myapp



app.initialize（）；
//听者问我，你的手机是什么
//
文件。添加的监听器（“deviceready”，OnDeviceraddy，false）；
函数ondevicerady（）{
试一试{
检查连接（）；
}
捕获（e）{
控制台日志（e）；
}
}
函数checkConnection（）{
var networkState=navigator.connection.type；
变量状态={}；
状态[Connection.UNKNOWN]=“connexion de type INCONU'；
状态[Connection.ETHERNET]=“连接以太网”；
状态[Connection.WIFI]=“连接WIFI”；
状态[Connection.CELL_2G]=“connexion 2G”；
状态[Connection.CELL_3G]=“connexion 3G”；
状态[Connection.CELL_4G]=“连接4G”；
states[Connection.CELL]='connexion generique'；
states[Connection.NONE]=“连接互联网”；
document.getElementById（'connexion'）.innerHTML='type de la connexion internet:'+状态[networkState]；
}

我花了一整天的时间来解决这个问题。我所做的是，用一个正在工作的旧项目中的相同文件替换NetworkManager.java。

现在，应用程序脱机时不会崩溃。

我也遇到了同样的问题，这为我解决了问题：

cordova plugin rm org.apache.cordova.network-information

cordova plugin add https://github.com/apache/cordova-plugin-network-information

这是一个插件问题。

快跑

cordova plugin rm org.apache.cordova.network-information
cordova plugin add https://github.com/apache/cordova-plugin-network-information

就像MazzCris建议的那样

欢迎来到StackOverflow（SO）！关于SO的问题用英语/J'ai traduit ta anglais，personne répondra sur une question en français；）您是否可以添加导致此问题的代码？谢谢。这似乎是个插件问题。安装当前插件版本（-dev版本）后，异常消失
