I've noticed a couple of things that need attention by the Android developers:
1. The Android app is not detecting the external sdcard, it 'sees' the internal memory as the external sdcard no matter which option I select. I am using the Samsung Galaxy S3 on Android 4.1.2, Using a file manager I see two separate 'sdcards' one is called sdcard0 which is simply a partition on the internal drive, the other is extsdcard which is my external sdcard. This needs addressed.
2. The Android app tends to freeze then crash when accessing offline lists, this happens when the list is rather large (over 50 caches) and happens nearly every time.
I am a bit disappointed that this official app is less feature rich as other apps that use the official Groundspeak API.. I hope to see some more functionality added in the near future (akin to the iPhone app perhaps).
