[android help] creating files with IF logic inbeded

Actually two questions:

The main question: I hope it isn't true that you can't have simple logic in writing out a file!!! I have a cursor to load a dynamic list on the screen normally invoked by onCreate. That works. Now, I need to write out to the "sdCard" as a back-up. (If my watch decides to reset to day one, I will reload - it also allows me to add entries from my PC which has a keyboard.)

I decided the best way is to call the existing cursor but set a switch to indicate to write it out. Files require a try - catch, so I put it around the open, the write, and the close. The "writers" are undefined. So I put it all inside one "TRY" that worked if there are no brackets - no "IF"s.

But add "IF (--SWITCH SET)" {---writer.write(strBuRec); ..}" which requires {--} now again the writer is undefined.

I sure hope I am doing something else wrong (probably something stupid)! I can copy the code into a second cursor, but prefer not to.

Second question: Note the close cursor (//cursor.close();) is commented out. This is because if I repaint the screen or in this case, re-invoke the cursor to write out my file, I get cursor closed. I can only load the cursor once if I close it.

Note: This is a simple app for my WIMMOne so it needs version 7. This code is in a fragment, (bad decision, but it's there).

Many thanks, Clark
