title: Android run time exception while using gestureImageView and ViewGroup
body: <p>Hi i am new to Android application. I want to add zooming effect to my image. I took a sample tutorial from [https://github.com/jasonpolites/gesture-imageview][1] and copied sample code from there. But when I was tried to run the java code in eclipse, an exception is raised. 
  Codes are attached here.</p>
  
  <p>ViewIndia.java</p>
  
  <pre><code>public class ViewIndia extends Activity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_view_india);
  
                  LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
  
                  GestureImageView view = new GestureImageView(this);
                  view.setImageResource(R.drawable.india);
                  view.setLayoutParams(params);
  
                  ViewGroup lout = (ViewGroup) findViewById(R.id.gestureImageView);
  
                  lout.addView(view);
              }
  
          @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.view_india, menu);
          return true;
      }
  
  }
  </code></pre>
  
  <p>activity_view_india.xml</p>
  
  <pre><code>&lt;RelativeLayout
