Failed to Install (File I/O Error) Android Plus

Failed to Install (File I/O Error) Android Plus

I have an application that was initially installed on every device but has been uninstalled (separate issue) in the past. The Installed Applications panel will list it as (example) TestApplication Version 1.0. I have a new version of the application that needs to be deployed to every phone and the phones with the application already unistalled fail "Failed to Install (File I/O Error)".  The devices with version 1.0 transition to version 2.0 with no issue. How do I get around from installing the application to the failed devices one by one?

MobiControl V13.3.0.3965

 

Thanks in advance.

If you are installing the APK on the devices via Package then you will need a Pre-Install script within your Package that Uninstalls the App before the new version of the APK is installed. This will have the negative effect of wiping out any permissions and restoring the prompts that may have been manually granted in the past as well as wiping out any App Cache or App Data that may exist on the device but will have the positive effect of allowing you to cleanly install the new APK version. In the future you should be able to do a direct upgrade to say version 3.0 provided that you use the same SOTI Package but just update the APK contained within and increment the Package version number accordingly.

Matt,

Thank you for the information, yes, the APK is deployed via package but I did not add a pre-installation script. I'm OK with losing permissions and cached data. This should resolve my issue going forward, but my current issue is still open. About 75% of my phones have an uninstalled version 1.0 and a failed installation of version 2.0. Any suggestions on how to resolve this?
