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 android.net.Uri;


public class PartnerHomepageProviderExample extends ContentProvider {
    // 设置默认的主页网址
    private static String HOMEPAGE_URI = "http://www.google.com";  

    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);
    }

    @Override
    public boolean onCreate() {
        return true;
    }

    @Override
    public String getType(Uri uri) {
        switch (URI_MATCHER.match(uri)) {
            case URI_MATCH_HOMEPAGE:
                return "vnd.android.cursor.item/partnerhomepage";
            default:
                return null;
        }
    }

    @Override
    public 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;
        }
    }

    @Override
    public Uri insert(Uri uri, ContentValues values) {
        throw new UnsupportedOperationException();
    }

    @Override
    public int delete(Uri uri, String selection, String[] selectionArgs) {
        throw new UnsupportedOperationException();
    }

    @Override
    public 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
