Don't use regex to validate phone numbers either (and probably not even emails) unless you have very specific rules for the emails/phones you will accept — Explosion Pills

Since API Level 8 and above, Android has patterns for email, phone number e etc; that you can use. For example:

private boolean isValidEmail(CharSequence email) {
    if (!TextUtils.isEmpty(email)) {
        return Patterns.EMAIL_ADDRESS.matcher(email).matches();
    }
    return false;
}

private boolean isValidPhoneNumber(CharSequence phoneNumber) {
    if (!TextUtils.isEmpty(phoneNumber)) {
        return Patterns.PHONE.matcher(phoneNumber).matches();
    }
    return false;
}

For more details, see: http://developer.android.com/reference/android/util/Patterns.html

Hope this helps.
