Hi,
So, i solved the 80% of the problem, now when debugging i have all the path
to the settings.dat:
/data/data/acrburant.android.com/files/settings.dat
However, i'm facing a problem when writing the file to the SDCARD. I have
permission denied and SDCARD not mounted exception.
Here is the code:

Do you have a memory card in the phone?
If you do, make sure it's not mounted as a disk drive by your
I added this in the emulator:
-sdcard /Users/Alaeddine/Documents/workspace/android_sdcard
I verified also that the /sdcard is well mounted by the emulator, not by the

This can not be a code problem ?
By the way, i solved the problem of settings.dat path by doing this(to all

So i just have this problem to solve now. I'm trying everything, followed
this link(http://www.brighthub.com/mobile/google-android/articles/33240.aspx)
as well, and always have the problem of sdcard not mounted!I verified with
Settings-Storage and it indicated unavailable . Any idea ?
Thank you.
So i maked this:
catch(FileNotFoundException ex){
Toast.makeText(context, File Not found, Toast.LENGTH_SHORT).show();
String x=ex.getMessage();
Log.d(Carburant, x);
}
Here is the message i get:

A few things.
1 - For the target file, don't use SDCARD in your paths.
Environment.getExternalStorageDirectory already gives you the path to the
top-level directory (root) of the memory card.
Android 2.2 uses a path that's different from earlier versions, and you can
rely on this function to do
I really don't know what method to use! all right, i have this:
copyfile(context,data/data/
carburant.android.com/files/alaa.peugeot.settings.dat,sdCard.getAbsolutePath()
+ /Carburant/storeddata.dat);
I have to replace data/data/
carburant.android.com/files/alaa.peugeot.settings.dat by a method.
Review this:

You don't need an Android example. This is all standard Java IO. AGAIN:

So all this lines are false, they are not correct, all the problem come from

Your question doesn't make any sense, is it that the file can't be
opened that you need help with? You can stop the debugger when you get
the error and read the message that it reports. Typically it might be
something like the file doesn't exist or that you don't have
permission to open it. Did

You can't read or write a file without opening it.
And you can't copy a file without opening source for reading and destination
for writing.

Debug your transfer() method and make sure, that all the path are
correct (e.g. no duplicated slashes) If i'm not mistaken
Environment.getExternalStorageDirectory().getAbsolutePath() returns
the slash terminated string.
Make sure that the dir is created and your context was got correctly.

Alaeddine, forums like this exist in order for people to help one
another. It's very likely you'll not get someone to review your code,
point to a line or two and tell you precisely how to fix it.
As a programmer/developer, you have to be resourceful. And this will
mean you'll have to read

I think you are not creating a directory for the target file. Look up
File.mkdir and mkdirs.

OK. From what?
why the file is not copied ?
I assume your FileNotFoundException has something to do with it.
I copied the apk to my phone, and when i tap in the menu button
export, same problem! Plus the directory is not created(in the
Simulator yes the direc is created)!
Here is the menu button export code:
case R.id.exporter:
final SharedPreferences preferences = PreferenceManager

Step through your code and figure out which one is throwing the exception,
for starters.
Sorry, but do you mean that i put a break point in this
line: catch(FileNotFoundException ex){
Toast.makeText(context, File Not found, Toast.LENGTH_SHORT).show();
and see what it gives as output values ?

Nope, he means step through until you *get* the exception...
However, if you put a breakpoint at *that* line you should be able to read
(in the Eclipse debugger) what file is causing you trouble.
