SmsManager发送某些消息失败

Question

我已经实现了发送长度为500个字符的消息，所以分为160个字符的消息。

但由于它跳过了一些消息，所以我添加了异步任务，但问题仍然是连续的，可以帮助我解决

这是我的代码，

public class SendMessage
    {

        public static void SendSMS(Activity activity, String Msg)
        {

            try {
                 SmsSendTask mAuthTask=null;
                 mAuthTask = new SmsSendTask(Msg);
                 mAuthTask.execute((Void) null);
            } catch (Exception e) {
                Toast.makeText(activity, "SMS failed, please try again.", Toast.LENGTH_LONG).show();
                System.out.println(e.toString()+"<<e>>>");
                e.printStackTrace();
            }
        }


        public static class SmsSendTask extends AsyncTask<Void, Void, Boolean> {
            private final String _msg;
                SmsSendTask(String msg) {
                _msg = msg;
        }

            @Override
            protected Boolean doInBackground(Void... params) {
                 try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    return false;
                }
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage("9246591931", null, _msg, null, null);
                return true;
            }

            @Override
            protected void onPostExecute(final Boolean success) {
                if (success) {
                } else {
                }
            }

            @Override
            protected void onCancelled() {
            }
        }
    }

    String body="this is my message";
    SmsManager sms = SmsManager.getDefault();
    ArrayList<String>arraylist = new ArrayList<String>();
    arraylist=sms.divideMessage(body);
    try
    {
        sms.sendMultipartTextMessage(address, null,arraylist, null,null);

    }
    catch (Exception e)
    {

    }
