title: 亚马逊火 OS 外挂程式

亚马逊火 OS 外挂程式

按照有关的开发自订外挂程式概述 Android 外挂程式指南中提供的说明。

回声亚马逊火 OS 外挂程式示例

若要匹配的 JavaScript 介面*回波*特征描述的应用程式外挂程式，使用 plugin.xml 来注入 feature 到本地平台规范 config.xml 档：

<platform name="amazon-fireos">
    <config-file target="config.xml" parent="/*">
        <feature name="Echo">
            <param name="android-package" value="org.apache.cordova.plugin.Echo"/>
        </feature>
    </config-file>
</platform>

然后添加以下到 src/org/apache/cordova/plugin/Echo.java 档：

package org.apache.cordova.plugin;

import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CallbackContext;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

/**
 * This class echoes a string called from JavaScript.
 */
public class Echo extends CordovaPlugin {

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        if (action.equals("echo")) {
            String message = args.getString(0);
            this.echo(message, callbackContext);
            return true;
        }
        return false;
    }

    private void echo(String message, CallbackContext callbackContext) {
        if (message != null && message.length() > 0) {
            callbackContext.success(message);
        } else {
            callbackContext.error("Expected one non-empty string argument.");
        }
    }
}

如果你想要重用的亚马逊火 OS 平台 Android 外挂程式代码然后修改通过指向 android 特定的原始档案。例如，

<platform name="amazon-fireos">
    <config-file target="config.xml" parent="/*">
        <feature name="Echo">
            <param name="android-package" value="org.apache.cordova.plugin.Echo"/>
        </feature>
    </config-file>
    <source-file src="src/android/Echo.java" target-dir="src/org/apache/cordova/plugin" />
</platform>

如果你想要编写自订的外挂程式的亚马逊火 OS 平台，然后创建一个名为资料夹 amazon 下你的外挂程式 src / 资料夹和修改通过为指向 amazon 特定的原始档案。 例如，

<platform name="amazon-fireos">
    <config-file target="config.xml" parent="/*">
        <feature name="Echo">
            <param name="android-package" value="org.apache.cordova.plugin.Echo"/>
        </feature>
    </config-file>
    <source-file src="src/amazon/Echo.java" target-dir="src/org/apache/cordova/plugin" />
</platform>

在你的外挂程式中使用亚马逊 web 视图

科尔多瓦的亚马逊火 OS 使得使用的基于开放源码铬专案的自订亚马逊 web 视图。它是 GPU 加速和优化的流体性能上点燃火。
