You can try the following code:

private List getResult1(){
  try {
    Properties props = new Properties();
    props.put("mail.store.protocol","imaps");
    Session session = Session.getDefaultInstance(props, null);
    Store store = session.getStore("imaps");
    store.connect("imap.gmail.com", "Email Id", "App Password");

    //if you want mail from specified folder, just change change folder name
    //Folder inbox = store.getFolder("[Gmail]/Drafts");
    Folder inbox = store.getFolder("inbox");

    inbox.open(Folder.READ_ONLY);
    int messageCount = inbox.getMessageCount();
    Log.e("getFolder ", "getResult1: " + store.getDefaultFolder().list("*"));
    javax.mail.Folder[] folders = store.getDefaultFolder().list("*");

    for (javax.mail.Folder folder : folders) {
      if ((folder.getType() & javax.mail.Folder.HOLDS_MESSAGES) != 0){
        Log.e("getFolder ", "getResult1: " + folder.getName() );
      }
    }

    Log.e("Mail Subject:", "Total Messages:-: " + messageCount );
    javax.mail.Message[] messages = inbox.getMessages();

    System.out.println("------------------------------");
    Log.e("Mail Subject:", "messages: " + messages.toString());
    for (int i = 0; i < messages.length; i++) {
      Log.e("Mail Subject:", "getResult1: " + messages[i].getSubject());
    }
    inbox.close(true);
    store.close();
  } catch (Exception e) {
    e.printStackTrace();
  }
  return null;
}
