Xpref

A SharedPreferences' wrapper that truly supported sharing data across multi-process

Principle

ContentProvider is designed to provide content between multiple applications that means it supported sharing data between multi-process. Use it to wrap the SharedPreferences can make the latter truly cross-process sharing data

Usage

Add dependency to your gradle script:

dependencies {
    implementation 'com.bilibili.lib:x-pref:1.2'
}

Note that this library is written with kotlin 1.2.10.

1. Gets the default SharedPreferences which is typically used in the Settings of an APP.

Xpref.getDefaultSharedPreferences(context)

2. Gets a SharedPreferences with specific named.

val name = "awesome"
Xpref.getSharedPreferences(context, name)

3. Extension in Kotlin.

You can declare extension functions in somewhere on your need for better convenience usage like following:

fun <T: ContextWrapper> T.xpref() = Xpref.getDefaultSharedPreferences(this)

fun <T: ContextWrapper> T.xpref(name: String) = Xpref.getSharedPreferences(this, name)

// in Activity
class AnActivity : Activity() {
    private fun getPreferences() = this.xpref("awesome")
}

// in Service
class AService : Service() {
    private fun getPreferences() = this.xpref("awesome")
}

The other usage is the same as normal SharedPreferences.

Have fun!
