建立自己的ContentProvider
public class LauncherLiveFolderProvider extends ContentProvider//自己建立一个类，继承自ContentProvider, 默认就有这些需要实现的方法//如果只是用来读取数据的话，实现query和getType什么的就基本齐活儿了。//转一个最近写的把sms和bookmark做到livefolder的代码，参考ahome和contacts源码弄的provider定义的比较随意，似乎丑陋了点。。。源码没读多少，sms那块儿完全就是自己看了数据库表项之后随便凑合的。1。LauncherLiveFolderAdapterURI.java。 全是变量。　　package g.LauncherLiveFolderA
import android.net.U
public class LauncherLiveFolderAdapterURI {
public static final String AUTHORITY_SMS="livefolder.sms";
public static final String AUTHORITY_BOOKMARK="livefolder.browser";
public static final Uri BOOKMARK_ALL_CONTNET_URI = Uri.parse("content://"+AUTHORITY_BOOKMARK+"/bookmarks/all");
public static final Uri BOOKMARK_RECENTVIST_CONTNET_URI = Uri.parse("content://"+AUTHORITY_BOOKMARK+"/bookmarks/recently_visited");
public static final Uri BOOKMARK_MOSTVIST_CONTNET_URI = Uri.parse("content://"+AUTHORITY_BOOKMARK+"/bookmarks/most_visited");
public static final Uri SMS_ALL_CONTENT_URI = Uri.parse("content://"+AUTHORITY_SMS+"/all");
= inbox + sent
public static final Uri SMS_INBOX_CONTENT_URI = Uri.parse("content://"+AUTHORITY_SMS+"/inbox");
public static final Uri SMS_SENT_CONTENT_URI = Uri.parse("content://"+AUTHORITY_SMS+"/sent");
public static final Uri SMS_UNREAD_CONTENT_URI = Uri.parse("content://"+AUTHORITY_SMS+"/unread");
// unread & inbox
public static final Uri CONTNET_SMS_URI =
Uri.parse("content://"+AUTHORITY_SMS);
public static final int SMS_ALL = 101;
public static final int SMS_INBOX = 102;
public static final int SMS_UNREAD = 103;
public static final int SMS_SENT = 104;
public static final int BOOKMARK_ALL = 111;
public static final int BOOKMARK_RECENT = 112;
public static final int BOOKMARK_MOST = 113;
public static final String BOOKMARK_CONTENT_TYPE = "vnd.android.cursor.dir/bookmark";
public static final String BOOKMARK_CONTENT_TYPE_ITEM=
"vnem/bookmark";
public static final String SMS_CONTENT_TYPE = "vnd.android.cursor.dir/mms-sms";
public static final String SMS_CONTENT_TYPE_ITEM="vnem/mms-sms";

　　您好，我自己写了一个ContentProvider-MyProvider在mainfest.xml文件中通过android:name="android.permission.WRITE_MYPERMISSION"设置了写权限，然后通过自己写的另一个apk去访问这个provider的时候，通过在mainfest&xml文件中添加&uses-permission android:name="android.permission.WRITE_MYPERMISSION"&这样设置了访问权限，但是为什么我的程序已运行还是报错说缺少访问权限啊？您给指点一下？谢谢liuhao51 & &
