D:\DANI\vscode\NativeScriptAngularExample>tns info
✔ Getting NativeScript components versions information...
✔ Component nativescript has 8.0.1 version and is up to date.
✔ Component @nativescript/core has 8.0.3 version and is up to date.
✖ Component @nativescript/ios is not installed.
✔ Component @nativescript/android has ~8.0.0 version and is up to date.
Describe the bug
When I run the command ns run android to launch the app in a virtual device, the app is built and installed correctly, but it shows the error in console:
Unable to apply changes on device: emulator-5554. Error is: Invalid Version: ~8.0.0.
I have checked that the app is installed in the virtual device and if I open it manually it works properly, it seems the problem only affects to hot-reload of changes.


See complete log of run command:
D:\DANI\vscode\NativeScriptAngularExample>ns run android

To Reproduce
- Install NativeScript in your computer with npm
- Create a new sample project using the CLI with the Angular template
- Setup the environment as per documentation (ANDROID_HOME, Path)
- Install Android SDK >= 28 and create a virtual device for that version
- Launch virtual device and run the NativeScript application using the CLI
Expected behavior
The expected behaviour would be to not see any errors in console and have hot-reaload of changes in the virtual device.
Sample project
I'm following the NativeScript Tutorial, the project has been created with the command ns create NativeScriptAngularExample --angular and there are no changes in the project except adding the dev dependency "@nativescript/android": "~8.0.0" as per documentation.
https://docs.nativescript.org/environment-setup.html#windows-android
I have checked my setup is correct by running the doctor.
See complete log of doctor command:
D:\DANI\vscode\NativeScriptAngularExample>ns doctor android
✔ Getting environment information
No issues were detected.
✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ The Android SDK is installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Local builds for iOS can be executed only on a macOS system. To build for iOS on a different operating system, you can use the NativeScript cloud infrastructure.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 8.0.1 version and is up to date.
✔ Component @nativescript/core has 8.0.3 version and is up to date.
✔ Component @nativescript/android has ~8.0.0 version and is up to date.

调研方向
首先,使用 Angular 示例项目和文档中记录的 @nativescript/android 版本 ~8.0.0 重现 ns run android。跟踪 webpack 编译后的 Android 热重载路径,重点关注该版本在哪里被解析。完成的标准是:更改能够应用而不会出现 Invalid Version 错误,并且热重载能在模拟器上正常工作。
