title: dispatchPopulateAccessibilityEvent not triggered
body: <p>I'm trying to implement accessibility feature in my app. I'm confused about how it actually works. I've a simple imageView in different package from where I send events as:</p>
  
  <pre><code>public final void onClick(final android.view.View v) {
              android.util.Log.v(CLASSNAME,"onClick tag:"+v.getTag());
              v.sendAccessibilityEvent(android.view.accessibility.AccessibilityEvent.TYPE_VIEW_CLICKED);
  </code></pre>
  
  <p>I've implmented Accessibility class as follows:</p>
  
  <pre><code>import android.content.Context;
  
  public final class Accessibility extends android.view.View {
       public Accessibility(Context context) {
          super(context);
          // TODO Auto-generated constructor stub
      }
  
  
  
      public static android.view.accessibility.AccessibilityManager manager = (android.view.accessibility.AccessibilityManager)getSystemService(android.content.Context.ACCESSIBILITY_SERVICE); 
      public static android.view.accessibility.AccessibilityEvent event = android.view.accessibility.AccessibilityEvent.obtain();
  
      public static Accessibility accessibility;
  
  
      public static boolean isEenabled()
      {
  
      if(manager.isEnabled())
          return true;
      else
          return false;
      }
  
  
      @Override
      public boolean dispatchPopulateAccessibilityEvent(android.view.accessibility.AccessibilityEvent event)
      {
          super.dispatchPopulateAccessibilityEvent(event);
          android.util.Log.e(CLASSNAME, "Came here");
                          {
  
              event.getText().add("Click here!!");
              event.setEnabled(true);
                              return true;
          }
  </code></pre>
  
  <p>I read the Developer docs and I have to override the method in View class (that's the reason I extended my class to View). I realized this method also exists in Activity class (i.e. extends Activity) which calls this method without even sending any events.</p>
  
  <p>I know I'm doing something silly, but not able to find where exactly. </p>
  
  <p>P.S.: I did set a breakpoint on v.sendAccessibilityEvent - It goes to View.java and somehow it fails at condition "AccessibilityManager.getInstance(mContext)!= null"</p>
