运行时异常Nativescript-Angular

Question

我是nativescript-angular的新手，虽然我因为一些开发的应用程序而表现出对Angular2的熟练程度。

我正在使用此sidedrawer，其中包含home，about和contact组件。

此外，我创建了一个搜索组件，负责接受用户输入并搜索搜索词的特定搜索引擎。

我在Android连接设备（Lollipop）上成功运行了我的nativescript应用程序但是我得到了：

1. D / AccessibilityManager（17308）：at com.tns.Runtime.callJSMethodNative（Native Method）
2. 当我导航到搜索组件时，搜索组件会停留几秒钟（比如2秒）并自行返回主页组件。

以下重点介绍我的配置

Android构建工具：25.0.0 打字稿：2.0.9 最新的nativescript模块 到目前为止我做了什么（删除并重新安装）：

node_modules 挂钩 平台android
