Unable to find bundled Java version on Flutter

Question

I have Android Studio version 3.0. When I use the command flutter doctor it shows me the following:

Unable to find bundled Java version

My current Java version is (build 1.8.0_131-b11) on Windows 10.

I don't have any older versions of Android Studio on my computer.

Answer 1

Rename the "jbr" file to "jre" within C:\Program Files\Android\Android Studio\jbr. Once done, open a new command prompt to check if the bundle error has been cleared, as illustrated in https://www.youtube.com/watch?v=u7q6MQNAsIc.

System in use - Windows

Answer 2

I faced the same issue, and I solved it by going to this path:

C:\Program Files\Android

you will find folders like this:

• Android Studio1
• Android Studio2
• Android Studio3
• Android Studio4

delete all of them and leave just the latest which in this case is "Android Studio4"

run flutter doctor again and it should work

Answer 3

for windows :

1.run CMD as Administratormklink.

2.go to android studio path.

3.taype in cmd

mklink /D "jre" "jbr"

Answer 4

Double check the path, solved my problem wrapping the path with quotation marks...

Before:

flutter config --android-studio-dir D:\Android\Android Studio

After:

flutter config --android-studio-dir "D:\Android\Android Studio"

Answer 5

For MacOS users, follow this please:

1. Open this path: /Applications/Android Studio.app/Contents/
2. If there is no jre folder, then create it manually
3. Copy all contents of jbr folder, and paste them into jre folder
4. Go back to Terminal and run flutter doctor -v and the error should be cleared

Answer 6

Answer 7

Right approach

In short and simple, the best approach to fix this issue is by upgrading your Android Studio and Flutter to latest versions, in order to avoid any potential issues (e.g. patching) in future.

Original answer

For those having these issues with the latest Android Studio - Electric Eel version, and other canaries and preview releases, note that the bundled jre directory in the Android Studio installation folder is now renamed to jbr

To resolve this, just create a sym link jre -> jbr and Flutter won't complain.

On Linux

cd ~/android-studio/ && ln -s jbr jre

Windows (check installation folder)

cd C:\Program Files\Android\Android Studio
mklink /D "jre" "jbr"

or

New-Item -ItemType SymbolicLink -Path .\jre -Target .\jbr

Mac OS

cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre

---

Note that if you are running a preview release, and depending on your OS, the default installation directory might be different, e.g. on Linux it would be

~/android-studio-preview/

In either case, you can check the installation directory by running

flutter doctor -v

---

Also, in case if you run with permissions issues, you can try running the command with admin privileges, depending on your OS.

For example on Mac/Linux, you can just run the same command with sudo and it should work, additionally on Mac, you'll have to configure the Disk Access permissions, depends on your version, but most probably can be found under:

Settings - Privacy & Security - Full Disk Access - Terminal

Answer 8

In my case, I am using macOS, there was a copy of Android Studio Preview in my Downloads folder. I just deleted that Android Studio Preview file and the error was gone.

Answer 9

Go to Finder > Applications > Android Studio:

1. Right click and click "Show package contents"
2. Create a new folder called jre
3. Copy the contents of the jbr folder and paste them into the jre folder

Answer 10

For Windows users:

Go to C:\Program Files\Android\Android Studio, then copy the contents of jbr and paste the contents into the jre folder.

Run flutter doctor again and it will solve the problem.

(I'm running Android studio 2022.1)

Answer 11

If you are using Ubuntu and used JetBrains Toolbox then just do one thing: Go to the Android Studio directory /home/shahadat/.local/share/JetBrains/Toolbox/apps/AndroidStudio/ch-0/222.4459.24.2221.9862592 address path will look like this.

if you do not know how to find out the Android studio path from the JetBrains toolbox or anything else then type flutter doctor -v and then check Android Studio Section (Version 2022.2) - The version can vary.

Then just copy the jbr directory and rename the directory/folder as jre.

Now run flutter doctor -v

This works for me.

Answer 12

For Mac Users:

Set the JAVA_HOME path by following this article and then apply the following commands:

For the JetBrains Runtime "Android Studio Electric Eel"

cd /Applications/Android\ Studio.app/Contents/jbr
ln -s ../jbr jdk
ln -s "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" jdk

Then go to the Finder and search for Android Studio:

1. Right click -> Show Package Contents
2. Open the contents folder, then create new folder called jre
3. Copy the contents of the JetBrainsRuntime folder and paste it into the jre folder

flutter doctor -v should work now!

Other versions

cd /Applications/Android\ Studio.app/Contents/jre
ln -s ../jre jdk
ln -s "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" jdk

Then you can run flutter doctor -v

---

For Mac users who are using the JetBrains Toolbox:

Set the JAVA_HOME path following the article.

After that, change username to your macOS username and run:

cd /Users/username/Library/Application Support/JetBrains/Toolbox/apps/AndroidStudio/ch-0/203.7583922/Android Studio.app/Contents/jre
ln -s ../jre jdk
ln -s "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" jdk

flutter doctor -v

If you're still facing the issue, you can try this workaround:

cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre

Answer 13

WINDOWS SOLVED (Android studio 2022.1.1)

Go to "C:\Users\user\AppData\Local\JetBrains\Toolbox\apps\AndroidStudio\ch-0\221.6008.13.2211.9477386" then copy the content of jbr and paste the content into jre folder

run doctor again and problem solved

Answer based on GAYTH BACCARI post. Thanks

Check if path in the enviorment variables are added for JAVA

Answer 14

For Mac Users

Make sure you have installed java and set the java_home path, you can use homebrew for that.

If you installed Android Studio Electric Eel Follow the following step

1. Go to your Applications folder.
2. Search for Android Studio.app. (flutter doctor -v also has an Android Studio entry which will show you the app location)
3. Right click and select Show Package Content.
4. Navigate into the Content Folder that opens.
5. Use your terminal to cd into that folder and then enter the command below and everything should be solved

ln -s jbr jre

The command above creates a symbolic link

The symbolic link also works on Ubuntu.

Answer 15

For Windows Go To android studio directory (Default C:\Program Files\Android\Android Studio) remove jre folder run cmd as administrator

cd C:\Program Files\Android\Android Studio

mklink /D "jre" "jbr"

and it will work

Answer 18

Solution for Mac

Go to finder and find Android studio:

• right click and click show package contents
• Create a new folder called jre
• copy the contents of the jbr folder and paste them into jre folder
• reload your terminal and type flutter doctor

Chill Pill :)

Answer 19

In latest version of Flutter for Mac, you won't find jre folder under /Applications/Android Studio.app/Contents

Therefore, you can start Terminal and run following commands to fix the issue:

cd /Applications/Android Studio.app/Contents

ln -s jbr jre (creates a symbolic link (shortcut) named jre pointing to jbr)

If you're on latest version of Mac, you might see error while trying to make changes under Applications folder using Terminal, resolve it by adding sudo, like this:

sudo ln -s jbr jre (runs the above command as admin, it will ask you for Mac password)

You might still see security alert, then you must go to System Settings > Privacy & Security > App Management and Terminal as in the list of apps allowed to make changes under Applications folder.

Answer 20

For Android Studio Preview

I already install

• Android Studio Preview
• JDK via Android Studio Preview
• Xcode v12 on MacOS 10.15

Here is what I faced [!] Android Studio: Unable to find bundled Java version.

Solution:

1. Find out JDK PATH. Check this

#check bash or zsh

$ echo $SHELL
/bin/bash

#return the path of java_home 
$ /usr/libexec/java_home

2.Add JAVA_HOME in .bash_profile for bash or .zshenv for zsh

$ nano ~/.bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source ~/.bash_profile

3.Link JDK path to Android Studio Preview

$ cd /Applications/Android\ Studio\ Preview.app/Contents

# flutter doctor check if Contents/jre exist, link jbr with jre
$ ln -s jbr jre

$ cd jbr
$ ln -s ../jbr jdk
$ ln -s "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin" jdk

4.[Optional] if you have Android Studio at the same time, you could follow @Nalawala Murtuza solution. It is permitted for Android Studio and Android Studio Preview at the same time during check from flutter doctor. Doesn't need to delete Android Studio Preview.

5.Use flutter doctor -v to check
