Question

我在Android应用中实施了Google Cloud Messaging。当我打开应用程序时发送带有JSON的消息时，它与我关闭应用程序时的行为不同。

当我将应用打开并收到通知时，它会启动我希望它启动的意图。当我收到通知已关闭时，我点击通知，它会打开主要意图。当我关闭应用程序并收到推送通知时，如何说出需要打开哪个意图？

MyGcmListenerService中的代码

public class MyGcmListenerService extends GcmListenerService {

    private static final String TAG = "MyGcmListenerService";
    File fileDir, file;
    String filename, filestring;

    /**
     * Called when message is received.
     *
     * @param from SenderID of the sender.
     * @param data Data bundle containing message data as key/value pairs.
     *             For Set of keys use data.keySet().
     */

    @Override
    public void onMessageReceived(String from, Bundle data) {

        Bundle notification = data.getBundle("notification");
        String title = notification.getString("title");
        String naam = notification.getString("naam");
        String nfcId = notification.getString("nfcId");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Title: " + title);
        Log.d(TAG, "Naam: " + naam);
        Log.d(TAG, "nfcId: " + nfcId);

        if (from.startsWith("/topics/")) {

        } else {
            filename = "gegevensOverledene";
            ReadWriteFile readWriteFile = new ReadWriteFile(getApplicationContext());
            readWriteFile.writeFileOverledene(filename, naam);
        }

        sendNotification(title, naam, nfcId);
    }

    /**
     * Create and show a simple notification containing the received GCM message.
     */
    private void sendNotification(String title, String naam, String nfcId) {
        Intent intent = new Intent(this, PinLoginActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra("naam", naam);
        intent.putExtra("nfcId",nfcId);
        intent.putExtra("Class",NieuweOverledeneActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(naam)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }
}

我发送的JSON，请注意我故意遗漏了token_mobile

{
    "to": "TOKEN_MOBILE****************",
    "notification": {
        "title": "Nieuwe overledene",
        "body": "Henk",
        "naam": "Henk",
        "nfcId": "80-40-A3-4A-C2-D6-04"
    }
}

Answer 1

您正在发送通知消息。详细了解如何处理通知消息here。

当您的应用位于前台时，通知消息会传递到您的onMessageReceived回调。在那里，您可以决定接收消息应该做什么，例如：生成并显示通知或与您的应用服务器同步或等等。

当您的应用在后台时，通知消息会根据＆＃34;通知＆＃34;中传递的属性自动生成通知。您的下游邮件请求的对象，在这种情况下不会调用onMessageReceived 。如果您查看reference docs通知消息，您会看到一个名为click_action的字段，您可以使用此字段来定义在点击自动生成的通知时启动的活动：

在Android上，如果已设置此选项，则会为具有匹配意图过滤器的活动启用此选项在用户点击通知时启动。

如果没有设置，则会启动主Activity，这就是您现在所看到的。

注意：此行为仅适用于通知消息，如果您仅发送数据消息，则所有已发送的消息都将导致onMessageReceived被调用。

检查以下

/**
 * Create and show a simple notification containing the received GCM message.
 */
private void sendNotification(String title, String naam, String nfcId) {

    //Create the intent according to your condition and pass it to pendingintent.

    Intent intent = new Intent(this, PinLoginActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("naam", naam);
    intent.putExtra("nfcId",nfcId);
    intent.putExtra("Class",NieuweOverledeneActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.mipmap.ic_launcher)
        .setContentTitle(title)
        .setContentText(naam)
        .setAutoCancel(true)
        .setSound(defaultSoundUri)
        .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

当应用在后台
