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.

set android home in ubuntu

i downloaded the sdk from android official website and installed the latest build tools using android sdk manager. I set android home as said here
but when i run cordova build android i got ANDROID_HOME is not your path.
Then i did as same as here but no luck.
Please help me to solve this.

Please verify that the SDK you downloaded really is located at the location you set. Do this by:
echo $PATH
and
echo $ANDROID_HOME
and verify that the last part of PATH and ANDROID_HOME is identical with where you unzipped the Downloaded zip.
If referring to here than you would have to replace "/opt/android/sdk" with the folder where you unzipped the SDK.
If using sudo you need to either call sudo with sudo -E flag or add the ANDROID_HOME to the Defaults env_keep in /etc/sudoers

Cordova and setting Android using command line

I am trying to migrate my existing project from cordova 2.1 to the latest, 3.1 which can be installev vía command line,
I already have the Android SDK installed,
So:
sudo npm install -g cordova // All good
cordova create hello com.example.hello HelloWorld // All good
cordova platform add android // Then it fires:
Checking Android requirements...
[Error: The command `android` failed. Make sure you have the latest Android SDK installed, and the `android` command (inside the tools/ folder) added to your path. Output: ]
So I installed Macports and tried:
sudo port install android
Which logs:
Warning: All compilers are either blacklisted or unavailable; defaulting to first fallback option
Warning: Xcode does not appear to be installed; most ports will likely fail to build.
---> Cleaning android
---> Scanning binaries for linking errors: 100.0%
---> No broken files found.
Any idea what am I missing here?

It's work cordova Android for MAC 1000000000%. I fought solution and now i'm working try this #Toni Michel Caubet. I will happy to share my Answer.
STEPS:
Open Your Terminal and followed by,
touch ~/.bash_profile
open ~/.bash_profile
PATH="/Users/System-Name/Documents/android-sdk-macosx/sdk/tools:/Development/android-sdk-macosx/sdk/platform-tools:$PATH" (This is Android SDK Location to stored in My system )
4.Save the file and quit the text editor.
5.Execute your .bash_profile to update your PATH:
source ~/.bash_profile
if you want to see your environment path:
7.In your terminal type: set
After you can see like
8.As far as your made it very correct. After your enter command like cordova platform add android. you get following error. because Java SDK doesn't too set environment PATH.
9.open ~/.bash_profile. Add JAVA_HOME value
10.You can see your environment like STEP 7 set. You should be able see:
11.Successfully created environment now you can create Android project with Cordova or PhoneGap

When you installed the Android SDK, it will come with a bunch of folders, like build-tools, platform-tools, tools, and some others. You need to add platform-tools and tools to your main $PATH environment variable.
See the docs here about how to add things to your PATH for whichever system you are on (Windows or Mac): http://cordova.apache.org/docs/en/3.1.0/guide_platforms_android_index.md.html#Android%20Platform%20Guide
Here is how you would edit the $PATH on Windows:
Click on the Start menu in the lower-left corner of the desktop,
right-click on Computer, then click Properties.
Click Advanced System Settings in the column on the left.
In the resulting dialog box, press Environment Variables.
Select the PATH variable and press Edit.
Append the following to the PATH based on where you installed the
SDK, for example: ;C:\Development\adt-bundle\sdk\platform-tools;C:\Development\adt-bundle\sdk\tools
Save and close both dialogs.

To install the cordova command-line tool, follow these steps:
First of all go through the Cordova Document
For Cordova command-line tools to work, you need to include the SDK's tools and platform-tools directories in your PATH environment. On Mac, you can use a text editor to create or modify the ~/.bash_profile file, adding a line such as the following, depending on where the SDK installs:
export PATH=${PATH}:/Development/adt-bundle/sdk/platform-tools:/Development/adt-bundle/sdk/tools
Next Steps:
Download and install Node.js from Here. Following installation, you should be able to invoke node or npm on your command line.
Install the cordova utility. In Unix(Mac), prefixing the additional sudo command may be necessary to install development utilities in otherwise restricted directories:
For Mac $ sudo npm install -g cordova
once successful installation of cordova is done ,now you can create your application
across all the platforms.
Create the Cordova Application
Go to the directory where you maintain your source code, and run a command such as the following:
$cordova create hello com.example.hello CordovaDemo
hello is the directory where you want to create your application
com.example.hello is the package name
CordovaDemo is the name of the Application
Once Successful creation of your project, some file will be created inside the directory i.e hello
Add Platforms
All subsequent commands need to be run within the project's directory, or any subdirectories within its scope:
$ cd hello
Now you need to specify a set of target platforms, Supported OS for Mac
$ cordova platform add android
plz tell me if you are still having problem.
[Error: The command `android` failed. Make sure you have the latest Android SDK installed, and the `android` command (inside the tools/ folder) added to your path. Output: ]
You just need to install the Latest version of Android i.e 4.3
Go to SDK Manager and install the latest SDK Platform.
And try run the command again.
Hope this will help you.

Here it solved my issue:
into the terminal.
touch ~/.bash_profile (create a bash profile)
open ~/.bash_profile (opening a bash profile)
in your opened file, please type the following, Make sure that you have given the correct path, in case you find it difficult to find your directory in which your Android SDK is installed , search into your terminal with ls -l.
PATH="/Users/System-Name/Documents/android-sdk-macosx/sdk/tools:/Development/android-sdk-macosx/sdk/platform-tools:$PATH"

[Let me clarify first that, this is windows specific suggestion, answer]
For particular cordova version there corresponds particular android API
So,
First check out version of cordova with following command:
$ npm cordova -v
In my case cordova version was 1.4.28 , which corresponds to Android API 19
So the bottom line is don't waste time in downloading all "SDK Platforms"
instead just download corresponding Android API for concerned cordova version...
Hope this help....!!!

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

Building liblinphone for Android

I am building Linphone application for android. I am using windows xp 32 bit.
1) Download android ndk
2) Installed the autotools: autoconf, automake, aclocal, libtoolize pkgconfig
3) run the ./prepare_sources.sh/
I got the output in terminal as
$ ./prepare_sources.sh /cygdrive/d/android/androidNdk/android-ndk-r8d
using /cygdrive/d/android/androidNdk/android-ndk-r8d as android NDK
./prepare_sources.sh: line 23: git: command not found
Applying patch to ffmpeg

Any info, questions or anything really is highly appreciated

Part 1
The following steps can help you create and install the build on your device or emulator(Tested on Mac):
Step1: you need to have the Android SDK and NDK configured and istalled
Also install Autotools Mac users can use this link (Follow point 2.3 only in the link)
Other platform users please make sure you install it correctly.
Step2: Mac users open up your terminal and clone the git repo on any directory you want
to by running the following command: (Other users sorry i don't know how but i think you can figure it out that how you can get the git repo on your directory using command promt or whatever you are using)
$ git clone git://git.linphone.org/linphone-android.git --recursive
After you get the Repo copied into your directory now go to the directory and open the README file and read out the whole file.
Step3: Now we will follow as the instructions written in README file
First Go to root directory of the downloaded project using the following command on Terminal:
Mac users on terminal write cd and
then drag and drop the "linphone-android" folder on terminal
(when you drag and drop the folder terminal will get the path of the folder and then you can hit enter to get into the directory of that folder)
$ cd /Users/myname/Desktop/Android/linphone-android
or just use simple command cd to get into the folder
$ cd Desktop
$ cd Android
$ cd linphone-android
Now when you get into the directory on terminal then check your PATH of SDK & NDK installed on your Mac run
$ echo $PATH
if you see the path with SDK and NDK location then it's ok to proceed with Step4 and skip the below part and if not then you need to setup the PATH before you execute the make and make install script in Step 4:
To set up path use :
$ export PATH=/Users/myname/Documents/adt-bundle-mac-x86_64-20130729/sdk/platform-tools:/Users/myname/Documents/adt-bundle-mac-x86_64-20130729/sdk/tools:/Users/myname/Documents/android-ndk-r9:$PATH
it's like export PATH=(Path of your SDK platform tools folder):(Path of your SDK tools folder):(Path of your NDK folder):$PATH
This will set up the path and to confirm again run
$ echo $PATH
Now you will see that the path of SDK and NDK is there.
Step 4: Now if the Path is already setup you can simply run
$ make
Now connect your Device to you Mac/Pc and see if eclipse has detected it.
After the device is connected run:
$ make install
$ make generate-sdk (optional)
This will install the application into your phone. (you need to have an working SIP username and password to configure in the app)
This above steps worked for me and i was able to get the app running on my device.
Part 2
Importing into Eclipse :
After you have made your build then now you need to import it into eclipse.
Step1: Go to eclipse click on File Menu then Import then select
Existing Android Code into Workspace
Hit Next and Browse to the linphone-android project folder
And Only tick linphone-android folder and Leave Copy project into workspace untick.
Do this Like the below image:
And hit finish.
Now you right click on "linphone-android" (project name) and go to Properties and Java Build Path and then Order and Export and then reorder them as my image below and untick gcm.jar
Hit OK
And Boom No errors
Now just run it on device or emulator. (Make sure your minimum target SDK matches with your device or emulator.)
The above steps worked fine for me and it will work for you as well.
All the Best !!

According to README in root dir of linphone-android you don't need to run prepare_sources.sh, remaining steps for you is to run "make" and "make install":
LINPHONE for ANDROID
**************
To build liblinphone for Android, you must:
0) download the Android sdk with platform-tools and tools updated to latest revision (at least API 16 is needed), then add both 'tools' and 'platform-tools' folders in your path.
1) download the Android ndk (>=r8b) from google and add it to your path.
2) install the autotools: autoconf, automake, aclocal, libtoolize, pkgconfig
2bis) on some 64 bits systems you'll need the ia32-libs package
3) run the Makefile script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
$ make
4) To install the generated apk into a plugged device, run
$ make install

Existing answers shows how to build old linphone but to Build Latest Linphone for Android You can follow these Steps:
1) First Download Android SDK (at least API 16 is needed)
2) Then Download Android NDK(>=r9d) from Google.
3) Then Install cmake, python, yasm nasm Dependencies which is further required while installing Linphone. you can install these tool through Terminal.
4) Then You have to download source code of Linphone using following command:
git clone git://git.linphone.org/linphone-android.git --recursive
5) After Downloading Source code You have to set Path of Android SDK,NDK and also JDK
in Android SDK You have to give path upto Tools.
For Example : in console type following command
export SDK_PATH=/home/rajesh/android/adt_bundle/sdk
export NDK_PATH=/home/rajesh/android/android-ndk-r10c
export JDK_PATH=/usr/lib/jvm/java-7-openjdk-i386/
export PATH=$PATH:$NDK_PATH:$SDK_PATH/platform-tools:$SDK_PATH/tools:$JDK_PATH
6) After setting path you have to navigate through Linphone directory and type command “./prepare.py” then This will configure the build and generate a Makefile in the top level directory.
If you get following error: CMake Error Could not find the intltoolize program then
Refer
http://lists.nongnu.org/archive/html/linphone-users/2015-07/msg00092.html
7) After setting path you have to navigate through Linphone directory and type command “make” then it will generate apk for Linphone.
8) To generate a liblinphone SDK zip containing a full jar and native libraries, run
$ make liblinphone-android-sdk
I hope this helps.
