 Hi All,

      I developed a map application with overlays. I am able to show
current location also. I want to display dynamic routes from current
location  to different points(overlays). I have stored several
points(geo coordiantes) using array. Should I use the graph data
structure concepts using some algorithms?

Thanks in advance

1. Embed a database in the apk

Hi all,

I am writing an app in which I must embed a (read-only) database. It is
quite simple (category->subcategory->description), but big (3-4 MB).

I saw other softwares putting the SQL in the assets folder, and then
populate a SQLite DB, but this way I would fill double the space (6-8
MB) on the device.

Is there a way to directly use a sqlite DB in the assets folder? Or
should I use some other data structure?

As I said, the data is read-only and the software is still in the
"project" stage, so I can adapt the data model to anything.

Thank you very much.

2. can cursor block

Hi all,
I have the following issue. I get a cursor in some background thread
and pass it to the gui thread. In the gui thread i use the cursor to
create cursorAdapter and fill some ListView. So far if the database
access blocked there will be no problem because it's made in other
thread. So the cursor is fetching the data rows when they are needed
which will be when i scroll the listview and in this case if the
database blocked will i get activity not responding.
