Reproduction

Follow the steps in the Getting Started guide for Android and create a new project called AwesomeProject and then run the application in the emulator.

Solution

So far I am not able to resolve the issue. I tried npm install and made sure I had the latest react, but nothing fixes the issue. I also tried with different Android API versions (23, 25). I previously had another project that was working under 0.37 but that project has the same error
after upgrading the project to 0.39.2.

Additional Information

• React Native version: 0.39.2
• Platform: Android
• Operating System: MacOS (Sierra)

Restarting packager fixed the issue.
