Android phonegap上的skydrive应用程序

我们正在尝试使用phonegap访问skydrive。我们使用活动调用skydrive的登录功能。但它根本不调用登录函数

如果有人能说明这一点，那将是很大的帮助

这是代码

这里的活动是从phonegap的插件类调用的

下面的代码是被调用的活动

此处显示活动，但不显示登录页面，该页面应显示为登录功能的结果

Intent i = new Intent(myac, DispAct.class);
try{
                    System.out.println("before start activity");
                     //i.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
                    // i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                ( this.cordova.getActivity()).startActivity(i);
}
catch(Exception e){  System.out.println("in catch"+e);}
