Missing bundled JRE in Android Studio for Flutter

Setting up Flutter on MacOS Ventura 13.2 on an M1 MacBook Air. I've installed everything to get [✓] except for flutter doctor unable to find a bundled jre in Android Studio. I have found some other questions on this site, but none helped.
alan#Alans-MacBook-Air ~ % flutter doctor

I have java installed:

I also have my environment setup correctly, I think:
alan#Alans-MacBook-Air ~ % echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
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.
alan#Alans-MacBook-Air ~ % /Applications/Android\ Studio.app/Contents/jbr/Contents/Home/bin/java -version

OpenJDK 64-Bit Server VM (build 11.0.15+0-b2043.56-8887301, mixed mode)
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

Flutter on IntelliJ building for Android cannot find `java`

Hitting a bit of a wall here when trying to build a brand new flutter sandbox application within IntelliJ for Android.
The error that I get is the following:
java: Cannot run program "/Users/vintrin/Library/AndroidStudio/sdk/bin/java" (in directory "/Users/vintrin/Library/Caches/JetBrains/IntelliJIdea2022.3/compile-server"): error=2, No such file or directory
This file /Users/vintrin/Library/AndroidStudio/sdk/bin/java in fact does NOT exist.
I am starting the IntelliJ from my terminal to get all the environment variables to be recognized by IntelliJ using

Below you can see the print out of the values from within the IntelliJ terminal:

How do I resolve java not being found?

Failing to launch my Flutter application on my android device [duplicate]

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.

flutter doctor --android-licenses shows error message

how to solve this error I show many video on it but that can not works.
I tried also JDK 8 but it doesn't works. Currently running on JDK 15.

have you tried running this?
flutter doctor --android-licenses

First, check if you have the older JDK version such as
JDK 1.8.0_301
Java SE Development Kit 8u202
Download JDKs from here
JDK 8 versions
Choose your system info [bit] correctly.
Using older versions will run Flutter and Xamarin applications seamlessly
Or if you have installed JDK#Latest try downgrading them to an older version.

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)

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.
