调用系统通讯录选择手机号 Android插件

plus.contacts加载全部联系人，只为选择一个联系人时，联系人较多情况下，速度很慢。搞了个插件来调用系统通讯录，只返回选择的一个联系人。

使用：

plus.nativecontact.pick(function(contact){//成功  
           alert(contact.numbers[0].value);//所选择联系人的第一个电话号码  
    }, function(status){//失败  

    });  
//contact为联系人json对象，形式：{"givenName":"张三","numbers":[{"value":"123"},{"value":"456"}]}

添加权限：

"nativecontact":{  
            "description": "系统通讯录"  
        }

plugin.js：

document.addEventListener("plusready",  function()  
{  
    var B = window.plus.bridge;  
    var nativecontact =   
    {  
        "pick":function(successCallback, errorCallback){  
            var success = typeof successCallback !== 'function' ? null : function(args) {  
                        successCallback(args);  
                    },  
                fail = typeof errorCallback !== 'function' ? null : function(code) {  
                        errorCallback(code);  
                    },  
                callbackID = B.callbackId(success, fail);  
            return B.exec("nativecontact", "pick", [callbackID]);  
        }  
    };  
    window.plus.nativecontact = nativecontact;  
}, true);
