I have recently bought a new PC and setup Android Studio 1.5.1 on it. I copied source project folder from AndroidProjects folder on old PC to a new one on new PC.
I was able to open the project and succesfully compile and run in emulator. However when I connected my Galaxy S6 and tried to debug in it, it first complained about old version of app being installed (from old PC), and asked if I wish to uninstall. I said yes and since then I always get the folowing error:
Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]
I am not asking how to resolve this issue (altho help would be appreciated), rather I am asking what is different on my new PC that makes compiled app incompatible in some way with old one? Nothing in source is changed, I do not sign my APK with any key now.
I need to know in order to avoid issues in future, when app is released and I need to change PC again.
Thanks!
