Android chrome浏览器的定制

　

android浏览器

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

src\com\Android\providers\partnerbookmark

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 [email protected] 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);
    }
    @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();
    }




}

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
