Android壁纸应用程序错误提取JSON

时间：2017-07-25 09:36:36

标签： java android json

我正在尝试制作一个壁纸应用程序。我试图使用之前称为picasa的谷歌照片中的json来获取照片。

我把专辑公开制作了他们

我正在关注GeekMentors

的教程

当我运行geekmentors提供的源代码时，我能够在我的应用程序上获取壁纸，但是当我运行替换用户ID 公共静态最终字符串PICASA_USER =＆＃34; freewallpapersapp＆＃34 ;; 到公共静态最终字符串PICASA_USER =＆＃34; fbphotocomments＆＃34 ;; 在 APPConst.java 中显示错误但不提取照片。

请帮帮我:)

AppConst.java 

package com.geekmentors.wallpaperfreeapp.app;

/**
 * Created by geekmentors on 1/26/16.
 */
public class AppConst {
    // Number of columns of Grid View
    // by default 2 but user can configure this in settings activity
    public static final int NUM_OF_COLUMNS = 2;

    // Gridview image padding
    public static final int GRID_PADDING = 0; // in dp

    // Gallery directory name to save wallpapers
    public static final String SDCARD_DIR_NAME = "Awesome Wallpapers";

    // Picasa/Google web album username
    public static final String PICASA_USER = "freewallpapersapp";
**strong text**
    // Public albums list url
    public static final String URL_PICASA_ALBUMS = "https://picasaweb.google.com/data/feed/api/user/_PICASA_USER_?kind=album&alt=json";

    // Picasa album photos url
    public static final String URL_ALBUM_PHOTOS = "https://picasaweb.google.com/data/feed/api/user/_PICASA_USER_/albumid/_ALBUM_ID_?alt=json";

    // Picasa recenlty added photos url
    public static final String URL_RECENTLY_ADDED = "https://picasaweb.google.com/data/feed/api/user/_PICASA_USER_?kind=photo&alt=json";
}

  3. 然后保持不变。检查下图：
