[SOLVED] Flutter Android licenses exception

01/12/2020 54 Comments

If you are here it means that you are facing a frustrating exception regarding Android licenses in Flutter.

More specifically the exception occurs when you try to run the following command:

$ flutter doctor --android-licenses

and the output is something like this:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)
at com.android.repository.api.SchemaModule.<init>(SchemaModule.java:75)
at com.android.sdklib.repository.AndroidSdkHandler.<clinit>(AndroidSdkHandler.java:81)
at com.android.sdklib.tool.sdkmanager.SdkManagerCli.main(SdkManagerCli.java:73)

Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema

... 5 more

The easiest fix I found is to install the Android SDK Command-line Tools.

In Android Studio open 

File > Settings > Appearance & Behavior > System Settings > Android SDK > SDK Tools

then tick the corresponding element, install and restart Android Studio and everything shoul work like a charm.

Happy coding!

  25. Hello there!

    A mobile developer beginner here.
    Please when you said “then tick the corresponding element” what were you referring to?

    Am I to tick all elements that are “Not Installed”?

    I’ll be glad to get a feedback from you.

    Thank you.

    1. Hello Emmanuel, as described here “The easiest fix I found is to install the Android SDK Command-line Tools.” you should select only the SDK command line tools 🙂
      Happy coding and enjoy Flutter!
