Answer 1

I have found out that this is because of the appid of the NativeScript. When I created the application using ns create myapp, I didn't specify --appid parameter. Hence NativeScript created one for me. However, you can change this id in ./nativescript.config.ts After you name with something unique to your app, it can start the emulator correctly.
