Are you saying "tns create test --js" then "tns run android" will fail with the above error? Or does the flavor matter, any other changes you did? Can you do a "tns info" to list versions?

[JimLynchCodes]

Hi @NathanaelA

Yes, it breaks for me.

I just reinstalled tns cli, created a new project with "tns create test --js", went into the new test folder and ran "tns run android" (choosing "Configure for Local Builds"

When I say "n" to all the questions I get this output:

Restart the terminal or run `source ~/.bash_profile` to use them.

✔ Your adb from the Android SDK is correctly installed.

Error: 
  homebrew-core is a shallow clone.
To `brew update`, first run:
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
This command may take a few minutes to run due to the large size of the repository.
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!
Warning: Cask 'android-sdk' is already installed.

To re-install android-sdk, run:
  brew reinstall android-sdk

^ What am I supposed to do here?

It would be really nice if there was a nativescript-focused guide on setting up your environment for android development because I've been trying to get this working unsuccessfully for months... 😅

[rigor789]

@JimLynchCodes I have a draft of the setup guide rewritten for the new docs, perhaps you can try these steps: https://gist.github.com/rigor789/7829f09b5a903fdf31799b65b902c52e

Your issue seems to be an invalid or missing ANDROID_HOME environment variable.

[JimLynchCodes]

Thanks @rigor789

I'm on a mac so the steps are a bit different... I just reinstalled android studio, but when I do ns doctor it fails on the android parts:

~ ★ ns doctor
✔ Getting environment information 

TIP: To avoid setting up the necessary environment variables, you can use the Homebrew package manager to install the Android SDK and its dependencies.

There seem to be issues with your configuration.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 7.1.2 version and is up to date.
✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ The Android SDK is installed.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Xcode is installed and is configured properly.
✔ xcodeproj is installed and is configured properly.
✔ CocoaPods are installed.
✔ CocoaPods update is not required.
✔ CocoaPods are configured properly.
✔ Your current CocoaPods version is newer than 1.0.0.
✔ Python installed and configured correctly.
✔ The Python 'six' package is found.
✔ Xcode version 12.4.0 satisfies minimum required version 10.
✖ WARNING: adb from the Android SDK is not installed or is not configured properly.  
 For Android-related operations, the NativeScript CLI will use a built-in version of adb.
To avoid possible issues with the native Android emulator, Genymotion or connected
Android devices, verify that you have installed the latest Android SDK and
its dependencies as described in http://developer.android.com/sdk/index.html#Requirements 

✖ Cannot find a compatible Android SDK for compilation. To be able to build for Android, install Android SDK 28 or later. 
 Run `$ sdkmanager` to manage your Android SDK versions. 

✖ You need to have the Android SDK Build-tools installed on your system. You can install any version in the following range: '>=23 <=30'. 
 Run `$ sdkmanager` from your command-line to install required `Android Build Tools`. In case you already have them installed, make sure `ANDROID_HOME` environment variable is set correctly. 

Your environment is not configured properly and you will not be able to execute local builds.
Select "Sync to Playground" to enjoy NativeScript without any local setup. All you need is a couple of companion apps installed on your devices.
Select "Configure for Local Builds" to run the setup script and automatically configure your environment for local builds.
Select "Skip Step and Configure Manually" to disregard this option and install any required components manually.

@NathanaelA do you have any idea what I should do here?

or anyone else? 😥

[rigor789]

@JimLynchCodes fix your environment variables & android sdk:

Make sure to have ANDROID_HOME set and pointing to a valid sdk
Make sure to have build-tools & api levels installed (all managed through Android Studio - just tick the boxes under sdk manager)
Make sure to have your PATH set to include your sdk binaries.

The exact steps to get these fixed depend on your system, how you set some things up previously, so it's generally difficult to give concrete steps.

I added the macOS steps for Android to my gist: https://gist.github.com/rigor789/7829f09b5a903fdf31799b65b902c52e#macos--android (some steps are same as windows, refer to the windows parts too, especially for the Android SDK setup & Android Studio), but again - your steps could be different depending how you set up your stuff so far.

[JimLynchCodes]

thanks @rigor789

I've gone through your guide, but sadly it doesn't work for me...

Possibly I need to do something from the missing "Setting up the Android development environment" section?

I have:

• installed android studio

• installed openjdk 8

• set my ANDROID_HOME to ``

• set my path to have ``

nvm use v14
Now using node v14.15.4 (npm v6.14.10)

ANDROID_HOME=/usr/local/share/android-sdk
ANDROID_SDK_ROOT=/usr/local/share/android-sdk

JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

PATH=/Users/jim/.sdkman/candidates/java/current/bin:/Users/jim/.sdkman/candidates/gradle/current/bin:/Users/jim/perl5/perlbrew/bin:/Users/jim/google-cloud-sdk/bin:/Users/jim/.cargo/bin:/Users/jim/.nvm/versions/node/v14.15.4/bin:/usr/local/mongodb/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/opt/local/sbin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Ballerina/bin:/Users/jim/go/bin:/usr/local/go/bin

what else do I need to do here to get "The Android SDK is not installed or is not configured properly. "??

[JimLynchCodes]

@rigor789 why did you close my issue when it hasn't been solved? should I open a new one? 🤔

[JimLynchCodes]

bump! 🙃

[JimLynchCodes]

hey @rigor789 @NathanaelA

Like I mentioned, I added the environment variables exactly as the guide stated... it did not change the cli output at all.

What else should I try? 🤔

[JimLynchCodes]

cli kept adding the wrong paths into my .bash_profile

when I add these to the bottom of my .bash_profile it works!

export ANDROID_HOME=~/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/platform-tools

OMFG YES!!!!!
