  • On the installation steps, ran flutter doctor in powershell and it comes up with the following:

    I have jdk-16.0.1 installed. Not sure what to do

    @sbane256
    Check above comment and try with JDK 8 to see if it resolves your issue. If it does and running the command again gives you another error like Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema , then you'll need to install Android SDK Command-line tools from Android Studio with which you should be able to accept licenses.

  • Uninstalled JDK 16
  • Downloaded JDK 8 from https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
  • Made sure and tried to see the version on Powershell:

  • Ran flutter doctor and still getting the same issue (see below). Also already installed Android SDK command-line tools from Android Studio:

    -Tried exiting out and editing variables to include JAVA_HOME and the java/bin in the Path but that didn't help either.
    

    Any help?

    Hi @sbane256, sorry that the above didn't work, out of interest do you get the same error running this command?

    Hi @tnc1997, I ran the command & "$Env:ANDROID_SDK_ROOT\tools\bin\sdkmanager" --licenses --verbose and got the following:

    Terms and Conditions
    

    This is the Google TV Add-on for the Android Software Development Kit License Agreement.
    
There were various licenses agreements after this and I accepted all 7. For example:
    

    _6 of 7 SDK package licenses not accepted.
    
Review licenses that have not been accepted (y/N)? Y
    

    1/6: License android-googletv-license:_
    

    Finally got the message:
    

    Accept? (y/N): Y
All SDK package licenses accepted_
I then proceeded to run flutter doctor again cause I thought this would have worked, but it ran into the same issue. Is there a problem with not being able to locate java? Not sure...
Accept? (y/N): Y

    Hi @sbane256, apologies that didn't work, yeah it looks like an issue with Flutter & Java for some reason. Are there any additional details that you might be able to share by running flutter doctor --verbose? Here's my output for reference:

    Hi @sbane256  and everyone
    
First, make sure you've also installed cmd tools and then flutter doctor --android-licenses
    

    If the problem persists, I am not sure where I read it but this is likely a bug with this particular java version too
    

    C:\Users\Taha\Code\android-studio\jre\bin\java
    

    My Java path is set to default JDK that comes with Android Studio itself, which java 11, and there is no issue when executing flutter doctor --android-licenses
    

    [✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
    • Android SDK at C:\Users\Taha\Code\android-sdk
    • Platform android-30, build-tools 30.0.3
    • ANDROID_SDK_ROOT = C:\Users\Taha\Code\android-sdk
    • Java binary at: C:\Users\Taha\Code\android-studio\jre\bin\java
    • Java version OpenJDK Runtime Environment (build 11.0.8+10-b944.6842174)
    • All Android licenses accepted.
    

    Hope this helps

    i do have same issue that why i installed the java 8 from oracle and set  JAVA_HOME  but i ran below issue
    

    C:\Windows\system32>flutter doctor --android-licenses
ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_29
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

    Then i follow the #84325 (comment) and install Android SDK Command line tools. After that i run flutter doctor --android-licenses , still throw java_home error then i removed environment variable JAVA_HOME  then i restart my system and run flutter doctor --android-licenses then it works.
    
Conclusion : No need to setup external jdk 8  or any version.
    

    Thanks TahaTesser and other
