在 Localytics 推送通知中实现深度链接

Question

我正在尝试通过 Android 中的 Localytics 推送通知实现深度链接。在下面的代码中，我能够接收我在创建推送通知时通过 Localytics 仪表板发送的键值对。 但是，我的要求是根据我在推送通知中收到的键/值对打开一个特定的活动。

     public class GCMReceiver extends BroadcastReceiver {
     String deeplink_key = "KEY_DEEPLINK";
     public static final String CUSTOM_INTENT ="com.mypackage.action.TEST";

     @Override
     public void onReceive(Context context, Intent intent) {
    Bundle extras = intent.getExtras();
    String deeplinkValues = extras.getString(deeplink_key);
    Log.i("BASE", "deeplinkValues: " + deeplinkValues);
    String action = intent.getAction();
    Uri data = intent.getData();

    Intent gotoOffersIntent = new Intent(context,OffersDisplayActivity.class);
    gotoOffersIntent.putExtra(deeplink_key, deeplinkValues);
//  gotoOffersIntent.setAction(CUSTOM_INTENT);
    /*The below line opens the OffersDisplayActvity directly when Push notification is received*/
    context.startActivity(gotoOffersIntent);


//  context.sendOrderedBroadcast(gotoOffersIntent, null);

    PushReceiver pushReceiver = new PushReceiver();
    pushReceiver.onReceive(context, intent);

    GCMBroadcastReceiver gcmBroadcastReceiver = new GCMBroadcastReceiver();
    gcmBroadcastReceiver.onReceive(context, intent);

}
}

使用上面的代码，我可以在收到 PushNotification 时打开 OffersDisplayActivity，但我希望在单击推送通知时打开 OffersDisplayActivity。

请帮帮我。谢谢！

您不需要深层链接来满足您的要求。 Localytics 的人有时会误导开发人员，说您需要对自定义类型的通知进行深度链接。

我们使用 localytics 完成了您希望在应用中执行的相同操作。 1) 在您已经实现的 GCMBroadcastReciever 中接收 Localytics 信息。 2）在您的消息中保留一个字段以识别您要打开的活动

如果您通过以下操作添加了任何额外的类来接收意图

com.google.android.c2dm.intent.RECEIVE

除了你的 GCMReceiver 然后删除它..

这样，所有通知要么来自您的服务器，要么来自本地化，它将在 onReceive 方法中接收。

这是我们为 localytics 和我们自己的服务器所做的完整示例..

Android Manifest.xml

<service
            android:name=".gcm.CustomInstanceIDListenerService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.gms.iid.InstanceID" />
            </intent-filter>
        </service>

        <receiver
            android:name="com.google.android.gms.gcm.GcmReceiver"
            android:permission="com.google.android.c2dm.permission.SEND">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <!-- for Gingerbread GSF backward compat -->
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
                <category android:name="com.nearfox.android" />
            </intent-filter>
        </receiver>

        <service android:name=".gcm.CustomGCMListenerService">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>
        <service
            android:name=".gcm.RegistrationIntentService"
            android:exported="false" />

在 CustomGCMListenerService.java 中

public class CustomGCMListenerService extends GcmListenerService {

    private static final String TAG = "CustomGCMListener";

    public interface MESSAGE_TYPE {
        String NOTIFICATION_NEWS = "news_notification";
        String NOTIFICATION_EVENT = "event_notification";
    }

    @Override
    public void onMessageReceived(String from, Bundle data) {
        if (data.containsKey("msg_type") && data.getString("msg_type") != null) {
            String messageType = data.getString("msg_type");
            if (messageType.equals(MESSAGE_TYPE.NOTIFICATION_NEWS)) {
                String newsJson = data.getString("news_body");
                try {
                    JSONObject jsonObject = new JSONObject(newsJson).getJSONObject("message");
                    generateNotification(this, jsonObject.getString("title"), "", MESSAGE_TYPE.NOTIFICATION_NEWS, data);
                } catch (JSONException e) {
                    e.printStackTrace();
                    Log.i(TAG, "Notification Parsing Error");
                    return;
                }
            } else if (messageType.equals(MESSAGE_TYPE.NOTIFICATION_EVENT)) {
                String newsJson = data.getString("body");
                try {
                    JSONObject jsonObject = new JSONObject(newsJson).getJSONObject("message");
                    generateNotification(this, jsonObject.getString("title"), "", MESSAGE_TYPE.NOTIFICATION_EVENT, data);
                } catch (JSONException e) {
                    e.printStackTrace();
                    Log.i(TAG, "Notification Parsing Error");
                    return;
                }
            }
        }
    }


    public static void generateNotification(Context context, String message, String ids, String messageType, Bundle data) {
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context);
        notificationBuilder.setSmallIcon(R.drawable.small_notification_icon);
        notificationBuilder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.app_icon));
        String title = context.getString(R.string.app_name);
        notificationBuilder.setContentTitle(title);
        notificationBuilder.setContentText(message);
        Notification notification ;


        if (messageType.equals(MESSAGE_TYPE.NOTIFICATION_NEWS)) {
            Intent notificationIntent = new Intent(context, SingleNewsActivity.class);
            notificationIntent.putExtra("source", "notification");
            notificationIntent.putExtra("news_title", message);
            PendingIntent intent =
                    PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            notificationBuilder.setContentIntent(intent);
        } else if (messageType.equals(MESSAGE_TYPE.NOTIFICATION_EVENT)) {
            Intent notificationIntent = new Intent(context, SingleEventActivity.class);
            notificationIntent.putExtra("source", "notification");
            notificationIntent.putExtra("event_title", data);
            PendingIntent intent =
                    PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            notificationBuilder.setContentIntent(intent);
        }
        notificationBuilder.setContentText(message);
        notificationBuilder.setStyle(new android.support.v4.app.NotificationCompat.BigTextStyle().bigText(message));
        notification = notificationBuilder.build();
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);

    }
}

因此，您可以在此处查看是从 localytics 还是从您自己的服务器发送包含字段 "message_type"="news_notification" 的 GCM 消息，然后用户单击通知将打开 SingleNEwsActivity 如果"message_type"=event_notification" 那么它将打开 SingleEventActivity.. 在这里你也可以使用notificationIntent.putExtra() 传递额外的数据

Answer 2

比较您的键值对并基于它，在生成推送通知时从 Intent 调用期望活动。 当用户点击通知时它会调用它。

// Set the action to take when a user taps the notification
    Intent resultIntent = new Intent(context, LoginActivity.class);
    resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    if (notificationObj!=null) {
        resultIntent.putExtra(UserDefault.pushJSONObj, notificationObj);
    }

    PendingIntent resultPendingIntent = PendingIntent.getActivity(context, 0, resultIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);

这里的 notificationObj 是你想要传递给你的活动的任何参数。
