phonegap-plugin

说白就是使用js调用java代码，蛮有意思的，不难看出phonegap的很多类库都是使用plugin的模式做的。

index.html
<!DOCTYPE html><html><head><title>Storage Example</title><script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script><script type="text/javascript" charset="utf-8">// Wait for Cordova to load//document.addEventListener("deviceready", onDeviceReady, false);// Cordova is ready//function onDeviceReady() {PhoneGap.exec(successFunction, failFunction, "MyPlugin","echo",["a","b"]);}function successFunction(e){alert("success:"+e);}function failFunction(e){alert("fail:"+e);}</script></head><body><h1>Example</h1>Plugin</body></html>

res/xml/config.xml *这部需要注意一下，不要忘记配置
<plugin name="MyPlugin" value="com.fanfq.phonegap.plugin.MyPlugin"/>

src/com/fanfq/phonegap/plugin/MyPlugin.java
package com.fanfq.phonegap.plugin;import org.apache.cordova.api.Plugin;import org.apache.cordova.api.PluginResult;import org.json.JSONArray;import org.json.JSONException;import org.json.JSONObject;public class MyPlugin extends Plugin { /** * Executes the request and returns PluginResult. * * @param action The action to execute. * @param args JSONArry of arguments for the plugin. * @param callbackId The callback id used when calling back into JavaScript. * @return A PluginResult object with a status and message. */ public PluginResult execute(String action, JSONArray args, String callbackId) { try { if (action.equals("echo")) { String echo = args.getString(0); if (echo != null && echo.length() > 0) { return new PluginResult(PluginResult.Status.OK, "hello fanfq!"); } else { return new PluginResult(PluginResult.Status.ERROR); } } else { return new PluginResult(PluginResult.Status.INVALID_ACTION); } } catch (JSONException e) { return new PluginResult(PluginResult.Status.JSON_EXCEPTION,"error"); } } }
