我一直在尝试使用Android中的JavaMail API删除电子邮件。我已经能够在我的应用程序中获取和查看电子邮件。虽然无法删除任何电子邮件，但没有错误或任何可能导致解决方案的警告。这是我到目前为止所尝试的。非常感谢帮助。

import android.content.Intent;

import com.emazdoor.encmail.customlistview.MainList;
import com.sun.mail.imap.IMAPFolder;
public class DeleteEmail {
static Message[] messages;
public static void delete(final int number)
{
new AsyncTask<Void, Void, Void>() {
@Override
public Void doInBackground(Void... voids) {
try {
int num = number;
Store store = null;
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
Session session = Session.getDefaultInstance(props, null);
store = session.getStore("imaps");
store.connect("imap.googlemail.com", dumber.username,
dumber.password);
// create the folder object and open it
IMAPFolder emailFolder = (IMAPFolder) store.getFolder("INBOX");
emailFolder.open(Folder.READ_WRITE);
// retrieve the messages from the folder in an array and
// print it
messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0; i < 5; i++) {
Message message = messages[i];
}
if (messages != null && messages.length > 0)
messages[817].setFlag(Flags.Flag.DELETED, true);
// expunges the folder to remove messages which are marked
// deleted
emailFolder.close(true);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
return null;
}
}.execute();
}
}
我做错了吗？
我会在messages[variable].setFlag(Flags.Flag.DELETED, true);中使用变量而不是硬编码值。
更新
我设置setDebug(true)这就是我得到的......似乎一切都好......
