Hi, I was busy setting up a connection between the Orion Broker and an PLC with OPC-UA Server using the opcua iotagent agent. I managed to setup all parts and I am able to receive (test) data, but I am unable to follow the tutorial with regards to adding an entity to the Orion-Broker using a json file:

I am trying to overwrite an object inside an array called device inside my store. the mutation saveState receives a device, if it doesn't exist in device array it would push the object , but if it is already existing it will just replace it with the received device. I tried searching for a solution for almost a day and I can’t the problem with my code.

store.device.js

I run ionic cordova run android for my Ionic Cordova project. At this time, I have my mobile connected to PC via USB. So when I run that command, it installs the app on my real device Android Redmi Note 6 PRO.

But what really happens is when the app opens, only white screen appears, nothing else at all. First it shows splash screen and then white screen forever. Why does this behaviour happen? I read somewhere that some people had this problem because of Ionic 4.

Below are my logcat logs from after I click the app to open on Android emulator (it shows white screen also on Android emulator).

I am exporting a function from an external js file and trying to manipulate a Vue data bu that way but currently, I am not able to that. Here is what I tried so far :

Imported js file like this :

AFrame has a lot of cool stuff built-in, like support for controllers like gamepads.
In their documentation they recommend using the component "tracked-controls" which in turn will select the correct device component according to what is available for the browser. This seems not to work at all for me when in desktop mode in aframe v1.0.4

I'm using

• Chrome v81.0.4044.122 (windows)
• xbox gamepad
• aframe v1.0.4 (latest npm package as of writing this)

I can find the gamepad when querying the browser gamepad api directly.

I declare my entity like this:
I can then see that aframe then transform this to as explained in the docs.

In my custom component mycomponent I then want to listen for the gamepad events like so

I want to build a new App without Expo and without Yarn.

So I launched a new Projekt with react-native init and navigated inside the folder starting the Metro Server (works fine) - but when I want to start the android App on my emulator (AS Emulator) I get this Error:

In the latest (06/25/2019) update to A-frame, it seems like it is broken.

It won't even load the scene, on Chrome 75, and devtools console shows the following errors:

I am building an Android & iOS app using ionic/cordova: ionic version is : 4.11.0 & Cordova version is : 8.1.2

I created the app and tested in browser on chrome and the whole app worked fine including authorization, fetching data, etc.

My problems started when I created the android app to test. No matter what I do, I can't get the authorization workflow to redirect to the app.

Here are the things I tried:

1- callback "http/localhost" gives connection refused no matter what I tried in config.xml, cordova web view plugin, and cordova custom url scheme plugin.

2- callback "myapp://callback" gives err_unkown_url_schema" no matter what I tried modifying config.xml and using the same cordova plugins above.

I am testing on an LGG6 Android version 8.0.0. Didn't test on iOS yet.
