Question

我正在我的应用程序中实现GCM，我正在成功注册设备ID，但是当我从服务器发送它时，我没有收到任何通知。以下是我的代码的一部分：清单

 <receiver
        android:name=".services.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <category android:name="com.test.gcm"/>
        </intent-filter>
    </receiver>
    <service android:name=".services.GcmIntentService"/>

内部包服务GcmBroadcastReceiver：

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

        startWakefulService(context, (intent.setComponent(component)));
        setResultCode(Activity.RESULT_OK);
    }
}

最后是gcmIntentService

public class GcmIntentService extends IntentService {

    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;

    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()) {
            sendNotification("Notification " + extras.toString());
        }

        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }

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

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

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setContentTitle("Notification")
                        .setContentText(message)
                        .setStyle(new NotificationCompat.BigTextStyle())
                        .setAutoCancel(true);

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

我不知道可能出现什么问题，甚至不知道如何调试它。谢谢你的帮助

当谈到GCM时，服务和接收者名称非常特别。接收者姓名应为

 <receiver
        android:name="com.google.android.gcm.GCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.packagename" />
        </intent-filter>
    </receiver>

和服务应该是

    <service android:name=".GCMIntentService" />

此外，GCMIntentService应与启动器类位于同一个包中。

问题是尝试启动服务的方法：

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

        startWakefulService(context, (intent.setComponent(component)));
        setResultCode(Activity.RESULT_OK);
    }
}

您使用ComponentName初始化context.getPackageName()这是您应用的主要包（com.test.gcm），但您的GcmIntentService类位于不同的包中（{{ 1}}）。

您可以指定正确的包名称：

com.test.gcm.services

或者您可以以不同的方式启动服务：

ComponentName component = new ComponentName(
                    GcmIntentService.class.getPackage ().getName (),
                    GcmIntentService.class.getName());

未收到GCM通知
