Nativescript doctor throws warnings and errors - nativescript

Question

I want to connect my virtual android device to nativescript sidekick.
When I open NativeScript Sidekick and click on "Virtual Device Launcher" Button, I get the following error message.
[20-03-24 09:50:23.966] Unable to execute avdmanager, ensure JAVA_HOME is set and points to correct directory
So I ran tns doctor:

There seem to be issues with your configuration.
Component nativescript has 6.5.0 version and is up to date.

Your environment is not configured properly and you will not be able to execute local builds. To continue, choose one of the following options:
Run $ tns preview command to enjoy NativeScript without any local setup.
Run $ tns setup command to run the setup script to try to automatically configure your environment for local builds.
In order to test your application use the $ tns login command to log in with your account and then $ tns cloud build command to build your app in the cloud.
Verify that your environment is configured according to the system requirements described at http://docs.nativescript.org/setup/ns-cli-setup/ns-setup-win.html#system-requirements.
Android Studio Says Android SDK-Tools are installed:
ANDROID_SDK_HOME is in my environment variables (user):
JAVA_HOME is in my environment variables (system):
When I open cmd and run javac -version I get javac 1.8.0_131
adb devices says List of devices attached (works fine)

Answer 1

First option I suggest to you is to run sdkmanager in the command line and try tns run again.
For setting the java_home path this is a link : Setting JAVA_HOME at Android SDK
Second option you may need to change the path of ANDROID_HOME: for example this is mine
C:\Users\USERNAME\AppData\Local\Android\Sdk note the sdk at the end of the path
