title: How to get lifecycle.coroutineScope with new androidx.lifecycle:*:2.2.0-alpha01
body: <p>On 7th May, 2019 <code>androidx.lifecycle:*:2.2.0-alpha01</code> was released announcing:</p>
  
  <blockquote>
    <p>This release adds new features that adds support for Kotlin coroutines for Lifecycle and LiveData. Detailed documentation on them can be found here.</p>
  </blockquote>
  
  <p>On <a href="https://developer.android.com/topic/libraries/architecture/coroutines#lifecyclescope" rel="noreferrer">documentation</a> it's mentioned that I can get the <code>LifecycleScope</code>:</p>
  
  <blockquote>
    <p>either via <code>lifecycle.coroutineScope</code> or <code>lifecycleOwner.lifecycleScope</code> properties</p>
  </blockquote>
  
  <p>But it seems that I'm not able to find none of them. My current dependencises are:</p>
  
  <pre><code>def lifecycle_ver = "2.2.0-alpha01"
  implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_ver"
  implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_ver"
  implementation "androidx.lifecycle:lifecycle-common-java8:$lifecycle_ver"
  
  implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.2.1'
  implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.2.1'
  </code></pre>
  
  <p>What may be the cause and how do get these apis?</p>
