Android-Firebase Notification在应用程序在后台运行时无法打开目标活动，而在前台运行正常 [英] Android - Firebase Notification not opening targeted activity when app is in background but working properly in foreground

问题描述

我已经尝试了stackoverflow的一些解决方案.但在我的情况下无法正常工作. 下面是我的MyFirebaseMessagingService类，它扩展了FirebaseMessagingService

I have tried some solution from the stackoverflow . But not working properly in my case. Below is my MyFirebaseMessagingService class which extends FirebaseMessagingService

public class MyFirebaseMessagingService   extends FirebaseMessagingService {

    String url , title , body ;

    Map<String,String> data = new HashMap<>();

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {


        title = remoteMessage.getNotification().getTitle();
        body = remoteMessage.getNotification().getBody();

        if(remoteMessage.getData().size()>0){
            Log.d("DATA", remoteMessage.getData().toString());
            try{
                data = remoteMessage.getData();
                url = data.get("url");
            }
            catch (Exception e){
                Log.e("Error", e.toString());
            }

            showNotification(url , title , body);
        }






    }

    private void showNotification(String url, String title, String body) {
        Intent intent = new Intent(this, NotificationViewer.class);
        intent.putExtra("URL",url);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) ;
        notificationBuilder.setContentTitle(title);
        notificationBuilder.setContentText(body);
        notificationBuilder.setAutoCancel(true);
        notificationBuilder.setSmallIcon(R.drawable.logo);
        notificationBuilder.setContentIntent(pendingIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0,notificationBuilder.build());

    }
}

下面是我的AndroidManifest.xml代码.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="dcastalia.com.munshijobsportal">

    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />


    <application
        android:name=".Controller.AppController"
        android:allowBackup="true"
        android:icon="@drawable/logo"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".activity.SplashActivity"
            android:noHistory="true"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>


        <service android:name=".firebase.MyFirebaseInstanceIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
            </intent-filter>
        </service>
        <service android:name=".firebase.MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

        <activity android:name=".activity.NotificationViewer"
            android:exported="true">
        </activity>
    </application>

</manifest>

我已经尝试了一些解决方案，但不适用于我的情况.当应用程序为前台但不能在后台运行时，一切工作正常. 我想在用户单击通知时打开特定的活动名称NotificationViewer.Java活动.但是当我的应用程序在后台运行时，它将继续打开我的启动器活动.

I have tried out some solution but not working in my case. Everything is working fine when app is foreground but not working in background. I want to open a particular activity name NotificationViewer.Java activity when user click on the notification. But when my app is in background it keep opening my Launcher Activity.

推荐答案

您需要在通知请求中的json负载中设置点击动作 'click_action'=>'YourTAG'并在清单活动中应用相同的标签

You need to set click action in your json payload in notification request 'click_action' => 'YourTAG' and apply same tag in your manifest activity

<activity
      android:name=".activity.NotificationViewer">
      <intent-filter>
             <action android:name="YourTAG" />  
             <category android:name="android.intent.category.DEFAULT"/>              
      </intent-filter>
</activity>
