Code:

eclipse points out this line as error : navDrawerToggle = new ActionBarDrawerToggle(MainActivity.this, navDrawerLayout, R.string.navdrawer_opened, R.string.navdrawer_closed)

private void setUpNavDrawer() {
    // TODO Auto-generated method stub
    navDrawerModel = new ArrayList<NavDrawerModell>();
    navDrawerModel.add(new NavDrawerModell(navDrawerIcons.getResourceId(0, -1), navDrawerOptions[0], ECO_ASSISTANT_DESC));
    navDrawerModel.add(new NavDrawerModell(navDrawerIcons.getResourceId(1, -1), navDrawerOptions[1], DATA_LOGGER_DESC));
    navDrawerModel.add(new NavDrawerModell(navDrawerIcons.getResourceId(2, -1), navDrawerOptions[2], ECO_ASSISTANT_DESC));
    navDrawerIcons.recycle(); // to recycle the typed array. never touch the typed array after this line.

    adapter = new NavDrawerListAdapter(getApplicationContext(), this.navDrawerModel);
    drawerListView.setAdapter(adapter);

    // enabling action bar app icon and behaving it as toggle button
    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    mTitle = mDrawerTitle = getTitle();

    navDrawerToggle = new ActionBarDrawerToggle(MainActivity.this, navDrawerLayout, R.string.navdrawer_opened, R.string.navdrawer_closed) {

        @Override
        public void onDrawerOpened(View drawerView) {
            // TODO Auto-generated method stub
            super.onDrawerOpened(drawerView);
            getActionBar().setTitle(mDrawerTitle);
            invalidateOptionsMenu(); // calling onPrepareOptionsMenu() to hide action bar icons
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            // TODO Auto-generated method stub
            super.onDrawerClosed(drawerView);
            getActionBar().setTitle(mTitle);
            invalidateOptionsMenu(); // calling onPrepareOptionsMenu() to show action bar icons
        }
    };
    navDrawerLayout.setDrawerListener(navDrawerToggle);
    drawerListView.setOnItemClickListener(new SlideMenuClickListener());

This is caused when there is a class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.
