GCM不能正常工作

Question

我決定實施Google Cloud Messaging推送通知以通知用戶有關新聞。我認爲這是話題消息。爲了實施我拿了Google GCM sample。我在清單中添加了所有需要的服務，權限和接收者。當我向Google GCM服務器發送發佈請求時，對消息標識的響應是真實的，但設備不會通知。有什麼事？我在Bluestacks測試。

       SharedPreferences sharedPreferences = 
         PreferenceManager.getDefaultSharedPreferences(context); 
       boolean sentToken = sharedPreferences 
         .getBoolean(GcmPreferences.SENT_TOKEN_TO_SERVER, false);

    private static final String TAG = "GCM"; 

    /**

    * the previous token had been compromised. This call is initiated by the

我的PHP POST請求：

<?php 
$postData = array('to' => '/topics/global', 
        'notification' => array(
         'body' => 'GCM Topic Message', 
         'title' => 'Test message')); 

$curl = curl_init('https://gcm-http.googleapis.com/gcm/send'); 

curl_setopt_array($curl, array(CURLOPT_POST => true, 
CURLOPT_RETURNTRANSFER => true, 
CURLOPT_HTTPHEADER => array(
    'Authorization:key=AIzaSyBbUfgnuDyAmO9G8wk6_eqwZFiYX0J0PxI', 
    'Content-Type:application/json' 
), 
CURLOPT_POSTFIELDS => json_encode($postData))); 

$response = curl_exec($curl); 

if($response === false){ 
    die(curl_error($curl)); 
} 

$responseData = json_decode($response, true); 

// Print the date from the response 
print_r($responseData); 
?> 

我測試POST請求。在Bluestacks App Player和真實手機上測試的Android應用程序。

Answer 1

它看起來像你試圖從你的PHP服務器發送通知消息。通知消息允許您在服務器端指定通知的參數，就像您在此處所做的那樣。

Android上的通知消息需要您不包括的圖標字段，請檢查full list of notification message fields以確保您包含所有必需字段的不同平臺。

此外，您正在使用的快速入門通過數據字段處理下游消息。通過通知字段發送的消息由庫處理，因此onMessageReceived永遠不會被調用。您必須通過onMessageReceived的數據字段發送消息才能被調用。例如，在同一個快速入門中考慮GCM Sender。

Answer 2

Convert notification to data . 

$postData = array('to' => '/topics/global', 
        'notification' => array(
         'body' => 'GCM Topic Message', 
         'title' => 'Test message')); 

$postData = array('to' => '/topics/global', 
        'data' => array(
         'body' => 'GCM Topic Message', 
         'title' => 'Test message')); 

Then only onMessagedReceived is called then on this method generate your own notification.Don't forget on creating your own notification icon,title,text are required field
