datayja/Lifecyclin

A Extension of Android Lifecycle Management for Kotlin

init {
       onStart {
           service.start()
       }
       onResume {
           service.refresh()
       }
 }

Get Started

add maven url in to your build.gradle (Normally in root project)

repositories {
    maven {
        url  "http://harrytylenol97.bintray.com/maven"
    }
}

And add library into module dependencies

<!> You should use support lifecycle library beacuse it needed

compile 'com.tylenol.library:lifecyclin:0.1.3'

Features

Add User Defined LifecycleObserver to LifecycleRegistry

First you should define class which inherits LifecycleObserver

class SampleActivith : AppCompatActivity(), LifecycleRegistryOwner {
    var myListener = MyListener()
    // ...
}

// ...
class MyListener : LifecycleObserver { /**/ }

Before

lifecycle.addObserver(myListener)

After

addObserver(myListener) // Method 1
val myListener = MyListener().registerObserver(this) // Method 2

You can also add 2 more Observers as vararg

addObserver(myListener).addObserver(myLocationListener).addObserver(myGoogleApiClientListener)
addObserver(myListener, myLocationListener, myGoogleApiClientListener)

Define Units(functions) to each lifecycle components at once (Automatically Add it as Observer to LifecycleRegistry)

init {
    onCreate { }
    onResume { }
    onPause { }
    onDestory { }
}

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    
    onResume { 
    }
    
    onPause { 
    }
    
}

Check Lifecycle Status

check current lifecycle status and return true if current status is matched

Before

if (lifecycle.currentState.isAtLeast(Lifecycle.State.CREATED)) {
  // Do something
}

After

if (isCreated()) {
  // Do something cooler
}
