ERROR: In <declare-styleable> FontFamilyFont Failed to execute aapt

hi, i have this error when installed and i trying run android,

  • @ionic-native/background-geolocation
  • cordova-plugin-mauron85-background-geolocation

i have ionic3,

*:processDebugResources
ERROR: In FontFamilyFont, unable to find attribute android:fontVariationSettings
ERROR: In FontFamilyFont, unable to find attribute android:ttcIndex

  • What went wrong:
    Execution failed for task ‘:processDebugResources’.

com.android.ide.common.process.ProcessException: Failed to execute aapt

any idea ??

What is your ionic info output?
Is ionic cordova requirements happy?

oh, im solved editig plugin.xml file from > background-geolocation change
framework src="com.android.support:support-+ to framework src=“com.android.support:support-v4:27.1.0”
and in project.properties too.

regards.
