I installed Android Studio 4.1 and tried to run the existing project. But it gives an error like this:
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
You have to set the JAVA_HOME Environment Variable.
On Windows, I solved the issue as follows:
Download the Java JDK from here and install it. (This links to version 15, which requires you to create an account in order to download. Version 16 is available to download without creating an account, but it has caused me an error that required me to downgrade.)
Set the "JAVA_HOME" Environment Variable:
Open Windows Search, type in “env”, and choose “Edit the system environment variables”.
Click on "Environment Variables...".
Click on "New".
Fill in the "variable name" field with "JAVA_HOME".
Fill in the "variable value" with the path to where Java is installed on your computer. (for me it was under "C:\Program Files\Java\<jdkversion>".)
Click "OK" and close all dialogs.
Restart your IDE / Terminal. (do not skip this step)
On Ubuntu 20.04 with Android 4.1, this error can be solved using the Snap version with:
flutter config --android-studio-dir=/snap/android-studio/current/android-studio
For Windows :
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
This command works fine if you have Android Studio installed. Flutter can understand the configurations of the Android Studio and you don't have to provide JAVA_HOME anymore.
Edit (Bonus) :
Also, download "Android SDK Command-line Tools" in android studio for android-licenses. Steps are shown in the image below.
You need to install Java JDK software which is required for the android studio.
sudo apt install openjdk-11-jdk
UPDATE: run flutter upgrade to upgrade to Flutter 1.22.2, which fixes compatibility issues with Android Studio 4.1. See related Flutter release.
This issue has been resolved v
See this issue regarding Android Studio 4.1 and Flutter
You can either downgrade back to Android Studio 4.0.2 or you can
install the latest JDK and update your JAVA_HOME variable and
PATH (OS dependent).
Note that if you choose to continue using 4.1 instead of downgrading,
flutter doctor will tell you Android Studio is not installed.
You need to run flutter config --android-studio-dir='<path to android studio>' in order to fix this issue. flutter doctor will now also
incorrectly report that the Flutter and Dart plugins are not
installed even if they are - you can ignore this.
Install Android Studio (skip this step if you already installed)
Goto
C:\Program Files\Android\Android Studio\jre and copy the path.
Make New variable called "JAVA_HOME". And paste above path as the variable value.
I set my JAVA HOME to the path,
/snap/android-studio/97/android-studio/jre/
Then I set my android studio config in flutter by using this command:
flutter config --android-studio-dir=/snap/android-studio/current/android-studio
My system is :
Ubuntu 20.04 with Flutter plugin version as 4.1,
In Mac:
In your terminal run
ECHO $JAVA_HOME
This will bring up the current path of java home.Pay close attention to the path that the terminal outputs.In my case i had System/Library instead of /Library/.../... typo as my path.So i simply corrected this in bash_profile.
If your path is correct but the error persists,
Right Click On Finder
Go To Folder
Bash_Profile
Add or Edit the Java Home Path
The path you add here should be the one your terminal output when you ran Echo $Java_Home..As long as this path that was echoed was/is correct..the below steps should fix the issue.
Then open your zshrc in a similar manner as you did with bash_profile and add the home path to the file.
You can also edit the bash_profile and zshrc files in your text editor.These files can be displayed using cmd + shift + . in your home folder.
After that,save,exit the terminal, close android studio and restart your machine.
Read this Article to learn more.
Locate where your Android Studio is installed.
For me C:\Program Files\Android\Android Studio
Check if the jre folder exists, Create a new folder called jre
Copy the contents of the jbr folder and paste them into the jre folder.
Check by running flutter doctor, and Restart IDE.
Thanks: roufy235 {cause}
For ubuntu 20.04 this solution will be appropriate: -
This link solved my problem. In short I would recommend to follow the simple steps, i.e.
Upgrade the flutter using flutter upgrade
Set the path of the flutter flutter config --android-studio-dir="/path/to/android/studio/"
Set the path in bashrc file by opening bashrc file(it is a hidden file)
export JAVA_HOME="/path/to/android/studio/jre/"
choco install javaruntime
If you use choco package manager. It will set the vars automatically.
This issue can also be caused if you have updated your Android Studio.
In that case.
For Windows
First Open the Users\username\AppData\Local\Google directory on your PC/Laptop and make sure to Delete the older version of your Android Studio.
e.g, Current version of Android studio is Electric Eel (2022.1).
Delete any other older version from that directory accordingly and restart your PC or Laptop.
Then try running your project.
Install openjdk-8 ....
You have to restart your terminal, the issue will persist even after download if you don't restart the terminal.
Follow react native guide to download openjdk for your environment. ...
https://reactnative.dev/docs/environment-setup
For Windows this worked
Go to C:\Program Files\Android\Android Studio.
Copy all the files inside of jbr directory.
Paste all the files into jre directory.
Then run flutter doctor. The issue will go away.

Download Liberica JDK and on installation it will automatically set JAVA_HOME environment variable.
Now you just go to Android Studio -> Project Structure -> SDK -> Point all jdk path to liberica jdk installation directory and apply.
You are done. Just restart android studio and gradle command will work.

Some other questions suggest playing with symlinks in the jre folder in the Android Studio install, but I have no jre folder in there. There is however a jbr folder, which appears to contain an OpenJDK build. But I don't know how to get flutter to see/use it.

Installed all the components as required in the documentation. I think I've set environment and other parts up correctly.
UPDATE 2
While the suggestion in Update 1 would work, this is not a "script" interpreted in real-time, and rather part of the flutter binary (if I am not mistaken), so in order for this to work, one would have to compile the flutter binary again, I don't know how to do that right now (as I've never used flutter beyond the basics) and I can't certainly do it on my "work machine" where the Corporate eyes forbid everything that is fun.
In other words, use the symlink trick you found in this GitHub issue until the Flutter team releases an updated flutter that searches for the correct java Path in the newer versions of Android Studio.
And Jetbrains, please, stop renaming the java location every other year...
UPDATE 1
In the flutter sdk, there's a file called: android_studio.dart. (well there are various android related files, none "java" related, since it seems like Flutter treats Java as an "android thing" (judging by the fact that all java references and validations or checks are performed in android_ files).
This file is located in path/to/flutter/packages/flutter_tools/lib/src/android/android_studio.dart.
Inside it contains this to calculate the path to java:
final String javaPath = globals.platform.isMacOS ?
version != null && version.major < 2020 ?
globals.fs.path.join(directory, 'jre', 'jdk', 'Contents', 'Home') :
globals.fs.path.join(directory, 'jre', 'Contents', 'Home') :
globals.fs.path.join(directory, 'jre');
In essence, if you add another entry like this:
globals.fs.path.join(directory, 'jbr', 'Contents', 'Home') :
So it ends up looking like:
final String javaPath = globals.platform.isMacOS ?
version != null && version.major < 2020 ?
globals.fs.path.join(directory, 'jre', 'jdk', 'Contents', 'Home') :
globals.fs.path.join(directory, 'jre', 'Contents', 'Home') :
globals.fs.path.join(directory, 'jbr', 'Contents', 'Home') :
globals.fs.path.join(directory, 'jre');
Then you can run flutter doctor and it may work.
I also removed the && version.major < 2020 part, just to ensure it was always run. Now I see:
[!] Android Studio (version 2022.1)
✗ Unable to find bundled Java version.
[✓] Android Studio (version 2021.3)
So... Two different Android Studio versions, the latest (the one with jbr instead of jre seems to work fine.
In Android Studio Electric Eel, the bundled Java was moved to /Applications/Android Studio.app/Contents/jbr/Contents/Home so you can set your $JAVA_HOME to point to that directly.
In Addition, if you're on macOS (as it looks like that's the case) remember macOS uses (for some Apple reason) a binary called java_home to set the JAVA installations.
You can find this binary in /usr/libexec/java_home.
It seems like the flutter plug-in may be looking for Java under the assumption that it's under the "old" jre instead of the "new" jbr folder. I don't know if this is hardcoded (and therefore needs a 'patch') or if it just reads the environment variable for JAVA_HOME.
Are you using Jetbrain Toolbox to manage Android Studio?
If so, my solution may work for you.
I'm also using M1Air, Flutter 3.7.0, Android Studio Electric Eel 2022.1.1
cd ~/Library/Application\ Support/JetBrains/Toolbox/apps/AndroidStudio/ch-0/{ YOUR_VERSION_OF_ANDROID_STUDIO }/Android\ Studio.app/Contents/
run ls and look for /jbr
run sudo ln -s jbr jre and flutter doctor
This solved my problem.
EDIT
Your version of Android Studio can be found at Jetbrain Toolbox -> Android Studio -> Settings(3 dots on the right) -> Configuration -> Install Location

I've tried adding a JAVA_HOME kind of solution but didn't work for me.
I had that problem today after updating Android Studio, and found an answer here:
https://github.com/flutter/flutter/issues/118502
The solution is basically:
Go to your AndroidStudio folder (normally C:\Program Files\Android\Android Studio in Windows)
Copy the content of jbr and paste the content into jre folder
Quick workaround from here: https://github.com/flutter/flutter/issues/118502#issuecomment-1384954269
Run in the terminal:
cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre

Open the folder where Android Studio is installed.
In most cases, it is "C:\Program Files\Android\Android Studio"
Open the "jbr" folder inside the Android Studio folder ("C:\Program Files\Android\Android Studio\jbr"), and copy all contents in it.
Then go back and create a new folder called "jre" -> "C:\Program Files\Android\Android Studio\jre"
Paste all contents which you copied from "jbr" folder to "jre" folder.
Click Start and search for "Environment" and open "Edit the Environment variables" from search result.
Click to open "Environment variables"
On "User variables" pane click new and add new variable with name "JAVA_HOME" and path "C:\Program Files\Android\Android Studio\jre". Click OK to save.
Restart Android Studio and run flutter doctor. It will solve the problem.

I do not plan on developing for the web, so didn't bother to download chrome as I don't use it as my browser.
Any ideas on why this is happening?
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:

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
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.
