I am pretty new to Ionic. I tested with the demo project Blank
ionic start --v2 myApp blank
it works well. Next, I edited the contents of index.html, adding some DOM. However, when ionic serve again, the content of index.html is restored to the original contents.
I also added Android platform. It is same: if editing any files of Android, cordova build will restore the files.
Could you shed a light what I missed? Thank you!
