阅读短信收件箱在Android中不起作用？

Question

我正在使用cordova phonegap 2.1.0

我已下载代码： Phone Gap SMS Read Extension

然后我根据新的cordova库修改了代码

修改了Smsread.js

var SMSReader = function () {};

SMSReader.prototype.getInbox = function(params, success, fail) {
    return cordova.exec(function (args) {
    success(args);
}, function(args) {
    fail(args);
}, 'SMSReader', 'inbox', [params]);
};

SMSReader.prototype.getSent = function(params, success, fail) {
return cordova.exec(function (args) {
    success(args);
}, function(args) {
    fail(args);
}, 'SMSReader', 'sent', [params]);};
if (!window.plugins) {
window.plugins = {};
}
 if (!window.plugins.SMSReader) {
window.plugins.SMSReader = new SMSReader();
}
//cordova.addConstructor(function () {
//    cordova.addPlugin("SMSReader", new SMSReader());
//    PluginManager.addService("SMSReader", "com.example.sample2");
//});

修改了SMSReader.java

package com.example.sample2;

        }
    }
    else {
        result = new PluginResult(PluginResult.Status.INVALID_ACTION);
        Log.d("SMSReadPlugin", "Invalid action : "+action+" passed");

}

仍然无法得到结果。请帮助。
