Cannot resolve symbol DrawerLayout

Question

I'm trying to implement the Navigation Drawer as shown here: http://developer.android.com/training/implementing-navigation/nav-drawer.html#top

My code seems to be ok, and My minimum and target levels in my manifest match the example, but it's telling me it can't find the following three references

import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;

Answer 1

May be you have found your answer but i think its for those who still wants to know. so, here's my answer,

For Android Studio:

First of all you need to add External Jar

• In android studio go to File-> Project Structure -> Modules -> Dependencies -> + symbol -> Library Dependency.
• Now search for support library. you will find something like this com.android.support:support-v13
• Now, select Jar file named support-v13 (Whatever the version is) and click OK.

Now, you will see, no more errors like this.

For Eclipse:

Answer 2

You need to make sure you are using the latest support library as the DrawerLayout and other items were added in the May 2013 release.

• Added DrawerLayout for creating a Navigation Drawer that can be
  pulled in from the edge of a window.
