Android Dex : the “–core-library” option to suppress this error message

I’m trying to use SlidingMenu ( in IntelliJ Idea 12 https://github.com/jfeinstein10/SlidingMenu) Compile a simple Android project, but I’m running into this issue:
enter image description here

I only have this activity :

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setTitle("Test");
         set the content view
        setContentView(R.layout.main);
         configure the SlidingMenu
        SlidingMenu menu = new SlidingMenu(this);
        menu.setMode(SlidingMenu.LEFT);
        menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
        menu.setFadeDegree(0.35f);
        menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
        menu.setMenu(R.layout.menu);
    }
}

Solution

Include (turn on) FLAG in the IDE compilation settings (Android compiler):
Add the “–core-library” flag

Will solve this problem
