GCM不起作用

我决定实施Google Cloud Messaging推送通知，以通知用户有关新闻的信息。我认为这是主题消息。为了实现，我采用了Google GCM sample。我在清单中添加了所有需要的服务，权限和接收器。当我向Google GCM服务器发送帖子请求时，响应为true，但是设备没有通知。有什么事？我在Bluestacks测试过。

我的清单：

主要活动：

public class MainActivity extends AppCompatActivity {    

    private BroadcastReceiver mRegistrationBroadcastReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRegistrationBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                SharedPreferences sharedPreferences =
                        PreferenceManager.getDefaultSharedPreferences(context);
                boolean sentToken = sharedPreferences
                        .getBoolean(GcmPreferences.SENT_TOKEN_TO_SERVER, false);
                if (sentToken) {
                    Log.i("GCM", "Success!");
                } else {
                    Log.i("GCM", "Error!");
                }
            }
        };

        Intent intent = new Intent(this, RegistrationIntentService.class);
        startService(intent);
    }
}

GCM侦听器服务：

public class AppGcmListenerService extends GcmListenerService {

    private static final String TAG = "GCM";

    /**
     * Called when message is received.
     *
     * @param from SenderID of the sender.
     * @param data Data bundle containing message data as key/value pairs.

     */

         * that a message was received.
         */
        sendNotification(message);
    }

    /**
     * Create and show a simple notification containing the received GCM message.
     *
     * @param message GCM message received.
     */
    private void sendNotification(String message) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_app)
                .setContentTitle("GCM Message")
                .setContentText(message)

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }
}

实例ID侦听器服务：

public class AppInstanceIDListenerService extends InstanceIDListenerService {

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. This call is initiated by the
     * InstanceID provider.
     */

    public void onTokenRefresh() {
        // Fetch updated Instance ID token and notify our app's server of any changes (if applicable).
        Intent intent = new Intent(this, RegistrationIntentService.class);
        startService(intent);
    }
}

注册意向服务：

public class RegistrationIntentService extends IntentService {

private static final String TAG = "GCM";

public RegistrationIntentService() {
    super(TAG);
}

@Override
protected void onHandleIntent(Intent intent) {
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

    try {
        // In the (unlikely) event that multiple refresh operations occur simultaneously,
        // ensure that they are processed sequentially.
        synchronized (TAG) {
            // Initially this call goes out to the network to retrieve the token, subsequent calls
            // are local.
            InstanceID instanceID = InstanceID.getInstance(this);
            String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
                    GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

            Log.d(TAG, "GCM Registration Token: " + token);

            subscribeTopics(token);

            // You should store a boolean that indicates whether the generated token has been
            // sent to your server. If the boolean is false, send the token to your server,
            // otherwise your server should have already received the token.
            sharedPreferences.edit().putBoolean(GcmPreferences.SENT_TOKEN_TO_SERVER, true).apply();
        }
    } catch (Exception e) {
        Log.d(TAG, "Failed to complete token refresh", e);
        // If an exception happens while fetching the new token or updating our registration data
        // on a third-party server, this ensures that we'll attempt the update at a later time.
        sharedPreferences.edit().putBoolean(GcmPreferences.SENT_TOKEN_TO_SERVER, false).apply();
    }
    // Notify UI that registration has completed, so the progress indicator can be hidden.
    Intent registrationComplete = new Intent(GcmPreferences.REGISTRATION_COMPLETE);
    LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}

/**
 * Subscribe to any GCM topics of interest, as defined by the TOPICS constant.
 *
 * @param token GCM token
 * @throws IOException if unable to reach the GCM PubSub service
 */
private void subscribeTopics(String token) throws IOException {
    GcmPubSub.getInstance(this).subscribe(token, "/topics/global", null);
}

}

我的PHP POST请求：

<?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);
?>

我测试了POST请求。在Bluestacks App Player和真实手机上测试了Android应用。

看起来您正在尝试从PHP服务器发送通知消息。通知消息允许您在服务器端指定通知的参数，就像您在此处一样。

Android上的通知消息需要您不包含的图标字段，请检查full list of notification message fields以确保包含所有必要字段的不同平台。

您正在使用的快速入门通过数据字段处理下游消息。通过通知字段发送的消息由库处理，因此永远不会调用onMessageReceived。您必须通过数据字段发送消息，以便调用onMessageReceived。在一个示例的同一快速入门中考虑GCM Sender。

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
