Question

我正在使用GCM和Pubnub将推送通知从一个设备发送到另一个设备。我按照这里给出的代码 -

http://www.pubnub.com/blog/sending-receiving-android-push-notifications-with-gcm-google-cloud-messaging/

我正在接收从其他设备发送的数据，并且还能够显示它。但通知（在通知栏中）无效。

收到数据后，Textview会更改为显示数据，但通知栏中没有任何内容。

以下是我的广播接收器和GCM意向服务的代码（我猜这里可能有问题） -

广播接收器

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver
{
  @Override
  public void onReceive(Context context, Intent intent)
  {
    ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());

    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
    Log.i("NIS", "Inside Brocast receiver");
  }
}

服务

public class GcmIntentService extends IntentService {

private static final int NOTIFICATION_ID = 12345;

public GcmIntentService() {
    super("GcmIntentService");
}

@Override
protected void onHandleIntent(Intent intent)
{
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty() && GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType))
    {
        sendNotification("Received: " + extras.toString());
        Log.i("NIS", "Inside handle intent");
    }
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String msg)
{
    NotificationManager mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, ChatsList.class), 0);

    Log.i("NIS", "send notification notification biulder");

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

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
 }
}

Manifest文件中也可能存在问题。这是我的清单文件 -

<?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".ChatsList"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".ChatActivity"
        android:label="@string/title_activity_chat" >
    </activity>
</application>

<receiver
    android:name=".GcmBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND" >
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <category android:name="your.package.name" />
    </intent-filter>
</receiver>

<service android:name=".GcmIntentService" />
<meta-data android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

Activity中的其他代码（在提供的链接中给出），如GCM注册/取消注册等工作正常。请让我知道问题究竟在哪里。谢谢。

Answer 1

我发现了问题。

我错误地声明了＆lt;接收器＆gt;标签外＆lt;申请＆gt;清单中的标签。所以Receiver没有注册。

感谢。
