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 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.

Install any apk from Eclipse

I want to install apk from within Eclipse IDE by right-clicking on apk file (that may be in any project, no need for ADT).
The system command to execute is adb install app-name.apk
How to archive that in Eclipse IDE ?
To run some tool Eclipse External tool may be used (that I don't know well),
but that will not appear in context menu for right-button mouse click.

Eclipse lets you right-click any file, and use Open With -> Other , where you can choose any external program or script. On Windows, I created a simple batch script with below line (you should be able to do something similar on other platforms)
adb install -r %1
and in eclipse, i right-click an apk file, and choose Open With -> Other -> above batch script , Eclipse then successfully installed the APK.
Another option: you can create Eclipse plugin, using its Commands interface. This lets you add a context-menu/right-click action. You can execute your adb command from there. Creating this plugin can be easy, please take a look at this code snippet for a sample.
Ideally you would want to use the -r option so it re-installs if apk already present on device : adb install -r app-name.apk.

How to import android apk

I have been sent an android app to test. I saved the apk to my desktop, but now I don't know what else to do. How do I import it into androis studio? I know this is a very basic question but please be detailed, thank you.

Connect your android device (or start an emulator), go to the command prompt, change directory to where the apk is, and enter adb install apkname

Please follow the below steps to install apk file.
1.First run the emulator.
2. open the sdk specified path and find the platform tools folder.then copy the apk file and store it inside the platform-tools folder.(G:android-sdks\platform-tools).
3.open the command prompt and change the directory to android-sdks/platform tools.
4.enter the command : adb install apkfile name.
5.if you are getting success in command prompt the apk was sucessfully installed in your emulator..

Launch Android SDK manager - Tools directory doesn't exist? Mac

I'm on mac, I think I've done everything right so far. following these instructions:
http://developer.android.com/sdk/installing/adding-packages.html
it says to navigate to tools/ directory in terminal. Here are my steps.
Open terminal
cd Applications
result is: No such file or directory
path to my tools directory is as follows
Applications->adt-bundle-mac-x86_64-20130219 ->SDK -> tools
I tried putting my folder onto my desktop, both the tools folder, and my adt-bundle because I could change directory to my desktop, and when I enter ls to the terminal I see my tools folder, and my adt-bundle is there,
but the problem is when I try to enter
cd tools
or
cd adt-bundle(etc...)
it says that it is not a directory.
what do I do?

Go to this directory:
cd /adt-bundle-mac-x86_64-20131030/sdk/tools
and run:
./android

I recently encountered this issue, and figured I'd post on this for clarification or for anyone still encountering it.
It seems you have to be at the root of the /adt-bundle-mac-VERSION/sdkdirectory in order to execute the "android" command.
I normally cd into the directory until I reach the location of the command, but in this case I encountered the same issue as the original poster.
You must use the tab key to the android command...
ie...
locate your installation /adt-bundle-mac-x86_64-20131030/sdk hit TAB key /tools hit TAB key /android
instead of cd adt-bundle-mac-x86_64-20131030/ cd/sdk cd/tools android
If done properly the SDK manager should launch for you.
Hope this helps anybody out there.

You can launch the SDK Manager by using the GUI:
Launch Android Studio
Create a new blank project
In the toolbar, look for the icon with tooltip "SDK Manager"

A lot of answers have been given here that you should go to /{path-to-your-android-sdk}/tools
and run ./android.
For me, this did not work. When I opened the android file located at my /{path-to-your-android-sdk}/tools directory with a text editor, it contained the following:
#!/bin/bash
echo The "android" command is no longer available.
echo For manual SDK and AVD management, please use Android Studio.
echo For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
exit 1
So the right approach now, is as stated by #Shijil in his comment.
In the directory for your android sdk, you should use:
For SDK Manager:
cd tools
cd bin
./sdkmanager
For AVD Manager:
cd tools
cd bin
./avdmanager
NB For the last command in each of the options above, you will have to supply additional args depending on the operation you want to perform. An example arg that works for both is --list. Running the commands without any args will only display the possible args you could have passed.
Personally, I think using the GUI in android studio is easier. Especially for linux beginners.

Use cd /users/user/...your path.../android-sdk/tools
and then :
./android

Here is your "tools" directory for Android Studio in OS X El Captain(Yosemite also has the same path hopefully):
Users/user-name/Library/Android/sdk/tools
In the terminal, just type: Library/Android/sdk/tools
and hit enter. And you are in the tools folder.
Please note that user-name refers to the mac user

Better open terminal and type which android.
It will tell you the path where you have the package installed.
Then yeah, you just have to execute that path on the terminal.
Your android package might have been installed with Homebrew or others, so the path can be different.
Edit: typo

For me the directory was cd /Users/your_user_name/Library/Android/sdk/tools/
and after that the command was ./android list targets
I hope this can help

When launching ddms from the cli OS X (10.7.3) I get an error: "Failed to get the adb version...."

When launching DDMS from the command line in Lion (10.7.3) I get the following error:
E/adb: Failed to get the adb version: Cannot run program "/Users/stevieo/android-sdk-macosx/tools/adb": error=2, No such file or directory
This makes sense to me because adb is actually in: /Users/stevieo/android-sdks/platform-tools
How can I modify this path so that ddms will launch on my system?
I have looked into the ddms file itself, but cannot decipher its intent.
One note, I do NOT have this issue on Snow Leopard (10.6.8)....
TIA for any thoughts or assistance.
Regards,
Steve O'Sullivan

If you look into your tools directory where you launched ddms, you will see the adb_has_moved.txt which says:
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK,
launch the SDK and AVD Manager (execute the android tool)
and install "Android SDK Platform-tools"
Please also update your PATH environment variable to
include the platform-tools/ directory, so you can
execute adb from any location.
To solve this, I would change your ~/.bash_profile to have a line like:
# --- add Android platform-tools directory
PATH=~/android-sdks/platform-tools:$PATH
export PATH
Make sure to open up a new Terminal window so it will reload ~/.bash_profile
Note that a possible reason why it is working on your 10.6.8 installation is that you may have an older version of the Android SDK, where adb was in still in the tools directory.

If you are trying from eclipse,
Please make sure to create a adb link in /usr/bin/ directory which should solve the problem:
Ex: ln -s /Users//android-sdks/platform-tools/adb /usr/bin/adb
Note: logging as sudo/root may be required
