Add fontawesome icons in my toolbar items menu

I'm trying to add Font Awesome library to my android project but i just can't. I was reading each google result about this topic.
My menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/buzon"
android:icon="#drawable/ic_buzon"
android:title="#string/buzon" />
<item
android:id="#+id/objetivos"
android:icon="#drawable/ic_objetivos"
android:title="#string/objetivos" />
<item
android:id="#+id/home_action"
android:icon="#drawable/ic_go_home"
android:title="#string/title_home" />
<item
android:id="#+id/encuesta"
android:icon="#drawable/ic_encuesta"
android:title="#string/encuesta" />
<item
android:id="#+id/cursos"
android:icon="#drawable/ic_cursos"
android:title="#string/cursos" />
</menu>
I'm want to use Font Awesome icons in my items menu instead default android icons.
For references, i was trying to follow this guide without success.

How to achieve a ripple animation by clicking on a menu item?

I have a toolbar
There is a overflow that displays options in menu
On click of menu item, How to achieve a ripple animation
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menuEventsTodayId"
android:title="#string/menu_events_today" />
<item android:id="#+id/menuUpcomingEventsId"
android:title="#string/menu_upcoming_events" />
<item android:id="#+id/menuSignOutId"
android:title="#string/menu_sign_out" />
</menu>
I tried with:
<item android:id="#+id/menuEventsTodayId"
android:background="?attr/actionBarItemBackground"
android:title="#string/menu_events_today" />
Its not working, How to properly achieve it

Just add the background as ?attr/selectableItemBackground. It will automatically give ripple on Android 5+

You can use following for android version above lollipop:
android:foreground="?attr/selectableItemBackground"
for prelollipop devices, you can use following:
compile 'com.balysv:material-ripple:1.0.2'

You need to define a separate style for your toolbar in the 'values' folder then add the following items to it:
<item name="selectableItemBackground">?android:selectableItemBackground</item>
<item name="android:colorControlHighlight">#color/ripple_material_dark</item>
Note:- As you can check this Link. ?android:selectableItemBackground is only properties which makes this animation.

i can't add the menu icons to the tool bar in visual studio xamarin

it seems that what ever i did i cant set the icons visible to the tool bar, i've tried to do researches on many platforms, but nothing helped.
here is the xml menu:
<?xml version="1.0" encoding="utf-8" ?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/event_ic"
android:icon="#mipmap/ic_event"
android:title="profile"
android:showAsAction="always"
/>
<item
android:id="#+id/details_menu"
android:title="details"
android:showAsAction="never"/>
</menu>
you can see that even if i set the android:showAsAction to always, i still get the event item in the pop up menu without the icon.

Why do I need to use app namespace in menu items when using AppCompat

Previously, before using AppCompat, I was using SherlockActionBar to support Android 2.3.
The following menu works just perfect under SherlockActionBar
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/menu_browser"
android:title="#string/menu_browser"
android:showAsAction="ifRoom"
android:icon="?attr/actionBarBrowserIcon"/>
<item
android:id="#+id/menu_share"
android:title="#string/menu_share"
android:showAsAction="ifRoom"
android:icon="?attr/actionBarShareIcon"/>
</menu>
However, even since migrating to AppCompat, I realize the above menu doesn't work. I need to use app namespace, in order to make it work.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/menu_browser"
android:title="#string/menu_browser"
app:showAsAction="ifRoom"
android:icon="?attr/actionBarBrowserIcon"/>
<item
android:id="#+id/menu_share"
android:title="#string/menu_share"
app:showAsAction="ifRoom"
android:icon="?attr/actionBarShareIcon"/>
</menu>
Why is this so? What is the difference comparing to SherlockActionBar, which makes app namespace unnecessary?

Attributes provided by libraries (or by the app itself) are suppose to be namespaced in order to avoid conflicts/collisions.
ActionBarSherlock masks this behavior by naming the attribute android:showAsAction. (As opposed to a showAsAction attribute in the android namespace): https://github.com/JakeWharton/ActionBarSherlock/blob/master/actionbarsherlock/res/values/abs__attrs.xml

ActionBar menuitems doesnt work using support library

my menu layout looks like this
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:blabla="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/msg_action_sections"
android:title="Sections view"
android:orderInCategory="100"
blabla:showAsAction="never" />
<item android:id="#+id/action_search"
android:title="Search"
blabla:showAsAction="collapseActionView"
blabla:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
but eclipse keeps giving me this error : "Should use android:showAsAction when not using the appcompat
library"
I don't know how to tell Eclipse that I'm using it!!! In android studio it worked, but I can't use Android studio. So what should I do?
Thank you
PS: Im using support.v7.app.ActionBar and my Activity extends from ActionBarActivity

Ok I figured it out, problem is, that I had bad theme using in AndroidManifest. You have to use Theme which uses Appcompat as parrent:)
