title: Kotlin Android start new Activity
body: <p>I want to start another activity on Android but I get this error:</p>
  
  <blockquote>
    <p>Please specify constructor invocation; classifier 'Page2' does not have a companion object</p>
  </blockquote>
  
  <p>after instantiating the <code>Intent</code> class. What should I do to correct the error? My code:</p>
  
  <pre><code>class MainActivity : AppCompatActivity() {
  
      override fun onCreate(savedInstanceState: Bundle?) {
          super.onCreate(savedInstanceState)
          setContentView(R.layout.activity_main)
      }
  
      fun buTestUpdateText2 (view: View) {
          val changePage = Intent(this, Page2) 
          // Error: "Please specify constructor invocation; 
          // classifier 'Page2' does not have a companion object"
  
          startActivity(changePage)
      }
  
  }
  </code></pre>
