步骤1定义一个java类PartnerHomepageProviderExample.java 文件，代码如下：
定义好之后拷贝到源码环境该目录下： \packages\providers\PartnerBookmarksProvider\src\com\android\providers\partnerbookmarks\PartnerHomepageProviderExample.java
package com.android.providers.partnerbookmarks;import android.content.ContentProvider;import android.content.ContentValues;import android.content.UriMatcher;import android.database.Cursor;import android.database.MatrixCursor;import .Uri;public class PartnerHomepageProviderExample extends ContentProvider {// 设置默认的主页网址private static String HOMEPAGE_URI = "";
private static final int URI_MATCH_HOMEPAGE = 0;private static final UriMatcher URI_MATCHER = new UriMatcher(UriMatcher.NO_MATCH);static {URI_MATCHER.addURI("com.android.partnerbrowsercustomizations", "homepage",URI_MATCH_HOMEPAGE);}@Overridepublic boolean onCreate() {return true;}@Overridepublic String getType(Uri uri) {switch (URI_MATCHER.match(uri)) {case URI_MATCH_HOMEPAGE:return "vnd.android.cursor.item/partnerhomepage";default:return null;}}@Overridepublic Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs,String sortOrder) {switch (URI_MATCHER.match(uri)) {case URI_MATCH_HOMEPAGE:MatrixCursor cursor = new MatrixCursor(new String[] { "homepage" }, 1);cursor.addRow(new Object[] { HOMEPAGE_URI });return cursor;default:return null;}}@Overridepublic Uri insert(Uri uri, ContentValues values) {throw new UnsupportedOperationException();}@Overridepublic int delete(Uri uri, String selection, String[] selectionArgs) {throw new UnsupportedOperationException();}@Overridepublic int update(Uri uri, ContentValues values, String selection, String[] selectionArgs) {throw new UnsupportedOperationException();}}
找到定义AndroidManifet.xml文件, 路径： \packages\providers\PartnerBookmarksProvider\AndroidManifest.xml： 找到注释开始结束位置添加代码
