Passing access token into app store install?

@r3mo wrote:

Hi All,

I have an ionic app that I plan to push to iOS and Android app stores. A website currently exists where users can log in (giving them an access token).

Ideally I would like to achieve a user flow where logged in users on the website can click a link to install the iOS/android app, with their access token string being passed as a parameter to App Store/Google Play store so that once they open the app, the app can automatically log them in using their access token from the website.

Questions:
[1] Is it possible to pass a parameter to the app stores and have access to this parameter on first launch?
[2] Is it secure (parameter sent over HTTPs) ?

Many thanks!

Hello Friends,

i’m new in ionic and developed an small App for our Company.
Now the App is Beta tested and we want to Publish the App with our Blackberry UEM Server.
We don’t have any problems with publishing an Android App (.apk) with the Server.
But we also tried it with an iOS App (.ipa) File.
The Upload to the UEM Server did not make any Problems.
But if any User want to install the App, it only shows an white App Icon (not ionic default icon) and the App did not start.
The .ipa File was created with xcode 10 on an Mac.
I have an Apple Developer Account activated.
What did i need to do to successful publish an iOS App with Blackberry UEM?
It’s not planned to Upload the App to the Apple Store.

Best Wishes

Ionic 4 - DevApp not fully functioning?

Hi there

I’m currently a developer on a new large scale Ionic development project, and the solution is based on Ionic 4.
We are however experiencing issues with the use of the DevApp in conjunction with Ionic 4.

Here are our findings / issues:

  • Android: Cordova is not available, giving us problems with using Advanced HTTP plugin / CORS etc…
  • iOS: Cordova is available
  • General: No console output is being captured
  • General: Not possible to remote debug webview through Chrome or Safari

These issues are really making it hard to be productive as we are faced with a long and tedious debug turnaround time :sob:

Can you shed some light on when these bugs will be fixed?

After browsing it seems like it is problem with permission related problem. However I could not get proper solution working around with this plugin. Although it is working fine for android version below 7.

let options: CaptureImageOptions = { limit: 3 };
this.mediaCapture.captureImage(options)
.then(
(data: MediaFile) => console.log(data),
(err: CaptureError) => console.error(err)
);
}

In many cases it is written fixed. However in my case it is not working. The plugin suddenly crashes the app.

Thank you by advance for any help.

How can I integrate the same layout inside the app? Could you please support me?

[Ionic 4] Checking network status over Browser

@rodrigojrmartinez wrote:

Hi Guys

I’m developing an ionic 4 app where I need to keep track of the current network status and notify the user whenever the status changes. The app should be supported on browser besides mobile devices, so after checking a while I’ve learned that when on mobile, the Network cordova plugin in should be used. This works just excellent! My problem starts when having to detect this at browser level.

Basically, what I do is to wait for the platform to be ready, check where I’m at, and based on this listen for the proper events besides checking the status at that point, something like.

constructor(platform: Platform, network: Network) {
   this.platform.ready().then(() => {
      if (this.platform.is('cordova')) {
          // this is ok
          this.listenForDeviceNetwork();
      } else {
          this.listenForBrowserNetwork();
     }
   });
}

private listenForBrowserNetwork(){
    // also tried with document!
    window.addEventListener('offline', () => { console.log('now you are offline!'); });
    window.addEventListener('online', () => { console.log('now you are online!'); });
     this.isOnline = navigator.onLine;
}

The problem I’m facing is that the navigator.onLine is always returning true, and the events are never fired. Tryied taking out the internet connection as well as setting to the airplane mode, but noting… Also tried to log the navigator.onLine with an interval and check its value, but it is always returning true

setInterval(() => {
    console.log('now ', navigator.onLine);
}, 200);

This anyone stumbled across this problem? Thanks for the time!

Now it appears that the build package process uses node 10, and now we’re getting some errors. Is there a way for us to specify which version of node we want for the build package process?

To be clear, I’m not looking for help on resolving the errors I get when it’s using node 10, I’m just asking on how to make it use node 8 instead of node 10.
