Android studio 启动adb报错：...unable to start adb server,unable to detect adb version...解决

android studio 版本3.5.2

启动adb报错：...unable to start adb server,unable to detect adb version...

将sdk目录下platform-tools（v29.0.6）删除，搜索platform-tools下载旧版本（笔者此处下载的是v28.0.2）参考下载：https://download.csdn.net/download/diysoho/10646285?depth_1-utm_source=distribute.pc_relevant.none-task&utm_source=distribute.pc_relevant.none-task

下载后将platform-tools文件夹放置sdk目录下，重启android studio即可
