推荐答案

经过几个小时的挣扎，我通过在 app/build.gradle 中包含以下内容解决了这个问题:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

将这些标志放在你的 gradle.properties 中

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

build.gradle 的变化:

Changes in build.gradle:

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'
