次のコードを使用して、Android アプリケーションでメールを送信しています。
m_properties = new Properties();
m_properties.put("mail.smtp.host", "smtp.gmail.com");
m_properties.put("mail.smtp.socketFactory.port", "465");
m_properties.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
m_properties.put("mail.smtp.auth", "true");
m_properties.put("mail.smtp.port", "465");
m_Session = Session.getDefaultInstance(m_properties,
new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName,
passWord);
}
});
m_simpleMessage = new MimeMessage(m_Session);
m_fromAddress = new InternetAddress(userName);
m_toAddress = new InternetAddress(eRecipient);
m_simpleMessage.setFrom(m_fromAddress);
m_simpleMessage.setRecipient(RecipientType.TO, m_toAddress);
m_simpleMessage.setSubject(eSubject);
m_simpleMessage.setContent(eBody, "text/plain");
Transport.send(m_simpleMessage);
コードを難読化するまでは、問題なく動作します。その後、電子メールの送信に失敗し、次のエラーがスローされます: javax.mail.nosuchproviderexception smtp
proguard.cfg で次のようなさまざまな設定を試みました。}
しかし、何も機能しません。難読化をオフにすると、再び正常に動作します。
なぜこれが起こるのでしょうか?
前もって感謝します。
