Android resource linking failed

[SylvainK200]

I have this issue when going through the readme of the project
`
A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction

Android resource linking failed
ERROR:/home/kouemo/.gradle/caches/transforms-3/ea3650f8c9f34660f6e65850d0bb6e3c/transformed/jetified-ussd-library-1.4.a/res/menu/menu_activity.xml:11: AAPT: error: attribute showAsAction (aka com.example.testussdnative:showAsAction) not found.`

Please do you know how to solve it ?
