Android:推送通知没有声音/振动/灯光

Question

我在收到通知时听不到声音、振动或灯光。有人可以告诉我我缺少什么吗？

还有一些问题:

1.) 我只在应用程序打开时得到指定的图标。当应用程序关闭时，我会看到 android Logo 图标(我想那是因为我还没有定义应用程序图标)。

2.) 代码文本仅在应用程序打开时显示。

3.) 当应用程序打开时，我没有得到内容文本，只有内容标题。

解决方案:发生这种情况是因为我在以前的版本上使用 com.google.android.gms:play-services-gcm:8.4.0。

确保在服务器上发送的通知数组仅包含键/值对 e=0，同时在数据数组中发送消息信息。

这个问题在这里已经有了很好的答案:After updating Google play services to 8.4.0 push notifications displayed by themselves

这是我的来源:

public class MyGcmListenerService extends GcmListenerService {

    private final static String TAG = "GCM_Listener";

    @Override
    public void onMessageReceived(String from, Bundle data) {
        String message = data.getString("message");
        Log.d(TAG, "From: " + from + " (" + message);

        // Sets an ID for the notification
        SharedPreferences sharedPreferences = getSharedPreferences(getString(R.string.sharedPreferenceStore_default), Context.MODE_PRIVATE);

        int mNotificationId = sharedPreferences.getInt("id_notification", 0);
        mNotificationId++;

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.all_picks_made_indicator)
                        .setAutoCancel(true)
                        .setContentTitle("Product - " + mNotificationId)
                        .setContentText(message)
                        .setTicker("Product Notification received");



        // Because clicking the notification opens a new ("special") activity, there's no need to create an artificial back stack.
        PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, DetectLoginActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);

        // Gets an instance of the NotificationManager service
        NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        // Builds the notification and issues it.
        Notification notification = mBuilder.build();
        notification.defaults = Notification.DEFAULT_ALL;
        mNotifyMgr.notify(mNotificationId, notification);

        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putInt("id_notification", mNotificationId);
        editor.commit();
    }
}

推送通知的自定义声音

notification.sound = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.pop);

在你的代码更改中

    Notification notification = mBuilder.build();
    notification.defaults = Notification.DEFAULT_ALL;
    mNotifyMgr.notify(mNotificationId, notification);

到。

notification.sound = Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.pop);
notification.defaults |= Notification.DEFAULT_VIBRATE;
