There is a big database(15M) in my application,
it is too big to download the apk if I publish the source database in
myapp.apk.
So I encode the db to binary files(300k).

But the new problem is I should decode binary files and create the
database(with data), this procedure take about several minutes, so I
can NOT do this in SQLiteOpenHelper.onCreate(), this is too slow for
user experience(though it is a one time procedure, it is still
unacceptable).

My application has NO main activity entry in launcher, the main entry
is BroadcastReceiver.onReceive, the infomation should display to user
immediately when receiving the broadcast, so I have no chance to
display a several minutes "Initializing, please waiting..." UI.

The best chance to create database and init data immediately after
install, but how to do this, is there any broadcast? or is there any
AndroidManifest attribute?

pls help!
