Java validate email address

Comment

Use the following code:

public final static boolean isValidEmail(CharSequence target) {
  if (TextUtils.isEmpty(target)) {
    return false;
  } else {
    return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
  }
}

or the one line solution from @AdamvandenHoven:

public final static boolean isValidEmail(CharSequence target) {
  return !TextUtils.isEmpty(target) && android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}
