Android SDK cannot be found by flutter

Question

I have installed flutter through AUR. I also have aur/android-sdk 26.0.2-1 installed. When I run flutter run I get:

Warning! This package referenced a Flutter repository via the .packages file that is
no longer available. The repository from which the 'flutter' tool is currently
executing will be used instead.
  running Flutter tool: /home/dair/.flutter-sdk
  previous reference  : /home/dair/flutter
This can happen if you deleted or moved your copy of the Flutter repository, or
if it was on a volume that is no longer mounted or has been mounted at a
different location. Please check your system path to verify that you are running
the expected version (run 'flutter --version' to see which flutter is on your path).

Unable to locate a development device; please run 'flutter doctor' for information about installing additional components.

Firstly, I ran flutter --version, and received:

Flutter • channel alpha • https://github.com/flutter/flutter.git
Framework • revision e2f54df5ab (9 days ago) • 2017-06-02 10:43:54 -0700
Engine • revision 1f2aa07571
Tools • Dart 1.24.0-dev.3.0

Not sure what exactly it means by "to see which flutter is on your path". Next I ran flutter doctor and got:

[✓] Flutter (on Linux, locale en_US.UTF-8, channel alpha)
    • Flutter at /home/christopher/.flutter-sdk
    • Framework revision e2f54df5ab (9 days ago), 2017-06-02 10:43:54 -0700
    • Engine revision 1f2aa07571
    • Tools Dart version 1.24.0-dev.3.0

[✗] Android toolchain - develop for Android devices
    ✗ ANDROID_HOME = /opt/android-sdk
      but Android SDK not found at this location.

[✓] Android Studio (version 2.3)
    • Android Studio at /usr/local/android-studio
    • Gradle version 3.2
    • Java version: OpenJDK Runtime Environment (build 1.8.0_112-release-b06)

[✓] Connected devices
    • None

However, if I cd into /opt/android-sdk I get:

➜  ~ cd /opt/android-sdk 
➜  android-sdk ls
add-ons  build-tools  emulator  platforms  tools

So it looks like it is there. The closest question I could find is this one: React Native android build failed. SDK location not found but it seems to be using Mac as opposed to arch as well as some other differences. How can I resolve the flutter doctor and have my app run?

Answer 1

I was running into the same problem when I was trying the flutter doctor command:

The problem is a little clearer: it's occurring because Flutter is not finding the path for your Android SDK.

There are two ways to solve it:

• You can solve this issue by setting the SDK path for your current terminal instance with the following commands:

  flutter config --android-sdk /path/to/android/sdk

  flutter config --android-studio-dir /path/to/android/studio

• Or to save it permanently, export the ANDROID_HOME with your Android SDK path.

I solved it by exporting the ANDROID_HOME on my machine (Arch Linux, but this works for any Unix instance).

This will solve your issue, but you may need the sdk, platform-tools, tools, and the ndk-build paths as well (of course, everything needs to be installed first) in your profile file (in my case, the .zshrc file; the same can be done in your .bashrc, etc.):

# SDK exporting - this will solve your issue
export ANDROID_HOME=/home/{user}/Android/Sdk 

# Tools exporting - it may be needed in your case
export PATH=/home/{user}/Android/Sdk/platform-tools:$PATH
export PATH=/home/{user}/Android/Sdk/tools:$PATH
export PATH=/home/{user}/Android/ndk-build:$PATH

# Flutter binary exporting
export PATH=/home/{user}/flutter/bin:$PATH

Then, I reloaded my profile file (in my case, the .zshrc file; use your file in your case, e.g., .bashrc):

source ~/.zshrc

After that, the flutter doctor command will run properly.

Answer 2

For me, the Android SDK command-line tools were missing, i.e. installing Android Studio did not install the command-line tools automatically.

I had to run Android studio and use the included SDK manager to install the Android SDK Command-line Tools

Start Android Studio, select More Actions... > SDK Manager, select the SDK Tools tab, make sure to check Android SDK Command-line Tools (latest), click Apply. This will install the Android SDK command-line tools.

After that, flutter doctor completed successfully. No need to set flutter config --android-sdk ... etc.

Answer 3

I experienced the same issue and solved it with these simple steps:

1. Open Android Studio.
2. In the top navigation bar, click Tools -> Android SDK.
3. Copy the Android SDK location path, for example /Users/yourname/Library/Android/sdk
4. Click 'Edit' next to the Android SDK location.
5. Check Android SDK option/s (this might already be pre-selected).
6. Click 'next' then continue installation.
7. Restart Android Studio.
8. Open the Android Studio terminal and command flutter config --android-sdk pastetheAndroidSDKlocationpathhere.
9. Run flutter doctor.

Answer 4

I'm going to write my experience here on a mac. The real difference to the other answers is that I was confused as to where the installs were, where they should be found and also how confusion was caused by multiple versions of both Android Studio & the sdk existing on my mac.

You to need find two main directories; the sdk location and the installation directory of Android Studio.

sdk

The sdk seemed to have been installed twice and referenced in different places. One of which was installed by brew so I uninstalled that one. The one I ended up referencing is the following. I think that is the proper location on a mac (don't use brew)

/Users/myusername/Library/Android/sdk/

sdk references

Run this command

flutter config --android-sdk sdk_path_here

and set these environment & path variables

export ANDROID_HOME=sdk_path_here 
export PATH=sdk_path_here/platform-tools:$PATH
export PATH=sdk_path_here/tools:$PATH

Android Studio reference

Again there were multiple installs and multiple locations of Android Studio. You may have installed yours manually and it would be installed in the following location

flutter config --android-studio-dir=/Applications/Android\ Studio.app

but I had updated to the JetBrains Toolbox so mine was installed there (I uninstalled the other version of Studio). The one I referenced was

/Users/yourusername/Applications/JetBrains\ Toolbox/Android\ Studio.app

So I ran the following to set the Android Studio location

flutter config --android-studio-dir=/Users/yourusername/Applications/JetBrains\ Toolbox/Android\ Studio.app

After that I still was presented with an error but I restarted my whole machine, deleted previously created AVDs in Studio's Device Manager and then everything did indeed work as expected.

Answer 5

We need to fix this in the tool. You can work around this locally by running flutter config --android-studio-dir='C:\Program Files\Android\Android Studio' , which you can check with explorer. For me this path is C:\Program Files\Android\Android Studio\

Answer 6

In my case, I have to accept the android licenses

run this command in the terminal or android studio terminal

flutter doctor --android-licenses

Answer 7

I had a similar error. Adding Flutter path of extracted flutter sdk till flutter fixed it

Answer 8

flutter config --android-studio-dir <path where android studio is installed>

In my case it was "C:\Program Files\Android\Android Studio"

try with double quotes in the command( I tried with double quotes, which might be necessary if there is space in the path)

Source: https://flutter.dev/docs/get-started/install/windows#android-setup

Answer 9

For Windows: Inside Android Studio, get path from : Apprearance & Behaviour > System Settings > Android SDK > Android SDK path

Make sure your path does not contain any spaces in them, if you have edit path and re-install sdk to a different location.

After that,

flutter config --android-sdk {path}
flutter doctor --android-licenses

You are set!

Answer 10

Under Windows 10 (without Android Studio) I noticed that folder 'sdk/build-tools' is empty. Then I solved this problem by executing:

sdkmanager build-tools;30.0.3

where 'build-tools;30.0.3' was obtained in an output of "sdkmanager --list >list.txt" command.

And, after build-tools's installation the error "Android SDK cannot be found by flutter" was solved too!

PS. It is absolutely essential to read carefully the documentation (there were although another mistakes by me)

PS.PS. The log (for illustration):

Answer 11

Windows command to fix SDK path

As mentioned above by others, using the below command works:

flutter config --android-sdk /path/to/android/sdk

Remember to put quotes in the /path/to/android/sdk

Example: flutter config --android-sdk "C:\Users\UserName\AppData\Local\Android\Sdk"

Answer 12

You Can follow the first answer above. I would like to add a tip. If you are on windows and installed sdk on a path that requires admin rights to modify, then flutter doctor might fail to recognise the sdk. Copy the sdk folder to another non-admin location and then run flutter config --android-sdk command.

Answer 13

for me, it was very simple.

this kind of issue usually happens if IDE unable to load SDK.

so to solve this follow below steps:

goto file menu -> project structure -> project settings -> select "project"

now set Android SDK path with existing java version.

then select "modules" and configure Android SDK and click on apply and then click ok.

now we may find both ios and android emulators to run your flutter app on both devices.

Answer 14

If you're using Android Studio 3, you can configure your platform SDK by going to File -> Project structure and choose your platform SDK.

Hope this works for you.

Answer 15

For Windows 10 Version 2004

I added a user environment variable named ANDROID_HOME and value is {SDK-PATH}\build-tools\{SDK-VERSION}. You have to replace SDK-PATH and SDK-VERSION for your custom values.

And I appended another value named %ANDROID_HOME% to system PATH variable.

Then it worked as expected.

Answer 16

For macOS Catalina: If you have installed android sdk to a custom location (say /Users/your_username/dev/android/sdk) then follow these steps (NOTE: You must change the location according to your sdk location):

1. Open zshrc file

   nano ~/.zshrc

2. Add the following to the zshrc file

   export ANDROID_HOME=Users/your_username/dev/android/sdk
export ANDROID_SDK_ROOT=$ANDROID_HOME
export ANDROID_AVD_HOME=$HOME/.android/avd
   

3. Save and close nano using Ctrl+x, when prompted type y

4. Source your zshrc file using

   source $HOME/.zshrc

5. You can check whether your problem is fixed by typing the following in a terminal window. You should get the sdk path as your output

   echo $ANDROID_SDK_ROOT

Answer 17

Go to the project structure and make sure the sdk version is selected.

Answer 18

in environment variables make Variables: ANDROID_HOME

and add path of SDK get from Andriod stideo --> settings --> SDK Coppy the Path examlpe

:C:\Users\Omar\AppData\Local\Android

Add the SDK path in variables Value: C:\Users\Omar\AppData\Local\Android

Next Step: Add 2 value in path variables :

 %ANDROID_HOME%\tools 

%ANDROID_HOME%\platform-tools

Answer 19

To get the Android SDK path - Open Flutter project in Android Studio - Go to File > Project Structure > SDK Location. Copy the location

To set the Android SDK path - Type in terminal flutter config --android-sdk /path/that/you/just/copied

Answer 20

I've set up my Android SDK manually on Windows 10 with the command line, I think this not change a lot in Linux, and I was able to solve this kind of errors while I tried to set up my development environment, if you want to solve it as I did, just follow the next steps that I posted in a GitHub Comment in a related issue:

https://github.com/flutter/flutter/issues/19805#issuecomment-478306166

I hope this can help anyone need it! Bye!

Answer 21

The solution at https://github.com/flutter/flutter/issues/15114#issuecomment-376582281 worked for me, this worked after adding $ANDROID_SDK_PATH\platform-tools to user path variable.

Answer 22

I suffered alot trying to find a solution to it and finally I found the solution by configuring the project SDK
File -> Project structure then choose sdk platform.

Answer 23

i have solved! i put my android SDK before in F:/androidsdk so when i run "flutter config" android sdk doesnt linked. To link flutter wiht android sdk just type command below:

flutter config --android-sdk /path/to/android/sdk

i just change with this

flutter config --android-sdk F:/androidsdk

i hope this is working.

Answer 24

It is saying that your project is using two different path of flutter-sdk. There are two place where sdk paths are defined.

1. Setting (Setting > Language&Frameworks > Flutter > Flutter SDK path)

2. local.properties in your root folder

These both place should contain same path to sdk.Compile with flutter run !! done !!

Answer 25

I have solved this problem by the following command flutter config --android-sdk <sdk-location> Where is the location for your sdk. If you're on windows make sure to use double quotes.

Answer 26

Flutter requires the Android SDK platform tools so that it can use the adb command line tool.

It looks like you've installed the Android SDK but you haven't installed the platform tools yet.

Here is the android-sdk-platform-tools Aur package for arch and a guide for how to install it.

Possibly the error message could be improved to indicate that we are actually missing the Android SDK platform tools rather than the Android SDK itself. If you want to, feel free to send a pull request or open an issue.
