如何从前台服务启动 Flutter 应用程序

Question

我有一个 Flutter 应用，它运行一个永无止境的前台服务，它的定义如下：

    private void startForeground() {
    Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);
    startForeground(NOTIF_ID, new NotificationCompat.Builder(this,
            NOTIF_CHANNEL_ID)
            .setOngoing(true)
            .setContentTitle("service")
            .setContentText("Service is running background")
            .setContentIntent(pendingIntent)
            .build());
}

然后我开始这样的服务：

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
    Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.drawable.smile)
            .setContentTitle("App is running in background")
            .setPriority(NotificationManager.IMPORTANCE_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build();
    startForeground(2, notification);

我的前台服务一直在显示通知。

是否可以在用户按下前台服务显示的通知时启动 Flutter 应用程序，即使 Flutter 应用程序没有在后台运行？谢谢。

要在单击通知时启动Activity，您可以使用PendingIntent。您已经在第一个示例中实现了此功能，但这里有一些链接。 Android docsStackoverflow question

Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);
builder.setContentIntent(pendingIntent);
