java.lang.NoSuchFieldError: android.support.v7.appcompat

I updated my support library from r20 to r21, now when I run my app I get this error in super.onCreate of my main activity : 

java.lang.NoSuchFieldError: android.support.v7.appcompat.R$styleable.Theme_windowActionBar
    at android.support.v7.app.ActionBarActivityDelegate.onCreate(ActionBarActivityDelegate.java:145)

my theme.xml :

<style name="AppBaseTheme" parent="Theme.AppCompat">
</style>

<style name="AppTheme" parent="AppBaseTheme">
    <item> ... </item>
</style>

in manifest :

android:theme="@style/AppTheme"

what is the problem ?

thanks

if you use intellij => you have to add in /project strutures/modules/ => YOURSDK\extras\android\support\v7\appcompat and add after in your project like that you have always the last support

I have compared support_v7_appcompat (version 20) with support_v7_appcompat (version 21). In res/values/attrs.xml (version 21), windowActionBar attributes are not in <declare-styleable name="Theme">

It happened same to me when I update SDK. If you have version 21 of library "Android Support Library" this bug occurs. I don't know what is the reason but last release make this bug.

You can solve it by downloading previous version of "Android Support Library" (r20) from here: https://dl-ssl.google.com/android/repository/support_r20.zip, and using it in your project.

You are welcome!
