Android 许可证状态未知的 Flutter 错误

Question

I tried to run flutter on my Windows 10 and getting some errors. Trying to resolve error " Android license status unknown." from the last couple of hours. But no luck. My system environment is like the followings:

Windows 10, java version "12.0.2" 2019-07-16, Android Studio 3.5.

Can anyone know the thing which I am missing here?

I tried the following command ( flutter doctor --android-licenses ) and getting the errors like this:

C:\Users\me>flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
C:\Users\me\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

Answer 1

Did you already accepted the licenses? If not, try

flutter doctor --android-licenses

As shown in How to accept Android licenses

Answer 2

Actually The Android License is not necessary to do. Just open the android studio and start a new flutter project and have fun! If you want to do so. Type the command: flutter doctor --android-licenses Have Fun!

Answer 3

I solved it. I set JDK_HOME and then run the following command to fix:

flutter doctor --android-licenses

So, basically it was unable to configure JDK home and that error occurred. Hopefully, it will solve issues if you face this error.

Answer 4

Its worked me..

So here the solution, open your SDK manager then uncheck Hide Obsolete Packages

Now you'll see Android SDK Tools (Obsolete) 26.1.1 appears. Tick that package and hit apply button then ok button. it will download sdk. then restart Android studio

Nice, now if you run flutter doctor , you should get positive result as below

PS D:\Workplace\flutter_projects> flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.12.13+hotfix.8, on Microsoft Windows [Version 10.0.18363.657], locale en-MY)

[√] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
[√] Android Studio (version 3.6)
