Just a heads up, I have previously installed my app to the Android 2.2 and 2.1 simulators and when I tried installing it on the Android 2.3 simulator it failed.
I have a feeling there is a problem…
Google once again changed all of the tooling. We are working on a solution.
I was using a packaged apk file to install.
So far all of my Titanium Mobile apps I have installed over adb to Gingerbread seem to functioning correctly.
