问题描述

我在扩展BottomSheetDialogFragment的整个类中遇到错误

Cannot access 'androidx.lifecycle.HasDefaultViewModelProviderFactory' which is a supertype of 'FavoriteBottomDialogFragment'. Check your module classpath for missing or conflicting dependencies

该类位于app模块中,该模块实现了另外两个模块:核心和presentation-core

build.gradle

dependencies {

     implementation fileTree(dir: 'libs', include: ['*.jar'])
     implementation project (':core')
     implementation project (':presentation-core')

     implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.41"
     implementation 'androidx.appcompat:appcompat:1.1.0'
     implementation 'androidx.core:core-ktx:1.2.0'
     testImplementation 'junit:junit:4.12'
     implementation "com.google.android.material:material:1.1.0"

     //Rx
     implementation "io.reactivex.rxjava2:rxandroid:2.1.1"
     implementation "io.reactivex.rxjava2:rxjava:2.2.9"

     kapt 'androidx.lifecycle:lifecycle-common-java8:2.0.0'
     implementation 'androidx.room:room-rxjava2:2.0.0'
     implementation 'androidx.room:room-guava:2.0.0'

     implementation 'androidx.recyclerview:recyclerview:1.1.0'
     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

     androidTestImplementation 'androidx.test.ext:junit:1.1.1'
 }

     //RxJava2
     implementation "io.reactivex.rxjava2:rxjava:2.2.9"
     implementation "io.reactivex.rxjava2:rxandroid:2.1.1"
}

演示核心

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.61"
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.core:core-ktx:1.0.2'
}

BottomSheetDialogFragment

即使遇到错误,我也可以在设备中运行项目

解决方案

我今天遇到了同样的问题,并且能够解决. 原来,问题出在失败"类所在的模块所使用的androidx.lifecycle:lifecycle-viewmodel预期版本与其他一些相关代码中的后来版本之间.

因此,在我的情况下,我的模块使用的是该模块的版本 2.1.0 ,但是其中一个依赖项是在使用版本的 2.2.0 .代码不会编译,因为gradle将依赖关系解析为最新版本;但是,Android Studio对此情况感到困惑(并非总是如此,因为这种情况并非一直都发生,但是有时 –这不是我第一次看到这种情况.)

因此,解决方案是:找出您的应用程序中该库的最新版本,并为此模块更新您的build.gradle以指向gradle所解析的相同版本.或者:

  1. 运行gradlew app:dependencies
  2. 搜索lifecycle-viewmodel
  3. 的结果
  4. 在您的应用程序中更新build.gradle以依赖lifecycle-viewmodel并具有gradle表示要解析的版本
  5. 使用gradle文件同步项目

I am getting error in the whole class that extends BottomSheetDialogFragment

Cannot access 'androidx.lifecycle.HasDefaultViewModelProviderFactory' which is a supertype of 'FavoriteBottomDialogFragment'. Check your module classpath for missing or conflicting dependencies

The class is in app module and this module implements two other modules : core and presentation-core

build.gradle

dependencies {

     implementation fileTree(dir: 'libs', include: ['*.jar'])
     implementation project (':core')
     implementation project (':presentation-core')

     implementation 'androidx.appcompat:appcompat:1.1.0'
     implementation 'androidx.core:core-ktx:1.2.0'
     testImplementation 'junit:junit:4.12'
     implementation "com.google.android.material:material:1.1.0"

     //Rx
     implementation "io.reactivex.rxjava2:rxandroid:2.1.1"
     implementation "io.reactivex.rxjava2:rxjava:2.2.9"
     //Architecture component
     implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0'
     implementation 'androidx.room:room-runtime:2.0.0'
     kapt 'androidx.room:room-compiler:2.0.0'
     kapt 'androidx.lifecycle:lifecycle-common-java8:2.0.0'
     implementation 'androidx.room:room-rxjava2:2.0.0'
     implementation 'androidx.room:room-guava:2.0.0'

     implementation 'androidx.recyclerview:recyclerview:1.1.0'
     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

     androidTestImplementation 'androidx.test.ext:junit:1.1.1'
 }

core dependencies

     api "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.4"

     androidTestImplementation 'androidx.test.ext:junit:1.1.1'
     androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

BottomSheetDialogFragment

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

解决方案

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:

  1. run gradlew app:dependencies
  2. search the result for lifecycle-viewmodel
  3. update build.gradle in your app to depend on lifecycle-viewmodel with the version that gradle says it is resolving to
  4. Sync project with gradle files
