我的设置和我试过的东西。

• JDK版本1.8

• SDK构建工具版本25

• 从Gradle构建切换到内部构建（因为内部构建会出现不同的错误）。

• 重新安装所有的东西，然后重启电脑，问题还是出现了。

Answer 1

你需要在手机程序员选项中启用usb调试功能

Answer 2

这是一个奇怪的错误，好像和Unity没有具体关系。

进程无法找到这个文件。DefaultWsdlHelpGenerator.

...'D:\Unity\TEST Game\test project\Temp\gradleOut\build\...\etc\mono\2.0\DefaultWsdlHelpGenerator.aspx' as it does not exist.

位于你的项目文件夹内的文件。D:\Unity\TEST Game\test project

作为一个不喜欢路径上有空格的人，我建议你用另一个不在路径上有空格的项目来试试，根据你的评论，这就成功了!

ps;由于这个可能对别人有帮助，我把这个写成答案!
