PendingIntent不适用于Android O.(PendingIntent is not working on Android O)

 我在我的申请中有下载通知。 我通过调用addAction()方法向NotificationCompat.Builder添加了“Cancel”按钮。 但按钮无法在Android O设备上运行。 当我按“取消”按钮时没有任何反应。 但按钮在Android <O上工作。 
 
  
 

 我的Notification ： 
 
NotificationCompat.Builder notification = new NotificationCompat.Builder(context, channelId)
            .setContentTitle(title)
            .setSmallIcon(R.drawable.network_download)
            .setContentText(contentText)
            .setOngoing(true)
            .setContentIntent(null)
            .addExtras(idBundle)
            .addAction(R.drawable.cancel, context.getString(R.string.cancel), getCancelPendingIntent(context, id))
            .setProgress(100, 30, true);
 
 我的PendingIntent ： 
 
private PendingIntent getCancelPendingIntent(Context context, int id){
    return PendingIntent.getBroadcast(
            context, id, new Intent("CANCEL_DOWNLOAD").putExtra("id", id), PendingIntent.FLAG_UPDATE_CURRENT);
}
 
 我还有NotificationReceiver ： 
 
public static class NotificationReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if ("CANCEL_DOWNLOAD".equals(action) && context != null){
            int id = intent.getIntExtra("id", -1);
            NotificationManager mgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            if (mgr != null)
                mgr.cancel(id);
            FtpManager.getInstance(new AppExecutors(), CredentialsManager.getInstance().getCredentials(context))
                    .cancelDownloading();
        }
    }
}
 
 在Manifest文件中我有： 
 
<receiver
        android:name="eu.warble.pjapp.util.NotificationsManager$NotificationReceiver"
        android:exported="false">
        <intent-filter>
            <action android:name="CANCEL_DOWNLOAD" />
        </intent-filter>
</receiver>

I have download notification in my application. I've added "Cancel" button to NotificationCompat.Builder by calling addAction() method. But button not working on Android O device. When I press "Cancel" button nothing happens. But button working on Android < O.
 
 

My Notification:
 
NotificationCompat.Builder notification = new NotificationCompat.Builder(context, channelId)
            .setContentTitle(title)
            .setSmallIcon(R.drawable.network_download)
            .setContentText(contentText)
            .setOngoing(true)
            .setContentIntent(null)
            .addExtras(idBundle)
            .addAction(R.drawable.cancel, context.getString(R.string.cancel), getCancelPendingIntent(context, id))
            .setProgress(100, 30, true);
 
My PendingIntent :
 
private PendingIntent getCancelPendingIntent(Context context, int id){
    return PendingIntent.getBroadcast(
            context, id, new Intent("CANCEL_DOWNLOAD").putExtra("id", id), PendingIntent.FLAG_UPDATE_CURRENT);
}
 
Also I have NotificationReceiver :
 
public static class NotificationReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if ("CANCEL_DOWNLOAD".equals(action) && context != null){
            int id = intent.getIntExtra("id", -1);
            NotificationManager mgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            if (mgr != null)
                mgr.cancel(id);
            FtpManager.getInstance(new AppExecutors(), CredentialsManager.getInstance().getCredentials(context))
                    .cancelDownloading();
        }
    }
}
 
In Manifest file I have :
 
<receiver
        android:name="eu.warble.pjapp.util.NotificationsManager$NotificationReceiver"
        android:exported="false">
        <intent-filter>
            <action android:name="CANCEL_DOWNLOAD" />
        </intent-filter>
</receiver>
