String.replaceAll without RegEx
Just use String.replace(CharSequence,CharSequence) rather than replaceAll.
NB: replace doesn't just replace the first occurrence, it replaces all occurrences, like replaceAll.
The method to add escapes is Pattern.quote().
String replaced = myString.replaceAll(Pattern.quote(matchingStr), replacementStr)
But as Jon says you can just use replace(). Despite the fact that it deviates from the replaceAll name, it does replace all occurrences just like replaceAll().
