Question

我正在尝试从GCM Intent Service发送短信。这是我正在使用的代码，但它会中断并给我以下异常，你能告诉我我做错了吗。

 @Override
    protected void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that GCM will be
             * extended in the future with new message types, just ignore any message types you're
             * not interested in, or that you don't recognize.
             */
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
               // sendNotification("Send error: " + extras.toString(), null);
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
               // sendNotification("Deleted messages on server: " + extras.toString(), null);
            // If it's a regular GCM message, do some work.
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
                // This loop represents the service doing some work.
                /*for (int i = 0; i < 5; i++) {
                    Log.i(TAG, "Working... " + (i + 1)
                            + "/5 @ " + SystemClock.elapsedRealtime());
                    try {

                mNo =extras.getString("mobileNumber");
                isSent =extras.getString("isSent");
                sendMessage(message,mNo);


            }
        }
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }

例外情况是：.GcmIntentService $ 1 @ 41ed8458最初在这里注册。你是否错过了对unregisterReceiver（）的调用？

Answer 1

您无法在BroadcastReceiver中注册IntentService，IntentService之后onHandleIntent停留，因为您永远不会拨打unregisterReceiver，泄露这个BroadcastReceiver。

可能的解决方案;

静态注册您的应用程序以接收您创建的IntentFilter（在清单中）

从GCM Intent Service发送短信并在通知中显示送达报告。
