<pre>

  public SpinnerActivityTest() {

    super("com.android.example.spinner", SpinnerActivity.class);

    super(SpinnerActivity.class);

  } // end of SpinnerActivityTest constructor definition

</pre>

<p>

  This calls the superclass constructor with the Android package name (<code>com.android.example.spinner</code>)and main activity's class

  (<code>SpinnerActivity.class</code>) for the application under test. Android uses this information to find the application and activity to test.
