title: Can I overwrite a Unity app with a native android app
body: <p>I have a application build with Unity and now i'm thinking it would be better as a Native Android app.</p>
  
  <p>The reason I wrote the app using the Unity framework was to be able to easily deploy to IOS as well. My numbers on IOS are really weak so I basically want to focus on Android.</p>
  
  <p>I want to make it a Native app without making a new app like "My app 2" because of the existing user base. </p>
  
  <p>My assumption is that if I have the keystore I can simply upload a new APK to overwrite the old one. Am i wrong? Is this even a possibility ? Are there any concerns with this approach? Is there anyone here who have done this successfully?</p>
