Question

我想要的内容：我想向用户发送推送通知。当用户点击该通知时，用户应导航至特定活动。

我的工作：我在Firebase控制台中创建了一个深层链接。我还实现了 FirebaseInstanceIdService 和 FirebaseMessagingService 。我能够捕获从Firebase控制台发送的Firebase消息。

问题是什么：我无法捕获在Firebase控制台中创建的动态链接。

我的代码如下。

MyFirebaseInstanceIDService.java

    public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private final String TAG = "MyFirebaseInstanceID";

    @Override
    public void onTokenRefresh() {

        String refreshedToken = FirebaseInstanceId.getInstance().getToken();

        Log.e(TAG, "Refreshed token: " + refreshedToken);
    }
}

MyFirebaseMessagingService.java

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private final String TAG = "MyFbaseMessagingService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        String message = remoteMessage.getNotification().getBody();

        Log.e(TAG, "\nmessage: " + message);

        sendNotification(message);
    }

    private void sendNotification(String message) {

        Intent intent = new Intent(this, TestDeepLinkActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setAutoCancel(true)
                .setContentTitle("FCM Test")
                .setContentText(message)
                .setSound(defaultSoundUri)
                .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
                .setContentIntent(pendingIntent);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        manager.notify(0, builder.build());
    }
}

解决方案：

我必须在要推送的通知清单中的清单文件中的活动中添加意图过滤器。该通知将包含一些在Android术语中称为Deeplink的网址。您可以在下面的链接中获得有关Deeplink的更多信息。

https://developer.android.com/training/app-links/deep-linking

我将这两个链接用作深层链接：“ www.somedomain.com/about”和“ www.somedomain.com/app”。
请不要在意图过滤器中添加 http 或 https ，这是不受支持的。 Chekout this对话中有更多说明。我还要添加该聊天的图像，以防万一将来链接失效。

请参阅以下代码，以了解如何将深度链接传递给NotificationManager。意向过滤器自动拦截并启动该特定活动。

MyFirebaseMessagingService.java

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        Map<String, String> data = remoteMessage.getData();

        String title = data.get("title");
        String message = data.get("message");
        String deepLink = data.get("deepLink");

        Notification notification = new Notification();
        notification.setTitle(title);
        notification.setMessage(message);
        notification.setDeepLink(deepLink);

        sendNotification(this, title, message, deepLink);
    }

    public static void sendNotification(Context context, String title, String message, String deepLink) {

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= 26) {
            NotificationChannel notificationChannel = new NotificationChannel("any_default_id", "any_channel_name",
                    NotificationManager.IMPORTANCE_HIGH);
            notificationChannel.setDescription("Any description can be given!");
            notificationManager.createNotificationChannel(notificationChannel);
        }

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setPriority(android.app.Notification.PRIORITY_MAX)
                .setDefaults(android.app.Notification.DEFAULT_ALL)
                .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));

        Intent intent = new Intent();

        intent.setAction(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(deepLink));
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);

        notificationBuilder
                    .setContentTitle(title)
                    .setContentText(message)
                    .setContentIntent(pendingIntent);

        notificationManager.notify(0, notificationBuilder.build());
    }
}

AndroidManifest.xml

        <activity
        android:name=".mvp.view.activity.ActivityName"
        android:label="@string/title_activity_name"
        android:theme="@style/AppTheme.NoActionBar">

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="www.somedomain.com"
                android:path="/about"
                android:scheme="app" />
        </intent-filter>

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="www.somedomain.com"
                android:path="/contact"
                android:scheme="app" />
        </intent-filter>
    </activity>

其他：

如果您想在该活动中接收更多数据（即userId或loanId），则可以在从服务器（即后端或基于Web的仪表板）发送推送通知时将其传递给。您可以像下面这样。
```
{
 "data": {
 "userId": "65431214564651251456",
 "deepLink": "www.somedomain.com/app",
 "title": "This is title!",
 "message": "This is message!"
 },
"to": "FCM token here"
}
```

重要提示：JSON以下将不起作用，仅供参考。文档中也没有提到这一点。因此，请照顾好它。正确的JSON在上方。

{
  "to": "FCM Token here",
   "notification": {
   "Body": "This week’s edition is now available.",
    "title": "NewsMagazine.com",
    "icon": "new"
     },
  "data": {
  "title": "This is title!",
  "message": "This is message!"
  }
}

您可以在如下所示的 MyFirebaseMessagingService 类的 onMessageReceived 方法中接收额外的数据（即userId或loanId）。
```
String userId = data.get("userId");
intent.putExtra(Intent.EXTRA_TEXT, userId);
```

在该活动中，您可以像下面的onCreate方法中那样编写。

Intent intent = getIntent();
if (intent != null) {
String intentStringExtra = intent.getStringExtra(Intent.EXTRA_TEXT);
if (intentStringExtra != null) {
    userId = intentStringExtra;
   }
}
