I don't think so, all the processes run in a sandboxed environment so
an application shouldn't be able to alter other applications. The
orekit application hasn't even the permission to write on the sdcard.

Can you go into your Android device into "Settings => Applications =>
Development => USB debug", plug your Android device on a computer and
try to run "adb logcat" ? (it's located into the platform-tools folder
of the SDK). It will show you the device syslog and you'll have the
backtraces of the crashing application which may give you enough
information to figure out what's wrong.

By the way, in the last commit I now cleanly handle OrekitExceptions
and since yesterday all the computation have been moved in a worker
thread with a ProgressDialog so the next snapshot should be far more
stable.
