我不知道从这里该怎么办。我试过世博会，那是另一个兔子洞。。。有人请帮忙！谢谢 Android Studio>首选项>外观和行为>系统设置>Android SDK 勾选最新的Android版本，单击应用 此时Android将要求您同意其许可证，并将安装更新版本
Android Studio>首选项>外观和行为>系统设置>Android SDK 勾选最新的Android版本，单击应用 此时Android将要求您同意其许可证，并将安装更新版本 我读了一个答案（谢谢），但遗憾的是它没有起作用。我现在认为许可证不再是问题。我意识到这个项目需要安卓27，我已经安装了安卓28，所以我尝试降级到安卓27。这不起作用，所以我只是（我认为）将android/build.gradle中的ext改为：
ext {
buildToolsVersion = "28.0.0"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 26
supportLibVersion = "28.0.0"
}
packagingOptions {
