Flutter应用程序在原生android后台服务通知中点击后不会出现在前台

Question

我是初学扑动的。我的flutter应用程序在kotlin上有一个原生的android后台服务，在那里我有一个套接字在运行，每当套接字侦听一些东西时，我就会使用notificationcompat.builder生成一个通知。

但当用户点击通知时，我无法将Flutter应用程序带回前台。

我尝试创建一个pendingintent并将其传递给notificationbuilder setContentIntent（）,但在Tap上什么也没有发生。

本机后台服务上的shownotification函数：

fun shownotification (){
   packageNamer = this.getPackageName()
   launchIntent = this.getPackageManager().getLaunchIntentForPackage(packageName)
   var className = launchIntent?.getComponent()!!.className.javaClass
   intent.action = "SELECT_NOTIFICATION"

   intent.setClass(this,className)
   pendingIntent = PendingIntent.getActivity(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT)

    var builder = NotificationCompat.Builder(this, "notifications")
            .setOngoing(true)
            .setContentIntent(pendingIntent)
            .setFullScreenIntent(pendingIntent, true)
            .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
            .setContentTitle("My notification")
            .setContentText("Much longer text that cannot fit one line...")
            .setStyle(NotificationCompat.BigTextStyle()
            .bigText("Much longer text that cannot fit one line..."))
            .setPriority(NotificationCompat.PRIORITY_HIGH)

    manager?.notify(456,builder.build())

}

AndroidManifest.xml文件：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

<!-- io.flutter.app.FlutterApplication is an android.app.Application that
     calls FlutterMain.startInitialization(this); in its onCreate method.
     In most cases you can leave this as-is, but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->

        android:hardwareAccelerated="true"
        android:windowSoftInputMode="adjustResize">
        <!-- This keeps the window background of the activity showing
             until Flutter renders its first frame. It can be removed if
             there is no splash screen (such as the default splash screen
             defined in @style/LaunchTheme). -->
        <meta-data
            android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
            android:value="true" />

        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
        <intent-filter>
            <action android:name="FLUTTER_NOTIFICATION_CLICK" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

您的专家反馈将非常感谢。谢谢

您需要在通知负载中包含click_action:flutter_notification_click作为“自定义数据”键值对。

Bundle bundle = new Bundle();
bundle.putString(Constants.EXAM_ID,String.valueOf(lectureDownloadStatus.getExamId()));

var builder = NotificationCompat.Builder(this, "notifications")
            .setOngoing(true)
            .setContentIntent(pendingIntent)
            .setFullScreenIntent(pendingIntent, true)
            .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
            .setContentTitle("My notification")
            .setContentText("Much longer text that cannot fit one line...")
            .setStyle(NotificationCompat.BigTextStyle()
            .bigText("Much longer text that cannot fit one line..."))
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setExtras(bundle) // Set the bundle
