regex compiling in intellij idea but not in android studio and showing

I'm running this code block in java ide i.e. intellij idea it is working fine and also tried some online regex matcher there it also working but when i run this in android studio it is showing error block of code is 

public static String gettime(String temp){

    String result  = new String();

    String time=new String();
    time = ".*([0-1][0-9][:][0-5][0-9][:][0-5][0-9]).*";

    Pattern pattern = Pattern.compile(time);//error during compilation
    Matcher matcher = pattern.matcher(temp);

    if(matcher.matches()){
        result = matcher.group(1);
    }
    return result;
}

and the error is 

java.util.regex.PatternSyntaxException: U_ILLEGAL_ARGUMENT_ERROR
.*([0-1][0-9][:][0-5][0-9][:][0-5][0-9]).*

It works if you switch from [:] to :

time = ".*([0-1][0-9]:[0-5][0-9]:[0-5][0-9]).*";

escaping also works:

time = ".*([0-1][0-9][\\:][0-5][0-9][\\:][0-5][0-9]).*";

not sure why android does not like [:] but it should be the same as :
