Foreword

adb, full name  Android Debug Bridge, Android command line debugging tools, it has a variety of functions, such as tracking system logs, upload  and download files, install applications.

Prepare

Connect the device with the data cable (the underlying USB interface) and the host as shown.
In the development board , enter: Settings-> USB, check the "Connect to PC" option.

ADB Install for Windows

First of all,  install driver refer to the installation of RK USB driver section.

donwload adb.zip from the website http://adbshell.com/download/download-adb-for-windows.html，then unzip it in path C:\adb to call it conveniently。

Open a command line window and input:

cd C:\adb
adb shell

If everything is normal, you can enter the adb shell, and run some commands.

ADB Install for Ubuntu

• Install adb tool：

sudo apt-get install android-tools-adb

• Add device ID:

mkdir -p ~/.android
vi ~/.android/adb_usb.ini
# add the following line:
0x2207

• Add udev rules：

sudo vi /etc/udev/rules.d/51-android.rules
# add the following line：
SUBSYSTEM=="usb", ATTR{idVendor}=="2207", MODE="0666"

• Reseat the data cable Type-C or run the following command to make the udev rule take effect:
  

sudo udevadm control --reload-rules
sudo udevadm trigger

• Restart adb server
  

sudo adb kill-server
adb start-server

Commonly Used ADB Command

Connection management

List all connected devices and their serial numbers

adb devices

If there are multiple connected devices, you need to use the serial number to distinguish:

export ANDROID_SERIAL=<device serial number>
adb shell ls

Adb can be connected via the internet:

# Allow adbd restart on the device side and listen on TCP port 5555
adb tcpip 5555
# Type-C connection can be disconnected at this time
# Connect to the device remotely. The IP address of the device is 192.168.1.100
adb connect 192.168.1.100:5555
# Disconnect
adb disconnect 192.168.1.100:5555

Debug

Get system log adb logcat

• usage
  

adb logcat [option] [Application label]

• example
  

# View all logs
adb logcat
# View only part of the log
adb logcat -s WifiStateMachine StateMachine

run: adb shell

Get detailed operating information: adb bugreport

adb bugreport is used for error reporting, which contains a wealth of useful information.

• example

adb bugreport
# Save to local, make it easy to use editor view
adb bugreport >bugreport.txt

Application Management

use adb install to install apk

• usage：

adb install [option] example.apk

Options include：

-l forward-lock
-r Reinstall the application to retain the original data
-s Install to SD card instead of internal storage

• example：

# install facebook.apk
adb install facebook.apk
# upgrade twitter.apk
adb install -r twitter.apk

If install sucessfully，The tool will return a success message "Success"; if it fails, it will generally be the following

• INSTALL_FAILED_ALREADY_EXISTS:  Means that you need to use the-r parameter to reinstall.

• INSTALL_FAILED_SIGNATURE_ERROR:  Means that application signature is inconsistent, and it may be due to the different version of the signature and debug version. If  you confirm the APK file signature is normal, you can use the adb  uninstall command to uninstall the old application, and then install.
  

• INSTALL_FAILED_INSUFFICIENT_STORAGE: Means that not enough storage space  and need to check equipment storage.

Uninstall apk:  adb uninstall

• usage：

adb uninstall apk_name

• example：

adb uninstall com.android.chrome

The name of the application package can be listed with the following command:

adb shell pm list packages -f

The result is:

...
package:/system/app/Bluetooth.apk=com.android.bluetooth
...

The former is the apk file, the latter is the corresponding package name.
