具有推送通知的深度 Link - FCM - Android

Question

我想要什么：我想向用户发送推送通知。当用户点击该通知时，用户应导航至特定的 activity.

我做了什么： 我在 Firebase 控制台中创建了一个深度 link。我也实施了 FirebaseInstanceIdService & FirebaseMessagingService。我能够捕获从 Firebase 控制台发送的 Firebase 消息。

问题是什么： 我无法捕获我在 Firebase 控制台中创建的动态 link。

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());
    }
}

解法：

我必须在清单文件中的 activity 中添加 intent-filter，我想点击推送通知。此通知将包含一些 url，在 Android 术语中称为 deeplink。你可以参考下面link了解更多关于deeplink.

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

我用这两个 link 作为深度 link："www.somedomain.com/about" & "www.somedomain.com/app".
请不要在 intent-filter 中添加 http 或 https，它们不受支持。 Chekout this 对话以获得更多说明。我也放了那个聊天的图片，如果将来 link 过期了。

请参考下面的代码，了解我如何将 deeplink 传递给 NotificationManager。 intent-filter 自动拦截并启动特定的 activity.

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>

额外:

如果您想在 activity 中接收更多数据（即 userId 或 loanId），您可以在从您的服务器（即后端或基于 Web 的仪表板）。你可以像下面那样做。
```
{
 "data": {
 "userId": "65431214564651251456",
 "deepLink": "www.somedomain.com/app",
 "title": "This is title!",
 "message": "This is message!"
 },
"to": "FCM token here"
}
```
重要提示：低于JSON无效，仅供参考。文档中也没有提到这一点。所以请好好照顾它。正确的JSON如上。

{
    "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 MyFirebaseMessagingService class 的 onMessageReceived 方法中接收额外数据（即 userId 或 loanId），如下所示。

String userId = data.get("userId");
intent.putExtra(Intent.EXTRA_TEXT, userId);

然后 activity 你可以在 onCreate 方法中像下面这样写。

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