亚马逊火 OS WebViews

从 3.3.0 开始，你可以使用Cordova作为亚马逊火 OS 应用程式中的一个元件。亚马逊火 OS 是指这种元件 CordovaWebView 。 CordovaWebView扩展建立在开放原始码铬专案的亚马逊 web 视图。通过利用此功能，您的 web 应用程式可以利用最新的 HTML5 web 标准在现代 web 运行时引擎中运行。

如果你是亚马逊火 OS 不熟悉，您应首先熟悉亚马逊火 OS 平台指南和有最新的 Sdk 安装之前您尝试嵌入 web 视图的更多不寻常的发展方案。

系统必备元件

Cordova 3.3.0 或更高
Android SDK 更新到最新的 SDK
亚马逊 web 视图 SDK

在亚马逊火 OS 专案中使用 CordovaWebView 的指南

要按照这些说明进行操作，请确保您有最新的Cordova分布。从cordova.apache.org下载并解压其亚马逊火 OS 套装程式。
下载并展开亚马逊 web 视图 SDK ，然后复制到 awv_interface.jar /framework/libs 目录。创建库 / 资料夹如果它不存在。
导航到包的 /framework 目录，运行 ant jar 。它创建了Cordova .jar 档中，形成了作为/framework/cordova-x.x.x.jar.
复制 .jar 到 Android 专案档案 /libs 目录。

将以下内容添加到应用程式的 /res/xml/main.xml 档中，与 layout_height 、 layout_width 和 id 修改，以适合应用程式：

<org.apache.cordova.CordovaWebView
    android:id="@+id/tutorialView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

修改您的活动，使它实现了 CordovaInterface 。您应该执行包括的方法。您可能希望将它们从复制 /framework/src/org/apache/cordova/CordovaActivity.java ，或执行这些靠你自己。下面的代码片段显示了一个基本的应用程式，使用该介面。请注意如何引用的视图 id 匹配 id 在上面所示的 XML 片段中指定的属性：

public class CordovaViewTestActivity extends Activity implements CordovaInterface {
    CordovaWebView cwv;
    /* Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        cwv = (CordovaWebView) findViewById(R.id.tutorialView);
        Config.init(this);
        cwv.loadUrl(Config.getStartUrl());
    }

如果您使用的相机，你应该也可以实现这：

    @Override
    public void setActivityResultCallback(CordovaPlugin plugin) {
        this.activityResultCallback = plugin;
    }
    /**
     * Launch an activity for which you would like a result when it finished. When this activity exits,
     * your onActivityResult() method is called.
     *
     * @param command           The command object
     * @param intent            The intent to start
     * @param requestCode       The request code that is passed to callback to identify the activity
     */
    public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {
        this.activityResultCallback = command;
        this.activityResultKeepRunning = this.keepRunning;

        // If multitasking turned on, then disable it for activities that return results
        if (command != null) {
            this.keepRunning = false;
        }

        // Start activity
        super.startActivityForResult(intent, requestCode);
    }

    @Override
    /**
     * Called when an activity you launched exits, giving you the requestCode you started it with,
     * the resultCode it returned, and any additional data from it.
     *
     * @param requestCode       The request code originally supplied to startActivityForResult(),
     *                          allowing you to identify who this result came from.
     * @param resultCode        The integer result code returned by the child activity through its setResult().
     * @param data              An Intent, which can return result data to the caller (various data can be attached to Intent "extras").
     */
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        CordovaPlugin callback = this.activityResultCallback;
        if (callback != null) {
            callback.onActivityResult(requestCode, resultCode, intent);
        }
    }

最后，请记住，添加执行绪池，否则外挂程式有没有线程上运行：

    @Override
    public ExecutorService getThreadPool() {
        return threadPool;
    }

将您的应用程式的 HTML 和 JavaScript 档案复制到您的亚马逊火 OS 专案 /assets/www 目录。
复制 config.xml 从 /framework/res/xml 到您的专案的 /res/xml 目录。
