Android - The constructor ActionBarDrawerToggle is undefined

I used this code in my oncreate function to open the navigation drawer by pressing the app icon.

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                (DrawerLayout) findViewById(R.id.left_drawer), /* DrawerLayout object */
                getResources().getDrawable(R.drawable.ic_drawer),  /* nav drawer icon to replace 'Up' caret */
                getString(R.string.drawer_open),  /* "open drawer" description */
                getString(R.string.drawer_close)  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(R.string.title_activity_add);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(R.string.drawer_title);
            }
        };

Now it says "The constructor ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String) is undefined". I have imported android.support.v4.app.ActionBarDrawerToggle. Where's the problem?

Just to echo @CommonsWare answer. Instead of findViewById(R.id.left_drawer) just do R.id.left_drawer

So the final result would look like this:

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                R.drawable.ic_drawer,  /* nav drawer icon to replace 'Up' caret */
                R.string.drawer_open,  /* "open drawer" description */
                R.string.drawer_close  /* "close drawer" description */
                )

The constructor is not ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String). It is ActionBarDrawerToggle(Activity, DrawerLayout, int, int, int). Change your last three parameters to be the resource IDs, not the results of referencing the resource IDs.
