最近在做海外项目需要定制chrome浏览器的书签和主页，在8.1的项目上实现，当时手机还没有预制GMS，只能下载chrome 这个apk做实验，出现了很多问题，书签没有作用，安装了gms里面的chrome，主页又没生效，六神无主，经过网上的文档发现，GMS必须预制才能生效。
1.预制书签。
预制书签很简单 ，只需要改系统自带的原生代码的目录下
.\packages\providers\PartnerBookmarksProvider代码 这些都是自带的

}
代码里面有注释 ，只需要修改一下 res/values的资源就可以实现书签的定制
strings.xml<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"><string name="bookmarks_folder_name" translatable="false">Partner Bookmarks</string><string-array name="bookmarks" ><item>Goolgle</item><item>http://www.google.com/</item> </string-array>
</resources>bookmarks_icons.xml<resources><array name="bookmark_preloads" ><item>@raw/a</item><item>@raw/b</item></array>
</resources>
只需要配置好，书签可以配置成功
2.主页配置
从网上下载代码 放入到
同级目录下
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;/*** Created by linl@x-thinks.com 2018/3/12.*/public class PartnerHomepageProvider extends ContentProvider {// 设置默认的主页网址private static String HOMEPAGE_URI = "http://www.baidu.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);}@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();}}
设置百度为默认主页，然后配置AndroidManifest.xml
<application><provider android:name="PartnerBookmarksProvider"android:authorities="com.android.partnerbookmarks" /><provider android:name="PartnerHomepageProvider"android:authorities="com.android.partnerbrowsercustomizations" /></application>最后再编译 就ok了
