2 安装 adb

使用命令行工具 sdk-manager, 需要给 --sdk_root 指定一个当前用户有权限的目录

$./sdk-manager "platform-tools" --sdk_root=/home/software/androidsdk

3 使用 adb 连接手机

用 USB 连接手机和电脑

$./adb devices
List of devices attached
XXxxXxxxxxxx	no permission

解决方法:
1 . 使用 lsusb

$lsusb
...
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 023: ID 0a5c:21f3 Broadcom Corp. 
Bus 001 Device 022: ID 2717:003b  
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 066: ID MYID:myid Google Inc. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

2 . 在 /etc/udev/rules.d/ 下新建 51-android.rules 文件.

SUBSYSTEM=="usb", ATTRS{idVendor}=="MYID", ATTRS{idProduct}=="myid",MODE="0666"

权限设置为 sudo chmod a+x 51-android.rules

这时:

$./adb devices
List of devices attached
XXxxXxxxxxxx	unauthorized

只需要在手机上确认一下允许USB调试就可以正常 attach 手机了，状态如下：

$./adb devices
List of devices attached
XXxxXxxxxxxx	device

3 使用网络连接手机

手机和电脑在同一个局域网.
使用手机 IP, 让手机监听端口 5555

$./adb tcpip 5555
$./adb connect 192.168.1.5:5555

查看

$./adb devices
List of devices attached
XXxxXxxxxxxx	device
192.168.1.5:5555 device

然后去掉 USB

$./adb devices
List of devices attached
192.168.1.5:5555 device

4 使用投屏软件 scrcpy

安装 snap
sudo dnf install snap
从 snap 安装 scrcpy
snap install scrcpy

指定安装的 adb 路径, 运行 scrcpy。 适用 WIFI 的折衷参数 --bit-rate 2M --max-size 800

$ ADB=/home/software/androidsdk/platform-tools/adb scrcpy --bit-rate 2M --max-size 800 --serial 192.168.1.5:5555
