Is there any way to install in the same android mobile a debug version of my app AND a google play store version of my app? I try to setup on my android multiple users, but when from another user than the owner user (where the debug version of my app is installed) I try to install the app from google play store I receive:
you cannot install this app because another user has already installed an incompatible version
No. Not unless you change the package name of your debug version application. See detailed discussion here
