title: How should I validate an e-mail address?
body: <p>What's a good technique for validating an e-mail address (e.g. from a user input field) in Android? <a href="http://commons.apache.org/validator/apidocs/org/apache/commons/validator/routines/EmailValidator.html" rel="noreferrer">org.apache.commons.validator.routines.EmailValidator</a> doesn't seem to be available. Are there any other libraries doing this which are included in Android already or would I have to use RegExp?</p>
