Firebase Phone Auth is not working version 20.0.0 in android

I did update the firebase dependency to latest version as per this doc
Old dependencies
implementation 'com.google.firebase:firebase-core:17.5.1'
implementation 'com.google.firebase:firebase-analytics:17.6.0'
implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
implementation 'com.google.firebase:firebase-auth:19.4.0'
implementation 'com.google.firebase:firebase-firestore-ktx:21.7.1'
Updated dependencies
//firebase
//By using the Firebase Android BoM, your app will always use compatible versions of the Firebase Android libraries.
implementation platform('com.google.firebase:firebase-bom:26.0.0')
// When using the BoM, you don't specify versions in Firebase library dependencies
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation 'com.google.firebase:firebase-auth-ktx'
implementation 'com.google.firebase:firebase-firestore-ktx'
//The Firebase Authentication Android library now works on devices without Google Play services.
// implementation "com.google.android.gms:play-services-base:17.5.0"
old phone auth method works fine
PhoneAuthProvider.getInstance().verifyPhoneNumber(
number,
60,
TimeUnit.SECONDS,
activity,
this
)
But,after updated the dependency above method shows deprecated.so,tried this
val auth = FirebaseAuth.getInstance()
binding.fab.setOnClickListener {
val options = PhoneAuthOptions.newBuilder(auth)
.setPhoneNumber("+1 5123456788")
.setTimeout(60L, TimeUnit.SECONDS)
.setActivity(this)
.build()
PhoneAuthProvider.verifyPhoneNumber(options);
}
This error occurs when build method is called.

According to the Firebase Phone-Auth documentation, you need to enable reCAPTCHA verification
Start by adding implementation 'androidx.browser:browser:1.3.0' at build.gradle (module app) dependencies
This will make firebase to open the browser for reCAPTCHA verification.

Malcolm from Firebase here!
It looks like you're missing a set of OnVerificationStateChangedCallbacks - please call #setCallbacks() on your Builder.
I'll see if we can't get that error message to be less cryptic

The above solutions work pretty fine i.e., adding the implementation 'androidx.browser:browser:1.2.0' at build.gradle (module app) dependency, but another error occurs that it only runs on api 26 or higher.
Adding
android{
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
at build.gradle (module app) will help with lower api.

Here is my proguard configuration for room
## Room
-dontwarn android.arch.util.paging.CountedDataSource
-dontwarn android.arch.persistence.room.paging.LimitOffsetDataSource
Here are how dependencies are being declared in build.gradle
// room for local cache
implementation "android.arch.persistence.room:runtime:1.0.0"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0"
implementation "android.arch.persistence.room:rxjava2:1.0.0"
I have gone through many stackoverflow posts regarding this. Like
Room Persistence Library run time exception when calling Rooms inMemoryBuilder method
and Room cannot find implementation but thing is I am not using Kotlin and everything seems correctly configured to me. I am not sure whats the problem here please suggest.

Using Account kit gradle as
compile 'com.facebook.android:account-kit-sdk:4.27.0'
And Firebase Gradle as
compile 'com.google.firebase:firebase-messaging:11.0.4'
Note : Removing Account Kit from project its working fine i.e. there is no Firebase API initialization failure. issue. Therefore it's sure that there is conflict in firebase and Account kit SDK (:

This is caused by Facebook's SDK being packaged with a different version of the GMS library than what is packaged with Firebase's. You can do something like this to get back up and running:
compile ('com.facebook.android:account-kit-sdk:4.27.0') {
exclude group: 'com.google.android.gms', module: 'play-services-auth-api-phone'
exclude group: 'com.google.android.gms', module: 'play-services-auth'
}
compile 'com.google.android.gms:play-services-auth:11.6.0'
compile 'com.google.firebase:firebase-messaging:11.6.0'
What this does is essentially hot-swaps out the older library for the newer one packaged with Firebase. It tells Facebook to compile without the old libs and then we make sure they are added back in with newer version right after.

For NullPointerException exception it seems that, Application is not initialized first, Content Providers are initialized before it.
And in Facebook account kit SDK's code it was trying to get my application context.
Now the problem was, I did implement method getApplicationContext() in application class that is getting application shared variable but that variable was setting globally and Facebook Account Kit sdk code getting Null application context.
Solution : setting shared variable in onCreate method instead of setting globally it resolved the problem of Unable to get provider.
And For Mixing issue, Account Kit SDK use 11.0.1 version for play services gradle and in my project I am having 11.0.4 that is actually not the issue because on compile time gradle takes latest gradle but In my project I am not referring below gradle which Facebook Account Kit SDK is using.
compile 'com.google.android.gms:play-services-auth-api-phone:11.0.1'
Solution : I have added above gradle with version 11.0.4 and the mixing gradle issue has been resolved.
compile 'com.google.android.gms:play-services-auth-api-phone:11.0.4'
And as suggested by #astryk if I exclude play-services-auth-api-phone module then gradle mixing error is not showing but it is not including that module becasue in AccountKitActivity on next button click my application crashes as

Android FCM + Nearby conflict

I need both Firebase Cloud Messaging and Nearby support in my app.
The latest allowed Nearby version is 9.0.0. So, I have to use following dependencies:
//Firebase
compile ‘com.google.firebase:firebase-core:9.0.0'
compile ‘com.google.firebase:firebase-messaging:9.0.0'
//Nearby
compile ‘com.google.android.gms:play-services-nearby::9.0.0’
It compiles successfully but when I try to get Firebase instance app crashes with IllegalAccessError:
java.lang.IllegalStateException: Fatal Exception thrown on Scheduler.Worker thread.

Using of different versions for these components causes compile error. Firebase 10.0.1 without Nearby works fine but I need both.
How can I solve this issue?
Thanks.
Solution
Perhaps it's a bug but for now to ensure that play-services plugin will check available versions correctly place line
apply plugin: 'com.google.gms.google-services'
at the bottom of your build.gradle file (below the dependencies block).
Check out https://firebase.google.com/docs/android/setup#add_the_sdk

I think you are wrong the latest nearby is v10 the same as Firebase
use the following dependencies that are here under
com.google.android.gms:play-services-nearby:10.0.1
com.google.firebase:firebase-core:10.0.1
com.google.firebase:firebase-messaging:10.0.1

Conflicting HERE sdk and Fresco library

I've just stumbled upon a very particular issue. There seem to be a conflict between some native libraries (i assume). When using the HERE premium SDK for android and Facebook's Fresco library in the same project will result in HERE map not rendering. As soon as i remove the Fresco library from my project it behaves and renders as it should.
Of course the simplest solution is not to use Fresco but i rather not do that.
Anyone any idea what is going on or how to solve this?
This is the error it throws:

Seems Fresco has a file called eglconfig.xml, that file must also be present in fresco resources or in your app? If you delete this xml file from the resource tree, does it help?
/I'm from the HERESDK team and thanks for the feedback!
