Flutter doctor wont accept android SDKs

[Martin Lyne]

Hi,

 I'm trying to get flutter working for the first time but it seems that I don't have a valid sdk version (or something?)

From flutter doctor -v

[✓] Flutter (Channel stable, v1.0.0, on Linux, locale en_US.utf8)
    • Flutter version 1.0.0 at /home/vagrant/development/flutter
    • Framework revision 5391447fae (2 weeks ago), 2018-11-29 19:41:26 -0800
    • Engine revision 7375a0f414
    • Dart version 2.1.0 (build 2.1.0-dev.9.4 f9ebf21297)

 

[!] Android toolchain - develop for Android devices

    • Android SDK at /home/vagrant/development/android

    • Android NDK location not configured (optional; useful for native profiling support)

    ✗ No valid Android SDK platforms found in /home/vagrant/development/android/platforms.

      Candidates were:

        - android-23

        - android-27

        - android-28

[!] Android Studio (not installed)
    • Android Studio not found; download from https://developer.android.com/studio/index.html
      (or visit https://flutter.io/setup/#android-setup for detailed instructions).
[!] Connected device
    ! No devices available

 

This is my second attempt with a fresh VM. I'm trying to do it all headless (no Android Studio) installing android CLI tools and flutter via the zipped files.

As you can see I tried to use sdkmanager to install multiple versions of the sdk, to no avail. 

I don't know what to try next, any help greatly appreciated.

Hi ! Martin , This is what worked for me : I installed android studio (latest version) , with SDK updated latest version.

I downloaded Flutter SDK and put it somewhere in my OS. I set all flutter required package installations

after that only after that I installed flutter and dart plugin under android studio3.

When done with all thos steps, I started again android studio find out New Project Flutter under main android studio entrance. It asked for flutter sdk path (I set that) 

and now I'm keep learning / teaching myself flutter.

Find in attachments some helpfull pictures.

And tell me if you're right in your side.

Obvious response: install the AndroidStudio. Assuming you have a good reason to not do that, what is actually in /home/vagrant/development/android/platforms

Thanks, I don't have a graphical UI on my VMs - everything is CLI, if Flutter requires that then I don't think it's for my project. Thanks for your help!

You install Android Studio in order to get the tools, toolchains, etc.  You don't need to actually run the IDE - I never do. I could, but I'm a CLI guy too.

Before Studio you could download the sdk separately. Now Studio contains everything. Er, I guess you might need a GUI to run the bit where you select the API support you want etc. But Studio does include a bunch of CLI utilities that may allow you to do that without a GUI.

You making it right, but you still missing build-tools.

try 

sdkmanager'build-tools;{VERSION_YOU_NEED_OR_LATEST}'

platforms and platforms tools are not enough. run sdkmanager --list, there you can see the list of installed packages.

flutter requirements are:

- platforms;android-{AT_LEAST_VERSION_27}

- platform-tools

- tools (you have it already)

- build-tools
