The devices selector is stuck on "Loading Devices" and it stays like that.

[AbdulSamadgithub]

<----Problem----->
I've just started learning flutter and im setting up my device to run my app. Ive setup the emulator and the device as my instructor says. but it do not detect it. It detects the emulator and my mobile device on android project, but not on flutter.

Flutter doctor says "unable to locate android sdk" ive set the correct path to android sdk, ive double checked it. Ive installed both plugins dart and flutter.

I tried this solution :
Link : #4761
and updated the plugin. restarted the adb, restarted my computer. unplugged my device several times. restarted android studio and than adb several times. used 1.17.3 version of flutter to check, and nothing works.

I tried this too:
Link : https://stackoverflow.com/questions/51101178/android-studio-device-list-stuck-on-loading
started android studio as admin, and ive my sdk in my D: directory.

Please help. I'll be grateful.

Use this on the command line to tell Flutter where your Android SDK is located:
flutter config --android-sdk <path>

Use this to ensure all Android licenses have been accepted:
flutter doctor --android-licenses

Your Android Studio should be upgraded to 4.1.1 and version 52 of the Flutter plugin. Let us know if this helps.

I did as you said. even after updating them flutter doctor says flutter and dart plugins are missing.
my flutter plugin version : 52.0.1.
i've 4.1.1 version of android studio.

this exceptions occured with jdk15 with jdk 8 it is working correct. idk why.
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

im using jdk 8. I want to use the latest version of jdk.

[stevemessick]

Android Studio includes its own Java JDK. Don't try to use a different one.

Make sure the <path> given to flutter config --android-sdk points to you Android SDK, not a Java JDK.

Consult your instructor for further installation help.

Encountered this bug with latest release of flutter & studio

exactly the same issue

update: the problem went away after using this advice #5031 (comment)

I got this...
My Project Structure->Project settings-> project->Project SDK setting is empty.
When I select one android sdk, loading devices option was gone.
