title: Changing image in ImageView on orientation change does not work
body: <p>I have activity with <em>android:configChanges="orientation|keyboardHidden"</em></p>
  
  <p>I am trying to change image in ImageView when the device orientation changes with:</p>
  
  <pre><code>public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
  
    // refresh the instructions image
    ImageView instructions = (ImageView) findViewById(R.id.img_instructions);
    instructions.setImageResource(R.drawable.img_instructions);
  }
  </code></pre>
  
  <p>This only works the first time when the phone is rotated but not after that.</p>
  
  <p>Can someone pls tell me why this happens?</p>
