I can't run application because there is no devices on the list.
I tried to create AVD and connect real device. I have installed curl, Android SDK path was set, flutter licenses were accepted. I have Ubuntu 16.04.4
Output of flutter run --verbose in projects directory :
flutter: command not found
I have flutter path:
$ export PATH=/home/joe/flutter/bin:$PATH
$ echo $PATH
/home/joe/flutter/bin:home/joe/flutter/bin:home/joe/flutter/bin:/home/joe/bin:/home/joe/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
Now I put path's to .bashrc and run source ~/.bashrc, did I put path's correct way ?
# set PATH so it includes user's private bin directories
export PATH=/home/joe/flutter/bin:$PATH
export ANDROID_HOME=$HOME/Android/SDK
export PATH=$PATH:$ANDROID_HOME/tools
After adding path's to .bashrc I run flutter doctor:
$ /home/joe/flutter/bin/flutter doctor

Can be easily fixed by setting project SDK to latest Android API.
Go to File
Project Structure
Under Project-SDK select the latest SDK installed(Example:- Android API 29 Platform).
You have to set an Environment variable.
You can check it here for Flutter SDK setup with Android Studio

Probably because is missing /sdk
Try to change export ANDROID_SDK_ROOT="$HOME/android"
to export ANDROID_SDK_ROOT="$HOME/android/sdk"
if not work, try to check the full path to platform-tools
run which adb
$HOME/android/sdk/platform-tools/adb
flutter can't recognize the sdk unless you install the rest of the components
the following worked
# 30 is my physical device compatible version
sdkmanager --install "build-tools;30.0.2"
sdkmanager --install "platforms;android-30"

Can anyone help me with this issue please.
I found the solution by using this following command:
sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev
and
flutter config --enable-linux-desktop
you must install ninja.
sudo pacman -S ninja or sudo apt-get install ninja.
I installed android-sdk and flutter-git on Manjaro with AUR. I set and exported the vars ANDROID_HOME and ANDROID_SDK_ROOT === /opt/android-sdk.
However, when I run flutter doctor the android sdk seems to not been recognized.
I will use flutter on vs-code.
How can I set up all this correctly?
What I did:
export ANDROID_HOME=/opt/android-sdk/
export ANDROID_SDK_ROOT=/opt/android-sdk/

Run Android Studio, create a new project and run it
The main problem was the jdk version, I was using version 10. The recommend one is version 8 because the java.se.ee class.
Steps
Use this command or use the "Add/Remove Softare"
yaourt -S flutter-bin android-sdk android-sdk-platform-tools
Choose the open jdk 8 and run all commands below:
sudo chown -R $USER:$USER /opt/*
flutter precache && flutter doctor
If "Android Licenses are unkown", run flutter doctor --android-licenses
These steps will automatically set all env vars such as "ANDROID_HOME" but if you get any error, export them using the path to android-sdk, that will be /opt/android-sdk/

The line following error is strange.
[!] Android toolchain - develop for Android devices (Android SDK
version 29.0.3)
✗ Android SDK file not found: adb.
Android SDK is installed
Platform tools are installed
If I run adb devices on my terminal, everything works fine and my device appears.
Any idea on how to fix this?
So I fixed in a very strange way:
Seems like some new version of Android SDK moved adb from /sdk/platform-tools to /sdk/platform-tools/platform-tools
To fix, I've only moved adb from /sdk/platform-tools/platform-tools to /sdk/platform-tools and now it's working.
Starting with the less complex fix;
Open vscode, click on the extension tab then search and install flutter extension.
Open the App Store search and install Xcode. It takes a very long time to complete. Clearly your installation is not complete.
If you are sure you have android SDK downloaded, then use the following command to provide the path the android studio. flutter config --android-sdk <path-to-your-android-sdk-path>
. Else you can use android studio to download the required Android SDK. See location in picture
Installing Xcode in the App store will install cocaopods. Then try flutter doctor -v and everything will be good.
NOTE: you don't need adb in mac for flutter to compile on android. downloading an Android SDK will install qemu. You will also notice some significate process load while running an Android emulator because of the running qemu process since it is not very optimized fro mac. But that is not an issue you will get use to or just use a real android device. Install Xcode will install all Iphones simulators.
i can't update the sdk tools, i don't know why, if use this command "sdkmanager --update" or "android update sdk" it will give me error like this title :
Warning: An error occured during installation: Failed to move away or delete existing target file: C:\androidSDK\sdk\tools
big thanks if you can help me!
1) Rename C:\Users\%username%\AppData\Local\Android\Sdk\tools folder to tool
2) Navigate to cd C:\Users\%username%\AppData\Local\Android\Sdk\tool\bin in cmd
3) And run sdkmanager --update --verbose, will create a new folder tools
4) Run flutter doctor --android-licenses
5) Then Accept the android licenses by clicking y
6) flutter doctor command will show the following:

Here is how i solved this problem:
First, I renamed AndroidSDK\tools to AndroidSDK\tool.
Then, I set the windows' environment variable Path from AndroidSDK\tools to AndroidSDK\tool (maybe not necessary)
Run sdkmanager --update in tool\bin .
Ignore the warning and wait until the update is done.
There will be a new folder named tools in AndroidSDK.
Copy all the files in tools folder and paste them to tool folder.
Overlay all the files that which has the same name in tool folder.
Finally,delete tools folder and rename tool to tools.
Problem solved.
