Question

我希望在使用c＃输入数据db时发送通知。我已经做了一些事情，但我不知道我的代码中我做错了什么，问题是

当我运行模拟器推送通知工作正常但我跑的时候在真实设备上我没有得到推送通知。

请帮帮我。提前谢谢。

这是我的 manifest ，

<?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.studentcares.spps">
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:largeHeap="true"
    android:theme="@style/AppTheme">
    <receiver android:name="com.studentcares.spps.otpReader.SmsReceiver">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>
    <service           
   android:name="com.studentcares.spps.firebase.MyFirebaseMesagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>

    <service android:name="com.studentcares.spps.firebase.MyFirebaseInstanceIdService">

        </intent-filter>
    </service>

    <activity android:name="com.studentcares.spps.MainActivity"/>

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
</application>

</manifest>

这是 firebaseMessaging 服务代码，

public class MyFirebaseMesagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    showNotification(remoteMessage);
    //showNotification(remoteMessage.getData().get("message"));
}
private void showNotification(RemoteMessage remoteMessage){
    Intent intent = new Intent(this, MainActivity.class);
    //intent.putExtra("Message", remoteMessage.getNotification().getBody());
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
    notificationBuilder.setAutoCancel(true);
    notificationBuilder.setContentTitle("FCM Notification");
    notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
    notificationBuilder.setSmallIcon(R.drawable.ic_launcher_short);
    notificationBuilder.setLargeIcon(BitmapFactory.decodeResource(this.getResources(),R.drawable.ic_launcher));
    notificationBuilder.setPriority(2);
    notificationBuilder.setContentIntent(pendingIntent) ;
    NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0,notificationBuilder.build());
}
}

这是我的c＃代码，

try
    {

        string applicationID = "server api key";

        string senderId = "sender id";

        string deviceId = "registration fcm id";

        WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
        tRequest.Method = "post";
        tRequest.ContentType = "application/json";
        var data = new
        {
            to = deviceId,
            notification = new
            {
                body = "test",
                title = "Push Notification",
                sound = "Enabled"

            }
        };
        var serializer = new JavaScriptSerializer();
        var json = serializer.Serialize(data);
        Byte[] byteArray = Encoding.UTF8.GetBytes(json);
        tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
        tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
        tRequest.ContentLength = byteArray.Length;
        using (Stream dataStream = tRequest.GetRequestStream())
        {
            dataStream.Write(byteArray, 0, byteArray.Length);
            using (WebResponse tResponse = tRequest.GetResponse())
            {
                using (Stream dataStreamResponse = tResponse.GetResponseStream())
                {
                    using (StreamReader tReader = new StreamReader(dataStreamResponse))
                    {
                        String sResponseFromServer = tReader.ReadToEnd();
                        string str = sResponseFromServer;
                    }
                }
            }
        }
    }

每当遇到此问题时，只需重新启动设备即可正常运行。

C＃推送通知在仿真器上工作但不在真实设备上工作
