Question

初始化Geofence引发未捕获的错误“未找到类”

已经尝试：

1. 删除/添加Android平台
2. 平台准备就绪后使用]
3. 在设备和模拟器上安装了Google Play服务
4. Liveload工作指定错误，但在安装cordova-plugin-geofence后构建android无法工作

我在安装时收到此消息

在使用应用程序版本插件的情况下，我的应用程序Ionic4中遇到Class Not Found错误，因为我正在使用livereload功能测试我的应用程序。我们应该只要在应用程序中安装了新插件，就应该再次构建应用程序，特别是在进行livereload时
