android - 应用程序在后台时如何处理推送 firebase 通知单击事件？

Question

我是 Android 新手。

当应用程序打开并且通知来自 firebase 并单击通知时，它会打开通知 Activity ，但是当应用程序处于前台/后台并且收到通知并单击通知时，它会自动打开 mainActivity。

我正在将数据从 FirebaseMessagingService.class 广播到主 Activity 。

为什么？

我的代码如下。

主 Activity

   public class MainActivity extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            LocalBroadcastManager.getInstance(this)
                    .registerReceiver(mHandler,new IntentFilter("Pakage_name_FCM-MESSAGE"));
             }

        private BroadcastReceiver mHandler = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String title = intent.getStringExtra("title");
                String message = intent.getStringExtra("message");
                Log.d("MainActivity-title",title);
                Log.d("MainActivity-message",message); 
            }
        };

        @Override
        protected void onPause() {
            super.onPause();
            // Unregister the Broadcast receiver
 LocalBroadcastManager.getInstance(this).unregisterReceiver(mHandler);
        }
    }

FirebaseNotificationIdService.Class

public class FirebaseNotificationIdService extends FirebaseInstanceIdService {

    private static final String REG_TOKEN = "REG_TOKEN";

    @Override   // each time a new created and system call this method
    public void onTokenRefresh() {
        String recent_token= FirebaseInstanceId.getInstance().getToken();
        Log.d(REG_TOKEN,recent_token);
    }
}

FirebaseMessagingService.class

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        Log.d("Remote Form",remoteMessage.getFrom());

        // check if the message contains data...
        if (remoteMessage.getData().size()> 0){
               Log.d("Message Data", "Message Data---"+remoteMessage.getData() );

            String title=remoteMessage.getData().get("title");
            String message=remoteMessage.getData().get("message");

            Intent intent = new Intent("package_name_FCM-MESSAGE");
            intent.putExtra("title",title);
            intent.putExtra("message",message);
            Log.d("INTENT-TITLE",title);
            Log.d("INTENT-MESSAGE",message);
            LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);
            localBroadcastManager.sendBroadcast(intent);
        }

        //check if the message contain notification

        if (remoteMessage.getNotification()!=null){
            Log.d("Message Body","---"+remoteMessage.getNotification().getBody());
            sendNotification(remoteMessage.getNotification().getBody());
        }
    }

    //Display the notification
    private void sendNotification(String body) {
        Intent intent = new Intent(this,NotificationActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(this,0/*Request code*/,intent,PendingIntent.FLAG_ONE_SHOT);
        //Set sound
        Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notifiBuilder = new NotificationCompat.Builder(this);
        notifiBuilder.setSmallIcon(R.mipmap.ic_launcher);
        notifiBuilder.setContentTitle("Aadhaar Update");
        notifiBuilder.setContentText(body);
        notifiBuilder.setAutoCancel(true);
        notifiBuilder.setSound(notificationSound);
        notifiBuilder.setContentIntent(pendingIntent);

        NotificationManager notificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0/*Id of Notification*/,notifiBuilder.build());
    }
}

Minifest.xml

<activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

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

        <activity android:name=".NotificationActivity"></activity>

您应该使用 WakefulBroadcastReceiver 的实现而不是 FirebaseMessagingService

   public class NotificationsReceiver extends WakefulBroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            //process data from intent
            abortBroadcast();
        }
   }

在你的 list 中

    <receiver
            android:name=".fcm.NotificationsReceiver"
            android:exported="true"
            android:permission="com.google.android.c2dm.permission.SEND">
            <intent-filter android:priority="999">
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
    </receiver>
