I'm trying to drill down why this is so, but much more importantly I'd like to fix this problem.
The situation: I've been a longtime user of the Katana ROM as it has been both stable, fast, and good for battery longevity in my experience, even with the OC/1.67 kernel installed. I really like this ROM and have tried the others that GT made, but all of them have the same problem.
The problem: I first noticed this with the Google/Android Keyboard, later I noticed it with the Gmail app. These apps are not updatable in these ROMs. The Android Keyboard for quite some time was the same version that was available at the Play store, but it is now at least one version newer. When attempting to update this app, the Play store politely tells you that the file was not signed properly, to uninstall the old version and then reinstall the new one. The same issue pops up with the Gmail app; in Katana, the Gmail app is the one made before the summer update, and it has no tabs for categories. This is a feature I find immensely useful in order to actually manage email on my phone so I'd love to use it, but the same problem occurs. Side-note: Samurai has the updated, tabbed Gmail app, but Samurai appears to drain my battery rather quickly. I haven't attempted to update its Gmail app, but its Android Keyboard does not update with the same error as the Katana rom gives.
I have tried various suggestions in other threads to fix this problem: uninstall the offending app, delete cache, then attempt to reinstall. I have removed the apps through the app manager as well as Titanium Backup. I have tried to reinstall with both the Play Store downloaded versions and with apks that I have grabbed from other sources. In each case (Gmail and Android Keyboard) the install fails. Is there anything else I can try to drill this down? If I could just get the Gmail app updated through Katana, I'd be thrilled at this point.
