Background

I have various apps on Google Play and sometimes it is required to access shared preferences from anywhere within an app. So, I wrote this library to provide that functionality easily and quickly. Please read below to know more about its usage.

Usage

It is based on the singleton approach to manage shared preferences within an app. This library is fully commented so I am highlighting some of the features below.

Please follow and keep exploring the GitHub repository to find out more hidden features.

Initialize

DynamicPreferences must be initialized once before accessing its methods.

// Initialize with application context.
DynamicPreferences.initializeInstance(applicationContext);

After initializing, its various public methods can be accessed via getting the initialized instance.

Save

It supports the saving of boolean, int, String and Set<String> value types into the shared preferences.

// Save a value in the default shared preferences.
DynamicPreferences.getInstance().save(key, value);

// Save a value in the supplied shared preferences.
DynamicPreferences.getInstance().save(preferences, key, value);

Load

It supports the retrieval of boolean, int, String and Set<String> value types from the shared preferences.

// Retrieve a value from the default shared preferences.
DynamicPreferences.getInstance().load(key, defaultValue);

// Retrieve a value from the supplied shared preferences.
DynamicPreferences.getInstance().save(preferences, key, defaultValue);

Delete

It supports the deletion of a particular key or a complete shared preferences.

// Remove a key from the default shared preferences.
DynamicPreferences.getInstance().delete(key);

// Remove a key from the supplied shared preferences.
DynamicPreferences.getInstance().delete(preferences, key);

// Delete a shared preferences.
DynamicPreferences.getInstance().deleteSharedPreference(preferences);

Dependency

It depends on the dynamic-utils to perform various internal operations. So, its functions can also be used to perform other useful operations.
