Which version of RN/CodePush/iOS are you running? We will try to look at this within the next two days.

@xlj44400, @iZaL - which versions of RN, CodePush, and iOS are you seeing this on?

[richardhuaaa]

@xlj44400, @iZaL - I think I've found the code causing the problem and fixed it in #526.

The bug was merged into master but not yet released to npm. Can you confirm that you found this issue while running the CodePush version on our master branch, possibly with the example app? We've traditionally done most of our testing before npm releases, but in future we will aim to do more up-front so that our master branch is stable.

Also, note that once you've synced to the latest commit, you'll need to delete the react-native-code-push folder in your app's node_modules (rm -r <AppName>/node_modules/react-native-code-push), and then run npm install again, because npm doesn't automatically detect changes in local file dependencies.

Is this supposed to be fixed in 1.16.1-beta ?

[sergey-akhalkov]

@hojberg - hi! Changes probably fixing the issue are already in CodePush.m and package-mixins.js files belong to react-native-code-push having version 1.16.1-beta.

[jaggerwang]

Still there!

codePush.sync({deploymentKey});

I'm using pull #670 , because my RN version is 0.40.0.

[sergey-akhalkov]

@jaggerwang - hi! I've got the same warning while using react-native@0.40.0 and react-native-code-push@1.17.0-beta, so I've started investigation.

@sergey-akhalkov Just to confirm or chime in. I'm new to CodePush but I have the same error running react-native@0.40.0 and react-native-code-push@1.17.0-beta.

I was following the Plugin Usage guide (awesome docs btw, good job!). Fetching a new bundle works on app restart but it doesn't work on app resume.

// Works correctly after app restarts
MyApp = codePush(MyApp);

// Doesn't work on app resume, but I may be missing or doing something wrong
let codePushOptions = { checkFrequency: codePush.CheckFrequency.ON_APP_RESUME };
MyApp = codePush(codePushOptions)(MyApp);

Update 2017-02-09: Updating works correctly on app resume, second code snippet was me simply misunderstanding the updating mechanism. Implementing the codePushDownloadDidProgress() method silenced the errors. Thanks @sergey-akhalkov!

[sergey-akhalkov]

@jaggerwang, I've found the place where the warning occurs: https://github.com/facebook/react-native/blob/master/React/Modules/RCTEventEmitter.m#L54
It happens when there are no event listeners registered for CodePushDownloadProgress event.
So to go it away you could just implement realization of codePushDownloadDidProgress method:

export default class myapp extends Component {
  codePushDownloadDidProgress(progress) {
        console.log(progress.receivedBytes + " of " + progress.totalBytes + " received.");
  }
  ...
  }
}

Please let me know if there are any issues like this one
