deployment.AsyncDevicesGetter - adb not found

Question

I installed Android Studio 4.0. Added Flutter plugin. Installed Flutter already. Flutter doctor also showed everything is running well.

> C:\Users\Alvin>flutter doctor 
> Doctor summary (to see all details, run flutter doctor -v): 
> [√] Flutter (Channel beta, 1.19.0-4.1.pre, on Microsoft Windows [Version 10.0.18363.900], locale en-US)
> [√] Android toolchain - develop for Android devices (Android SDK version 30.0.0) 
> [√] Android Studio (version 4.0) [√] VS Code (version 1.45.1) 
> [√] Connected device (1 available)
> 
> • No issues found!

But when I open AVD Manager and launch the AVD in the emulator. I also got a pop-up

But actually the adb is installed already in C:\Users\Alvin\AppData\Local\Android\Sdk\platform-tools. So I add the path into the environment variable PATH to include this directory. And I can call the adb from anywhere in the command prompt.

But the same "Unable to locate adb still pop up every time I launch AVD. Actually, if I generate a simple Flutter program and run it in a mobile connected to the USB, it work in the mobile device.

Based on curiosity, I try to figure out what is actually happening. I opened the log file idea.log (open using Help -> Show log in explorer). I found out that the system actually trying to find ANDROID_HOME and ANDROID_SDK_ROOT. After I set them up, the Android Studio seems to be running well but there is a message that is still annoying. .deployment.AsyncDevicesGetter - adb not found Even though it is INFO only, I suspect this is the same problem when launching AVD Manager. the list of the log is as follows

Are there any information that can be shared about what I am facing and how to fix it? Additional information: adb version : 30.0.3-6597393 java version: 1.8.0_121

Answer 1

I also had the problem. A reinstallation did not solve the problem. I found the faulty ZIP file in the log file. It was gradle-6.1.1-all.zip, the download is from https://services.gradle.org/distributions/. It had to be replaced in C: \ Users \ xxxYourNamexxx \ .gradle \ wrapper \ dists \ gradle-6.1.1-all \ cfmwm155h49vnt3hynmlrsdst I replaced it and then it worked.

Answer 2

After spending days on this issue and didn't get any responses from Stackoverflow. I try a different approach. I uninstalled the Android Studio 4.0 completely including the Android SDK. Then I installed Android Studio 3.4. Setup Android SDK not in C:\Users{name}\android... But create my own folder for the Android SDK. Installed it. Then setup ANDROID_HOME, ANDROID_SDK_HOME in environment variables. Put the ANDROID_HOME in the path list. Then start the Android Studio. ADB work, everything works properly. After a while, I click the upgrade prompt to upgrade to Android Studio 4.0. Everything works properly. Then I installed the flutter plugin. Now everything works perfectly. But I still don't know why I got the problem in the first place. I just know by reinstalling, everything works perfectly now.
