Neat function to bind ViewModels on android

StartRecordingActivity.kt

class StartRecordingActivity : ToolbarActivity() {

  private val startRecordingViewModel: StartRecordingViewModel by bindViewModel(this, StartRecordingViewModel::class)
 
   override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
      /* your ui code */
    }
 }
 
// put this in utils somewhere
fun <T : ViewModel, S : FragmentActivity> bindViewModel(to: S, modelClass: KClass<T>) = lazy {
  ViewModelProviders.of(to).get(modelClass.java)
}
