Patrons

Let your patron do the work.

A Patron is a preference wrapper. Come also with an encryption system.

Features

Use the adequate patron for the preference value type you would like to store.

Patrons handle all types handled by shared preferences:

• boolean
• float
• float
• int
• String
• StringSet

Patrons also provide an encrypted version of the shared preferences. Use patrons-conceal to encrypt your preference values.

Installation

Step 1. Add the JitPack repository to your build file

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

Step 2. Add the dependency

dependencies {
  implementation 'com.github.prolificinteractive.patrons:patron:${patronsVersion}'

  // If you want patrons with encryption of your shared preferences
  implementation 'com.github.prolificinteractive.patrons:patron-conceal:${patronsVersion}'
}

Usage

A default patron exists for all shared preferences types.

Boolean

val boolPref: Preference<Boolean> = BooleanPreference(prefs, "key")

Float

val floatPref: Preference<Float> = FloatPreference(prefs, "key")

Integer

val intPref: Preference<Integer> = IntPreference(prefs, "key")

Long

val longPref: Preference<Long> = LongPreference(prefs, "key")

String

val stringPref: Preference<String> = StringPreference(prefs, "key")

String Set

val stringSetPref: Preference<Set<String>> = StringSetPreference(prefs, "key")

Conceal

Init Conceal in your application class:

import com.facebook.soloader.SoLoader;

public class MyApplication extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, false);
  }
}

Encryption

SharedPreferences Backed Keychain

val prefs = ConcealSharedPreferences(context)

Keystore Backed Keychain

By default, preference's key is NOT encrypted but the behaviour can be customized by passing your own custom KeyEncryption

val defaultPref = PreferenceManager.getDefaultSharedPreferences(context)
val concealedPrefs = ConcealSharedPreferences(
  this,
  defaultPref,
  NoKeyEncryption(),
  ConcealEncryption(
    context,
    "conceal_encryption",
    AndroidConceal
      .get()
      .createDefaultCrypto(KeystoreBackedKeychain(context, defaultPref))
    )
)
