Answer 1

Rather than rolling your own utility methods, you may want to consider using the apache commons FileUtils library. It contains a lot of useful File manipulation methods and makes operations like this very trivial.

Here are the JavaDocs

And here is an example:

try {
    FileUtils.deleteDirectory(context.getCacheDir());
} catch (IOException e) {
    Log.e(LOGTAG,"Error deleting cache dir", e);
}

Alternately, rather than deleting the whole cache directory, you may want to create subdirectories within the app's cache directory for specific data. Than you can delete those specific directories when required (e.g. on user logout).
