Android EasyPrefs

EasyPrefs is a library for the android SharedPreferences or we can say it wrapper on it. It provides easy access to the SharedPreferences API, also it will need only one-time initialization, and is used in the whole project without context also has a facility to provide context if necessary with support encryption and decryption.

It supports all Primitive Data Types including Set.

For, the secure operation use AES encryption <= 20 API Level, and for 21 >= use Android-provided encrypted shared preferences in both cases you get the same output your key and value are stored securely.

This library is developed in Kotlin and supports both the language Kotlin as well as Java with the same practices.

The default file name is prefs_<package_name> and custom file name like prefs_<given_filename> there is no need to give a file extension. it is automatically appended at the end of the name.

Installation

Gradle:

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.kishandonga:EasyPrefs:1.2'
}

Examples

Refer, to the Sample Test Suite in the suite package For, more information refer to this test case code here

Initialize App

Prefs.initializeApp(context) this line of code adds into the main Application Class, as like this.

class MainApp : Application() {
    override fun onCreate() {
        super.onCreate()
        Prefs.initializeApp(this)
    }
}

Write Operation

Prefs.write().content("KEY", "VALUE")
      .content("KEY", "VALUE")
      .commit() or .apply()

Prefs.write(fileName)
             .content("KEY", "VALUE")
      .content("KEY", "VALUE")
      .commit() or .apply()

Prefs.write(context)
             .content("KEY", "VALUE")
             .content("KEY", "VALUE")
             .commit() or .apply()

Prefs.write(context, fileName)
             .content("KEY", "VALUE")
             .content("KEY", "VALUE")
             .commit() or .apply()

Read Operation

Prefs.read().content("KEY", "")
Prefs.read(fileName).content("KEY", "")
Prefs.read(context).content("KEY", "")
Prefs.read(context, fileName).content("KEY", "")

Secure Operation

Prefs.securely().write()
             .content("KEY", "VALUE")
             .content("KEY", "VALUE")
             .commit() or .apply()

Prefs.securely().read().content("KEY",  "")

Has Operation

Prefs.has().key("KEY");
Prefs.has(fileName).key("KEY");
Prefs.has(context).key("KEY");
Prefs.has(context, fileName).key("KEY");

Prefs.has().empty();

• Give boolean value if key exists then true else false.

Remove Operation

Prefs.remove().key("KEY").
Prefs.remove(fileName).key("KEY").
Prefs.remove(context).key("KEY").
Prefs.remove(context, fileName).key("KEY").

commit() or .apply()

• After the remove operation commit and apply call mandatory.

Clear Operation

Prefs.clear().all()
Prefs.clear(fileName).all()
Prefs.clear(context).all()
Prefs.clear(context, fileName).all()

.commit() or .apply()

Note: for, securely operation use the same Prefs.clear() operation.

• After the clear operation commit and apply call mandatory.

For, all the read, write, clear, has, remove support context and fileName manually, so you can use your preferences with multiple files with the same API use just need to change the fileName when you call.

If you pass context manually then no need to initialize lib on the application class, For, more information refer here

This library tested on the API levels 20, 26, 29, and 30 if you found any bug or issue raise an issue or submit a PR

Future Scope

• add sorting on the Set so get direct sorted data.
• callback extend as we already have in the preferences.
• provide suggestions to make this lib more helpful.
