AAPT: error: resource android:attr/lStar not found.

Whenever I package the game to android this error occurs

UATHelper: Packaging (Android (ETC2)): C:\Users\O.gradle\caches\transforms-2\files-2.1\db59709fd9d4cb349176afaa7521632c\core-1.8.0\res\values\values.xml:104:5-113:25: AAPT: error: resource android:attr/lStar not found.

Hello,
Did you find a way of solving this?
