Android studio could not resolve retrofit2 converter scalars 2.5.0

Android studio displays this strange error whenever I add some dependency to the grade file. It was working perfectly earlier. Further it displays no cached version of retrofit2 scalars available for offline mode.
Currently I tried almost all options from uninstalling and reinstalling android studio but no luck. I am running out of time so please help me resolve this.

Can you check, if you are under proxy and your android studio is able to connect to internet? Go to file>settings>type 'proxy' > in proxy settings there is a check connection button which will test if android studio is able to connect.
if there is a proxy, then provide the details and check again.
also make sure you do not have offline mode in your gradle settings turned on. Refer following screenshot:
Also your build tools are 4.0.1. Hope you should have the latest android studio too..

How to resolve 'com.github.d-max:spots-dialog:0.7#aar'

I have done all the solution but none of them worked. Whenever I add this library in my project. I face error like
unable to resolve this library (disable offline work option)).
After disabling it, the error come
No cached version available in offline mode(Enable offline work option)).
How I resolve it pls help

You should try this as it's stated in the documentation:
dependencies {
implementation 'com.github.d-max:spots-dialog:1.1#aar'
}
That's a newer version of the lib. I think this should solve your problem.

Error: Program type already present: com.google.firebase.database.DatabaseException

I hope someone can help me solve this error.
This is my buil.gradle (app):
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
defaultConfig {

}

}
}
packagingOptions{
exclude 'META-INF/io.netty.versions.properties'
exclude 'META-INF/INDEX.LIST'
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.google.firebase:firebase-admin:6.2.0'

implementation 'com.facebook.android:facebook-android-sdk:4.38.1'
implementation "com.google.firebase:firebase-database:16.0.4"
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.google.firebase:firebase-core:16.0.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'

annotationProcessor 'com.google.auto.value:auto-value:1.4'
implementation 'com.google.android.gms:play-services-auth:16.0.1'
}
And this is my build.gradle (Project):
buildscript {
repositories {
google()
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
The initial problem was:
More than one file was found with OS independent path 'META-INF/io.netty.versions.properties'
And to solve this I added some exclusions in the gradle.
The last working project was without the facebook plugin to log in my app.
I really need this type of login and I can't give it up.

Android Program type already present: BufferOverflowException

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.

Any help, please ?!
