Ah!!! So you have a *compile* error!
Ok, try this:
String fil = "test2";
String string = "exempeltext";
FileOutputStream fos;
try {
fos = openFileOutput(fil, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
} catch (IOException x) {
Log.i(TAG, "Cannot open file: " + x.toString());
}
Eclipse (or any other Java compiler) checks exception signatures at
compile time.
The compiler knows that openFileOutput *can* throw a
FileNotFoundException, since it's declared like this:
public FileOutputStream openFileOutput(String name, int mode)
*throws FileNotFoundException*
It also knows that write() and close() *can* throw IOException.
Since onCreate says it does not throw any exceptions, the compiler flags
this as an error, and suggests that you either:
1) catch any exceptions from the above methods, and don't let them
propagate out of onCreate or
2) change the signature of onCreate to indicate that it, too, can throw
exceptions (which is not really an option, because onCreate is an
override of a method of Activity, and you can't add new exceptions when
overriding methods).
Since exception handling is one of the fundamentals of Java, you should
take some time to learn more about them. There are lots of articles and
samples on the net, here is one (from 1998, and things haven't changed
since then):

Thanks for the answer and for testing the code. I'm developing on
Eclipse - this is my first try on android developing and my java isn't
that good in the first place. I'm using a virtual andriod phone for
testing, but i can't even compile the code because of the error
message. I will try and reinstall Eclipe or another API and see if it
helps.

Michael,
Your code (as posted) is correct. Just in verify, I just pasted in
verbatim into my application and verified that it works (as it should).
Try removing and reinstalling the application, see if that helps.
Other than that - is this a Samsung Galaxy S with 2.2.1 firmware, by any
chance?

You do not need external storage permission to save local data.
Any other permissions than can be the issue? I've tried reading some
documentation for the answer, but i can't find anything about internal
storage and permission.
