I use the android.support library for my project, I have developed my app using android 4.4 and everything works good but my problem comes when I try to run the application in a device with Android Lollipop.
When it loads the Activity with the Toolbar, the application stops and returns this error.
Error inflating class android.support.v7.widget.Toolbar
I have found the same problem on the internet but I haven't found the solution in the answers.
This is my styles.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<!-- Base theme applied no matter what API -->
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/dark_primary</item>
<item name="colorAccent">@color/accent_color</item>
</style>
Here is my styles.xml (v22)
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Material.Light.NoActionBar">
<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/dark_primary</item>
<item name="colorAccent">@color/accent_color</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
</resources>
To define the toolbar in .xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mitoolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
tools:showIn="@layout/activity_main" />
And in my MainActivty I just include that toolbar:
<include layout="@layout/toolbar" />
And finally the header of my MainActivity.java
public class MainActivity extends android.support.v7.app.ActionBarActivity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //Here stops my application
}
Heres the logcat

Thank you in advance for your help.
The cause of the error is that, in the toolbar xml, the ?attr prefix refers to attributes in support library themes. On the other hand, under v22 of style.xml above, the system theme android:Theme.Material.Light.NoActionBar instead of a support library theme is used. The inflater therefore cannot resolve attributes of the support library such as ?attr/actionBarSize.
Using the support library theme Theme.AppCompat.Light.NoActionBar in style.xml (regardless of version) addresses the issue.
