Describe the bug
Until about 1-2 months ago i can use nativescript without problem, today i try to build an old project and i receive this error:

• Where:
  Build file '[cut]\platforms\android\app\build.gradle' line: 33

• What went wrong:
  A problem occurred evaluating project ':app'.

Plugin with id 'com.android.application' not found.

So i tried to build an "hello world" project and i receive the same error. What happened? In these 2 months i start to coding in Native Android Studio. Is possible i changed something?

Comienza con el fallo reportado en platforms/android/app/build.gradle en la línea 33 y, después, inspecciona las versiones de los componentes de NativeScript y Android mediante tns info o package.json. Reproduce el error tanto en el proyecto antiguo como en un proyecto nuevo de Hello World. Se considera terminado cuando la compilación de Android resuelve el application plugin y se completa correctamente.
