title: How do you fix the following error : A problem occurred evaluating project ':app'. > No signature of method:
body: <p>I am getting the following error when trying to run my react-native app with android and I am unsure why, any ideas?</p>
  <p>*Where:
  Build file '/Users/ahmeeyagoldman/Documents/TikTok/android/app/build.gradle' line: 123</p>
  <ul>
  <li>What went wrong:
  A problem occurred evaluating project ':app'.</li>
  </ul>
  <blockquote>
  <p>No signature of method: build_26i9j525hbm41pwpexiy08g68.android() is applicable for argument types: (build_26i9j525hbm41pwpexiy08g68$_run_closure1) values: [build_26i9j525hbm41pwpexiy08g68$_run_closure1@6ee8b6f5]
  My build.gradle file:</p>
  </blockquote>
  <p>So far I have tried to:</p>
  <ul>
  <li>upgrade and downgrade my gradle,
  -clean and rebuild the project,
  -Invalidate caches/Restart,
  -Comment out new lines of code,</li>
  <li>Edit my configuration (didn't change much)</li>
  </ul>
  <p>I can get an android application to run using react-native if I try another project but this one is throwing errors. Something to note I am not sure if it matters but this is connected to AWS.</p>
