Validate mobile number using regular expressions in android

Hi guys Here I am going to explain how to validate  Mobile number using Regular Expressions

MobileNo = mobileid.getstring();

if(Helper.isValidMobile(MobileNo)){

    Toast.makeText(activity, "Valid", Toast.LENGTH_SHORT).show();
} else {

Toast.makeText(activity, "Not Valid", Toast.LENGTH_SHORT).show();
}

public static boolean isValidMobile(String argEditText) {
    try {
        Pattern pattern = Pattern.compile("^[+]?[0-9]{10,13}$");
        Matcher matcher = pattern.matcher(argEditText);
        return matcher.matches();
    } catch (Exception e) {
        if (ConfVars.PRINTEXECEPTOION) {
            e.printStackTrace();
        }
        return false;
    }
}
