android.annotation cannot be imported : all annotation cannot be resolved

I have some problems occur on my project which is :
android.annotation cannot be resolved.
For your information, I have migrated to androidx library. I assume that all my codes will be automatically change to androidx but only some of them changed. Current Version Android Studio is 3.5.
What have I done are
Invalidate and Restart
Clean and Rebuild
All path for sdk has been selected
The application installed on my devices, but keep stopping. Here are my details:

Remove this
implementation 'androidx.annotation:annotation:1.1.0'
implementation 'com.android.support:support-annotations:28.0.0'
and delete yours imports once and reImport
like this
import android.annotation.SuppressLint;

You should try this as it's stated in the documentation:
dependencies {

}
That's a newer version of the lib. I think this should solve your problem.

I developed an Android application on Android Studio 3.2.1 and I imported aar module to read UAE Id cards, I can run the application on my device without any problem.

When I commented

Any help, please ?!
Thank you

I'm developing my app with firebase
But I have the following problem when I made Build the project

}
allprojects {

}
task clean(type: Delete) {

I do not know if the problem is in this compile 'com.firebaseui:firebase-ui:0.6.2' I just had this problem when I added this complile
Or the problem may be related to the fact that I have multiple compiles,.
Thanks.

Change compile for implementation, compile has been deprecated.Finally, you should match the firebase version with the firebase ui version, see the github.

"Unable to merge dex" Android Studio 3.0

I read a lot other topics, but none of them helped me.
I wrote this project 2 months ago and at that time everything worked fine. Now I opened it again and it writes:
