("\\","");

Or
