cordova混合开发：Android中native调用javascript

function myinit(){
    alert(‘12355‘);
}

//最省事的就是找个现成的插件添加个函数"callJSInit"，能执行注册就可以
cordova.define("插件ID", function(require, exports, module) {
var exec = require(‘cordova/exec‘);
    window.callJSInit = function() {
        cordova.require(‘cordova/channel‘).onCordovaReady.subscribe(function(){
            exec(succeedCallback, null, "PluginName", "callJSInit", []);
            function succeedCallback(message){
        //执行js代码
        eval(message);
        //还可以这样，大胆的发挥你的想象力
        /*
        if(message==‘f1‘)
            alert(1);
        else if(message == ‘f2‘)
            alert(2);
        ……
        */　　　　　　　　　
            }
        });
    }
});

//在app deviceready后执行：
callJSInit()

public class PluginName extends CordovaPlugin {
    private static CallbackContext mCallbackContext;

    @Override
    public boolean execute(String action, final JSONArray args,
            final CallbackContext callbackContext) throws JSONException {
        if (action.equals("callJSInit")) {
            mCallbackContext = callbackContext;    //拿到回调对象并保存
            //PluginResult dataResult = new PluginResult(PluginResult.Status.OK, "calljs init ready");
            //dataResult.setKeepCallback(true);// 非常重要
            //mCallbackContext.sendPluginResult(dataResult);
            return true;
        } else {
            return false;
        }
    }

    @Override
    public Object onMessage(String id, Object data) {
        return null;
    }

    public static void callJS(String message) {
        if (mCallbackContext != null) {
            PluginResult dataResult = new PluginResult(PluginResult.Status.OK, message);
            dataResult.setKeepCallback(true);// 非常重要
            mCallbackContext.sendPluginResult(dataResult);

PluginName.callJS("myinit()");
