Android App Not Install. An existing package by the same name with a conflicting signature is already installed
In my emulator, when I try to do an upgrade of my apk programmatically. I get:
Android App Not Install.
An existing package by the same name with a conflicting signature is already installed
I'm still in the testing phase of this upgrade, so the file I download is a signed apk of a previous version, which I think should work without any issues.
From the suggestion in: an existing package by the same name with a confilcting signature is already installed I tried to run the emulator both in debug mode and in normal mode... neither worked.
Any thoughts on what I'm missing?
Answer
I had the same error message, but these answers did not help. On a 4.3 nexus 7, I was using a user who was NOT the owner. I had uninstalled the older version but I kept getting the same message.
Solution: I had to login as the owner and go to Settings -> Apps, then swipe to the All tab. Scroll down to the very end of the list where the old versions are listed with a mark 'not installed'. Select it and press the 'settings' button in the top right corner and finally 'uninstall for all users'
