Android Studio Chipmunk duplicate class error

I am getting the following error when Gradle is set 7.2.2.
Duplicate class androidx.lifecycle.ViewModelLazy found in modules jetified-lifecycle-viewmodel-ktx-2.3.1-runtime (androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1) and lifecycle-viewmodel-2.5.1-runtime (androidx.lifecycle:lifecycle-viewmodel:2.5.1)
Duplicate class androidx.lifecycle.ViewTreeViewModelKt found in modules jetified-lifecycle-viewmodel-ktx-2.3.1-runtime (androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1) and lifecycle-viewmodel-2.5.1-runtime (androidx.lifecycle:lifecycle-viewmodel:2.5.1)
This is not in my program but in Android Studio.
How do I correct the problem?
Thanks,
Bill

In your build.gradle try adding this:
implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.5.1"
This worked for me.
I added it but no change.
Duplicate class androidx.lifecycle.ViewModelLazy found in modules jetified-lifecycle-viewmodel-ktx-2.3.1-runtime (androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1) and lifecycle-viewmodel-2.5.1-runtime (androidx.lifecycle:lifecycle-viewmodel:2.5.1)
Duplicate class androidx.lifecycle.ViewTreeViewModelKt found in modules jetified-lifecycle-viewmodel-ktx-2.3.1-runtime (androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1) and lifecycle-viewmodel-2.5.1-runtime (androidx.lifecycle:lifecycle-viewmodel:2.5.1)

This error is caused by duplication of dependencies
To solve the same:
You must open Gradle Scripts-->build.gradle(Module: YourApp)
Or
You can just choose to search the builder:app file in Navigate--> Search Everywhere, type "build.gradle " and choose the option that appears build.gradle (: app)
Inside your build.gradle file it checks which of the implementations made in the dependencies tag was duplicated and deletes one of them.
Now
rebuild your app and good work!

Here is my build.gradle file :

apply from: 'repositories.gradle'

}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
I Tried :
Adding : configurations {compile.exclude group: 'com.google.zxing'} to build.gradle
removed the android platform from cordova and then adding it.
removed the barcodescanner plugin then adding it.
I have been stuck with this one for almost a week.

The problem was caused because of a conflict between facebook4 plugin and barcodeScanner plugin. Both use a library called ZXing which will cause a conflict.
The easy fix (hard to find) was to remove the facebook plugin and add the same one without the zxing library.
ionic cordova platform rm android
ionic cordova plugin rm cordova-plugin-facebook4 --save --variable APP_ID="ID" --variable APP_NAME="NAME"
ionic cordova plugin add https://github.com/AndreiTelteu/cordova-plugin-facebook4-no-zxing --save --variable APP_ID="ID" --variable APP_NAME="NAME"
ionic cordova platform add android
ionic cordova platform rm android
This fixed my problem. Note that there is nothing to edit in your code.
Check the git repo for more info: https://github.com/AndreiTelteu/cordova-plugin-facebook4-no-zxing

For me, the solution was to remove implementation files('libs/core.jar') from my build.gradle:
dependencies {
..........
implementation files('libs/core.jar') // Remove this line
implementation 'com.facebook.android:facebook-login:latest.release' // Conflicting with libs/core.jar.
..........
}

Duplicate class in modules dagger-1.2.2.jar and dagger-2.22.jar

After upgrading all libraries to androidx and to the latest versions of Firebase libraries
I got error with 2 different versions of dagger java files, link in the error message doesn't work. Problem occurs at step :app:checkDebugDuplicateClasses.
I do not use dagger directly in my code, using
./gradlew app:dependencies

The easiest way is to analyze dependencies.
SOLUTION #1 (console only)
Run in console:
./gradlew -q dependencies app:dependencies
After receiving list of dependencies in the console, go to Analyze part (below Solution #2).
SOLUTION #2 (generate html)
1) Add plugin to generate report
In to app/build.gradle (this with compileSdkVersion, targetSdkVersion or buildTypes), at the top add:
apply plugin: 'project-report'
near one of them:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
which are on top.
2) Generate report
Just from the console run:
./gradlew htmlDependencyReport
or from Android Studio
Tasks > other > htmlDependencyReport
3) Open report
In console you will find URL:
./gradlew htmlDependencyReport
> Task :app:htmlDependencyReport
See the report at: file:///Users/user_name/your_path/project_name/app/build/reports/project/dependencies/index.html
And go to the project ':app'
4) Analyze report
After clicking each of the position there are dependencies:
To expand all of them, you can in develper console such code:
$('#dependencies').html(function(index, html) {
return html.split('style="display: none;"')
.join('style="display: block;"')
.split('<h3 class="closed">')
.join('<h3>')
});
ANALYZE
1) Find old dependencies
In your case you are searching phrase dagger:1
Or in the console:
2) Exlude dependencies
Find in the report library name, and just exclude group from this import.
In your build.gradle (where you have all of dependencies) modify "problematic" library excluding dagger v1.
For example:
implementation("some.old.library.using.dagger1:1.0.0") {
exclude group: 'com.squareup.dagger', module: 'dagger'
}

Manifest merger error with com.google.android.material:material

I am getting following error :

andin my gradle file there is following dependencies
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.material:material:1.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.0.0'
}
I do not know what is the problem I tried multiple solution including this but did not get rid of this. Please help

It seems like a conflict between androidX and support libs.
If you are not supporting yet androidX you need to replace
implementation 'com.google.android.material:material:1.0.0' by implementation 'com.android.support:design:28.0.0'.
If you still want to use the material version, make sure your gradle.properties file has androidX and Jetifier enabled.
android.useAndroidX=true
android.enableJetifier=true
Make sure you follow the necessary setup to use material. Check it out here.

Android build error when implementing google places sdk

Hello everyone I am developing simple food delivery android application so its required to integrate google maps and auto suggestion I follow to find current location
[google sample code](https://github.com/googlemaps/android-samples/blob/master/tutorials/CurrentPlaceDetailsOnMap/app/src/main/java/com/example/currentplacedetailsonmap/MapsActivityCurrentPlace.java)
and for Auto suggestions I followed
https://developers.google.com/places/android-sdk/autocomplete
when build it gradle shows duplicate class error
Duplicate class com.google.android.libraries.places.api.internal.impl.net.pablo.AutocompletePredictionResult found in modules classes.jar (com.google.android.libraries.places:places-compat:1.1.0) and classes.jar (com.google.android.libraries.places:places:1.1.0)
Duplicate class com.google.android.libraries.places.api.internal.impl.net.pablo.AutocompletePredictionResult$StructuredFormatting found in modules classes.jar (com.google.android.libraries.places:places-compat:1.1.0) and classes.jar (com.google.android.libraries.places:places:1.1.0)

And this my gradle
implementation 'com.google.android.libraries.places:places-compat:1.1.0'
implementation 'com.google.android.libraries.places:places:1.1.0'
i try to exclude duplicate classes by below way
implementation 'com.google.android.libraries.places:places-compat:1.1.0'
implementation ('com.google.android.libraries.places:places:1.1.0'){
exclude group:'com.google.android.libraries.places.api.internal.impl.net.pablo'
exclude group: 'com.google.android.libraries.places.internal'
}
But no thing can solve my problem.

Remove
implementation'com.google.android.libraries.places:places-compat:1.1.0'
and keep only implementation 'com.google.android.libraries.places:places:1.1.0'.
Using implementation 'com.google.android.libraries.places:places-compat:1.1.0'
is neccessary only if you are using deprecated library of
implementation 'com.google.android.gms:play-services-places:16.0.0'
Please take a look here and documentation.
