Can't download sdk 26 (android 8.0)

Hi !

I am creating an application in Kotlin that allows people to return at home in security after a party for exemple. One option for the application is to transfer a contact by nfc between two devices.
I would like to use nfc but some functions are deprecated, so I would like to download sdk26 (android 8.0 Oreo) but I can’t.
When I try to download sdk 26 on Android studio , I have this message :

Failed packages:

  • Intel x86 Atom System Image (system-images;android-26;default;x86)
  • Google APIs Intel x86_64 Atom System Image (system-images;android-26;google_apis;x86_64)
  • Google APIs Intel x86 Atom System Image (system-images;android-26;google_apis;x86)

  • Android TV Intel x86 Atom System Image (system-images;android-26;android-tv;x86)

! Requested actions did not complete successfully. See the IDE log for details

So I try on terminal with this command :

cd ~/Library/Android/sdk

./tools/bin/sdkmanager “platforms;android-26”

but I have this errors :

Exception in thread “main” java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema

… 5 more

If someone have an idea , it will be great !

Thank you community !
