So, I found the 2.1 version of the Gmail apk and I installed that via adb. Gmail then shows up but when you try to launch it, nothing happens. From my perspective, Gmail is a secondary concern.
I want to get Google Reader and Google Books running. I have installed these apps and they both startup with a prompt for account information. In Reader, at the top of the screen it says 'Google Reader Accounts', in the middle of the screen, it says 'No accounts', and at the bottom there is a button that says 'add account'. When I click that button, a pop-up dialog comes up that says 'sign-in failed'. The books screen is similar but there is no button and no way to move forward.
I believe these apps are dependent on other apks that handle google accounts and sync data. Any insight would be appreciated.
