UIExplorer example fails to build (again)

[edward-at-intelex]

Hello,

• I was following the instructions to set up the react-native examples (UIExplorer, Movies etc.) pulled from GIT.
• I am attempting to set it up to preview the examples via the Genymotion Android Simulator on a Mac.
  *All previous steps regarding setup, pulling the repo, etc. are successful with no errors.
  *I then execute the following statement at the bash shell on Mac

./gradlew :Examples:UIExplorer:android:app:installDebug

The following error is shown while building.

... (did not want to put the whole stacktrace unless you want it)

All the types of errors indicate that UIExplorerActivity.java has an error onPause() and onResume() while compiling.

I have already looked at similar issues on this list, including

• https://github.com/facebook/react-native/issues/5790
• https://github.com/facebook/react-native/issues/4858

But they do not appear to be related to this issue (as it is a different class that is failing even though the error result might be the same.

Notes: building the iOS version works fine (with xCode etc.).

How to fix this? Any insight appreciated. thanks..

Are you sure you have the latest version? I fixed this a few days ago in ad17a2f.

[edward-at-intelex]

Hi @janicduplessis I pulled last week, February 19th it looks like. Did you update it since then? Would you suggest I pull again and go through the steps?

[janicduplessis]

Yes, it was fixed 2 days ago. You can just pull again and it should work.

[edward-at-intelex]

Hello @janicduplessis ,

Thanks for your response. I pulled the latest build from gitHub (via git pull). I was able to proceed with invoking the following lines

./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh

note I replaced Movies with UIExplorer, of course.

but when launching the app in the genymotion simulator I get the following error in the sim:

and the terminal log shows the following information below.

TypeError: _this2._depGraph.createPolyfill is not a function

doing a search for createPolyfill here in the issues threads doesn't reveal anything. Let me know how to proceed from here.

thanks

Edward

[edward-at-intelex]

Hi there - in addition, I did check index.js as well, and it does seem that createPolyfill() is not actually defined there...I looked up the declaration of _depGraph and this is what I see initially:

`
this._depGraph = new DependencyGraph({

  activity: Activity,

  roots: opts.projectRoots,

  assetRoots_DEPRECATED: opts.assetRoots,

  assetExts: opts.assetExts,

  ignoreFilePath: function(filepath) {

    return filepath.indexOf('__tests__') !== -1 ||

      (opts.blacklistRE && opts.blacklistRE.test(filepath));

  },

  providesModuleNodeModules: [

    'fbjs',

    'react',

    'react-native',

    // Parse requires AsyncStorage. They will
    // change that to require('react-native') which
    // should work after this release and we can
    // remove it from here.

    'parse',

  ],

  platforms: ['ios', 'android'],

  preferNativePlatform: true,

  fileWatcher: opts.fileWatcher,

  cache: opts.cache,

  shouldThrowOnUnresolvedErrors: (_, platform) => platform === 'ios',


});`

not sure if that helps, but let me know if you need other info - or maybe this should be pushed to a new thread/discussion (as its not related to building the examples)

Hi @edward-at-intelex,

Updating your node-haste module to 2.3.0 will solve the problem (see b41ad9f).

[edward-at-intelex]

@Kureev thank you, I have updated node-haste. it appears to be working now. someone should update notes at some point :)

have a great day.
