[Flutter] flutter doctor - unable to locate android sdk on ubuntu

Running flutter doctor -v on my ubuntu 24.04.1 installation reports these problems

• Unable to locate Android SDK
• No valid Android SDK platforms found in /usr/local/android-sdk/platforms. Directory was empty.
• Unable to determine Android Studio version

What did i try


Running ./sdkmanager --list_installed returned

$ cd /usr/local/android-sdk/cmdline-tools/latest/bin
$ ./sdkmanager --list_installed
[=======================================] 100% Fetch remote repository...
Installed packages:
Path | Version | Description | Location
------- | ------- | ------- | -------
platform-tools | 35.0.2 | Android SDK Platform-Tools 35.0.2 | platform-tools



So i ran also

$ cd /usr/local/android-sdk/cmdline-tools/latest/bin
$ sudo ./sdkmanager "emulator"
$ sudo ./sdkmanager "build-tools;35.0.0"
$ sudo ./sdkmanager "cmdline-tools;latest"


Now ./sdkmanager --list_installed returns

/usr/local/android-sdk/cmdline-tools/latest/bin$ ./sdkmanager --list_installed
[=======================================] 100% Fetch remote repository...
Installed packages:
Path | Version | Description | Location
------- | ------- | ------- | -------
build-tools;35.0.0| 35.0.0 | SDK Build-Tools 35 | build-tools/35.0.0
cmdline-tools;latest| 16.0 | SDK Command-line Tools | cmdline-tools/latest
emulator | 35.2.10 | Emulator | emulator
platform-tools | 35.0.2 | SDK Platform-Tools 35.0.2 | platform-tools


The last lines of my ~/.bashrc are

export ANDROID_HOME=/usr/local/android-sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools


Running tree -dL 2 /usr/local/android-sdk returns

/usr/local/android-sdk
├── build-tools
│ └── 35.0.0
├── cmdline-tools
│ └── latest
├── emulator
│ ├── bin64
│ ├── include
│ ├── lib
│ ├── lib64
│ ├── qemu
│ └── resources
├── licenses
└── platform-tools
└── lib64


Still the same problem


This is the output of flutter doctor -v
