I created an Ionic 4 appliation, from other as base (cloning folder and modifing). When I Install one from APK (debug version), the other app dissapears. ¿Why this occurs? Apps sharing some id? What I must to change for solve?
While you wait for better answers, I’m going to try to convince you not to do this.
Even if you do figure out all of the places that need changing, what happens in the future when Ionic or Angular or Capacitor or any of the underlying build scripts change the way that they manage configuration? You’ll have to redo all the detective work again.
I think a much more sustainable approach is to always spawn new projects. You can always copy as much source code as you like from other projects, but I would never actually clone a project folder.
