Trying to install my own app from play store, it says "You cannot install this app because another user has already installed an incompatible version on this device"
Note - I've uninstalled the debug version, and also cleared my Cache. Still can't get it to install from Play Store.
My phone is not rooted, so as another similar answer here on stackoverflow suggests, I cannot use a root file explorer to clear data.
Refer this , Actually your debug version of the app didnt get uninstalled properly
