Nativescript: tns device does not show emulator. ADB shows device
If the tns device
command does not show the emulator while the adb devices
command does, it could indicate an issue with the NativeScript CLI or the device detection mechanism. Here are a few steps you can take to troubleshoot the problem:
Restart NativeScript CLI: Sometimes, the NativeScript CLI may not detect emulators properly due to caching or other issues. Try restarting the NativeScript CLI by running the following command:
tns doctor
This command checks the environment and restarts the CLI components. After that, try running
tns device
again to see if the emulator is detected.Verify ADB installation: Ensure that the Android Debug Bridge (ADB) is installed correctly and accessible from the command line. Run the following command to check the ADB version:
adb version
If ADB is not recognized or there are any issues, verify that the Android SDK is installed and the ADB executable is added to the system's
PATH
environment variable.Check the emulator's state: Ensure that the emulator is fully booted and in a usable state. Launch the emulator from the Android Virtual Device (AVD) Manager or Android Studio and wait for it to finish loading. It's also a good idea to test the emulator with other commands or tools to ensure its proper functioning.
Update NativeScript CLI: Ensure that you have the latest version of the NativeScript CLI installed. Run the following command to update it:
npm install -g nativescript
Check NativeScript configuration: Verify the configuration of your NativeScript project. Run the following command in the project directory to ensure the necessary platform and emulator configurations are set up correctly:
tns platform list
Reinstall platform: Try reinstalling the Android platform for your NativeScript project. Run the following command in the project directory:
csharptns platform remove android
tns platform add android
Reset ADB: Reset the ADB server by running the following commands:
perladb kill-server
adb start-server
If none of the above steps resolve the issue, you can seek further assistance from the NativeScript community forums or GitHub repository. Providing additional details about your environment, such as the operating system, NativeScript version, and emulator details, may help in troubleshooting the problem more effectively.
