Flutter can't find android studio

[ArthurRbn]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

My configuration:

• Ubuntu 22.04.3 LTS
• Flutter installed via snap (Flutter (Channel stable, 3.16.0, on Ubuntu 22.04.3 LTS 6.2.0-37-generic, locale en_US.UTF-8))
• Android studio installed from jetbrains toolbox (Android Studio Giraffe 2022.3.1 Patch 4)
• SDK: Android 14.0 "UpsideDownCake" API Level 34 Revision 2
• AvdId Pixel_3a_API_34_extension_level_7_x86_64

I want to be able to run flutter run -d {android device} with my simulated phone as the target.

I have also configured flutter like so:
flutter config --android-sdk="$HOME/Android/Sdk"
flutter config --android-studio-dir="/home/arthur/.local/share/JetBrains/Toolbox/apps/android-studio"

The command flutter devices returns this:
Found 2 connected devices:
Linux (desktop) • linux • linux-x64 • Ubuntu 22.04.3 LTS 6.2.0-37-generic
Chrome (web) • chrome • web-javascript • Google Chrome 119.0.6045.159

The commands flutter emulators and flutter emulators --create return this:
Unable to find any emulator sources. Please ensure you have some
Android AVD images available.

Actual results

Currently flutter doctor doesn't detect android on my desktop as the android toolchain isn't displayed in flutter doctor.
I am unable to run my flutter app with my android simulated phone as the target and I don't find any other solution on internet to fix this configuration problem.

Unable to find any emulator sources. Please ensure you have some
Android AVD images available.

Try installing AVD images:

sdkmanager --install 'system-images;android-34;google_apis;x86_64'

The sdkmanager binary should be in $HOME/Android/Sdk/cmdline-tools/latest/bin/sdkmanager.

[ArthurRbn]

Thanks for your quick response !
I was in fact missing the sdkmanager. I installed it via Android studio and ran you command without problem. That said, flutter doctor -v output hasn't changed and there is no mention of android toolchain in it. What I have trouble to understand is that most people still have android toolchain showing up in the flutter doctor output even when they have installation problems. For me it's like flutter is completely ignoring it.
Also flutter emulators and flutter emulators --create output is still the same:

Unable to find any emulator sources. Please ensure you have some
Android AVD images available

[bartekpacia]

I think you have Android SDK set up incorrectly. Do you have ANDROID_HOME env var set? Android Studio isn't really needed for Android development, all you need for flutter build apk and flutter run is to have Android command line tools.

E.g. here is how I configure Android SDK in my shell startup file. You likely have Android SDK at different location than ~/androidsdk, but that's the only change you'd have to make. It should help.

I also wrote a blog post on how to configure Android SDK "the right way" (IMHO), you might find it helpful: https://garden.pacia.tech/suckless-androidsdk-setup

@ArthurRbn I thought the issue was caused by your android-studio being under a hidden directory but it doesn't seem the case as I can see a similar path here #121501 (comment) (.local/share/JetBrains/Toolbox/apps/).

Please check @bartekpacia's blog post if it helps. Also, could you share the output of flutter emulators -v?

@bartekpacia Great article, I think you could share it here as well: #71368

[ArthurRbn]

Hi !

Thank you again for you answers, I will try @bartekpacia 's shell startup file and if it doesn't work I will try his blog post about how to setup Android SDK properly. Will update soon.

Here is my output of flutter emulators -v:

@ArthurRbn I see you are using Flutter which is installed through snap (it could be the cause, please see an old related issue #74538). You can try using Flutter installation manually to see if it works.

[ArthurRbn]

Hi @huycozy, it worked !

I spent last night installing tools, exporting environment variables, upgrading my java version etc... Nothing changed.
Today I just reinstalled flutter manually and it worked instantly. Flutter doctor tells me that the android toolchain is correctly setup and it detects my emulators. When I start my emulator it is correctly listed in the devices and I can run my app with flutter run -d emulator-5554.

If this can help anyone I installed flutter manually like described here and this is my ~.bashrc:

export ANDROID_HOME="/home/${USER}/Android/Sdk"
export PATH="bin:$PATH:$ANDROID_STUDIO/tools:$ANDROID_HOME/tools/bin:$ANDROID_HOME/platform-tools:$ANDROID_HOME/cmdline-tools/latest/bin:$ANDROID_HOME/emulator:/home/${USER}/flutter/bin"

Thank you guys for helping me !
