Flutter.io Android License Status Unknown

We Are Going To Discuss About Flutter.io Android License Status Unknown. So lets Start this Java Article.

Flutter.io Android License Status Unknown

  1. Flutter.io Android License Status Unknown

    If you updated the android SDK, the licenses may have changed. Depending on how you did the update you may or may not have been prompted to accept the changes, or maybe it just doesn't save the fact that you did accept them in a way flutter can understand.

  2. Flutter.io Android License Status Unknown

    If you updated the android SDK, the licenses may have changed. Depending on how you did the update you may or may not have been prompted to accept the changes, or maybe it just doesn't save the fact that you did accept them in a way flutter can understand.

Solution 1

Just install the sdk command line tool(latest) the below in android studio.
enter image description here

Then run:
flutter doctor --android-licenses

After which you should get:

[email protected] ~ % flutter doctor --android-licenses
5 of 7 SDK package licenses not accepted. 100% Computing updates...             
Review licenses that have not been accepted (y/N)? y

…and then you’ll get a whole bunch of licenses to read whilst you sip your favourite beverage.

Solution 2

If you updated the android SDK, the licenses may have changed. Depending on how you did the update you may or may not have been prompted to accept the changes, or maybe it just doesn’t save the fact that you did accept them in a way flutter can understand.

To resolve, try running

flutter doctor --android-licenses

This should prompt you to accept licenses (it may ask you first, in case just type y and press enter – although it should tell you that).

If you still have problems after doing that, it might be worth either opening a new bug in the Flutter Github repository, or adding a comment on an existing issue like this one as it may be what you’re seeing.

Solution 3

The error:

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)
        at com.android.sdklib.tool.sdkmanager.SdkManagerCli.main(SdkManagerCli.java:48)
Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema

        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:499)
        ... 5 more

is occurring because the current SDK version is incompatible with Java 9.

So, to solve it, you can downgrade your java version to Java 8, or with a workaround, you can export the following option on your terminal:

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

And to make it stick, you can export the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add as an environment permanently on Windows.


Then, you can type the flutter or sdkmanager command:

Flutter:

flutter doctor --android-licenses

sdkmanager:

sdkmanager --licenses

and type Y when needed to accept the licenses.

ps. This doesn’t work for Java 11/11+, which doesn’t have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

Solution 4

The right solution would be if you have android studio installed then

  1. open SDK manager
  2. under SDK tools uncheck hide obsolete packages at the bottom
  3. then you should see an option called Android SDK Tools (Obsolete)

enter image description here

  1. check it and apply and let the studio download the package
  2. once done run the command flutter doctor and it should now prompt you to run flutter doctor --android-licenses
    once you run the license command accept all licenses by hitting y and it should solve the problem
