How to replace deprecated android.support.v4.app.ActionBarDrawerToggle

Yesterday (17-10-2014) I have update Android SDK and

support-library-v4.jar
of my App, now I get deprecation warning related to
ActionBarDrawerToggle
, reading the documentation seems that I have to use the
ActionBarDrawerToggle
in
support-library-v7.appcompact.jar
.

Here some parts of my Activity that could be relevants:

import android.app.ActionBar;
import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.webkit.WebView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.TextView;


public class MyActivity extends FragmentActivity {
private ActionBar bar;
private CustomActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawer;
private ListView mDrawerList;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_infoviewer);

bar = this.getActionBar();

bar.setDisplayHomeAsUpEnabled(true);

bar.setHomeButtonEnabled(true);
bar.setDisplayShowTitleEnabled(false);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);

mDrawer.setBackgroundColor(getResources().getColor(R.color.White));
initNavMenu();
try {
mDrawerToggle = new CustomActionBarDrawerToggle(this, mDrawer);
} catch (RuntimeException e) {
e.printStackTrace();
}

mDrawer.setDrawerListener(mDrawerToggle);
}

....

private void initNavMenu() {
NavMenuAdapter mAdapter = MyDrawers.getDefaultDrawer(MyActivity.this, true);
mDrawerList = (ListView) findViewById(R.id.drawer);
mDrawerList.setBackgroundColor(getResources().getColor(R.color.GreenMoneyDark));
if (mDrawerList != null) mDrawerList.setAdapter(mAdapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener(MyActivity.this, mDrawer, mDrawerList));
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}

private class CustomActionBarDrawerToggle extends ActionBarDrawerToggle {

public CustomActionBarDrawerToggle(Activity mActivity,
DrawerLayout mDrawerLayout) {
super(mActivity, mDrawerLayout, R.drawable.action_drawer,
R.string.ns_menu_open, R.string.ns_menu_close);
}

@Override
public void onDrawerClosed(View view) {
bar.setTitle(getString(R.string.ns_menu_close));
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}

@Override
public void onDrawerOpened(View drawerView) {
bar.setTitle(getString(R.string.ns_menu_open));
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
}

}


I have tried to copy support-library-v7 and replace

import android.support.v4.app.ActionBarDrawerToggle;


with

import android.support.v7.app.ActionBarDrawerToggle;


this has caused compilation problem in

public CustomActionBarDrawerToggle(Activity mActivity,
DrawerLayout mDrawerLayout) {
super(mActivity, mDrawerLayout, R.drawable.action_drawer,
R.string.ns_menu_open, R.string.ns_menu_close);
}


So I have tried to replace
R.drawable.action_drawer
with

public CustomActionBarDrawerToggle(Activity mActivity,
DrawerLayout mDrawerLayout) {
super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
R.string.ns_menu_open, R.string.ns_menu_close);
}


this compiles but crash at Runtime with

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/appcompat/R$attr;
at android.support.v7.widget.Toolbar.<init>(Toolbar.java:190)
at android.support.v7.widget.Toolbar.<init>(Toolbar.java:186)


Note that
android-support-v7-appcompat.jar
is correctly added in project dependencies

Answer

Adding only android-support-v7-appcompat.jar to library dependencies is not enough, you have also to import in your project the module that you can find in your SDK at the path \android-sdk\extras\android\support\v7\appcompatand after that add module dependencies configuring the project structure in this way

enter image description here

otherwise are included only the class files of support library and the app is not able to load the other resources causing the error.

In addition as reVerse suggested replace this

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
                    R.string.ns_menu_open, R.string.ns_menu_close);
        }

with

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
        }
