Turns out that there is no API method for solving my problem, below is
a 4-line solution.
public static String getSharedPreferenceName(Context ctx, int
prefResId){
String packageName =
ctx.getApplicationContext().getPackageName();
Resources res = ctx.getResources();
String entryName = res.getResourceEntryName(prefResId);
return packageName+"_"+entryName;
}
