Hello, I'm writing a blackberry application that reads ints and strings out of a database. This is my first time dealing with reading/writing on the blackberry, so forgive me if this is a dumb question.
The database file I'm reading is only about 4kB
I open the file with the following code
fconn = (FileConnection) Connector.open("file_path_here", Connector.READ);
if(fconn.exists()==false){fconn.close();return;}
is = fconn.openDataInputStream();
while(!eof){
//etc...
}
is.close();
fconn.close();
The problem is, this code appears to be eating a LOT of memory. Using breakpoints and the "Memory Statistics" view, I determined the following:
calling "Connector.open" creates 71 objects and changes "RAM Bytes in use" by 5376
calling "fconn.openDataInputStream();" increases RAM usage by a whopping 75920
Is this normal? Or am I doing something wrong? And how can I fix this? 75MB of RAM is a LOT of memory to waste on a handheld device, especially when the file I'm reading is only 4kB and I haven't even begun reading any data! How is this even possible?
