I have been using SharedPreferences in my app to save details about text files as it is very easy to access and alter. The problem I've encountered is that when I delete the text file, it's difficult to delete the associated SharedPreferences file as it's stored in different places on different devices and there is no generic getSharedPreferenceDir() as @CommonsWare mentions here.

My question is this: Is there another method I should be using to store a HashMap that is as easy to use as SharedPreferences in terms of creating and retrieving information but is also easy to delete?

I am aware of the sharedPrefs.clear() method, but I am referring to deleting the actual XML file and not simply clearing its contents. Thanks in advance.

I've seen that and it seems like a good solution (it works on both of my devices), but I've read that some manufacturers store the shared preferences elsewhere. Is this true or is it safe to assume that they'll be there? – willlma Feb 25 '13 at 11:53
i think it is depend on android os not a manufactures – Kirit Vaghela Feb 25 '13 at 12:22
