How...

Gradle with jitpack

Add it in your root build.gradle at the end of repositories:

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

Add the dependency

dependencies {
    kapt 'com.github.eastar-dev.EastarPreferences:pref_annotation_generator:1.0.7'
    implementation 'com.github.eastar-dev.EastarPreferences:pref_annotation:1.0.7'
}

Your code

@Pref(defaultSharedPreferences = true)
data class PPSharedPreferences(
        //@formatter:off
        val boolean1                      : Boolean,
        val string2                       : String,
        val int3                          : Int,
        val androidId                     : String,
        val appUuid                       : String
        ...
        //@formatter:on
) {
    // your init value optinal
    companion object {
        fun create(context: Context) {
            val pref = PreferenceManager.getDefaultSharedPreferences(context)
            pref.registerOnSharedPreferenceChangeListener { _, key -> Log.w(key, pref.all[key].toString().replace("\n", "_")) }
            val androidId = Settings.Secure.getString(context.contentResolver, Settings.Secure.ANDROID_ID)
            pref.edit(true) { putString("androidId", androidId) }
            pref.edit(true) { putString("appUuid", UUID(androidId.hashCode().toLong(), Build.MODEL.hashCode().toLong()).toString()) }
        }
    }
}

How used

if

data class xxxSharedPreferences{
        val string2 : String,
}

	xxx.string2 = "string" //set
	val text = xxx.string2 //get
	xxx.getString2("str")  //get with default value
