I am using a number of DialogFraments in my Android app. To set up, I have imported "androidx.fragment.app.DialogFragment;" into each DialogFragment class. I have not added the Fragment dependency to the app's build.gradle file and the app is stable, working fine and the DialogFragments load and dismiss as expected.
Since DialogFragment extends Fragment though, should I be adding the below AndroidX Fragment library into the project's build.gradle file? If yes, what is the benefit of adding this dependency since the app is working fine now without it?
build.gradle
dependencies {
def fragment_version = "1.5.5"
implementation "androidx.fragment:fragment:$fragment_version"
}
Existing build.gradle (:app)
dependencies {
def room_version = "2.4.3"
def lifecycle_version = "2.2.0"
def work_version = "2.7.1"
implementation fileTree(dir: 'libs', include: ['*.jar'])

}
If you already use fragments you apparently already have dependency that supports it, so no need to add another one.
You can post your gradle file so we can see which dependencies you already have.

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:$archLifecycleVersion"
Your androidx.lifecycle:lifecycle-XXX dependency versions must be the same.
in my case:
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:2.4.1"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.1"
implementation "androidx.lifecycle:lifecycle-runtime-ktx:2.4.1"
This question already has answers here:
ViewModel in Kotlin: Unresolved Reference
(12 answers)
Closed 2 years ago.
I just started an Android App and I want to use ViewModel. I looked into documentation and I put all the dependencies from Lifecycle but when i try to instantiate a view model like this viewMyViewModel by viewModels() i get this error 'Unresolved reference: viewModels()'.
These are the dependencies:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$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:4.13'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
def lifecycle_version = "2.2.0"
def arch_version = "2.1.0"
implementation "android.arch.lifecycle:extensions:1.1.1"
kapt "android.arch.lifecycle:compiler:1.1.1"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-runtime-ktx:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-viewmodel-savedstate:$lifecycle_version"
kapt "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-service:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-process:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-reactivestreams-ktx:$lifecycle_version"
testImplementation "androidx.arch.core:core-testing:$arch_version"
}
Include this in your dependency,
implementation "android.arch.lifecycle:extensions:1.1.1"
then, add apply plugin: 'kotlin-kapt' in build.gradle
then add,
kapt "android.arch.lifecycle:compiler:1.1.1"
Replace other annotationProcessor with kapt
See if it works or not, if not, then go to
file -> invalidate cache and restart
After refactoring dependencies to androidx dependencies with android studio I keep getting errors when building. I looks like the application still uses the old depedencies, but I have tried to clean projekt and rebuild project... nothing helped.
Below is the dependencies I use in my application.

I migrated my android Application to AndroidX (From menu Refactor-> Migrate to androidX), Now When I run the application it's working fine but when I try to generate signed .apk file I am getting an error like
Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzcdb.
Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzii.
Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzcms.
Here is the List of dependencies I am using on my application,
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:29.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}
implementation project(":photoview")
implementation 'com.google.android.gms:play-services:12.0.1'
implementation 'com.google.firebase:firebase-messaging:20.0.0'
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'
implementation 'com.google.android:flexbox:0.3.2'
implementation('com.crashlytics.sdk.android:crashlytics:2.10.1#aar') {
transitive = true;
}
}
This is likely the cause of your problem:
implementation 'com.google.android.gms:play-services:12.0.1'
In fact, this dependency is very out of date. You should actually just remove it completely and let firebase-messaging just pull in what it needs.
If you need to use any specific play-services library, you should use one of the new, more granular ones listed here:

I have made the following changes to my build.gradle(app) file.
apply plugin: 'kotlin-kapt'
and
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.core:core-ktx:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha05'
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha07'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0-alpha01'
kapt 'androidx.lifecycle:lifecycle-compiler:2.0.0-rc01'
implementation 'androidx.room:room-runtime:2.1.0-rc01'
kapt 'androidx.room:room-compiler:2.0.0-rc01'
implementation 'androidx.paging:paging-runtime:2.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation 'io.sentry:sentry-android:1.7.16'
implementation 'org.slf4j:slf4j-nop:1.7.25'
}
And now the Kotlin compiler is throwing the following error about my EntryDAO.kt and EntryDatabase.kt files:
The error message is quite clear.
The room’s Delete, Update methods signature has changed. It needs to return void or int.
Edit: I checked again, your gradle file mixed androidx library and pre-AndroidX versions of Lifecycle.
