I see only a blank map on my HUAWEI P Smart (on Virtual device code runs normally).
Does anyone have an idea of how to solve it?

Please check authentication token for android Lite version. Also check for the permission java class that has to be correctly written. The accompanying example apps can be found on GitHub : https://github.com/heremaps/here-sdk-examples
To try out these examples, add your HERE credentials (access_key_id and access_key_secret) to the AndroidManifest.xml file, and add the HERE SDK to the libs folder.

I've seen this and this, but disabling microphone permissions and Google search app haven't solved my problem.
What should I do to fix this error?

I have this problem when I am developing a map application with a locate part in it.
It seems work fine that I could see the GPS icon on the top of the screen, however, it can't move the 'camera' to my real location.
From the log category, I found this error message 'Could not retrieve server token for package com.google.android.apps.gcs' which I thought could be the most likely reason that I couldn't get it through.
I've tried some small changes on project configuration until I tried to downgrade the compileSdkVersion to lower level. For this project, I changed it from 28 to 27. (My mobile phone is equipped with Android 9.)
Then it works.
Hope this could help you.

It's so wired, because of task invocation on ThreadExecutor. To get correct log of your issues, you should wrap action, which you submit in background with your tools (executor Service, Rx, or even AsyncTask) with try-cath block.
