MMKV-KTX

English | 中文

License

It's easier to use the MMKV without initializing the MMKV and defining the Key value.

Usage

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

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

Add dependencies in your module build.gradle :

dependencies {
    implementation 'com.github.DylanCaiCoding:MMKV-KTX:1.2.11'
}

Create a class to implement the MMKVOwner interface and delegate properties to MMKV with the by mmkvXXXX() method, for example:

object DataRepository : MMKVOwner {
  var isFirstLaunch by mmkvBool(default = true)
  var user by mmkvParcelable<User>()
}

Setting or getting the value of the property calls the corresponding encode or decode method, and the key value is the property name.

The following types are supported:

Method Default value
mmkvInt() 0
mmkvLong() 0L
mmkvBool() false
mmkvFloat() 0f
mmkvDouble() 0.0
mmkvString() /
mmkvStringSet() /
mmkvBytes() /
mmkvParcelable() /

You can get the kv object in the implementation class of MMKVOwner to delete values or clear all, for example:

kv.removeValueForKey(::user.name)
kv.clearAll()

If different modules/logics need isolated storage, you can override the kv to create your own MMKV instance separately:

object DataRepository : MMKVOwner {
  override val kv: MMKV = MMKV.mmkvWithID("MyID")
}

See the unit test code for the full usage.
