title: Android Studio throws "No signature of method" error, pointing to build.gradle:app
body: <p>I got this error after trying to run a Kotlin application through Android Studio:</p>
  <pre><code>A problem occurred evaluating project ':app'.
  &gt; No signature of method: build_4blexxmb1pl0fsds689m8rkwz.android() is applicable for argument types: (build_4blexxmb1pl0fsds689m8rkwz$_run_closure1) values: [build_4blexxmb1pl0fsds689m8rkwz$_run_closure1@220b09f3]
  </code></pre>
  <p>The error points me to this section of the <code>build.gradle:app</code> file (specifically, the line with <code>android {</code>):</p>
  <pre><code>android {
      compileSdkVersion 30
      buildToolsVersion &quot;30.0.3&quot;
  
      buildFeatures {
          viewBinding = true
  
          defaultConfig {
              applicationId &quot;com.example.bitfighter&quot;
              minSdkVersion 19
              targetSdkVersion 30
              versionCode 1
              versionName &quot;1.0&quot;
  
              testInstrumentationRunner &quot;androidx.test.runner.AndroidJUnitRunner&quot;
          }
  
          buildReleases {
              viewBinding = true
          }
  </code></pre>
  <p>What does this error message mean, and what can I change to fix the issue?</p>
