I have faced the same issue and Solved... What you need to do is

  • first Solution

    • ionic platform rm android ,

    • ionic platform add android ,

If that does not work then

  • Second

    • Remove your all plugins and add again ,

Solved my problem

Just remove the node_modules folder from your project using:

rm -rf node_modules

and then install all dependencies again:

npm i
