Question

我在手机上测试GCM。（2.3.6 android）。

清单文件（MainActivity，First和Second活动不执行任何操作，它们用于其他一些测试目的，不会干扰GCM）。

GCMBroadcastReceiver

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // Explicitly specify that GcmIntentService will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}
}

GCMIntentSErvice

public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;

public GcmIntentService() {
    super("GcmIntentService");
}
public static final String TAG = "GCM Demo";

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
        /*
         * Filter messages based on message type. Since it is likely that GCM will be
         * extended in the future with new message types, just ignore any message types you're
         * not interested in, or that you don't recognize.
         */
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            sendNotification("Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server: " + extras.toString());
        // If it's a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            // This loop represents the service doing some work.
            for (int i = 0; i < 5; i++) {
                Log.i(TAG, "Working... " + (i + 1)
                        + "/5 @ " + SystemClock.elapsedRealtime());
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                }
            }
            Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
            // Post notification of received message.
            sendNotification("Received: " + extras.toString());
            Log.i(TAG, "Received: " + extras.toString());
        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) {
    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

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

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

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

现在，我可以在显示

时从服务器发送消息

向网址发送“POST”请求： https://android.googleapis.com/gcm/send回复代码：200 { “multicast_id”：5410443299609525979， “成功”：1， “失败”：0， “canonical_ids”：0 “结果”：[{ “MESSAGE_ID”： “0：1409160055237618％a13ced80f9fd7ecd”}]}

但之后我没有在手机上看到通知。这里发生了什么。可能的原因是什么？

我连接到家里的wifi，我也在我的手机上激活了数据包，所以即使我解开了wifi（不知道为什么会影响反正，但解决方案here suggested）但我仍然我没有收到任何通知。

任何帮助都将受到高度赞赏。

Answer 1

您的接收器中的类别错误（<category android:name="com.google.android.gcm.demo.app" />）。将其更改为com.example.testconnectionapp，假设这是您应用的包名称。

已发送Android GCM服务器但GCM未推送到设备
