java - 资源 android :attr/fontVariationSettings not found. 和 android :attr/ttcIndex not found. 错误出自何处

Question

android:attr/fontVariationSettings 未找到。和 android:attr/ttcIndex 未找到。不知从何而来的错误

我尝试将compileSdkVersion更改为28(有27个atm)，但这只会给我带来更多错误

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "package name"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 2
        versionName "2.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation fileTree(include: ['*.jar'], dir: 'libs')

将 compileSdkVersion 增加到 29。您使用的库需要最新的 compileSdkVersion。
