找不到函数androidx

找不到函数androidx

当我尝试运行应用程序时,出现以下错误

"java.lang.IllegalStateException: Function not found androidx.compose.internal.restartableFunctionInstance"

和以下警告:
C:\Users\amr\.gradle\caches\transforms-2\files-2.1\29795ea219aedbe5401209deaa0aa414\jetified-kotlin-stdlib-jdk7-1.3.60-eap-25.jar: Runtime JAR file has version 1.3 which is older than required for API version 1.4

这是我在 Activity 中的代码:
class MainActivity: AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle ? ) {
        super.onCreate(savedInstanceState)
        setContent {
            Text("Hello World")
        }
    }
}

我正在使用android studio 4.2金丝雀2

这是完整的build.gradle文件”
 apply plugin: 'com.android.application'
    apply plugin: 'kotlin-android'
    apply plugin: 'kotlin-android-extensions'

    android {
      compileSdkVersion 28

      defaultConfig {
        applicationId "com.example.myfirstCompse"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
      }

      buildTypes {
        release {
          minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
      }

      buildFeatures {
        compose true
      }



      compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
      }

      kotlinOptions {
        jvmTarget = "1.8"
      }

 composeOptions {
        kotlinCompilerExtensionVersion "0.1.0-dev09"
    }

    }

    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:1.1.0'
      testImplementation 'junit:junit:4.12'
      androidTestImplementation 'androidx.test.ext:junit:1.1.1'
      androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

      implementation 'androidx.ui:ui-framework:0.1.0-dev09'
    implementation 'androidx.ui:ui-tooling:0.1.0-dev09'
    implementation 'androidx.ui:ui-layout:0.1.0-dev09'
    implementation 'androidx.ui:ui-material:0.1.0-dev09'


    }

更新:当我将依赖版本更改为dev09时,并按照文档建议添加了compileOptions
composeOptions {
        kotlinCompilerExtensionVersion "0.1.0-dev09"
    }

它产生了以下错误:
e: java.util.NoSuchElementException: Collection contains no element matching the predicate.

最佳答案

kotlinCompilerVersion = "1.3.70-dev-withExperimentalGoogleExtensions-20200424"添加到您的composeOptions闭包中:

composeOptions {
    kotlinCompilerVersion = "1.3.70-dev-withExperimentalGoogleExtensions-20200424"
    kotlinCompilerExtensionVersion "0.1.0-dev09"
}

您肯定需要这个;我不确定是否会清除此特定错误。

您可能希望在项目级别的build.gradle文件中检查正在使用的Kotlin的版本。 1.3.70是一个已知的安全版本(它与我的代码段中的编译器插件版本相匹配)。
