Reactor

Reactor is a fast and secure key-value library for Android, and has an embedded database based on the JSON structure and is a great alternative to Shared Preferences.

Features + Road map

First Edition 1.x.x

• Save and restore a variety of objects (serialization and deserialization)
• Symmetric encryption of objects (signed by target application at runtime + Hardware_ID)
• Very high performance‍
• Very low library size (No need for other libraries)
• Supported and tested in API 15 and above
• Minimal and easy to use :)

Second Edition 2.x.x

• Save and restore all temporary object pool at runtime in RAM
• Add a data branch (branches can be independent of the main branch)
• Imports safe data from Shared Preferences to Reactor
• ‍‍Change the underlying AES password generation
• Change the storage infrastructure
• ‍‍‍Add concurrency + thread-safe functionality

Getting Started :

Add to your root build.gradle :Ï

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

Add the dependency :

dependencies {
    implementation 'com.github.aaaamirabbas:reactor:1.5.6'
}

Simple API (default) :

In Kotlin :

val reactor = Reactor(context)
val reactor = Reactor(context, false) // disable encryption

-----------------------------------------------------------

reactor.put("firstName", "abbas")
reactor.put("lastName", null)
reactor.put("age", 23)
reactor.put("customDataClass", SampleData())

-----------------------------------------------------------

val firstName = reactor.get<String>("firstName")
val lastName : String? = reactor.get("lastName")
val isDay = reactor.get<Boolean>("isDay", false)
val customDataClass = reactor.get("customDataClass")

-----------------------------------------------------------

reactor.remove<Int>("year", "week")
reactor.eraseAllData()

In Java :

Reactor reactor = new Reactor(getContext());
Reactor reactor = new Reactor(getContext(), false); // disable encryption

-----------------------------------------------------------

reactor.put("firstName", "abbas");
reactor.put("lastName", null);
reactor.put("age", 23);
reactor.put("customDataClass", new SampleData());

-----------------------------------------------------------

String firstName = reactor.get("firstName", "abbas");
String lastName = reactor.get("lastName", null);
Integer age = reactor.get("age", 26);
SampleData customDataClass = reactor.get("array");

-----------------------------------------------------------

reactor.remove("age", 0);
reactor.eraseAllData();

Custom data class Sample :

// definition
data class SampleData(
    val id: Int = 24,
    val name: String = "abbas"
) : ReactorContract

-----------------------------------------------------------

// save, restore, remove
reactor.put("simpleData", SampleData())
reactor.get<SampleData>("simpleData") // return null if is not found
reactor.remove<SampleData>("simpleData")
