title: Android Image button does not work.
body: <p>I am making a contact app and I have added an image button. When user clicked on the image button, he/she would be directed to the calling application. When I run the code on the emulator, the image button does not work. 
  Below is my code:</p>
  
  <pre><code>public void addListenerOnButton() {
  
      imageButton = (ImageButton) findViewById(R.id.imageButton1);
  
      imageButton.setOnClickListener(new OnClickListener() {
  
  
          @Override
          public void onClick(View v) {
              Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:12125551212"));
              startActivity(intent);
  
          }
  
      });
  
  }
  </code></pre>
  
  <p>The LogCat shows that eglSurfaceAttrib not implemented. Where did I get wrong?
  Any help will be appreciated. Thanking you.</p>
