推送通知接收器不工作

Posted 2023-02-24

【中文标题】推送通知接收器不工作

【英文标题】：Push Notification receiver is not working

【发布时间】：2013-07-12 23:36:54

【问题描述】：

我正在我的应用程序中实现推送通知服务，我按照教程on android developers.com，但不幸的是，我没有收到任何通知。

我成功接收到注册id，但是设备没有收到后端的任何通知，虽然后端服务收到了成功的响应。

p.s ：我确信从将通知发送到 Google 云服务器的后端服务的实现。

谁能帮我解决这个问题..？提前谢谢。

您可以在下面找到我的实现。

- 我在主活动中的注册码：

    new AsyncTask<CallbackContext, Void, String>() 
        CallbackContext context;

        @Override
        protected String doInBackground(CallbackContext... params) 
            // TODO Auto-generated method stub
            context = params[0];
            String regid = "";
            try 
                if (gcm == null) 
                    gcm = GoogleCloudMessaging.getInstance(cordova
                            .getActivity());
                
                regid = gcm.register(Constants.SENDER_ID);

             catch (IOException ex) 
                Log.d("Exceptio:", ex.getMessage());
            
            String message = "\"ChannelURI\":\"" + regid + "\"";
            return message;

        ;

        protected void onPostExecute(String result) 
            try 
                JSONObject jResult = new JSONObject(result);

                context.success(jResult);
             catch (JSONException e) 
                // TODO Auto-generated catch block
                e.printStackTrace();
            

        
    .execute(ctx);

【问题讨论】：

您在尝试处理推送通知之前是否运行过活动？

是的，我在从后端发送通知之前运行应用程序。

能否在 GCMIntentService 中的 onRegistered 和 onUnregistered 方法中添加日志消息，以了解应用是否连接成功？

两个都进不了，什么时候进..？

那么它一开始就没有注册。您可以显示您注册推送通知的代码吗？特别是你打电话给GoogleCloudMessaging.getInstance(context).register(SENDER_ID);

【参考方案1】：

您的清单中存在包名称不匹配的问题：

应用程序包：

package="com.ettamen.app"

在权限中，您应该使用应用程序的包，但您使用的是：

<permission
        android:name="com.ettamen.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.ettamen.permission.C2D_MESSAGE" />

两者都应该是com.ettamen.app.permission.C2D_MESSAGE。

最后是广播接收器：

<receiver
    android:name="com.ettamen.app.pushnotifications.CordovaGCMBroadcastReceiver"
    android:exported="true"
    android:permission="com.google.android.c2dm.permission.SEND" >
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />

        <category android:name="com.ettamen.app.pushnotifications" />
    </intent-filter>
</receiver>

类别应包含您的应用程序包名称，因此应为com.ettamen.app。

【讨论】：

感谢通知，但是仍然没有进入onRegistered和onUnregistered方法，也没有收到推送通知。

@EslamYousefMohammed 现在我查看了您的代码，我发现它是旧 API 和新 API 的混合体。如果您使用 GCMRegistrar，请不要使用 GoogleCloudMessaging，反之亦然。如果您在后台线程中调用gcm.register，这就足够了，您不必调用GCMRegistrar.register。使用 GoogleCloudMessaging.register 时，永远不会调用 onRegistered 和 onUnregistered。

我编辑了我的注册方法，并将我的接收器更新为与developers.android.com教程完全匹配。“帖子也更新了”。现在，我成功收到了注册ID，但是，设备没有收到来自后端的任何通知，尽管后端服务收到了成功的响应。

@EslamYousefMohammed 那是因为你忘了把<category android:name="com.ettamen.app.pushnotifications" />改成<category android:name="com.ettamen.app" />。

@Eran，您在 GCM 上的回答对我有很大帮助。但是我卡住了，你能看一下吗？ my gcm question

【参考方案2】：

经过大量试验，我发现问题是接收器可以在您喜欢的任何包中，只要清单中其意图过滤器的类别包含应用程序的主包

感谢大家的帮助和支持。

【参考方案3】：

当您使用 builder 构建通知时，您应该在此处设置传递给 onReceive 方法的意图，而不是您创建的方法：

mBuilder.setContentIntent(contentIntent);

完整代码：

import com.ettamen.app.R;

import com.google.android.gms.gcm.GoogleCloudMessaging;

/*
 * Implementation of GCMBroadcastReceiver that hard-wires the intent service to be 
 * com.plugin.gcm.GCMIntentService, instead of your_package.GCMIntentService 
 */
public class CordovaGCMBroadcastReceiver extends BroadcastReceiver 

static final String TAG = "GCMDemo";
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
Context ctx;

@Override
public void onReceive(Context context, Intent intent) 
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
        ctx = context;
        String messageType = gcm.getMessageType(intent);
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) 
            sendNotification("Send error: " + intent.getExtras().toString(), intent);
         else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                .equals(messageType)) 
            sendNotification("Deleted messages on server: "
                    + intent.getExtras().toString(), intent);
         else 
            sendNotification("Received: " + intent.getExtras().toString(), intent);
        
        setResultCode(Activity.RESULT_OK);
    

    // Put the GCM message into a notification and post it.
    private void sendNotification(String msg, Intent intent) 
        mNotificationManager = (NotificationManager) ctx
                .getSystemService(Context.NOTIFICATION_SERVICE);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                ctx).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("GCM Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg);

        mBuilder.setContentIntent(intent); // here passing the valid intent
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    

也可以应用于GCMIntentService类。
