SharedPrefManager

⚡ An Android library which helps you create an Shared Preferences Manager with just annotations ⚡

In daily development, you may define SharedPreferenceshelper's for handling lightweight data storage, but every time you create a helper class you have to write a lot of boilerplate singleton code, create contract classes to have those keys saved somewhere and make getter setter every time you want to add something to it 💦 . With this library, I want to reduce that boilerplate code with help of annotations so as to reduce the errors and time while creating SharedPreferencesManager 

Gradle Setup

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

dependencies {
    implementation 'com.github.sahibedu.SharedPrefManager:Annotation:{RELEASE}'
    kapt 'com.github.sahibedu.SharedPrefManager:Processor:{RELEASE}'
}

How To Use It

Define an abstract class that contain your fields you want to save and annotate it with @SharedPrefManager

@SharedPrefManager(preferenceName = "someRandomKey")
abstract class Sample1 {
    val isFirstRunDone: Boolean = false
    val iAmNullableString: String? = null
    val iAmInteger: Int = 0
    val iAmLong: Long = 0L

    @PrefKeyInfo(key = "butIWantNewName")
    val iAmFloat: Float = 5f
}

Explaining the Annotations

• @SharedPrefManager -> It is a Class Level Annotation to be Applied on Abstract Classes. If you want to have a custom name for your preference manager then add it to preferencename field else it takes the class name as key only
• @PrefKeyInfo -> It is a Field Level Annotation used to Give MetaDataInfo To Preferences Keys. It is an optional Annotation. If you want to have a custom key for respective field then add the key to the annotation, else keys are generated based on the field name

Also Value Given to Fields Will be Taken As Default Values For Shared Pref

💥 That's All For The Code Part from Your Side To Create An SharedPrefManager 💥

Now For Using it. you just need to pass the context and thats all you require.

Sample1SharedPreferenceManager.getInstance(this)

Now you can use this and access any field with simple code like

// Getter
Sample1SharedPreferenceManager.getInstance(this).isFirstRunDone
// Setter
Sample1SharedPreferenceManager.getInstance(this).isFirstRunDone = true

If you have any suggestions or feedback let me know and we will improve this library together 😉
