If you use the Web fragment and other fragments in your activity, this code works:

In your Activity:

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.closeDrawer(GravityCompat.START);
    } else {
        // Webview back
        if (getSupportFragmentManager().findFragmentById(R.id.fragment_content) instanceof YourWebFragment){
            final YourWebFragment webFragment = (YourWebFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_content);
            if (webFragment != null){
                if (webFragment.onBackPressed()){
                    return;
                }
            }
        }
        // Fragments back
        if (getSupportFragmentManager().getBackStackEntryCount() > 0) {
            getSupportFragmentManager().popBackStack();
        } else {
            super.onBackPressed();
        }
    }
}

In your Web Fragment:

public boolean onBackPressed() {
    if (webView.canGoBack()) {
        webView.goBack();
        return true;
    }
    return false;
}
