Android Studio 與 JDK 15

Question

我試圖在 Android Studio 中構建我的第一個 Android APP。 我經常使用 IntelliJ，所以 IDE 並不是全新的東西。

我下載了最新的 Studio 版本並更新了 AndroidSDK 和 NDK。 然后我創建了一個新的基本活動並將內置 JRE8 更改為我的 JDK 15.0.2。 但在那之后，它沒有建立..這是所有信息：

gradle-wrapper.properties：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0-all.zip

build.gradle：項目：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.3"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle：模塊：

plugins {
    id 'com.android.application'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 29
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_15
        targetCompatibility JavaVersion.VERSION_15
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.3.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.navigation:navigation-fragment:2.3.5'
    implementation 'androidx.navigation:navigation-ui:2.3.5'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

gradle.properties：

# Project-wide Gradle settings.
# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.

# The setting is particularly useful for tweaking memory settings.

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit

# org.gradle.parallel=true

# Automatically convert third-party libraries to use AndroidX
android.enableJetifier=true

如果我將“Version_15”更改為“Version_1_8”，則會出現此錯誤：

使用“Version_15”：

error: package android.os does not exist

（以及所有其他軟件包）

使用內置 JRE 1.8 和“Version_1_8”構建工作。 是否仍打算在 Android 中的 Java 8 中開發？ 或者我錯過了什么。

我什至沒有找到任何東西

Answer 1

顯然 Kotlin 現在是 Way-To-GO，所以我讓它保持原樣並寫在 Kotlin 中（但即使在 build.gradle 中也提到了 Java8。）
