Backendless.setUrl throws ExceptionInInitializer Error

Bug
1

Backendless Version: 5.2.3
Android Version: 8.0.0

Since version 5.2.3. the app initilization (Backendless.setUrl()) is not working anymore. I tested it with the generated project template downloaded from dashboard.

Exception:

Thanks, Kevin. We will investigate. Out of curiosity, why do you need to change the API endpoint URL?

Regards,

Thanks for your answer.
I just saw that this is not necessary…But then the error occurs on Backendless.initApp().

Best regards

I had reproduced the issue and created internal ticket BKNDLSS-18067 We will fix it as soon as it possible
