问题 According to Google's new Material Design guidelines, the navigation bar is supposed to be at the bottom. How can I implement it (if there is a way) ? For the moment, I'm using a Tabview which, by default on Android, is put at the top of the page. Thank you 回答1: For this case, i created a custom Nativescript component.

问题 I opened NativeScript Sidekick on my Mac and it updated to the latest version 0.2.5. It shows a dialog stating I need to update NativeScript CLI to 3.2.1 and the only option is to quit. I went to Terminal and tried tns update but it won't update to 3.2.1 saying the platforms for 3.2.1 are not available. (I posted to the NativeScript forums and was told that is correct -- the platforms are at 3.2.0 while only the CLI is updated to 3.2.1.) I also tried tns update 3.2.1 which simply says 3.2.1

问题 I would like a button. When you tap the button, the application closes, and go to home screen. Not needed to really close the app, just go to home screen.
