前言

当前PC连着多个安卓设备时，当超出了 adb 所支持的设备数，步骤如下:

• adb devices 列出你当前的设备列表，然后拷贝你要安装的设备Device Id； 使用 adb -s deviceId
• install .... 来进行 APK 安装

error: more than one device/emulator
adb: error: failed to get feature set: more than one device/emulator
- waiting for device -
error: more than one device/emulator

效果图

在这里插入图片描述
