I'm trying to do a QR reader with androidX and firebase, the thing is all the information about the changes is new and I'm having problems at making this app work and I think it is because of the build of the app. I'm tried different versions and libraries to use but the problem persists. One of the errors I got is

"Error: Program type already present: android.support.v4.app.INotificationSideChannel"

but there is probably some more (the debugging just mark that)

Gradle

apply plugin: 'com.android.application'

        applicationId "com.example.android.qrtest3"

                    break;

            }

        }

    }

}

The thing was I needed to fully migrate to AndroidX (

implementation 'com.google.android.material:material:1.0.0-rc01'

implementation 'com.android.support.constraint:constraint-layout:1.1.3'

implementation 'com.google.android.gms:play-services-ads:16.0.0'

importing the right things and changing

android.support.v7.app.AlertDialog to AlertDialog.
