Android中onConfigurationChanged没调用

<span style="font-size:24px;"><activity
            android:name="com.example.second.MainActivity"
            android:label="@string/app_name" 
           <strong> android:configChanges="orientation|keyboard|<span style="color:#ff0000;">screenSize</span>"</strong>
            android:screenOrientation="portrait"
></span>

<pre name="code" class="java"><span style="font-size:24px;"><strong><span style="color:#ff0000;"></span></strong></span><pre name="code" class="java">一定要加上<span style="font-family: Arial, Helvetica, sans-serif;">screenSize这样才可以；当然权限也是要加的</span>

<span style="font-family: Arial, Helvetica, sans-serif;"><uses-permission 
        android:name="android.permission.CHANGE_CONFIGURATION"/>这样就可以了
</span>
