title: Signed apk failed with error FileUsesReservedNameException
body: <p>my app runs fine and I can build apk with no error but when I try to build signed apk it fails with this error message:
  Execution failed for task ':startHulyoMainActivity:packageReleaseBundle'.</p>
  
  <blockquote>
    <p>java.util.concurrent.ExecutionException: com.android.tools.build.bundletool.exceptions.BundleFileTypesException$FileUsesReservedNameException: File 'root/res/drawable-xhdpi/zooz_cards_unionpay_l.png' uses reserved file or directory name 'res'.</p>
  </blockquote>
  
  <p>I am using this JAR: zooz-ecomm-android-sdk-1.02.jar</p>
  
  <p>How can I fix it and build the signed apk?</p>
