Is it possible to use NativeScript?

General

Hello there!

I’d like to develop a mobile app using NativeScript. I installed the CLI through an npm command, set up a new project, but when I try to launch it in Android using ns run android, it fails because it needs an Android emulator.

Is it possible to make it work with IDX?

Thank you c:

The output :

blank-test-7031061:~/blank-test/example-app{master}$ ns run android

Hi @zonetecde - that is interesting! With our Flutter project template, the workspace has all of the dependencies configured for building and previewing apps using the Android emulator.

I am thinking out loud here, but have you tried running this command inside a Flutter workspace? The Android emulator would be present there, so this error may not appear there.

Thanks,
Kirupa

Just tried it, but sadly, it does not work, and I got the exact same output. Good idea though :slight_smile: !

Flutter workspace required

You have to set ANDROID_HOME as stated in the documents
(Setting up Linux for NativeScript | NativeScript)

export ANDROID_HOME=/opt/android

To make this permanent add the follow snippet to dev.nix

  env = {
    ANDROID_HOME=/opt/android;
  };

After rebuilding the environment, you can ensure that it works by running this command:

ns doctor android

WARNING: DO NOT SET PATH IN nix.dev, DUE TO A BUG, IT MAY LEAD YOUR WORKSPACE TO BE PERMENTANLY BROKEN

Sorry for reopening this thread. I tried this too and it worked up to some point. I tried changing the command in .nix file to use ns run android, when having the environment and keeping the manager as flutter, but I’m getting an error saying “ns ENOENT”.

I can remove that and run the command manually while having manager=“flutter” and it shows a green loader at top.

In Both cases I can work with the emulator, but it kinda annoys me and I would like the project to run ns run android so I can keep coding right away without having to run the command manually.

Awesome! Can you submit this template on GitHub - project-idx/community-templates: A library of templates to get you started faster and explore tools, frameworks, and runtimes.?

Can I somehow get the required files from the flutter project I tweaked? I think that might make it easier to get a template.
