Page can't change in emulators

[NexusLee]

I built a cordova project.
cd demo, cordova-hcp server.
then cordova run.
Modify the index.html but the app do not change.
Am I missing anything?

[NexusLee]

And I am on windows

[NexusLee]

According to nordnet/cordova-hot-code-push-local-dev-addon#5,
I finally got the "a user connected" in the command line, but it still cant refresh automatically in the emulator.

[NexusLee]

And my chcp.json is still xxx.ngrok.com

[nikDemyankov]

As I understand, you have done everything, as described in tutorial.

1. Make sure, that https://xxx.ngrok.com/chcp.json is accessible from your emulator.
2. Make sure, that https://xxx.ngrok.com/chcp.manifest is accessible from your emulator.
3. Make sure, that paths in chcp.manifest are relative to the www folder and doesn't hold \. There might be a problem with that on windows.
4. Open your project in IDE (probably this is Android - then use Android Studio), and run it from there. Look into console for any messages from the plugin. It should log errors/success events.

Modify the chcp.json and it will change to ngrok.com at last

[NexusLee]

@nikDemyankov ngrok.com is blocked. So I change ngrok.com to my local IP in afterPrepareHook.js. But the chcp.json is still ngrok.com.

[nikDemyankov]

If ngrok is blocked - you can use some other local server, that will serve your www files, as mentioned in nordnet/cordova-hot-code-push-local-dev-addon#5.

In that case you can still use local development add-on to automatically trigger page reload. Just make sure, that config-file url is set to the correct address in your platform-specific config.xml (probably this is what you do in afterPrepareHook.js). Also, create cordova-hcp.json file in the root folder of your Cordova project, and define there:

{
  "content_url": "http://<YOUR_LOCAL_SERVER_ADDRESS>/"
}

And after each change you do - execute cordova-hcp build to refresh content of the config files in www.

[NexusLee]

I am sorry. I read your comment over and over again, but I still don't know clearly what the local server can help? I created cordova-hcp.json and I execute cordova-hcp build after each change in www. And the content_url is my local IP address in chcp.json now. Can u tell me how the local server do to www files. Thanks.

Have you checked all, what is described in #45 (comment) ?

You can get update logs from Android Studio. Just launch Android Studio, click Open an existing Android Studio project and select E:\work\cordova\demo\platforms\android. Then from it launch the app on the emulator/device and look into the logs, displayed in the studio. There you should see logs with tag CHCP. If update has failed for some reason - you should see it in there.

@nikDemyankov About this I didn't use android studio before, but finally I got this error. It's a parse error.

This means, that chcp.json is some html page, not a json config. Most likely, it's just not found on the server. That's why no update is coming.

So you need to make sure, that emulator can reach chcp.json. Open YOUR_PROJECT_DIR/platforms/android/res/xml/config.xml and check, what is set as config-file url. Then on the emulator open browser, and try to open that url. It should be a json config.

But as you have read in nordnet/cordova-hot-code-push-local-dev-addon#5 - other developer also tried to use ip as a server address, but eventually switched to some simple server, written on python. So, maybe, if ngrok is blocked for you and emulator can't reach server by ip - this is what you should try to do.
