Performance improvement suggestion #48

Dear developers,

I am analyzing Geohash Droid using a static code checker. I found some 
potential slow operations in Geohash Droid's UI thread.

Android documentation says this:

http://developer.android.com/training/articles/perf-anr.html

"Any method that runs in the UI thread should do as little work as possible on 
that thread. In particular, activities should do as little as possible in key 
life-cycle methods such as onCreate() and onResume(). Potentially long running 
operations such as network or database operations, or computationally expensive 
calculations such as resizing bitmaps should be done in a worker thread (e.g., 
via AsyncTask)."

I found the following event handler performing database queries and file IO:

net.exclaimindustries.geohashdroid.MainMap.onResume()

Do you think these slow operations will affect Geohash Droid's performance? If 
yes, perhaps moving them to a separate thread can help make Geohash Droid super 
smooth in user interaction. Looking forward to your reply and hope I can help 
improve Geohash Droid.
