新しい AUTH XOAUTH2 コマンドを追加した後に Android プロジェクトを実行しようとすると、次のエラーが発生します。
public SMTPTransport connectToSmtp(String host, int port, String userEmail,String oauthToken, boolean debug) throws Exception
{
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.required", "true");
props.put("mail.smtp.sasl.enable", "false");
session = Session.getInstance(props);
session.setDebug(debug);
final URLName unusedUrlName = null;
SMTPTransport transport = new SMTPTransport(session, unusedUrlName);
// If the password is non-null, SMTP tries to do AUTH LOGIN.
final String emptyPassword = null;
transport.connect(host, port, userEmail, emptyPassword);
byte[] response = String.format("user=%s\1auth=Bearer %s\1\1", userEmail,oauthToken).getBytes();
response = BASE64EncoderStream.encode(response);
transport.issueCommand("AUTH XOAUTH2 " + new String(response),235);
return transport;
}
