Android sdkmanager tool not found

[![enter image description here][1]][1]I newly started using Ubuntu 18.0 LTS this week, switching from Windows, and wanted to install Android Studio and Flutter back. I followed all the steps as said to install Android Studio and it is working fine with all the SDKs. However, when I wanted to install Flutter, it gives exception:

Doctor summary (to see all details, run flutter doctor -v):
Unhandled exception:
Exception: Android sdkmanager tool not found (/usr/lib/android-sdk/tools/bin/sdkmanager).

for detailed instructions.
Ask for the stacktrace if you need it.

The closest issue I could find was:

but I couldn't really understand how to work the instructions. I might need you to be really clear in the instructions because I'm new to the linux platform.

I had this issue when I installed on Ubuntu. You need to set env variable ANDROID_HOME to the path you installed the android sdk for flutter to work.

So assuming you installed the SDK in your home directory, open a terminal and issue this command

ANDROID_HOME=~/Android-SDK flutter doctor
If that worked, then add the env variable to your profile to make it persistent, by adding

export ANDROID_HOME=~/Android-SDK
to your ~/.profile script, then relogin to Ubuntu.

Obviously if you installed the android sdk in a different directory, you just need to replace ~/ with the directory, so for example if you installed the sdk to /opt, then the command would be
ANDROID_HOME=/opt/Android-SDK flutter doctor

Having checked my android sdk + flutter setup, I also ended up adding the following to my path

~/Android-SDK/platform-tools

You can test this before messing with your profile, by the following command in a terminal

PATH=$PATH:~/Android-SDK/platform-tools ANDROID_HOME=~/Android-SDK flutter doctor
And again change ~/Android-SDK to wherever you installed the android SDK. If it works, change your profile accordingly and relogin to Ubuntu.

I had this issue after installed on my KUbuntu.

You need to open **AndroidStudio** then go to **Tools** -> **SDK Manager** then go to **SDK Tools** tab, uncheck the option `Hide Obsolete Packages`

You will see the option of **Android SDK Tools (Obsolete)**, check the option and continue the process download and installation.

I'm using Manjaro Linux. After set my `ANDROID_HOME` and install Android **SDK Command-line tools (latest**) from Android Studio.

And ran:

[flutter doctor --android-licenses][1]


$ mkdir ~/Android/Sdk/tools/bin
And created a link to the real path

$ ln -s ~/Android/Sdk/cmdline-tools/latest/bin/sdkmanager ~/Android/Sdk/tools/bin/sdkmanager

Ran again and accept all

$ flutter doctor --android-licenses

[flutter doctor][2]

[2]:

If you come across this error when accepting SDK licenses.
```
➜ ~ flutter doctor --android-licenses
Android sdkmanager not found. Update to the latest Android SDK and ensure that the cmdline-tools are installed
to resolve this
```

the structure of the initial android-sdk was :
```
android-sdk
├── build-tools
│   ├── 29.0.3 -> debian
│   └── debian
│   └── lib
├── cmdline-tools
│   ├── tools
│   │   ├── bin
```
and the way i was able to configure android licenses was to change the structure of the android-sdk directory by changing 'tools' to 'latest'

```
android-sdk
├── build-tools
│   ├── 29.0.3 -> debian
│   └── debian
│   └── lib
├── cmdline-tools
│   ├── latest
│   │   ├── bin
| | |
```

I'm always puzzled why an installation package shouldn't contain all necessary dependencies but cause trouble (perhaps fun) to so many people?

Anyway, I'd like to add something to the [zmofsx][1] [solution][2] because, for me, the solution didn't fix the problem completely, and I had to do a few more steps described below.

Hope those may help someone in troubleshooting.

So after the steps described [above][2], I did the following in the console:

flutter doctor --android-licenses

Hit Y to show all the licences and Y to each of them. Then

flutter doctor

And this is my console output:

Then tested the result:

mkdir flutter_example
cd flutter_example
flutter create .
flutter run -d linux

And got the app running:

use the tool of config from Flutter
```bash
flutter config --android-sdk ~/Android/Sdk/
flutter config --android-studio-dir ~/android-studio/
```
after accept licences
`flutter doctor --android-licenses `

To fix the Android sdkmanager not found warning:

1. Open Android Studio
2. From the top toolbar, select **Tools > SDK Manager**.
3. Select the **SDK Tools tab**, with a blue underline.
4. Uncheck 'Hide Obsolete Packages'.
5. Tick `Android SDK Command-line Tools (latest)`.

6. Click **Ok**

For those using pop_os 22 and have installed the android studio using flatpak
the problem is that the android studio is isolated so you need to config the path for android-sdk and android-studio-dir

flutter config --android-sdk ~/Android/Sdk
flutter config -android-studio-dir path/android-studio

for pop_os installed from shop you'll find it here /home/<username>/.local/share/flatpak/app/com.google.AndroidStudio/current/active/files/extra/android-studio

then you will run `flutter doctor --android-licenses` and accepts all licenses so now `flutter doctor` will not show a error.
