I have to match some string against "Phone_123":"" where any number instead of 123 is acceptable. I am using regex

\\\"Phone_[0-9]+\\\":\\\"\\\"

and it matches the string (in the yellow rectangle)

AS_2.3.3 when I try it in Android Studio 2.3.3. But when I try the same regex against the same string under debug it doesn't match! What is the problem with my regex?

Use `find()` rather than `matches()` when looking for regex matches inside longer strings (`matches()` only returns a match if the whole string matches the pattern). – Wiktor Stribiżew Apr 21 '18 at 20:38
Will try, but initially I have tried `replaceAll` and it doesn't work under debug too... – isabsent Apr 21 '18 at 20:39
And another point: do not use `\\\"`. Use just `\"` because `"` is not a special regex metacharacter, no need to escape it. – Wiktor Stribiżew Apr 21 '18 at 20:40
@Wiktor Stribiżew: You answer is correct, thanks! – isabsent May 31 '18 at 02:55
