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>

<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);
	}

 <plugin name="MyPlugin" value="com.fanfq.phonegap.plugin.MyPlugin"/>

        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 {

            } else {

            }
        } catch (JSONException e) {
            return new PluginResult(PluginResult.Status.JSON_EXCEPTION,"error");
        }
    }
    

}
