Alternatives to deal with many SharedPreferences

Issue

I'm developing an Android app which uses a high amout of SharedPreferences. I have several SharedPreferences files and I'm making up to 77 calls to these files throughout my app. Sometimes I'm using :

static final String FileName= "SharedPreferencesFile";

at the beginning of my activities and then :

SharedPreferences settings = getSharedPreferences(FileName, Context.MODE_PRIVATE);

whenever I need to use them. Some other times I'm just refering to the files directly as in:

 SharedPreferences settings = getSharedPreferences("SharedPreferencesFile", Context.MODE_PRIVATE);

I'm trying to organize things now so I would like to know about different alternatives to do it. My questions are:

1. Should I define a single "SharedPreferencesFile" for all the variables in my app or using multiple files as I'm doing now is ok?
2. Should I define all these String FileName= "SharedPreferencesFile" in the strings.xml from my app resources folder instead of putting them at the beginning of my activities and the just use them as SharedPreferences settings = getSharedPreferences(R.string.SharedPreferencesFile, Context.MODE_PRIVATE);
3. Should I create a helper class that handles all shared preferences calls for every activity as suggested in Android Shared Preferences

Solution

Should I define a single "SharedPreferencesFile" for all the variables in my app or using multiple files as I'm doing now is ok?

If you can categorize them in a logical fashion do it. Dont just do it for the sake of having them split over multiple files in a random fashion. It will lead to a lot of confusion later

Should I define all these String FileName= "SharedPreferencesFile" in the strings.xml from my app resources folder instead of putting them at the beginning of my activities and the just use them as SharedPreferences settings = getSharedPreferences(R.string.SharedPreferencesFile, Context.MODE_PRIVATE);

It is always good to have string resources extracted to strings.xml. Be careful if you are adding translations and make sure you don't translate the names. Mark them as notranslate string resources.

Should I create a helper class that handles all shared preferences calls for every activity as suggested in Android Shared Preferences

There are already several available. Here is one that I created to simplify the use of SharedPreferences. It is open source and can be used simply by adding a gradle dependency - Android-SharedPreferences-Helper
