BuildConfig is defined multiple times, Gradle Test Build error

Type com.nikolam.nsdkelper.BuildConfig is defined multiple times: /storage/Users/Volks/Desktop/Android-2020/NsdKelper/app/build/intermediates/project_dex_archive/release/out/com/nikolam/nsdkelper/BuildConfig.dex, /storage/Users/Volks/Desktop/Android-2020/NsdKelper/nsdkelper/build/.transforms/6fff326acaa87110e65737aff5d0e0cd/classes/classes.dex
./gradlew test build outputs this
I have an App Module that implements my LibraryModule and thats it
These are the recommended fixes
This error typically occurs due to one of the following circumstances:
A binary dependency includes a library that your app also includes as a direct dependency. For example, your app declares a direct dependency on Library A and Library B, but Library A already includes Library B in its binary.
To resolve this issue, remove Library B as a direct dependency.
Your app has a local binary dependency and a remote binary dependency on the same library.
To resolve this issue, remove one of the binary dependencies.
These are the dependencies for the two build gradles of the library and the app.

I can remove the direct dependency and use JITPACK.io but I'd like to keep it local for development, I tried updating the dependencies, gradle version and downgrading versions but nothing seemed to work. I also deleted some dependencies but that didn't help either. I invalidated cache and similar common fixes but no luck.
I tried removing the dependencies from the App module and just implementing the Library(NsdKelper) but it doesn't work like the way I think it does. My way of thinking is
A implements project B which means that A will check B's dependencies and use those. But that doesnt seem to be the case here. Removing the dependencies from my App Module gives me errors of missing libraries. Or I am I misunderstanding something

They had the same Package ID, renaming the package on one of the modules solved it.

I am getting error in the whole class that extends BottomSheetDialogFragment

Even with errors i got, I can run the project in a device

I experienced this exact same problem today, and was able to solve.
Turns out the issue was a version mismatch between the expected version of androidx.lifecycle:lifecycle-viewmodel used by the module where the "failing" class is and a later version in some other dependent code.
So in my case, my module was using version 2.1.0 of this module, but one of the dependencies was using version 2.2.0. The code will compile no problem, because gradle resolves the dependency to the latest version; however Android Studio is somehow confused by this situation (not always, because this doesn't happen all the time, but sometimes – this isn't the first time I've seen this.)
Therefore solution is: figure out what the latest version of this library is in your app and update your build.gradle for this module to point to the same version that gradle is resolving to. Or:
run gradlew app:dependencies
search the result for lifecycle-viewmodel
update build.gradle in your app to depend on lifecycle-viewmodel with the version that gradle says it is resolving to
Sync project with gradle files

in my case (an Android module), Android Studio 4.0.1, I get a number of warnings in the IDE related to androidx.lifecycle.HasDefaultViewModelProviderFactory,
I have solved the issue by adding this line to build.gradle:
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
thus the beginning of build.gradle becomes:
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
...

In my case, the problem was solved adding the lifecycle viewmodel dependency in the module of the troubled class.

Add dependency into you build gradle androidx.fragment:fragment-ktx:x.x.x with actual version. For activity you must add androidx.activity:activity-ktx:x.x.x. I hope this helps you, in my case it solved the problem.

I added the following lines to build.gradle to solve the same issue in a module:
def archLifecycleVersion = '2.2.0'
implementation "androidx.lifecycle:lifecycle-extensions:$archLifecycleVersion"
kapt "androidx.lifecycle:lifecycle-compiler:$archLifecycleVersion"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$archLifecycleVersion"

Your androidx.lifecycle:lifecycle-XXX dependency versions must be the same.
in my case:
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:2.4.1"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.1"
implementation "androidx.lifecycle:lifecycle-runtime-ktx:2.4.1"

Android studio throws a duplicate class error when annotationProcessor is added

I recently just started with android development using kotlin so a total noob at android studio too.
I am trying to build a super simple HelloWorld app but I got this error:
Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration.
- jetified-kotlin-compiler-embeddable-1.3.72.jar (kotlin-compiler-embeddable-1.3.72.jar)
Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future.
See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
but when I added the annotationprocessor at the end of my dependencies like:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
annotationProcessor "org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlin_version"
}
I encountered a new error instead when I tried to build:
https://del.dog/pyfunestin

Class duplicate error can be solved by cleaning the project. First clean the project and rebuild it.

Firebase UI Database Implementation

Tried to add Firebase UI implementation
implementation 'com.firebaseui:firebase-ui-database:6.2.0'
in build.gradle file.
The following error was shown.
*ERROR: Unable to resolve dependency for ':app#debug/compileClasspath': Could not resolve com.firebaseui:firebase-ui-database:6.2.0.
Affected Modules: app*
Please guide me how to resolve the issue.
I am using Android Studio 3.5.3
Other dependencies I have already implemented in the app
implementation 'com.google.firebase:firebase-auth:16.0.5'
implementation 'com.google.firebase:firebase-database:16.0.4'

You need to update the following dependencies:
implementation 'com.google.firebase:firebase-auth:16.0.5'
implementation 'com.google.firebase:firebase-database:16.0.4'
to
implementation 'com.google.firebase:firebase-auth:19.2.0'
implementation 'com.google.firebase:firebase-database:19.2.0
Also upgrade to androidX. Check the following for more information:
From the docs:
FirebaseUI version 6.0.0 has no breaking API changes from version 5.1.0 but updates critical dependencies to new major versions.
There are two major groups of changes:
Convert all Android Support Library dependencies to AndroidX or Jetpack dependencies. For information on migrating to AndroidX see this guide.
Update all Firebase and Google Play services dependencies to their latest major versions. For information on changes included in these SDKs visit the release notes.

You can follow these steps:
Press F4 to open Module settings
Select Dependency
Click Add new dependency
Type firebase, search for firebase.ui and add its latest dependency.

At last I was able to sync successfully without Error.
The final dependencies in the build.gradle file of the app.
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

AndroidX Q material component not working

I have just started a new project with the latest version of Android studio 3.5.2. Min API - 19 and using SDK Q, which forces us to use AndroidX.
com.google.android.material.textfield.TextInputLayout
Giving error: Android resource linking failed.
With this setup, I am trying to user Material Component, but it is not working.
I am not sure if anything changed in AndroidX or Material component is already included or not. However, I have added the material dependency anyway.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
// here is the one
implementation 'com.google.android.material:material:1.2.0-alpha01'
}
So my issue is how can I use material components on this setup.
