Android APP - When connected it shows Blank Page

mbrizu74 · September 13, 2023, 1:18pm

Good afternoon everyone, I don’t know if it only happens to me but this is happening to me:
This week I started working with the OR sdk in Android Studio. I have the problem that I cannot connect to either the OR Demo (Smartcity and Manufacturer) or the custom implementation that I have. I tried installing and uninstalling from my Samsung A50 android phone and from Andoird Studio and I have the same error.

Android SDK August 22, 2023

I install APP
I open it and accept the policies
Enter the domain: demo
Enter the realm: smartcity
Blank screen

Is anyone experiencing the same error?

Thank you very much. Mariano.

Hi mbrizu74,

Yes, I came to this forum to look for answers. I face the same issue.

You can reproduce the issue with the Google Play app and the demo on the openremote website. Follow steps 1 to 4, but make sure in step 3 you add https://demo.openremote.app

I get in step 5 the same blank white screen even if I compiled the app myself.

A second issue, maybe entirely unrelated, is the stock app in the openremote repository on location ~/openremote/console/android/GenericApp/ does not compile. I will post the reproduction of this issue later and the “potential” fix.

Hi all!

Yes we just discovered the issue in the OR team as well.
We’re investigating and busy with working on a fix!

If you have any logs or errors to share please do!
That will help us get to the cause quicker

Hi Martin. I attach the debug of the app in Android Studio

Hi guys!

We released a new version of the OpenRemote app on the Google Play store.
The issue should be solved. Can you check?

mbrizu74 · September 20, 2023, 2:05pm

Hi Martin

It works perfect. Thank you so much. Notify when the Github repository is updated.
