see the code you are using `else if(Mail.matches(emailPattern)` you should use **`else if(!Mail.matches(emailPattern)`** you forgot the `!` sign i think. — SMR, Jan 31 '14 at 13:47

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

If email Address is Valid Then it will Return True other Wise false

The easiest method will be to use the inbuilt methods:

if(!android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches())
{
    mail.setError("Enter valid Address");
}

or you can do email validation using a regular expressions like this:

private static final String EMAIL_REGEX = "^[_a-z0-9-\\+]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

and validate it like this

......
else if (!Mail.matches(EMAIL_REGEX)) 
{
    mail.setError("Enter valid Address");
}
....

or you can also try the inbuilt matcher:

[EDIT]: changed REGEX to avoid CAP chars.

[NOTE]: make sure you have ! sign inside if otherwise you will suffer reverse effect.

Hope it helps. :)

Always start variable names with a lowercase letter.

If you need to check if a string is empty use either string.isEmpty() or string.length() == 0. If the string can be null, use TextUtils.isEmpty(string). String.compareTo("") == 0 is very bad.

And finally, for checking email validity use Patterns.EMAIL_ADDRESS.matcher(emailString).matches()
