In spite of app version is greater, Android Build failed with "INSTALL_FAILED_VERSION_DOWNGRADE"
Hi,
I tried update my released Android app, but It was failed because of "INSTALL_FAILED_VERSION_DOWNGRADE"( but I change version in projectSetting.asset).
My flow is below 1. install my app from GooglePlay (version = 1.0.0) 2. In Unity, change version to 1.1.0 in ProjectSetting.asset 3. Build And Run
When I uninstall old version app, Install was succeed. But I'd like to access old version local file from new version app. ( local file access by windows explore is forbidden in my workplace)
Is there any way to solve this issue without uninstall ?
Environment Unity 5.6.5 Windows 8.1
Thanks .
The version string is completele irrelevant. The only important number is the version code. It's an integer value which usually starts at 1. Each new published version needs to have a greater number than all versions before. How you increment it is up to you but it's recommended to increment it by just 1 each time.
See the PlayerSettings for more details. Specifically the 5th image from the top:
Bundle Version Code
An internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName attribute. The value must be set as an integer, such as “100”. You can define it however you want, as long as each successive version has a higher number.
Thank you very much!
