我没有对Android Studio生成的模板应用程序进行任何更改。
为什么生成模板应用程序无法正常启动?
我尝试了迁移到androidX,但是问题仍然完全相同。
为什么Android Studio无法生成“干净”模板应用程序?
我的gradle文件类似于:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
