Android license status unknown and a weird problem

Steps to Reproduce

I am running flutter in windows 10. I previously had a running android setup. After cloning the flutter repo and updating path, I ran flutter doctor -v. The logs are below. Now after searching a bit for solving the problem, I came across to this solution from various stackoverflow answers: Flutter.io Android License Status Unknown I at first executed this: set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee Though I don't know how to make it permanent. Then after running flutter doctor again, I came with another message, see log ###2

So it says Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses [!] Android Studio (version 3.4). So I ran flutter doctor --android-licenses accordingly. And it gives another error, that is: A newer version of the Android SDK is required. To update, run: C:\Users\imazi\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

Well, so I ran C:\Users\imazi\AppData\Local\Android\sdk\tools\bin\sdkmanager --update to update it. And it kinda updated successfully outputting [=======================================] 100% Computing updates...

So I thought the issue is solved and ran flutter doctor again but it seems that nothing has been changed the problem still remains. It is like a loop. I do everything and the problem remains as it is. The output of the last flutter doctor is in log ### 3

My java version is:

10.0.2 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)

Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

Please help.

!! also opened a github issue here: https://github.com/flutter/flutter/issues/39637

I had the same problem on windows, and solved by removing "\bin" from the JAVA_HOME value in system variables like this: "C:\Program Files\Java\jdk"

I uninstall the java jdk from my system and then let my flutter doctor arise that error of " [!] Android toolchain - develop for Android devices (Android SDK version 29.0.1)" and then followed the solution that flutter doctor was giving as it says to run the command " flutter doctor --android-licenses " and then type " y " as it says you to accept the licenses provided to solve this problem of "[!] Android toolchain - develop for Android devices (Android SDK version 29.0.1)" and then I again ran flutter doctor and the problem was resolved.

Actually, the problem got solved after installing jdk 8 and setting JAVA_HOME accordingly this new jdk. Also in the sdkmanager.bat file, located in C:\Users\username\AppData\Local\Android\Sdk\tools\bin I added the line set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_221"

No need to uninstall java 10. That solved the whole problem!

Check if the flutter path is added. Restart your system Then run flutter doctor --android-licenses accept all the licenses that appear again run flutter doctor and check if the issue persists
