SharePreferences is very popular with any project and all most all project has SharePreferences for saving data. This library will help you faster in configuration and use SharePreferences in your project. Let's setup and enjoy!

Setup

1. Add to build.gradle in app level

   implementation 'com.github.tntkhang:preferences-helper:1.3.2'
   

1. Init the PreferencesHelper in your CustomApplication.java extend from Application with 2 ways:

   • Will use app name as of Preferences file name PrefHelper.initHelper(this);

   • Will use CustomName as the name of SharePreferences file PrefHelper.initHelper(this, "CustomName");

2. How to use

   SET VALUE:

        PrefHelper.setVal(KEY_BOOLEAN, true);
        PrefHelper.setVal(KEY_DOUBLE, 123.123);
        PrefHelper.setVal(KEY_FLOAT, 234.234f);
        PrefHelper.setVal(KEY_INT, 345);
        PrefHelper.setVal(KEY_LONG, Long.MAX_VALUE);
        PrefHelper.setVal(KEY_STRING, "Khang");
   
        UserModel userModel = new UserModel("KhangTran", 27);
        PrefHelper.setVal(KEY_OBJECT, userModel);
   
        List<String> stringList =  Arrays.asList("Tran", "Nguyen", "Thai", "Khang");
        PrefHelper.setVal(KEY_ARRAY_LIST, stringList);
   
        String[] arr = new String[4];
        arr[0] = "Tran 2";
        arr[1] = "Nguyen 2";
        arr[2] = "Thai 2";
        arr[3] = "Khang 2";
        PrefHelper.setVal(KEY_ARRAY, arr);
   
        Map<String, String> stringMap = new HashMap<>();
        stringMap.put("Tr", "Tran");
        stringMap.put("N", "Nguyen");
        stringMap.put("Th", "Thai");
        stringMap.put("K", "Khang");
        PrefHelper.setVal(KEY_MAP, stringMap);
   

   GET VALUE:

   boolean booleanValue = PrefHelper.getBooleanVal(KEY_BOOLEAN, false);
   double doubleValue = PrefHelper.getDoubleVal(KEY_DOUBLE, Double.MIN_VALUE);
   float floatValue = PrefHelper.getFloatVal(KEY_FLOAT, Float.MIN_VALUE);
   int intValue = PrefHelper.getIntVal(KEY_INT, Integer.MIN_VALUE);
   long longValue = PrefHelper.getLongVal(KEY_LONG, Long.MIN_VALUE);
   String stringValue = PrefHelper.getStringVal(KEY_STRING, "Empty");
   UserModel userModel = PrefHelper.getObjectVal(KEY_OBJECT, UserModel.class);
   List<String> stringList = PrefHelper.getListVal(KEY_ARRAY_LIST);
   String[] strings = PrefHelper.getArrayVal(KEY_ARRAY);
   Map<String, String> stringMap = PrefHelper.getMapVal(KEY_MAP);
   
   Map<String, ?> stringMap = PrefHelper.getAll();
