The android sdk location cannot be at the filesystem root

I have installed Android Studio in the F:\ drive. My Flutter project is in the E:\ drive.
The Flutter plugin is installed in the Android Studio. But when I open my project in Android Studio and I go to the SDK Manager, it shows the following error:
The android sdk location cannot be at the filesystem root
Every package is disabled and the checkboxes are disabled, so I cannot click them to install Android SDK. The "Edit" link next to the error is not working either.

I came with the same problem because of forgetting "sudo"

Using the new android studio (bumble bee version) .
Restart the app and make sure you have an internet access
That will be enough to create the SDK and it’s directories

Just press Edit ( It is clickable) then download and install the required components.

Download the SDK first, and restore the default settings.
You can find the "Restore default settings" feature here.

What you can do is that you click on edit to surely you will get some version of Android that installs it by default and you click on next it will open another configuration verification window and you click on the next one for last it will tell you or It will update the version of android that was downloaded by default and you click again to finish and you can just select other versions of Android. That worked for me. Linux Ubuntu 20.04.4 LTS
Step 1:
Step 2:
Step 3:
Step 4:
Ready!!

For me it was the system language on Windows, I have changed it to English and it worked.

TL; DR
Make sure:
Your user has write permission into Android SDK directory.
ANDROID_HOME is correctly defined with the correct SDK location.
Description
IMHO it is a really bad practice install SDK into user home directory because:
Packages added will be restricted to a single user.
System administrators won't be able to mirror OS images, thus each engineer will have to install SDK manually.
The old school way is according to Linux directory hierarchy as described at The Linux Documentation Project, which consists on:
Ensure your user has adm privileges
Export SDK environment variables
Obey the filesystem hierarchy, installing the IDE and SDK into /opt
The steps above work perfectly on Ubuntu 22.04 and shall work on other distros with minor adjustments.
1. Ensure your user has adm privileges
grep adm /etc/group | grep ${USER}
adm:x:4:syslog,ventura
lpadmin:x:122:ventura
2. Configure environment variables
/etc/profile.d/
├── ...
├── android.sh
├── ...
├── java.sh
└── ...
where android.sh contains
#!/usr/bin/env bash
export ANDROID_HOME=/opt/google/android/
export FLUTTER_HOME=${ANDROID_HOME}/flutter
TOOLS=${ANDROID_HOME}/platform-tools
TOOLS=${ANDROID_HOME}/tools/bin:${ANDROID_HOME}/tools:${TOOLS}
export PATH=${FLUTTER_HOME}/bin:${TOOLS}:${PATH}
and java.sh your JRE directory
#!/usr/bin/env bash
export JAVA_HOME=/usr/lib/jvm/java-18-openjdk-amd64
3. Install Android Studio and Android SDK
Download latest Android Studio and unpack it into /opt/jetbrains/:
VERSION=2021.2.1.16
sudo mkdir -p /opt/google/android
sudo mkdir -p /opt/jetbrains/studio
# Unpack Android Studio into a versioned folder
tar -xvzf android-studio-${VERSION}-linux.tar.gz
sudo mv android-studio /opt/jetbrains/studio/${VERSION}
# Grant write permission to administrators
sudo chown root:adm -R /opt/jetbrains/
sudo chmod g+w -R /opt/jetbrains/
sudo chown root:adm -R /opt/google/android
sudo chmod g+w -R /opt/google/android
Finally launch Android Studio and choose the SDK location:
This approach is extremely powerful because it allows system administrators duplicate development workstations using rsync -avz without relying onto any username or custom privileges.

I searched for many hours for an answer to this
I reinstalled:
I opened a new folder called Android in C:
Into it I reinstalled the android studio
You have created a new SDK folder within it
Then in the blank path, I entered C: \ Android \ sdk
And that's how it all worked.
Try it!

You can clear invalidate caches and restart android studio like follow picture:
Then start download sdk files :)

Make sure that your internet is working and try to close VPN connections if you have any. Then restart Android Studio and hope for the best.

To solve this issue, I had to close Android studio entirely. When I started the application again, it detected that it had a missing SDK problem and then went ahead with the installation process for it.

Your country should not be among the sanctioned countries (using VPN).
Android Studio by Run as Administrator open.
Download : Android SDK and Android SDK Platform.
Fix error: the android sdk location cannot be at the filesystem root.
For test The VPN is working properly.
Open website : https://developer.android.com/

this is the best solution to this error which is just under any drive you have on your laptop which C:// open a folder called "Android" and under the android folder open a folder called "sdk" and change the sdk file path to this recently created folder. That's All.

Android Sdk Manager Failed to download any source list

I'm trying to download platform-tools from Sdk Manager. but when I run :C:\Users\tavak\AppData\Local\Android\Sdk\tools\bin\sdkmanager --list
or any other commands related like \sdkmanager platform-tools
I get this error :
Warning: Failed to download any source lists!
Warning: java.io.FileNotFoundException: https://dl.google.com/android/repository/repository2-1.xml
The antivirus is disabled , and I'm running a proxy in whole device. I can successfully open the url in my browser. help me if possible !

If you are using proxy, you need to specify your proxy settings:
sdkmanager --list --verbose --no_https --proxy=http --proxy_host=127.0.0.1 --proxy_port=8118

maybe the best solution for a person under blockade like me , is using faster proxys or I can download the sdk parts , manually. the needed ones include :
platform-tools
builds
emulator
platforms
...
It really bothers but no way !

How to install SDK manager on linux ubuntu 16.04?

I was trying to install Android SDK with the help of the SDK command line tools downloaded from the link https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip
on my Linux Ubuntu 16.04 PC.
i run the command following command for installation
./android update sdk
but the installation has stopped and gave the following message on terminal
------------------------------------------------------------------------------------------------------------------------------------
The "android" command is deprecated.
For manual SDK, AVD, and project management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
"android" SDK commands can be translated to sdkmanager commands on a best-effort basis.
Continue? (This prompt can be suppressed with the--use-sdk-wrapper command-line argument or by setting the USE_SDK_WRAPPER environment variable) [y/N]: y
Running /home/user/Android/Sdk/bin/sdkmanager --update
Warning: java.net.SocketException: Connection reset
Warning: Failed to download any source lists!
Done
-----------------------------------------------------------------------------------------------------------------------------------
how to solve this error.or suggest me a way to install android sdk on my linux pc without installing android studio.

A bit late, but in the same situation. It looks like this isn't an error, but the way the tools evolved: they are pushing users to use Android Studio if they want the GUI for the sdk manager, it's usable only from the IDE.
You still have the command line available at bin/sdkmanager in this folder from the download, and instructions can be found here, but they are not great, either, so I'll share what I did:
downloaded the latest compressed file from this page (link way down there)
unzipped somewhere (I chose /opt/Android/android-sdk)
created a symlink to add sdkmanager to my path (ln -s /opt/Android/android-tools/bin/sdkmanager ~/.local/bin/sdkmanager)
installed platform tools and build tools for kitkat and up using sdkmanager "platform-tools" "platforms;android-19" "build-tools;19.1.0" (sudo may be needed)
You can check the versions available using sdkmanager --list, and figure what you need to support and download tools for other versions. The download will not show any kind of progress, it'll only tell you it's done after a while.
I suppose it's not a big deal to keep Android Studio installed solely to have access to the sdk manager GUI, but I'll make do with the command line tools. That's very shady of Google, specially to people not really into their hacked up Intellij version.

I can't install Android Studio

I use Ubuntu 14.04 LTS.
My JDK version is 1.8.0_31.
I downloaded Android Studio archive, unpacked it and ran a studio.sh file. But every time the installation begins an error occurs:
Refresh Sources:
Failed to fetch URL http ://dl-ssl.google.com/android/repository/addons_list-2.xml, reason: File not found
Fetched Add-ons List successfully
Refresh Sources
Failed to fetch URL http ://dl-ssl.google.com/android/repository/repository-10.xml, reason: File not found
Refresh Sources:
Failed to fetch URL http ://dl-ssl.google.com/android/repository/repository-10.xml, reason: File not found
There is nothing to install or update.
The following SDK components were not installed: build-tools-21.1.1, source-21, sys-img-x86-addon-google_apis-google-21, extra-android-m2repository, android-21, extra-google-m2repository, addon-google_apis-google-21, platform-tools
Moreover, when I run the studio.sh file following text appears in terminal:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=350m; support was removed in 8.0
Also I tried to install the Android Studio from Paolo Rotolo's repository, but the same problem occurs.
I am rookie in Ubuntu, so I hope only for your help.

I also met this problem. Even I can download the xml files from browser, the android update sdk process keep reporting file not found. A search from google leads me to here:
https://code.google.com/p/android/issues/detail?id=76268
The first anwser reminds me of permission problem of ~/.android. I checked, and found that this hidden directory is not owned by me. Change the owner of the directory solve the problem.

Its not that tough actually, just follow the following steps:
first of all make sure your ubuntu is uptodate. open >Unity>Software updater.
Install latest Jdk - in my case its Java8
Installing java
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
Make it default version
sudo apt-get install oracle-java8-set-default
Installing Android Studio
Download Android Studio from here, use All Android Studio Packages
Extract the archive file into an appropriate location for your applications, eg: /opt. Use the filename of your downloaded archive, in my example android-studio-ide-141.2178183-linux.zip
sudo unzip android-studio-ide-141.2178183-linux.zip -d /opt
To launch Android Studio, navigate to the /opt/android-studio/bin directory in a terminal and execute ./studio.sh. Or use a desktop file, see below. Make sure you type "./studio.sh"
You may want to add /opt/android-studio/bin to your PATH environmental variable so that you can start Android Studio from any directory.

sudo studio.sh
running it as root solved for me

the sdk manager won't open after trying everything

I have installed the Android SDK but I can't get the Adroid SDK manager to open.
I have looked everywhere on the internet and this is what I have already done which didn't help:
1. run sdk as administrator
2. adding a path pointing to the JDK in all of these forms :
C:\Program Files\Java\jdk1.7.0_21\bin;%SystemRoot%\system32;
C:\Program Files\Java\jdk1.7.0_21\bin;
C:\Program Files\Java\jdk1.7.0_21\
C:\Program Files\Java\jdk1.7.0_21
C:/Program Files/Java/jdk1.7.0_21/bin;
none of them worked ..:-(
3.
Step #1: Open up a command prompt.
Step #2: Use the cd command to move to wherever you installed your Android SDK.
Step #3: Run tools\android.
after doing it I got an error message that said that :
ERROR: No suitable Java found. In order to properly use the Android Developer
Tools, you need a suitable version of Java installed on your system.
4. deleting 3 times the sdk and reinstalling it.
5. Deleting the .android folder from the user (C:/Users/[User Name]) directory
By the way I have Windows 7 , and I have downloaded the 64 -bits sdk.
I am so helpless.. I ll appreciate a lot a solution...
Shiran

I had the same problem. Try to add an environment variable :
JAVA_HOME : "C:\Java\jdk1.7.0_25\".
It solves problem for me.

WRT Ubuntu 14.04:
You may not have java installed globally in your machine. My fix was to do:
sudo apt-get install openjdk-7-jdk
After was I able to run the SDK Manager.
