android原生浏览器代码报错

[示也Shane]

android原生浏览器代码中
EventLog.writeEvent(EventLogTags.BROWSER_BOOKMARK_ADDED, url + "|" + where);
这一句报错怎么解决

package com.android.browser;


import android.util.EventLog;

public class LogTag {

    /**
     * Log when the user is adding a new bookmark.
     *
     * @param url the url of the new bookmark.
     * @param where the location from where the bookmark was added
     */
    public static void logBookmarkAdded(String url, String where) {
    	EventLog.writeEvent(EventLogTags.BROWSER_BOOKMARK_ADDED, url + "|" + where);
    }

    /**
     * Log when a page has finished loading with how much
     * time the browser used to load the page.
     *
     * Note that a redirect will restart the timer, so this time is not
     * always how long it takes for the user to load a page.
     *
     * @param url the url of that page that finished loading.
     * @param duration the time the browser spent loading the page.
