Test ionic app on an actual device or emulator using visual studio code and android studio

Question

I am a newbie with ionic app development and I build an ionic application and it works well on the browser everytime I run a test. Now, I am trying to run my ionic application to an actual device or an emulator using the command 'ionic cordova run android' but I always get this error

Ionic CLI version: PRO 4.2.1 Cordova version: 8.0.0 NPM version: 6.4.1 Node.js version: 8.11.3 Visual Studio Code version: 1.30.2 Android Studio version: 3.3 Java version: 1.8.0_191

I have also tried the following tutorials but I always get the same problem. https://geeklearning.io/live-debug-your-cordova-ionic-application-with-visual-studio-code/ https://moduscreate.com/blog/ionic-cordova-debug-device-visual-studio-code/ https://www.youtube.com/watch?v=ZWrKakQOCYE

I hope someone can help me with this. Thank you in advance.

Maybe plugin dependency problem. Remove this cordova-plugin-firebase plugin, then use this command on CLI:

ionic cordova plugin rm cordova-plugin-firebase cordova clean ionic cordova prepare android ionic cordova run android I hope solve your problem.
