类android.graphics.Typeface在库根文件夹

下可见

用途：

'com.android.tools.build:gradle:3.2.0-alpha14'

compileSdkVersion 27

buildToolsVersion "27.0.3"

有什么想法吗？

Answer 1

目前，成功构建是使用以下版本的SDK和buildTools

buildToolsVersion "28.0.0-rc2"

compileSdkVersion 'android-P'

从support库迁移到androidx

def x_version = '1.0.0-alpha1'
def x_constraint_version = '1.1.0'
dependencies {
   implementation "androidx.recyclerview:recyclerview:$x_version"
   implementation "androidx.appcompat:appcompat:$x_version"
   implementation "androidx.constraintlayout:constraintlayout:$x_constraint_version"
   implementation "androidx.coordinatorlayout:coordinatorlayout:$x_version"
   implementation "androidx.cardview:cardview:$x_version"
}
