问题
I'm trying out the in-app update feature and I'm getting a FAILED install status and a -100 install error code. Is there any way for me to know what may be causing this?
I implemented the flexible in-app update and I'm logging each step. Followed Android devs tutorial here
I'm generating an apk with a lower version code as the one in Google Play and signing using the same signing key.

Clear the PlayStore app Storage from the Android Settings App - Settings -> Apps -> Play Store -> Storage -> clear data
and this error will disappear .. I don't what is the actual reason for this error .. and there no documentation that can guide you.

I've been dealing with this issue for a day or so now and the issue was that my apk wasn't signed and verified. I believe that when you run an unverified apk AppUpdateManager will check for an available update on the PlayStore, however during the installation process it will fail when it realizes that its replacing an unverified apk with a verified one.
