Auto-save duplicates log entries about alogcat

[GoogleCodeExporter]

I've faced this problem too.
As Android only savs 64kb logs of the system.
if the interval is so short,there should be duplicates logs,
while some logs missed if the interval is too long.
I first used a command "logcat -c" to clear the buffer after every
command of fetching logs which had a short interval,
but it didn't work.In my opinion,it's because of the permission,
because it works on adb.
and then a got another solution:save the last log's time tag of the
latest saved logs,and filter current logs by the time.

for power consumption reasons, the og save feature isn't sitting in the 
background reading the log and keeping a bufffer. it works by waking up every 
so often and recording a snapshot of the log.

to avoid duplicates, it would need to look at existing log entries, by 
re-reading the file, and find the last written log entry. to do this, it would 
need to parse every log entry line to extract the time. 

the other option would be to keep a process running, always, in the background 
that is recording every log entry and copying it into the file.

neither of these options is nice on the battery. perhaps there's a better way, 
but it's not obvious to me at this time.
