【问题描述】:
收到通知时,我没有听到声音、振动或灯光。有人可以告诉我我缺少什么吗?
我还有一些其他问题:
1.) 我只在应用打开时获得指定的图标。当应用程序关闭时,我会看到 android 徽标图标(我猜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了com.google.android.gms:play-services-gcm:8.4.0。
确保在服务器上发送一个仅包含键/值对 e=0 的通知数组,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();
}
}
