I get this error above when running flutter doctor --android-licenses. Does anyone know why this is happening and how I can fix it? I'm already running it on the flutter console.

Solution

  • Installing Android SDK Command-line tools from Android SDK Manager did the job for me.

    1. Open Tools > SDK Manager
    2. From the left choose, Appearance & Behavior > System Settings > Android SDK
    3. Select SDK Tools from the top menu
    4. Check Android SDK Command-line tools and click 'apply'.

    Alternative to step #1: WINDOWS: File > Settings (Ctrl+Alt+S) / MAC : Android Studio > Preferences

    This fix works for Windows, Linux and Mac OS X.

    If you are facing a problem in spite of the above steps, you can try upgrading your system to JDK 8. Official documentation of upgrading to JDK 8 is available here.
