fix error: device not found

Posted 2020-06-21 fangtest

1、通过apt-get安装adb (若已经配置，可跳过)

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb

将android设备连接至电脑，执行adb shell会提示“error: device not found”

2、手机先不连上点电脑，通过lsusb查看usb设备，再把android设备连接至电脑，通过lsusb查看usb设备，多出多那一行就是Android设备。

Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 003 Device 009: ID 18d1:4e12 Google Inc. Nexus One (debug)

Bus 003 Device 004: ID 17ef:6018 Lenovo
Bus 003 Device 005: ID 17ef:6019 Lenovo
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

3、创建adb_usb.ini文件，写入id

echo 0x18d1> ~/.android/adb_usb.ini

4、添加权限

sudo vim /etc/udev/rules.d/70-android.rules

加入以下内容，注意红色部分对应的就是lsusb得到的id

UBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e12",MODE="0666"

5、重启USB服务

$sudo chmod a+rx /etc/udev/rules.d/70-android.rules
$sudo service udev restart

6. 重启adb服务，adb devices有设备说明adb安装成功

$adb kill-server

$sudo adb start-server

$adb devices
