Prefer is android advanced sharedpreference library.
Supporting Integer, String, Float, Long, Boolean.
init prefer class with context
public static void init(@NonNull Context context);
public static void init(@NonNull Context context, @NonNull String fileName);you can get sharedpreference object
public static synchronized SharedPreferences getSharedPreferences();set/get key-value pair
public static void set(@NonNull String key, @NonNull Object value);
public static <T> T get(@NonNull String key, @NonNull T defaultValue);init prefer AppApplication.java
class AppApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
Prefer.init(this);
}
}add application in AndroidManifest.xml

Before you know Prefer
void setDataUsingSharedPreference(){
SharedPreferences sharedPreferences;
SharedPreferences.Editor editor;
sharedPreferences = getBaseContext().getSharedPreferences("data", MODE_PRIVATE);
editor = sharedPreferences.edit();
editor.putInt("int1", 1);
editor.putInt("int2", 2);
editor.putString("string1", "hello1");
editor.putBoolean("boolean", true);
editor.putFloat("float1", 1.3f);
editor.commit();
// very complex...
}After you know Prefer
void setDataUsingPrefer(){
Prefer.set("int1", 1);
Prefer.set("int2", 2);
Prefer.set("string1", "hello1");
Prefer.set("boolean", true);
Prefer.set("float1", 1.3f);
// awesome! very simple!
}Using default value, the type is automatically checked and loaded.
Before you know Prefer
void getDataUsingSharedPreference(){

String string1 = sharedPreferences.getString("string1", "none");
Boolean boolean1 = sharedPreferences.getBoolean("boolean", true);
Float float1 = sharedPreferences.getFloat("float1", 0f);
// too many functions.... very very complex
}After you know Prefer
void getDataUsingPrefer(){
int int1 = Prefer.get("int1", 0);
int int2 = Prefer.get("int2", 0);
String string1 = Prefer.get("string1", "none");
Boolean boolean1 = Prefer.get("boolean1", true);
Float float1 = Prefer.get("float1", 0f);
// Automatically cast everything to as single function!!
// Amaaaaaazing!
