title: Generate signed APK - Android Failed to execute aapt
body: <p>I m trying to generate a signed APK for android with react-native. If the debug's build works well, when I try to launch the <code>./gradlew assembleRelease</code> to create the signed APK for android,  I get this error => </p>
  
  <pre><code>Task :app:processReleaseResources
  Failed to execute aapt
  com.android.ide.common.process.ProcessException: Failed to execute aapt
  </code></pre>
  
  <p>I know that I can use the <code>android.enableAapt2=false</code> flag and it works well (for create the signed APK, I tried it), but I don t want to use this options since it's just a workaround and won t works for ever, and all of the threads that I read were suggesting that... :/ </p>
  
  <p>There isn t any others options ? </p>
  
  <p>Thanks for your help !</p>
  
  <p>Log : </p>
