GCM：广播意图回调：result = CANCELLED forIntent {act = com.google.android.c2dm.intent.RECEIVE

Question

我正在模拟器和某些设备中接收通知，但是一旦该应用被后台杀死，我就不会在许多电话中收到通知。我已经尝试了互联网上的所有答案，但没有一个对我有用。任何答案将不胜感激。

这是我完成的代码。

我的项目清单文件

    <service android:name="esports.gamerji.com.notification_services.MyFirebaseInstanceIDService"
        tools:ignore="InnerclassSeparator"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/notification" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/colorAccent" />

这是我的firebaseMessaging服务代码。

  public class MyFirebaseMessagingService extends FirebaseMessagingService

private NotificationCompat.Builder mBuilder;
private NotificationManager mNotificationManager;
Random random = new Random();

            }
        }
        return;
    }

    if (remoteMessage.getData().size() > 0)

    }
    Intent intent = new Intent("NotificationReceived");
    try

就像你，但是，在相同的情况下（模拟器和应用程序），家庭的成功，公司的失败。因此，我认为这是外部环境设置的问题。我会继续寻找原因。.
