Hello,

[react-native-bot]

Can you run react-native info and edit your issue to include these results under the Environment section?

If you believe this information is irrelevant to the reported issue, you may write [skip envinfo] under Environment to let us know.

[react-native-bot]

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

I put Appregistry on index.js

Then in app/build/build.gradle, change the entryFile from app.js to index.js

project.ext.react = [
entryFile: "index.js" // was app.js"
]

Still getting this issue.
