HCP works on browser, but not on Android app

1

I have server and app built on meteor 1.8.1.

When I build the server with changed content in the public folder, if I had any browser open on the server URL, it refreshes and shows the updated public content.

But, android apps do not detect the update. Even if I close, run or uninstall+install, the app never detect update.

I have done a full meteor uninstall, install, reset, remove platform, add platform etc. Nothing works.

I have also added the “meteor add cordova:cordova-plugin-meteor-webapp@1.7.0”

Android log shows some errors like cordova.js not found in bundle etc.

The app works perfectly though. Just the HCP does not work on public folder content change.

I tried calling WebAppLocalServer.checkForUpdates(); manually. But I can see this exception:

The app is definitely connected to the server. I can call APIs on the server. So, the server is running and receiving calls from the apps.

Can you confirm that your manifest is not being cached when you upgrade your code?

website.com/__cordova/manifest.json

Also check that your manifest has the correct format

Well remembered @rjdavid.

@oazabir, check out this thread: https://github.com/meteor/meteor/issues/10277. You’ll see at the bottom of that thread that I had accidentally introduced a WebApp.rawConnectHandlers.use call which added a cache-control header to all .json files.

A quick test for this is as @rjdavid suggests - open the manifest.json file directly in Chrome and look at the repsonse headers to see if there are any cache-control headers.

In my case iOS was obeying the headers (breaking HCP) and Android was ignoring the headers (allowing HCP), but your experience here is the opposite. Your subject line states that HCP isn’t working in Android. What about iOS?

Thank you for looking at this issue. I found that I needed to add android platform on the server, in order for the __cordova endpoint to be generated. Now that solves the initial problem. I have a new problem now.

Error: appId in downloaded asset bundle does not match current appId. Make sure the server at https://app.quranerkotha.com/ is serving the right app

This error comes from WebAppLocalServer.checkForUpdates() call.

I can see the __cordova/manifest.json is generating unique appId, which is probably not matching with the appId specified in the app in mobile-config.js.

How can I fix the appId in __cordova/manifest.json?

OK, I found the way to set APP_ID environment variable. Now, the server side has got a fixed App Id.

Problem is now with Androind app build. It is getting random App ID generated.

console.log("Application startup: " + meteor_runtime_config.appId);

Shows randomly generated app ID. How do I fix this?

I have tried passing --mobile-settings to meteor build command, hoping it would take the mobile-config.js and apply the App Id from there. But doing that gives me this error during build:

While processing mobile-config.js:
<anonymous>: Unexpected token A in JSON at position 0

The js file is definitely valid.
