一、报错信息

更新了 Android Studio 到 4.2.1 , 打开之前的老项目 , 部分界面是由 Kotlin 开发的 , 进入 Kotlin 开发的界面报错 , 进入 Java 开发的界面正常 ;

此外 , Kotlin 升级到了 1.5.0 ;

Android Studio 4.2.1 编译报错 , 凡是调用到 Kotlin 的 Activity 界面 , 都爆如下异常 ;

Java 代码的 Activity 正常运行 ;

二、解决方案

创建一个最新的应用 , 查看具体的配置与老项目的配置区别 :

plugins {
    id 'com.android.application'
    id 'kotlin-android'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:2.0.4'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

发现在 Module 下的 build.gradle 构建脚本中 , " android " 层级下 , 配置如下选项 ;

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = '1.8'
}

将上述配置配置到老项目的 " android " 层级下 , 编译通过 ;
