亞馬遜火 OS WebViews

從 3.3.0 開始，你可以使用科爾多瓦作為亞馬遜火 OS 應用程式中的一個元件。 亞馬遜火 OS 是指這種元件 CordovaWebView 。 CordovaWebView擴展建立在開放原始碼鉻專案的亞馬遜 web 視圖。 通過利用此功能，您的 web 應用程式可以利用最新的 HTML5 web 標準在現代 web 運行時引擎中運行。

如果你是亞馬遜火 OS 不熟悉，您應首先熟悉亞馬遜火 OS 平臺指南和有最新的 Sdk 安裝之前您嘗試嵌入 web 視圖的更多不尋常的發展方案。

系統必備元件

在亞馬遜火 OS 專案中使用 CordovaWebView 的指南

  1. 要按照這些說明進行操作，請確保您有最新的科爾多瓦分佈。從cordova.apache.org下載並解壓其亞馬遜火 OS 套裝程式。

  2. 下載並展開亞馬遜 web 視圖 SDK ，然後複製到 awv_interface.jar /framework/libs 目錄。 創建庫 / 資料夾如果它不存在。

  3. 導航到包的 /framework 目錄，運行 ant jar 。它創建了科爾多瓦 .jar 檔中，形成了作為/framework/cordova-x.x.x.jar.

  4. 複製 .jar 到 Android 專案檔案 /libs 目錄。

  5. 將以下內容添加到應用程式的 /res/xml/main.xml 檔中，與 layout_height 、 layout_width 和 id 修改，以適合應用程式：

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

  1. 修改您的活動，使它實現了 CordovaInterface 。 您應該執行包括的方法。 您可能希望將它們從複製 /framework/src/org/apache/cordova/CordovaActivity.java ，或執行這些靠你自己。 下面的代碼片段顯示了一個基本的應用程式，使用該介面。 請注意如何引用的視圖 id 匹配 id 在上面所示的 XML 片段中指定的屬性：

    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());
    }

如果您使用的相機，你應該也可以實現這：

    @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);
        }
    }

最後，請記住，添加執行緒池，否則外掛程式有沒有線程上運行：

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

  1. 將您的應用程式的 HTML 和 JavaScript 檔案複製到您的亞馬遜火 OS 專案 /assets/www 目錄。

  2. 複製 config.xml 從 /framework/res/xml 到您的專案的 /res/xml 目錄。
