Returns an array of strings naming the private files associated with this Context's application package.
In order to support calls to getCacheDir(), we create a temp cache dir (inside the real one) and return it instead. This code is basically getCacheDir(), except it uses the real cache dir as the parent directory and creates a test cache dir inside that.
Returns the absolute path on the filesystem where a database created with
openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory)
is stored.
name | The name of the database for which you would like to get its path. |
