Append at the end of the file:

1	#set path for android sdk tools

2	export PATH=$PATH:/your_android-sdk-linux_path/tools/

3	export PATH=$PATH:/your_android-sdk-linux_path/platform-tools/

The your_android-sdk-linux_path here is the absolute path

2. Save and synchronize updates

Source ~ /. Bashrc

3. If adb is directly run

Adb devices

4. Switch to root and run steps 1 and 2 again.

Then restart the adb service.

After leaving root, you can also use adb.

5. If Step 3 still does not work, refer to the following methods:

(1) plug in the mobile phone and enter the terminal:

Find your own device:

Bus 002 Device 004: ID 17ef: 6019 Lenovo
Bus 002 Device 003: ID 04c5: 1356 Fujitsu, Ltd <-------- this is my Device. Write down this line.

(2) Continue terminal Input
Sudo gedit/etc/udev/rules. d/70-android.rules

Add the following statement
SUBSYSTEM = "usb", ATTRS {idVendor} = "04c5", ATTRS {idProduct} = "1356", MODE = "0666"

(The red and green words are the ones we wrote above, respectively)

Save.

(3) terminal Input
Sudo chmod a + rx/etc/udev/rules. d/70-android.rules
Sudo service udev restart

(4) unplug the usb, re-connect it (very important), and then execute:
Adb devices
