Android Hybird架构之整合XwalkView，让你的App内置chromium内核

使用XwalkView的目的无非是为了提升Android4.4以下版本（非chromium内核）的Html5渲染性能，并且能够使得H5页面在众多定制化的ROM上拥有一致的体验。
当然了，App内置Chromuim内核的缺点也是显而易见的，那就是App的包体积会增大20M左右。但是从hybrid应用开发来看，牺牲掉的体积所换来的优秀体验还是值得的。微信内置了QQ浏览器X5内核也充分说明了这一点。

1.下载XWalkView

https://download.01.org/crosswalk/releases/crosswalk/android/maven2/org/xwalk/xwalk_core_library/
2.新建项目XWalkViewDemo，并引入和依赖arr包

3.布局文件中引入xwalk activity_main.xml

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="zjsx.xwalkviewdemo.MainActivity">

    <org.xwalk.core.XWalkView
        android:id="@+id/xwalkView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
</RelativeLayout>

4.使用xwalkview加载链接 MainActivity.java

public class MainActivity extends AppCompatActivity {
    XWalkView mXwalkView;

    class MyResourceClient extends XWalkResourceClient {
        MyResourceClient(XWalkView view) {
            super(view);
        }
    }

    class MyUIClient extends XWalkUIClient {
        MyUIClient(XWalkView view) {
            super(view);
        }
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mXwalkView = (XWalkView) findViewById(R.id.xwalkView);
        mXwalkView.setResourceClient(new MyResourceClient(mXwalkView));
        mXwalkView.setUIClient(new MyUIClient(mXwalkView));
        mXwalkView.load("http://www.bing.com", null);
    }

    @Override
    protected void onPause() {
        super.onPause();
        if (mXwalkView != null) {
            mXwalkView.pauseTimers();
            mXwalkView.onHide();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (mXwalkView != null) {
            mXwalkView.resumeTimers();
            mXwalkView.onShow();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mXwalkView != null) {
            mXwalkView.onDestroy();
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (mXwalkView != null) {
            mXwalkView.onActivityResult(requestCode, resultCode, data);
        }
    }

    @Override
    public void onNewIntent(Intent intent) {
        if (mXwalkView != null) {
            mXwalkView.onNewIntent(intent);
        }
    }
}
