Question

我无法使用API 26更新该应用。当我尝试运行项目

时出现以下错误

错误：

“ ServerRunningNotification.java”：错误：找不到符号方法 setLatestEventInfo（Context，CharSequence，CharSequence，PendingIntent）

这是我的代码段，其中有错误

代码：

public class ServerRunningNotification extends BroadcastReceiver {
    private static final String TAG = ServerRunningNotification.class.getSimpleName();

    private final int NOTIFICATIONID = 7890;
    public String iptext;
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "onReceive broadcast: " + intent.getAction());
        if (intent.getAction().equals(FtpServerService.ACTION_STARTED)) {
            setupNotification(context);
        } else if (intent.getAction().equals(FtpServerService.ACTION_STOPPED)) {
            clearNotification(context);
        }
    }

    @SuppressWarnings("deprecation")
    private void setupNotification(Context context) {
        Log.d(TAG, "Setting up the notification");
        // Get NotificationManager reference
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager nm = (NotificationManager) context.getSystemService(ns);

        // get ip address
        InetAddress address = FtpServerService.getLocalInetAddress();
        if (address == null) {
            Log.w(TAG, "Unable to retreive the local ip address");
            return;
        }
         iptext = "ftp://" + address.getHostAddress() + ":"
                + Settings.getPortNumber() + "/";

        // Instantiate a Notification
        int icon = R.drawable.ftp_icon;
        CharSequence tickerText = String.format(
                context.getString(R.string.notif_server_starting), iptext);
        long when = System.currentTimeMillis();
        Notification notification = new Notification(icon, tickerText, when);

        // Define Notification's message and Intent
        CharSequence contentTitle = context.getString(R.string.notif_title);
        CharSequence contentText = String.format(context.getString(R.string.notif_text),
                iptext);

        Intent notificationIntent = new Intent(context, FTP_Start_Stop.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                notificationIntent, 0);
        notification
                .setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        notification.flags |= Notification.FLAG_ONGOING_EVENT;

        // Pass Notification to NotificationManager
        nm.notify(NOTIFICATIONID, notification);

        Log.d(TAG, "Notication setup done");
    }

    private void clearNotification(Context context) {
        Log.d(TAG, "Clearing the notifications");
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager nm = (NotificationManager) context.getSystemService(ns);
        nm.cancelAll();
        Log.d(TAG, "Cleared notification");
    }
}

根据here，setLatestEventInfo(Context,CharSequence,CharSequence,PendingIntent)方法已在Android M（API 23）中删除。因此它不适用于23以上的API版本。

错误：找不到符号方法setLatestEventInfo（Context，CharSequence，CharSequence，PendingIntent）
