A newer version of the Android SDK is required. To update, run:

How can i solve this challenge?
I solved this problem by installing the command line tool.
And then rerun
flutter doctor --android-licenses
I have followed these steps. It worked for me.
went to Environment variables and added ANDROID_HOME with a variable value of:
C:\Users\%username%\AppData\Local\Android\Sdk
then my JAVA_HOME with this variable value:
C:\Program Files\Android\Android Studio\jre
then my Path with this variable value:
C:\Users\%username%\flutter\bin
then I ran the following command
flutter doctor
Got the output of Doctor summary (to see all details, run flutter doctor -v):

Then I ran

and accepted all Terms & Conditions with (y)
Install Android SDK Command-line Tools on android studio using the SDK manager
Run flutter doctor --android-licenses
Now this problem with the license has got to do with the java development kit(JDK) version.
For some reasons if you are not using JDK 8 or below, you will unfortunately get license issues.So basically uninstall current version and install JDK 8 or below. Check link below and follow the conversation carefully.

I solved pb (jdk11 on Win10 at beginning) following Nitesh steps (thanks) but with some change due to win10 strange behavior ( i know...).
To objectify, create two environment'variables with win10 wizards :
I strike :
TEST1 C:\Users\%username%\XXX
TEST2 %USERPROFILE%\YYY
Appear correct in wizard:
TEST1 C:\Users\pirla\XXX
TEST2 C:\Users\pirla\YYY
But in a dos command window, this comes to SYSTEM in first case despite correct username :
C:\Users\pirla>echo %username%
pirla
C:\Users\pirla>set TEST
TEST1=C:\Users\SYSTEM\XXX
TEST2=C:\Users\pirla\YYYY
So replace
C:\Users\%username%\
by
%USERPROFILE%\
and averything is ok.
( by the way, if you have also an JRE_HOME , change it too )

There is an SDK Manager Icon in the top right of Android Studio between the AVD manager icon and the magnifying glass. Click it.
You get a modal that shows you are in System Settings -> Android SDK n the left menu. In the middle area there is an SDK Tools tab so click it.
Check off the box that says "Android SDK Command-line Tools (latest)" and click Apply. It will install it (about 105M). Now run flutter doctor --android-licenses and say yes to everything. The error should be gone.
Use flutter_console instead of CMD
flutter doctor --android-licenses
This worked for me:
open Android Studio's SDK Manager
go to the Android SDK tab
under SDK Tools, uncheck Hide Obsolete Packages
install Android SDK Tools (Obsolete)
SOLUTION: None of the above works when setting up a Windows 10 Flutter 1.17.1 environment for mobile development. The quickest and easiest solve is to download android-studio-ide-193.6514223-windows (Android 4.0) from https://developer.android.com/studio/archive.
Download Android 4.0
Install Command
Line Tools in SDK Settings
Reboot Open Command Prompt
flutter doctor -v
You must install Android SDK Command-line Tool(Latest).
Go to SDK Manager in android studio, in tab SDK Tools, check in Android SDK Command-line Tool(Latest) and then click "apply".
On Windows:
open cmd and run:
android update sdk
After that run flutter doctor again
in terminal :
flutter update
flutter doctor --android-licenses
accept all terms by y
Uninstall Android Studio or the Android SDK. Reinstall it.

I've been trying to get my Flutter project to run after upgrading it to 2.10.4 and it's been a headache from the start. The project runs fine on a browser, but I'm having difficulty running on an Android emulator. I think I'm at the last hurdle, but I'm stumped right now. I'm receiving this error when running on VS Code:

I have no clue where to go from here. Any help would be greatly appreciated here. Thank you in advance.
It appears that you have two sets of Android Studio and Android SDK.
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
• Android SDK at C:\Program Files (x86)\Android\android-sdk <--- 1
...
• ANDROID_HOME = C:\Users\reff1\AppData\Local\Android\Sdk <--- 2
[√] Android Studio (version 2021.1) <--- 1
• Android Studio at D:\AndroidStudio
...
[!] Android Studio (version 4.1) <--- 2
• Android Studio at D:\Programs\AndroidStudio
Android Studio version 4.1 is a bit older so I guess you installed it in the past and forgot about it.
Also, it is not normal (or up-to-date) to have Android SDK placed under Program Files.
This is the direct cause of the error. In Windows, writing files under Program Files requires administrator privileges.
Your system is possibly confused because you have a mixed environment with an SDK that requires administrator privileges and one that does not.
My advice is to first uninstall all of them.
Before you begin, find out where the Android Studio configuration files are stored and backup them.
It is documented in here.
Now, completely uninstall all versions of Android Studio and Android SDK, manually delete all environment variables related to Android if any, manually delete (and backup) all configuration files if the uninstaller did not, then make sure all four directories above are empty.
Next, install the latest version of Android Studio and install the Android SDK via Android Studio. At this point, make sure that the installation directory is not under Program Files or Program Files (x86). If it is, then something in the older version is still there and is doing bad things so you have to restart from the first step.
Finally, run flutter clean (just to be sure), then flutter doctor to make sure only one of each is detected.
In android studio update your sdk 30
Unable to determine bundled Java version.
• Try updating or re-installing Android Studio
See in your error in flutter doctor
Change the ownership of Android SDK:
sudo chown -R $(whoami) $ANDROID_HOME
For this issue : Android license status unknown.
Type in command prompt
flutter doctor --android-licenses
Type Yes/y/Y to accept licenses
Maybe it's an emulator specific issue, did you try to run it on a real device?
Regarding the android license issue you are getting, I guess that the system is not recognizing JAVA or it needs to be updated so please check that.
Also make sure that the emulator itself is updated and not only the android SDK, go to SDK manager and check all the dashed components:
If this didn't work, delete the emulator and create a new one, and if that didn't help, delete all instances of android studio as I see 2 on your system that might conflict the SDK path.
I already have Android Studio installed and tried installing Flutter. After following the instructions, I have encountered a problem. When I run
flutter doctor -v
It returns

I tried connecting my device too and it didn't recognize, even after enabling USB debugging. I also tried reinstalling Android Studio. I think the issue lies with the missing 'aapt' since it's not on any folder when i manually looked for it but Android SDK file not found: C:\Users\%User%\AppData\Local\Android\sdk\build-tools\30.0.2\aapt tells me it should be there.
Thank you for the help!
try this...
open cmd or terminal and run below command
flutter config --android-sdk <path-to-your-android-sdk-path>
hope this will work
I had the same problem today :
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3) X Android SDK file not found: C:\Users\admin\AppData\Local\Android\Sdk\build-tools\30.0.3\aapt.
I fixed it by deleting the two most recent folders in C:\...\build-tools\ which do not contain aapt.exe -> 30.0.2 and 30.0.3 (This deleted folders only contained a folder named .installer).
This answer inspired me : https://stackoverflow.com/a/56995320/13170425
flutter config --android-sdk
run this command and run flutter doctor again this should help you
That's not a big deal. You install the Android SDK and 1 notice that the device is not connected only. You can install the android SDK from the link below:
https://developer.android.com/studio#downloads
I had the same issue
Android SDK file not found: C:\Users\Admin\AppData\Local\Android\Sdk\build-tools\31.0.0\aapt.
I had already tried other solutions but this worked for me . In SDK Manager , go to SDK tools , and check the checkbox "Show the various packages" and uncheck "Hide obsolete packages"
Now under Android SDK Build-tools 31 , install 31.0.0 and apply
Under Android SDK Command-line tools (latest), install Android SDK Command-line tools (obsolete)
This worked for me , hope it works for you too !
Reinstalling the sdk 30.0.2 from sdk manager in android studio(Tools->sdk tools->(tick show package details)) fixes the problem.
I had the same problem today. In my problem, can not find 32 aapt., I had try many:
flutter config --android-sdk [path]
uninstall 32 and install again
install low version like 31（30）
and so on
still not work until:
uninstall 32
remove folder 32 which need aapt.
So today I freshly installed android studio for flutter. I followed every step given on the flutter website. Yet I came across multiple issues at different point of time.

1. Tried to run the app, the Gradle task assembleDebug Kept On loading and i found out i need to install Android API 28, That being done now came the

again wandering on the internet i found out that this error might have to deal with it. so again the same solution came up : install the 'Android SDK Tools (Obsolete).'
running upon flutter doctor --android-licenses
it showed that sdkmanager is missing. so i manually downloaded the commandtoollines from the android studio website(this one had 'sdkmanager.bat' which was missing in the orginal one;, and pasted it to the required folder. Now I am getting a new error yay!!!!!.
C:\Users\DELL>flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
C:\Users\DELL\AppData\Local\Android\sdk\tools\bin\sdkmanager --update
So i would highly appreciate someone if anyone could help me out.
In Android Studio, there is a tab at the bottom of the screen that says Terminal,
This is where this tab is located at the bottom of the screen
Copy and paste the following statement into the terminal and run it
C:\Users\DELL\AppData\Local\Android\sdk\tools\bin\sdkmanager --update
Hopefully after the update is done, things should go alright. Otherwise, you might need to run some other statements and check what else is missing. Installing Android studio may be a bit tedious because it depends on a lot of factors to run properly.
Tried everything i had found(github issues, SO questions) . Also tried to re-install Android SDK(29) from Android Studio.

If same error occur, open Android Studio, go to Settings and navigate to "Appearance & Behavior > System Settings > Android SDK", then at the top of the window and to the right of Android SDK Location, click on Edit, and from the window that opens, update your current SDK Manager and install the latest API if not already installed; once everything is updated or installed in this windows, close the Android Studio and close the command prompt.
Open a new command prompt and run "flutter doctor" again (without the quotation marks). Follow the software instructions to accept all Android Licenses.
Follow these steps
1. Open the Android Studio SDK Manager
2. Android SDK Command-line Tools (latest)
Install this one.

I've tried downloading the SDK Tools Package and even Installed Android Studio
and added it to PATH, but was unable to resolve the issue.
The current Android installation sits in a directory called C:\NVPACK, and although I do remember fiddling with it, I don't remember which program installed it. I'm considering removing it. Any help would be greatly appreciated.
Flutter provide command to update our Android SDK path:
Use flutter config --android-sdk <path-to-your-android-sdk-path>
Or just add a variable ANDROID_HOME with your sdk location in user variables
It turns out that I had NVIDIA CodeWorks installed. I believe it was part of my VS2017 installation options. I've removed it and modified my ANDROID_HOME Environment Variable and removed all of the variables associated with the NVPACK folder. (thanks to everyone (1) who helped me offsite!)
You have to set ANDROID_HOME variable to SDK.
create a new variable by the name and set it to the installation directory.
make sure SDK is not below 2 subfolders from c drive or any windows root drive.
Open Android Studio.
Click on Tools go to Sdk manager.
Then click on SDK tools.
Unchecked Hide Obsolete Packages then Check Android SDK Tools.
Then Tools will be install after that you can set the path and check the connectivity.
Your problem will resolve.
Go into C:\Users\asus\AppData\Local\Android\sdk, double cliclk on sdk mannager.exe and update all packages.
It will take around 10 minutes to update which also depends on your internet speed.
You need to install the command-line tools inside Android studio, as explained here:
Flutter doctor error - Android sdkmanager tool not found. Windows
For Mac Users use:
flutter config --android-sdk /Users/<your-user>/Library/Android/sdk
I have installed Flutter with Android Studio many times. And I found most of the installation errors were because of poor network connection. When I use fast internet service, Flutter Environment was set up within an hour without any issue.
Internet speed is very important while Flutter, Android Studio, and SDK installation.
Best,
Ahmed I.
1- Activate Command-line Tools and download it as in this picture
2- Add Android SDK path to your system environment variables.
this link would help you..
