SmsManager sendTextMessage不工作

Question

SmsManager sendTextMessage在某些条件下不工作.

我创建了一个使用SmsManager发送消息的android应用程序，它在模拟器和实际设备上一直运行良好。然而，最近我几乎没有收到用户的抱怨，说我的应用程序无法在他们的设备上发送短信。我很确定所有的权限都被授予了，并且在Crashlytics报告中没有崩溃和错误。

我试着在Android模拟器上模拟这个问题，我意识到，当我将蜂窝网络类型更改为"GSM“并将其更改回”完全“时，可能会导致SmsManager sendTextMessage无法工作。我还添加、发送和交付了挂起的意图，但没有一个返回错误代码给我。调用sendTextMessage方法后完全没有响应。

如果您对此有任何解决方案，请帮助。

备注：

1. 非常确定所有的权限都被授予(READ_SMS，RECEIVE_SMS，SEND_SMS，READ_PHONE_STATE.)
2. 调用sendTextMessage方法后，没有挂起意图造成的崩溃和错误代码。
3. 消息小于10个字符。

public void sendSMS(String phoneNumber, String message) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(getContext(), 0, new Intent(
            SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(getContext(), 0, new Intent(
            DELIVERED), 0);

    BroadcastReceiver sendSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Broadcast_SMSReceiver.mSMSReceiver.receivedSMS(true);
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getContext(), "Generic failure",
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:

                case SmsManager.RESULT_ERROR_SHORT_CODE_NOT_ALLOWED:
                    Toast.makeText(getContext(), "Premium short codes denied",
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_SHORT_CODE_NEVER_ALLOWED:
                    Toast.makeText(getContext(), "Premium short codes denied",
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_LIMIT_EXCEEDED:
                    Toast.makeText(getContext(), "Reached the sending queue limit",
                            Toast.LENGTH_SHORT).show();
                    break;
                default:
                    Toast.makeText(getContext(), getResultCode(),
                            Toast.LENGTH_SHORT).show();
            }
        }
    };


    BroadcastReceiver deliverSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getContext(), "SMS delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getContext(), "SMS not delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    };

    getActivity().registerReceiver(sendSMS, new IntentFilter(SENT));
    getActivity().registerReceiver(deliverSMS, new IntentFilter(DELIVERED));
    try {
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, "test", sentPI, deliveredPI);
    }catch (Exception e){
        Toast.makeText(getContext(),
                "SMS failed, please try again later ! ",
                Toast.LENGTH_LONG).show();
        e.printStackTrace();

    }

    Broadcast_SMSReceiver.mSMSReceiver.receivedSMS(true);
}

我认为您的问题可能是用户想要发送的信息超过160个字符。

看起来，如果您使用超过允许长度的消息调用SmsManager::sendTextMessage(...)，则调用将悄然失败。不会引发任何异常，sentPI意图也不会被执行。
