SetShareIntent from the mainactivity is never used locally.. What does it mean?

Question

I have developed simple image app that is suppose to swipe the images from left to right .After reading this link http://developer.android.com/training/sharing/shareaction.html#set-share-intent . I implemented the codes in my mainActivity.java. This code is suppose to show sharing option at the top along the actionbar. However, I am getting little yellow lamp near this code ..private void setShareIntent(Intent shareIntent) {...What does it mean.. Following is my mainActivity.java code..

   import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ShareActionProvider;




public class MainActivity extends Activity {

    MediaPlayer oursong;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
      oursong = MediaPlayer.create(MainActivity.this, R.raw.a);
      oursong.start ();
    ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
    ImageAdapter adapter = new ImageAdapter(this);
    viewPager.setAdapter(adapter);
  }

  private ShareActionProvider mShareActionProvider;



  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate menu resource file.
      getMenuInflater().inflate(R.menu.activity_main, menu);

      // Locate MenuItem with ShareActionProvider
      MenuItem item = menu.findItem(R.id.menu_item_share);

      // Fetch and store ShareActionProvider
      mShareActionProvider = (ShareActionProvider) item.getActionProvider();

      // Return true to display menu
      return true;
  }



     @Override
     protected void onPause(){
     super.onPause();
      oursong.release();
 }

}

Answer 1

If there is only a "yellow lamp" icon beside that line, then it's just a warning. Your program will run smoothly regardless, but it simply states that the intent is not used anywhere in your program (it's placed there unnecessarily) so you should try removing that line. If your program still runs smoothly, you are done.
