Where are default shared preferences written to?

I wish this helpful for you I am trying to initialise default shared preferences upon first run of my app. I found out that depending on how I do it, there are differences in the shared preferences file on the Android file system. , I'll address your second case first:
code :
myKey = pref.getString("key", "default value");
SharedPreferences.Editor editor = pref.edit();
if ((myKey = pref.getString("key", null)) == null) {
    myKey = "default value";
    editor.putString("key", myKey );

Default value not reflecting-shared preferences

fixed the issue. Will look into that further As per comments on the OP:
PreferencesActivity saves each item in the preferences for use later in the app. These values are also retained after exit. A "default" value only shows up if the preference has not been set before, which means your value will only be false until someone sets it to true. They can later change it back to false, but it will never again use the default value.

Does that help In your class SharedPref, you defined constants DEVICE_ID and KEY_HASH as both equal to "". So I guess they refer to the same field in your Shared Preferences. Although it seems weird than an empty field can exists.

Any of those help You don't have to set them to be the same. Why the Android team at Google did not create an overloaded method that does not take a default value like getString(String key) is beyond me. If the values are different, you will get the value you set on android:defaultValue on your XML.

like below fixes the issue sharedPrefs.getInt("YEAR" , 2014);
would make sure that if nothing is saved in the SharedPrefs for the key "YEAR", then it will return the value 2014 by default.
