以下是我的依赖

implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.3.0'
implementation "androidx.compose.ui:ui:1.0.0-beta06"
implementation "androidx.compose.material:material:1.0.0-beta06"
implementation "androidx.compose.ui:ui-tooling:1.0.0-beta06"
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
implementation 'androidx.activity:activity-compose:1.3.0-alpha08'
implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.0.0-beta06"

Jetpack compose过去在Artic Fox Canary上对我来说很好，但当我在Artic福克斯Beta 1上构建我的项目时，我遇到了这个错误。

Answer 1

将所有组合库更新为beta07:

implementation "androidx.compose.ui:ui:1.0.0-beta07"
implementation "androidx.compose.material:material:1.0.0-beta07"
implementation "androidx.compose.ui:ui-tooling:1.0.0-beta07"
androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.0.0-beta07"
implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"

最好使用以下内容：

ext {
compose_version = '1.0.0-beta07'
}

然后：

implementation "androidx.compose.ui:ui:$compose_version"
implementation "androidx.compose.material:material:$compose_version"
//...

Answer 2

compose编译器存在问题。仅仅更新compose库是不够的，编译器还需要至少更新到beta07。这很容易被忽略，因为它没有依赖项列表，并且在Android Studio中还没有lint突出显示。

composeOptions {
kotlinCompilerExtensionVersion "1.0.0-rc01"
}
