title: Firebase Crashlytics Minify R8 Android
body: <p>The app works fine under normal instances but when I try to implement minify and R8. This raises the following error.</p>
  <pre><code>* What went wrong:
  Execution failed for task ':app:uploadCrashlyticsMappingFileAlpha'.
  &gt; Failed to calculate the value of task ':app:uploadCrashlyticsMappingFileAlpha' property 'googleServicesResourceRoot'.
     &gt; Could not get unknown property 'intermediateDir' for task ':app:processAlphaGoogleServices' of type com.google.gms.googleservices.GoogleServicesTask.
  </code></pre>
  <pre><code>* Exception is:
  org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:uploadCrashlyticsMappingFileAlpha'.
  
  //..... More Error Line
  </code></pre>
  <p>I get the above error and
  Absolutely have no idea what's happening.</p>
  <pre><code>buildTypes {
          getByName(&quot;debug&quot;) {
              applicationIdSuffix = &quot;.sandbox&quot;
              debuggable true
          }
          alpha {
              minifyEnabled true
              shrinkResources true
              proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
              versionNameSuffix &quot;.alpha&quot;
          }
  }
  </code></pre>
