Peter, This is because the Version Code(standalone setting==>Android) is numerically lower than the currently installed version. Either up the Version Code or uninstall/reinstall the app.
Other issue you can run into: (Inconsistent Signing error) 1) When doing "test" installs if you move to another PC/Mac/VM the "Test Signing"(standalone setting==>Android) key pair is specific to the box. To solve this you need to either go back to the original OS or uninstall/reinstall the app. 2) If you install a Signed version over a Test Signed version or vice versa you will get the same error. The solution is the same. Either use the same signing or uninstall/reinstall the app. Ralph DiMola IT Director Evergreen Information Services [email protected] -----Original Message----- From: use-livecode [mailto:[email protected]] On Behalf Of Peter Reid via use-livecode Sent: Wednesday, October 09, 2019 7:26 AM To: [email protected] Cc: Peter Reid Subject: Building Android Apps I've been building Android apps using my iMac for some time. However, yesterday I started to get an error message "Failure [INSTALL_FAILED_VERSION_DOWNGRADE]" when I try to build an Android standalone app. Any ideas what's causing this and how to fix it? Separately I'd like to be able to build Android apps on my 15in MacBook Pro so I can do on-the-fly fixes when out and about. However I can't find up-to-date instructions for installing Android support. Some searches produce various suggestions including LiveCode tutorials about setting up a Mac to work with LiveCode and Android but they all seem to be out of date and contradict each other. In addition there's no advice for how to get to a clean state of Java and Android. Can anyone point to up-to-date details for setting up a Mac to create Android apps with minimal installation of supporting technologies, both as a clean set-up and how to clean up JDK and SDK support if necessary?
