L-Clock

L-Clock is an Android app that fetches data from NASA.gov and SpaceflightNow.com and creates a formatted list of upcoming rocket launches. Touch an item in the list to display the launch date/time and a countdown.

L-Clock is currently in beta. There are a few obvious issues that will be fixed by v1.0.0, but the basic concept is mostly functional.

L-Clock is free and open source software (FOSS)!
It is currently ad-supported, but feel free to remove the ads from the code and compile yourself.
Code contributions through GitHub are encouraged for the benefit of the user community.

v0.6.5 [2012-01-01]

• Fix NASA parsing, again.
• Fix Spaceflight Now parsing of dates containing "NET".
• Remove touchscreen requirement. (Makes compatible with Google TV)
• Update AdMob and AdWhirl SDKs. (Was using very old versions due to a significant visual bug with house ads in newer versions of AdWhirl including this version, decided the potential benefit of new features outweighs the bug)

v0.6.3 [2011-10-13]

• Add indeterminate progress indicator to title bar when list is refreshing.
• Fix occasional crash when opening list, mostly on some slower devices. Caused by the list adapter being read and written in two different threads at the same time and the read happens on an empty list before the write; fixed by combining into single thread with read after write.
