Java AndroidManifest error

I'm writing a Android plugin in Java for Unity and in my AndroidManifest.xml file i encountered these errors:

Error: String types not allowed (at 'configChanges' with value 'fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen') line 13 Android AAPT Problem

 <activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity" android:label="@string/app_name" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:screenOrientation="portrait">
       <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>

Thank you in advance.
