Getting "caching failed" exception when invoking methods on Android

[GoogleCodeExporter]

I'm getting the "caching failed" exception by just adding a line which invokes 
a method, like:
User.getTopArtists(user, key);
I've tried two different keys and various usernames, with no luck.
On an blank Java project, the API works perfectly.

I'm using the Android SDK on Eclipse, and the code is running on Android 2.2.

Oddly enough, some of the methods actually work, such as getLovedTracks() and 
getRecentTracks().

Is there any incompatibility with Android, or any specific changes I should 
make for the API to work with Android?

Do you have permissions to write to the file system/the specific directory the 
cache is being written into on Android?
If not you will have to use a different cache implementation or none at all 
(null).

Some methods will work anyway because they won't get cached by default.

Thanks for the quick answer!

The problem isn't on the permissions, but Android seems to be very picky about 
File I/O.

The rest of the API seems to work when I call setCache(null), and that was what 
I really needed.

Thanks, and sorry for taking up your time!

Just add this line somewhere in your code that will get run prior to calling 
any of the api methods:
Caller.getInstance().setCache(null);

If you still want cache support, try something like this in your main 
Activity's onCreate() method:
Caller.getInstance().setCache(new FileSystemCache(getCacheDir()));

Hi,
I call Caller.getInstance().setCache(null);
before call the API methods, but I still get "caching failed" exception.
Any idea ?

Just set the Cache to FilesystemCache with the adnroid files DIR of your app. 
Worked for me..

Caller.getInstance().setCache(new FileSystemCache(getFilesDir()));
