I am a new user to Android Studio. I took a class over the summer and all my projects worked (and still work). I have followed all the advice from all the advice columns but I am still getting "Session 'app': Error Installing APK" when I try running my latest projects on my Samsung S4 mini. Again, all the other projects from this summer still work. I have tried
- restarting everything (android studio, computer, phone, etc)
- I have reloaded Android Studio
- I have created multiple signatures and followed the directions on https://developer.android.com/studio/publish/app-signing.html
Does anyone have any other suggestions??
