title: React-native debug build crash on start: Error: java.lang.NoClassDefFoundError: com.facebook.react.modules.fresco.SystraceRequestListener
body: <p>I am trying to create a debug build of my app in react-native. It worked previously and the problem started after I used react-native-tools extension package for VSCode text editor and attached its debugger for debugging. The error doesn't occur when I create a release build. I have removed the extension, removed my project node_modules folder and reinstalled.</p>
  
  <p>The error is as follows:</p>

  <p>I can't make out what the error is and how to address it. Any help is appreciated. Thanks.</p>
  
  <p><strong>Update 31/08/2018</strong></p>
  
  <p>I opened the file with the error and found that the file is available in two places:</p>
  
  <ul>
  <li><code>C:\Users\Nikhil\.gradle\caches\modules-2\files-2.1\com.facebook.react\react-native\0.12.0\8a53a72920675231a5d11880ae3cacb9ab91b93c\react-native-0.12.0-sources.jar!\com\facebook\react\modules\fresco\FrescoModule.java</code> in Users folder (Windows).</li>
  <li><code>G:\path\to\project\node_modules\react-native\android\com\facebook\react\react-native\0.55.0\react-native-0.55.0-sources.jar!\com\facebook\react\modules\fresco\FrescoModule.java</code></li>
  </ul>
  
  <p>Out of those the file in <code>Users</code> folder does not have the <code>SystraceRequestListener.java</code> file.</p>
  
  <p>Also, the react-native version in the path is 0.12.0. How is this getting set?? How do I change this?? I guess it should have been 0.55.4 i.e. current react-native version used in the project.</p>
  
  <p>Where should I do the changes?? In Project?? or in Android studio base settings??</p>
  
  <p>Please help...</p>
  
  <p><strong>Update-2 31/08/18</strong></p>
  
  <p>Removed the .gradle/cache file from <code>Users</code> folder but the error still persists.</p>
  
  <p>Now the error is definitely in the .gradle folder in the project. </p>
  
  <p>Now need to determine why the error occurs even as the <code>SystraceRequestListener.java</code> exists in the same folder as the file in which the error occurs i.e. <code>FrescoModule.java</code>.</p>
  
  <p><strong>Update 03/09/18 (3rd Sept)</strong></p>
  
  <p>I reinstalled and configured all the npm packages used in the project to find when the build gets the above error, and I found that the issue occurs when I install react-native-firebase. Will update if I find some solution.</p>
