title: Android Studio 3.2 Canary 14: The following packages are not available "Package id platforms;android-28"
body: <p>Just installed new Android Studio 3.2 Canary 14 build with <em>clean config</em> to try out new AndroidX. After creating new project going to <strong>Refactor -> Refactor to AndroidX</strong> and Studio asks to upgrade <code>compileSdkVersion</code> to <strong>28</strong>. Doing the upgrade in <em>build.gradle</em> got <em>Install missing platform tools</em> and then error: <strong>The following packages are not available "Package id platforms;android-28"</strong> SDK Manager says that Platform P is partially installed (no source-code package). Update channel set to Canary, tried to completely redownload SDK - did not help. Using Mac OS High Sierra 10.13.4</p>
  
  <p>Here is <em>build.gradle</em>:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  apply plugin: 'kotlin-android'
  
  apply plugin: 'kotlin-android-extensions'
  
  android {
      compileSdkVersion 28
      defaultConfig {
          applicationId "my.app.id"
          minSdkVersion 21
          targetSdkVersion 28
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      implementation fileTree(dir: 'libs', include: ['*.jar'])
      implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
      implementation 'com.android.support:appcompat-v7:28.1.1'
