it doesn't let me save the R.string in R.java and it always says that i have modified even though i have not can someone please help me i have tried cleaning the project and it still dose not solve the issue.

public class MainActivity extends Activity {

private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;

private CharSequence mDrawerTitle;
private CharSequence mTitle;
CustomDrawerAdapter adapter;

List<DrawerItem> dataList;

@Override
protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      // Initialising
      dataList = new ArrayList<DrawerItem>();
      mTitle = mDrawerTitle = getTitle();
      mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
      mDrawerList = (ListView) findViewById(R.id.left_drawer);

      mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
                  GravityCompat.START);

      // Add Drawer Item to dataList
      dataList.add(new DrawerItem("Message", R.drawable.ic_action_email));
      dataList.add(new DrawerItem("Likes", R.drawable.ic_action_good));
      dataList.add(new DrawerItem("Games", R.drawable.ic_action_gamepad));
      dataList.add(new DrawerItem("Lables", R.drawable.ic_action_labels));
      dataList.add(new DrawerItem("Search", R.drawable.ic_action_search));
      dataList.add(new DrawerItem("Cloud", R.drawable.ic_action_cloud));
      dataList.add(new DrawerItem("Camara", R.drawable.ic_action_camera));
      dataList.add(new DrawerItem("Video", R.drawable.ic_action_video));
      dataList.add(new DrawerItem("Groups", R.drawable.ic_action_group));
      dataList.add(new DrawerItem("Import & Export",
                  R.drawable.ic_action_import_export));
      dataList.add(new DrawerItem("About", R.drawable.ic_action_about));
      dataList.add(new DrawerItem("Settings", R.drawable.ic_action_settings));
      dataList.add(new DrawerItem("Help", R.drawable.ic_action_help));

      adapter = new CustomDrawerAdapter(this, R.layout.custom_drawer_item,
                  dataList);

      mDrawerList.setAdapter(adapter);

      mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

      getActionBar().setDisplayHomeAsUpEnabled(true);
      getActionBar().setHomeButtonEnabled(true);

//

R.string.drawer_open and drawer_close is where the problem //is and the rest of the code is fine i believe

      mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,             
                  R.drawable.ic_drawer, R.string.drawer_open,
                  R.string.drawer_close) {
            public void onDrawerClosed(View view) {
                  getActionBar().setTitle(mTitle);
                  invalidateOptionsMenu(); // creates call to
                                                            // onPrepareOptionsMenu()
            }

            public void onDrawerOpened(View drawerView) {
                  getActionBar().setTitle(mDrawerTitle);
                  invalidateOptionsMenu(); // creates call to

            }
      };

      mDrawerLayout.setDrawerListener(mDrawerToggle);

I think that you cannot access resources in or before onCreate()
