So, I tried to add v7 appcompat support library with resource to MyFirstApp project, by following the tutorial @
http://developer.android.com/tools/support-library/setup.html
Both android-support-v4.jar and android-support-v7-appcompat.jar files were exported. Eclipse includes the android-support-v4.jar by default and when I tried the code:
// MainActivity.java
import android.support.v7.app.ActionBarActivity;// error
public class MainActivity extends ActionBarActivity {...} // error
// DisplayMessageActivity.java
import android.support.v4.app.NavUtils; // error on this line
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.display_message, menu);// error at R
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For
// more details, see the Navigation pattern on Android Design:
//
// http://developer.android.com/design/patterns/navigation.html#up-vs-back
//
NavUtils.navigateUpFromSameTask(this);// error at NavUtils
return true;
}
return super.onOptionsItemSelected(item);
}
I got a number of errors:

When I added the library android-support-v7-appcompat to MyFirstApp, and apply, I got the following errors:
