I got these errors when I try to run the emulator
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-2.4.0-runtime (androidx.lifecycle:lifecycle-viewmodel:2.4.0)
Duplicate class androidx.lifecycle.ViewModelProviderKt found in modules jetified-lifecycle-viewmodel-ktx-2.3.1-runtime (androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1) and lifecycle-viewmodel-2.4.0-runtime (androidx.lifecycle:lifecycle-viewmodel:2.4.0)
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-2.4.0-runtime (androidx.lifecycle:lifecycle-viewmodel:2.4.0)
Note: This is not specific to the android emulator but problem with gradle build.
Most likely, one of your dependencies uses the kotlin version of the viewmodel library whereas your code uses the java version.
Specify both to enforce the latest version for all dependencies:
def lifecycle_version = "2.4.0"
implementation "androidx.lifecycle:lifecycle-viewmodel:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
I had the same problem and I solved it by adding only one line of code
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.0'
Changing the viewmodel and viewmodel-ktx version to their latest version solved the problem for me :
implementation "androidx.lifecycle:lifecycle-viewmodel:2.5.1"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.1"
I thought that eliminating duplicate classes is better than adding new ones, so I'll post my solution to this problem here:
configurations {
all {
exclude group: 'androidx.lifecycle', module: 'lifecycle-viewmodel-ktx'
}
}
These lines of code need to be added to the project level build.gradle file - and the build error will go away along with the wasted memory (a bit, but still).
Strange and incomprehensible behavior. I got it after adding the Kotlin library to the project, which it was later decided to replace with a version for Java. If you go to the .gradle folder, you can find it there, but I'm not sure if removing it from there is a good idea, because it may be used in other libs. It is strange that gradle or AndroidStudio does not automatically solve this problem, because only dependencies for Java are specified in the build.gradle file.
PROBLEM: I got this error when I updated the appcompat dependency to 1.5.1.
SOLUTION: I updated the appcompat dependency to 1.6.1.
// Pick one:
// Kotlin
implementation("androidx.appcompat:appcompat:1.6.1")
// Groovy
implementation "androidx.appcompat:appcompat:1.6.1"
REASON: This works because of a bug fix implemented in 1.6.0-beta01 - therefore later versions should also work.
The 1.6.0-beta01 release notes state the following in the "Bug Fixes" section:
AppCompat now explicitly depends on Lifecycle 2.5.1 and SavedState 1.2.0. (I7e3e2)
It helped me reverting appcompat from 1.5.0 to 1.4.2 as suggested in this thread: Duplicate class androidx.lifecycle.ViewModelLazy found in modules lifecycle-viewmodel-2.5.0-runtime
I get the same error, any answers solved my issue. The key point is here to solve the error (preferences 1.2.0 in my project -> add exclude group).
def preference_version = "1.2.0"
implementation ("androidx.preference:preference:$preference_version"){
exclude group: 'androidx.lifecycle', module:'lifecycle-viewmodel'
exclude group: 'androidx.lifecycle', module:'lifecycle-viewmodel-ktx'
}
Then use 2.5.1 version for lifecycle dependencies.
def lifecycle_version = "2.5.1"
// ViewModel
implementation "androidx.lifecycle:lifecycle-viewmodel:$lifecycle_version"
// LiveData
implementation "androidx.lifecycle:lifecycle-livedata:$lifecycle_version"
// Lifecycles only (without ViewModel or LiveData)
implementation "androidx.lifecycle:lifecycle-runtime:$lifecycle_version"
// https://developer.android.com/jetpack/androidx/releases/lifecycle
implementation "androidx.lifecycle:lifecycle-viewmodel-savedstate:$lifecycle_version"
This is working fine, i hope that it will help some people !
for anyone using compose,
you just need to add
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:2.5.1"
While many of these answers will work, there is a better way to set transitive dependency versions rather than including the package as a direct dependency.
constraints {
implementation('androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.1') {
because 'insert explanation here'
}
}
Here's a breakdown https://docs.gradle.org/current/userguide/dependency_constraints.html
As directed by l33t, I added
def lifecycle_version = "2.5.1"
implementation "androidx.lifecycle:lifecycle-viewmodel:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
but put the lines in the wrong file and got
Could not find method implementation() for arguments...
Solution: Make sure you're adding these dependencies in android/app/build.gradle, not android/build.gradle. See here.
After creating a new empty Compose activity, I got this error.

Just started this error on Android build. Please help.
"Duplicate class com.google.android.gms.internal.firebase_messaging.zza found in modules jetified-firebase-iid-19.0.0-runtime.jar (com.google.firebase:firebase-iid:19.0.0) and jetified-firebase-messaging-22.0.0-runtime.jar (com.google.firebase:firebase-messaging:22.0.0)"
In build.gradle:
implementation "com.google.firebase:firebase-iid:21.1.0"
None of the answers above is correct. And none of them solves the problem.
The problem is in transitive dependencies.
You need to check which libs are causing the issue and do something like:
implementation 'com.google.firebase:firebase-messaging:22.0.0'
implementation ('com.google.firebase:firebase-iid:21.1.0') {
transitive = true
}
I resolved this problem by using the Firebase Android BoM
In my case the problem depends on the coexistence of messaging and functions.
So from this:
implementation 'com.google.firebase:firebase-messaging:22.0.0'
implementation 'com.google.firebase:firebase-functions-ktx:20.0.0'
To this:
implementation platform('com.google.firebase:firebase-bom:28.2.1')
implementation 'com.google.firebase:firebase-functions-ktx'
implementation 'com.google.firebase:firebase-messaging'
BOM 31.x does have currently this problem.
See issue here:
https://github.com/firebase/firebase-android-sdk/issues/4206
Resolved via issue here but not yet official released:
https://github.com/firebase/firebase-android-sdk/pull/4225
Comment:
it was not resolved yet, 31.0.1 only contained a fix to crashlytics crash bug. That's why this issue is still open. The team here will make a fix close the issue, then do a release likely with release notes indicating it is fixed, when it is fixed https://firebase.google.com/support/release-notes/android - here
A current workaround is to add the iid version explicitly until a new BOM version is released:
implementation platform('com.google.firebase:firebase-bom:31.0.0')
implementation 'com.google.firebase:firebase-functions'
implementation 'com.google.firebase:firebase-messaging'
implementation 'com.google.firebase:firebase-iid:21.1.0'
I encountered the same problem.
I fixed it by redefining my dependencies implementations like this:
In build.gradle:
implementation 'com.google.firebase:firebase-analytics:19.0.0'
implementation 'com.google.firebase:firebase-auth:17.0.0'
implementation 'com.google.firebase:firebase-messaging:22.0.0'
Please note my configuration in buildscript: com.android.tools.build:gradle:4.2.1
Then, clean and rebuild project.
Can you share more information about your setup?
Using react-native-push-notification ^3.1.9, I've got the same error.
To fix it :
in project/build.gradle:
buildscript {
ext {
googlePlayServicesVersion = "17.0.0"
firebaseMessagingVersion = "20.1.0"
firebaseVersion = "20.1.0"
// other settings
}
// other settings
}
in project/app/build.gradle:
dependencies {
implementation "com.google.firebase:firebase-messaging:20.1.0"
// other implementations
}
The reason : react-native-push-notification package specify dependency to firebase-messaging:+ : which ask to get the last version.
So, gradle upload the latest com.google.firebase:firebase-messaging:22.x.x which declare already existing classes in firebase-iid.
If you don't want to use firebase-bom because you don't trust firebase to keep all the proper versions in check then you can remove the duplicate.
Run ./gradlew app:dependencies (or replace app with your module)
Search for iid:19.0.0 (or whatever version is giving you issues)
Scroll up in the list to see where the library originates from.
You should see something like \--- com.google.firebase:firebase-iid:19.0.0
Keep scrolling until you find the dependency and module it originates in, marked with a + eg (+--- com.google.firebase:firebase-ml-vision)
Locate the dependency in your project and remove the duplicate iid
api("com.google.firebase:firebase-ml-vision:$version") {
exclude group: 'com.google.firebase', module: 'firebase-iid'
}
Duplicate class kotlinx.android.parcel.IgnoredOnParcel
found in modules kotlin-android-extensions-runtime-1.3.72
org.jetbrains.kotlin:kotlin-android-extensions-runtime:1.3.72)
and kotlin-parcelize-runtime-1.4.20-RC
(org.jetbrains.kotlin:kotlin-parcelize-runtime:1.4.20-RC)
I have removed kotlin-android-extensions and added kotilin-parcelize
I found the Answer
The problem was kotlin developers deprecated kotlin-android-extensions and added separate dependencies for each of them like kotilin-parcelize also they shifted the classes from
import kotlinx.android.parcel.Parcelize to kotlinx.parcelize.Parcelize
One of your dependency library is duplicating.
If you want to find the duplication dependency, you can use gradlew from Android Studio Terminal
task ':app:checkDebugDuplicateClasses'
or
you can follow
https://developer.android.com/studio/build/dependencies#resolution_errors
If you want to keep your library after you find it has duplicate references
you can check the following to exclude those
implementation ("duplicate dependency library") {
exclude(group = "org.jetbrains.kotlin", module = "kotlin-reflect")
}
for example:
implementation ("com.daveanthonythomas.moshipack:moshipack:1.0.1") {
exclude(group = "org.jetbrains.kotlin", module = "kotlin-reflect")
}
Updating AndroidStudio this week I was forced to add AnnotationProcessor:
(Don't even understand what for.)
Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration. kotlin-compiler-embeddable-1.3.11.jar (org.jetbrains.kotlin:kotlin-compiler-embeddable:1.3.11)
So I added to my app.build.gradle:
dependencies {
...
annotationProcessor "org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlin_version"
...
}
But now I can't get rid of the following errors:
Run tasks :app:checkDebugDuplicateClasses
> Duplicate class found in modules annotations-13.0.jar (org.jetbrains:annotations:13.0) and kotlin-compiler-embeddable-1.3.11.jar (org.jetbrains.kotlin:kotlin-compiler-embeddable:1.3.11)
I don't know where org.jetbrains:annotations:13.0 is declared/imported in my gradles or settings.
How can I solve this error?
I was getting a similar Gradle error stating duplicate class found in annotations when I tried to use kotlin in some Old project. In my case, I have to remove the following dependency which was causing conflict with kotlin's annotation module.
implementation 'org.jetbrains:annotations-java5:17.0.0'
I got similar error due to some libraries using different versions of the same intellij annotation library.
I run app:dependencies and found that library com.xx.yy is using intellij.annotations.12 dependency. So I exclude that for that library only with
implemenation ("com.xx.yy:1.2.3") {
exclude group: 'com.intellij', module: 'annotations'
}
./gradlew app:dependencies
check all dependencies
I am trying to implement ViewModel in a 100% Kotlin app. Every piece of documentation I can find says I want to use this to get the ViewModel instance:
ViewModelProviders.of(this).get(CustomViewModel::class.java)
According to the docs, I should be able to import this with:
import android.arch.lifecycle.ViewModelProviders
This import is unresolved though. I am using the following in my build file:
def androidArchVersion = '1.1.1'
implementation "android.arch.lifecycle:viewmodel:$androidArchVersion"
implementation "android.arch.lifecycle:livedata:$androidArchVersion"
annotationProcessor "android.arch.lifecycler:compiler:$androidArchVersion"
testImplementation "android.arch.core:core-testing:$androidArchVersion"
Why can't I access ViewModelProviders?
Include the following as a dependency:
implementation "android.arch.lifecycle:extensions:1.1.1"
The equivalent AndroidX dependency is:
"androidx.lifecycle:lifecycle-extensions:VERSION"
in where VERSION can be replaced for Current Stable, Beta or Alpha values given in this official link
This dependency is for both ViewModel and LiveData and thus would not require you to give separate dependencies for the same either; i.e. the first two dependencies indicated by you can be replaced by the aforementioned lifecycle extensions dependency.
In my case I was missing :
implementation "androidx.fragment:fragment-ktx:1.1.0"
In addition to what Sup suggested, you'll have to correct lifecycler:compiler to lifecycle:compiler - the Gradle sync shouldn't even complete successfully with this typo.
Secondly, the standard android annotation processing ("annotationProcessor") doesn't really work with Kotlin. Instead, use Kotlin's kapt.
At the top of your build.gradle file, add the following:
apply plugin: 'kotlin-kapt'.
And in your dependencies section, replace occurences of annotationProcessor (like the above one) with kapt, e.g.
kapt "android.arch.lifecycle:compiler:1.1.1"
ViewModelProviders is deprecated in 1.1.0
Check this android docs
https://developer.android.com/topic/libraries/architecture/viewmodel
I am using 2.3.1 and add below dependency in build.gradle
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1'
implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.3.1'
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
Declare ViewModel in your Kotlin code as per below:
private val cartViewModel: CartViewModel by viewModels()
Still, if you facing below error like
Unresolved reference: viewModels
Then need to add below below dependency in build.gradle
implementation 'androidx.lifecycle:lifecycle-extensions-ktx:2.2.0'
implementation 'androidx.activity:activity-ktx:1.4.0'
implementation 'androidx.fragment:fragment-ktx:1.3.6'
OR
implementation 'androidx.navigation:navigation-fragment-ktx:2.3.5'
implementation 'androidx.navigation:navigation-ui-ktx:2.3.5'
I solve this by doing like this.
implement this dependency
implementation "android.arch.lifecycle:extensions:1.1.1"
then call my ViewModel class
homeViewModel = ViewModelProvider(this).get(HomeViewModel::class.java)
I faced this kind of problem in AndroidStudio 3.0.1 and solved by adding
following dependencies in the proper build.gradle:
implementation "android.arch.lifecycle:extensions:1.1.1"
annotationProcessor "android.arch.lifecycle:compiler:1.1.1"
version code may be different as AndroidStudio tells you if it differs.
If the above "adding/updating dependecies" did not resolve your issue then try to restart your android studio. It´s just to root, I do not see any major issue with it. Hope it helps.
Resolved with this dependency for me
implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"
If someone want androidx, then, first - in build.gradle (app):
implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"
Second - in file with code:
import androidx.lifecycle.ViewModelProvider
And third - use it:
ViewModelProvider(this).get(CustomViewModel::class.java)
Or use it like this (if needed ViewModelFactory):
ViewModelProvider(this, CustomViewModelFactory).get(CustomViewModel::class.java)
Not really sure why there are soo many solutions to this problem however while none of these worked for me, I did find a solution in my case.
implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.4.1"
This can also be resolved by targeting minSdkVersion to 21.
If you have minSdkVersion 21 or higher, you won't need implementation "android.arch.lifecycle:extensions:1.1.1".
android {
kotlinOptions {
jvmTarget = '1.8'
}
}

I am using Android Room Persistence library (v.1.0.0-alpha1) in my app.
Although it is working fine, when I open model class (Kotlin Data class) in Android studio, it shows Unresolved reference for all annotations used for Room database like #Entity, #ColumnInfo etc. I tried changing version of arch library to 1.0.0-alpha5 but result was same.
In Lint inspection it is showing Remove deprecated symbol import for all imported annotations.AS was not showing this error previously.
How can I resolve this issue
Edit
Following are imports I have added in my build.gradle
compile "android.arch.persistence.room:runtime:1.0.0-alpha5"
compile "android.arch.persistence.room:rxjava2:1.0.0-alpha5"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha5"
kapt "android.arch.persistence.room:compiler:1.0.0-alpha5"
Here you have an example.
https://github.com/jsperk/PocRoom
Remember, you need add:
Gradle (Project)--> maven
Gradle (Module App) dependencies -->
implementation "android.arch.persistence.room:runtime:1.0.0"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0"
testImplementation "android.arch.persistence.room:testing:1.0.0"
implementation "android.arch.persistence.room:rxjava2:1.0.0"
In my project, I have this question cause I'm using
android.arch.lifecycle:livedata:1.1.1
than no matter using room with version 1.1.1 or 1.0.0, it still can't find the android.arch.persistence.room.Entity.
I've searched for a long time, till I found that, when I delete the LiveData implementation, the problem solved. Then I notice that, the version of these two libraries conflict. At last, I use the same version of 1.1.0 for livedata and room (since livedata have no version of 1.0.0), and solved it.
def arch_version = "1.1.0"
implementation "android.arch.persistence.room:runtime:$arch_version"
annotationProcessor "android.arch.persistence.room:compiler:$arch_version"
implementation "android.arch.persistence.room:rxjava2:$arch_version"
implementation "android.arch.persistence.room:common:$arch_version"
implementation "android.arch.lifecycle:livedata:$arch_version"
implementation "android.arch.lifecycle:extensions:$arch_version"
Adding these dependencies to your Gradle(Module App) file will solve it:-
implementation "android.arch.persistence.room:runtime:1.1.1"
annotationProcessor "android.arch.persistence.room:compiler:1.1.1"
testImplementation "android.arch.persistence.room:testing:1.1.1"
implementation "android.arch.persistence.room:rxjava2:1.1.1"
