INSTALL_FAILED_UPDATE_INCOMPATIBLE: Подпис на пакети не отговарят на предварително инсталираната версия; пренебрегване!
You need to uninstall previous version from it because you are using a different
signature than the original. If it is not working it might be because it is
still installed for another user on the device. To completely uninstall,
go inside emulator
Settings -> Apps -> Hagnostic News -> Options (the three dots on top right)
-> Uninstall for all users
