Why is my regex not parsed correctly on sms receiver in android?

In my android application I am parsing sms received through broadcast.

I put my regex in string.xml

<string name="message_verification_regex">^.*Your Verification Code is \\d{4}.*$</string>

And message I am trying to parse is 

1234567890:
Your Verification Code is 5840.

You can try to add (?m) at the start of your regex. That way, ^ will match the start of any line (instead of the start of your string, i.e. start of the 1st line only):

<string name="message_verification_regex">(?m)^.*Your Verification Code is \\d{4}.*$</string>

The string is a multiline string, but the dot does not match newline characters. Use

<string name="message_verification_regex">^[\\s\\S]*?Your Verification Code is \\d{4}[\\s\\S]*$</string>

The expression [\s\S] matches any whitespace character and any non-whitespace character which means really any character.

I must add that I don't know if escaping a backslash with an additional backslash is really necessary where the string with this regular expression is used. Therefore try also:

<string name="message_verification_regex">^[\s\S]*?Your Verification Code is \d{4}[\s\S]*$</string>
