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:

  1. 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.)

  2. Set the "JAVA_HOME" Environment Variable:

    • Open Windows Search, type in “env”, and choose “Edit the system environment variables”.

      enter image description here

    • 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>")

      Screenshot

    • Click "OK" and close all dialogs.

  3. 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

    If you have installed Android Studio from the website and not using snap, run `flutter config --android-studio-dir=/usr/local/android-studio` – thetanuj Dec 09 '20 at 18:29

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.

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,

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/"

  1. Install Android Studio (skip this step if you already installed)

  2. Goto C:\Program Files\Android\Android Studio\jre and copy the path.

  3. Make New variable called "JAVA_HOME". And paste above path as the variable value.

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

Go To Folder

Bash_Profile

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.

echohome

Add or Edit the Java Home Path

Then open your zshrc in a similar manner as you did with bash_profile and add the home path to the file.

zshrc 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.

bashprofile and zshrc

After that,save,exit the terminal, close android studio and restart your machine.
