Мое приложение в настоящее время отправляет электронные письма через обычный SMTP-доступ, и оно отлично работает на устройствах SDK 19+, но у меня возникают проблемы в моем Asus Android 4.3 SDK 18 с ошибкой, описанной в заголовке.
Странно дело в том, что я использую не StandardCharsets.UTF_8, а буквальный "UTF-8" и не имеет значения
Я не планирую использовать go в Gmail API, так как я не в настроении "борьбы" с использованием аутентификации oAuth, поэтому я пытаюсь найти простое исправление для того, что у меня уже есть.
Ниже приведен код, который я использую, и не имеет значения, использую ли я "UTF -8 "параметр или нет. Всегда одна и та же ошибка в строке Transport.Send.
Есть идеи, чтобы заставить его работать в SDK 18-устройствах, ребята?
public static String send(String jsonEmail)
{
String result = Enum.Result.OK;
AppSettings appSettings = AppSettings.getInstance();

String message = oJsonEmail.getString("message");
String sendTo = oJsonEmail.getString("send_to");
String smtpServer = oJsonEmail.getString("smtp_server");
String smtpPort = oJsonEmail.getString("smtp_port");
String smtpUseAuth = oJsonEmail.getString("smtp_useauth");
boolean centerBodyText = Boolean.parseBoolean(oJsonEmail.getString("center_text"));
final String smtpUser = oJsonEmail.getString("smtp_user");
final String smtpPass = oJsonEmail.getString("smtp_pass");

Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(smtpUser, smtpPass);
}
});

oMessage.setRecipients(Message.RecipientType.TO, InternetAddress.parse(sendTo));
oMessage.setSubject(subject);
oMessage.setContent(message, "text/html; charset=iso-8859-2");
Transport.send(oMessage);
}catch (MessagingException | UnsupportedEncodingException | JSONException e) {
