Android : Proguard build is failing for joda time

I am getting the following error when I build the app with proguard. This failure is new. I updated some of the libraries used in the app to latest (including the target and compile sdk version to 30)but the joda library version is not changed. It is implementation 'net.danlew:android.joda:2.8.2'
Any idea why this error is coming now and how it can be resolved.
I already have the rule -keep class org.joda.** { *; } in my progurad rules.

EDIT
Updating joda version to the latest 2.10.9.1 fixes the issue.
I am not adding this as answer as I wanted to know why this error appeared all of a sudden? Can any other version update can lead to this.

Android java.lang.ClassNotFoundException: Didn't find class

I'm a total Android newbie here, so hopefully someone can help me out.
I have an Android library (myLib.aar) that I am including/using in the HelloAR demo app.
Now, I want to use Instacapture within myLib.aar. I followed the instructions on the README:
dependencies {
...
compile "com.github.tarek360:instacapture:2.0.1"
}
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
I also tried downloading, compiling instacapture source, adding the instacapture.aar to my libs dir and modifying my Gradle files:
dependencies{
...
implementation(name:'instacapture', ext:'aar')
}
allprojects {
repositories {
...
flatDir {
dirs 'libs'
}
}
In both cases, I get the following exception:

However, if I add the dependencies to the main HelloAR app (as per the instructions in the README), the issue resolves.
Can someone please explain what is going on, why I'm getting the error, and how to resolve it without having to add the dependencies to the main HelloAR app?

Considering your quote,
I'm a total Android newbie here, so hopefully someone can help me out.
Follow these steps (in android studio) :
Go to build menu.
Clean the project by clicking on clean project.
Build the project by clicking on make project.
This process is known as clean build which is usually done after adding some dependencies.

Jacoco: IllegalStateException: Can't add different class with same name

I am trying to generate Jacoco XML reports for this Android project. I am using the gradle-android-junit-jacoco-plugin version 0.16.0 (latest as of today).
When I run the jacocoTestReportMerged task it fails with the following error:

I started configuring exclude rules such as ...
junitJacoco {
excludes = [
"**/XmlPullParsers.*"
]
}
... but then the task fails at the next file - so this does not seem to be the correct way.
I also tried 0.17.0-SNAPSHOT and version prior to 0.16.0, without success though. Gradle 6.3 is used in this project.
How can I configure the Gradle plugin for my project?

Runtime exception from room in a project that is not using room

I suddnly started getting this runtime exception at app launch without having room as my dependency at all.

here are some of the dependencies that I do have from Android arch:
implementation "androidx.core:core-ktx:$ktx_version"
implementation "android.arch.paging:runtime:$paging_runtime"
implementation("android.arch.lifecycle:extensions:$android_arc_version") {
force = true
}
implementation "android.arch.navigation:navigation-fragment-ktx:$navigation_version"
// use -ktx for Kotlin
implementation "android.arch.navigation:navigation-ui-ktx:$navigation_version"
implementation "android.arch.work:work-runtime-ktx:$work_version"
Any idea what might have caused this?

It turns out that android.arch.work:work had a dependency to the room library and I was using the version 1.0.0-alpha03 of work library. I thought of excluding the dependency but I noticed that an update is available for the work component and after trying that, it fixed the issue. So upgrade your work library to fix the issue (at this time the updated version is 1.0.0-alpha04)

Facebook Account Kit Collision with Google play services gradle

After configuring account kit sdk as
compile 'com.facebook.android:account-kit-sdk:4.+'
and gradle sync it conflict with com.google.android.gms gradle as mixing versions can lead to runtime crashes and my app crash as
Firebase API initialization failure.
java.lang.reflect.InvocationTargetException
at java.lang.reflect.Method.invoke(Native Method)
at com.google.firebase.FirebaseApp.zza(Unknown Source)
at ...
the above error is due to mixing google play services gradle (I think Google play services gradle may be used by Facebook Account Kit SDK) because I have same version for all Google play services gradles.
And one more crash is coming from Facebook Account Kit SDK side as

But after removing
compile 'com.facebook.android:account-kit-sdk:4.+'
my app working without any issue.
But to integrate Facebook Account Kit in my app I have to include above gradle which conflict with google play services.
Totally disappointed, please help.
After upgrading Firebase Gradle as
compile 'com.google.firebase:firebase-messaging:11.6.0'
its not colliding but still gives above RuntimeException from Account Kit SDK.

To fix this you can do something like the following
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'
That would remove the stale support gms library from Facebook's SDK and then swap in the same version of the lib that Firebase is using.

Possibly the conflict of libraries can be the reason. See dependencies here;
https://mvnrepository.com/artifact/com.facebook.android/account-kit-sdk/4.27.0
See if you could submit an issue with the facebook to update it.
Or if you need facebook for authentication only, you can use Facebook Android Sdk

What feature/service from firebase r u using , can u pls share the snippet of ur gradle dependencies for the same to better understand the problem here?

For Unable to get provider RuntimeException 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
