Question

我正在使用NativeScript 1.7.0创建我的第一个应用程序（目前是android平台），我遇到了这个错误，当按某些页面上的后退按钮时会不时崩溃应用程序。我不确定这种情况的确切条件是什么。

之前还有其他人遇到过这个吗？任何想法为什么会发生这种情况以及如何解决或避免它？

NativeScript 1.7.0 tns-core-modules ^ 1.7.1 tns-android 1.7.1

以下是有关控制台中打印的异常的信息：

com.tns.NativeScriptException:

请确保您使用的是tns-core-modules和平台的Android 1.7.1或更高版本。 NS的几个版本有一些导航问题。我的理解是它们都应该在v1.7.1中解决

要升级;切换到主项目目录并执行以下每个简单命令：

npm install tns-core-modules @ latest -s
tns平台删除android
tns platform add android

然后你可以输入“cat package.json”或“type package.json”，你应该看到v1.7.1或更高版本的平台和核心模块。
