java - 如何在服务中创建 XWalkView？

Question

我正在努力用 Crosswalk 的实现替换我们 Android 应用中的原生 webview。

我们已经能够让应用程序的大部分功能正常工作，但在服务中创建 XWalkView 仍然是我们试图解决的问题。创建 Webview 不是问题，但 XWalkView 需要使用 Activity 上下文。如果这里有人遇到过这个问题并且知道可能的解决方案或解决方法，我将不胜感激。谢谢，如果您需要任何其他信息，请随时询问。

So, what is crosswalk and why do I care? Take a look at the website: https://crosswalk-project.org/

CrossWalk is a HTML5 runtime, you can use it to create HTML5 applications with 'native features' You can use CrossWalk to create HTML5-only applications for Android (x86 and arm architectures) and Tizen but you can also use CrossWalk as a View within an android project.

This means you can replace Android WebView with XWalkView and get some extra features like:

-WebGl

-WebRTC

-WebAudio

How do I embed a CrossWalk WebView, from now on a XWalkView, inside an Android application to have all this goodies on my hybrid application (Android Native with html5 features)

First you have to download the runtime:

https://crosswalk-project.org/#documentation/downloads

Download any of the Android(ARM) versions.

Inside the file is everything you need to start working in an html5 application.

For this test we'll need to import the xwalk-core-library project inside our Eclipse

Create a new Android project with a basic Activity link it with the library and put this code in the Activity:

package com.example.xwalkwithlibrary;
import org.xwalk.core.XWalkView;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.LinearLayout;

public class XWalkEmbedLib extends Activity {
    private LinearLayout commentsLayout;
    private XWalkView xWalkWebView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_xwalk_embed_lib);
         commentsLayout=(LinearLayout)findViewById(R.id.principal);
         xWalkWebView = new XWalkView(this, this);
         xWalkWebView.load("file:///android_asset/www/index.html", null);
         commentsLayout.addView(xWalkWebView);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.xwalk_embed_lib, menu);
        return true;
    }
}

Put this on your main layout

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".XWalkMain" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
                android:id="@+id/principal"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginLeft="35dp"
        android:layout_marginTop="86dp"
        android:orientation="vertical" >
    </LinearLayout>

</RelativeLayout>

finally inside your /assets/www folder put your html stuff and that's it
