VAR-SOM-MX6 - Android Nougat - ADB and fastboot

What is adb?

The Android Debug Bridge (adb) is a development tool that facilitates communication between an Android device and a personal computer.
This communication is most often done over a USB cable, but Wi-Fi connections are also supported.

adb is like a “Swiss-army knife” of Android development. It provides numerous functions that are described in detail by the command adb --help.
Some of the more commonly used commands are listed in the “popular adb commands” section below.

Installing adb and fastboot

Google hosts zips including only adb and fastboot.
You can set these up for use with the instructions below.

On Windows

Download the Windows zip from Google depending upon your OS.

https://developer.android.com/studio/releases/platform-tools

On Windows 7/8

From the desktop, right-click My Computer and select Properties
In the System Properties window, click on the Advanced tab
In the Advanced section, click the Environment Variables button
In the Environment Variables window, highlight the Path variable in the Systems Variable section and click the Edit button

Append ;%USERPROFILE%\adb-fastboot\platform-tools to the end of the existing Path definition (the semi-colon separates each path entry)

On Windows 10

Open the Start menu and type “advanced system settings”
Select “View advanced system settings”
Click on the Advanced tab
Open the “Environment Variables” window
Select the Path variable under “System Variables” and click the “Edit” button
Click the “Edit Text” button

Append ;%USERPROFILE%\adb-fastboot\platform-tools to the end of the existing Path definition (the semi-colon separates each path entry).
Install the universal adb driver, and reboot.

On macOS

Download the macOS zip from Google
Extract it somewhere - for example, ~/adb-fastboot
Add the following to ~/.bash_profile:

if [ -d "$HOME/adb-fastboot/platform-tools" ] ; then
	export PATH="$HOME/adb-fastboot/platform-tools:$PATH"
fi

Log out and back in

On Linux

Download the Linux zip from Google
Extract it somewhere - for example, ~/adb-fastboot.
Add the following to ~/.profile:

if [ -d "$HOME/adb-fastboot/platform-tools" ] ; then
	export PATH="$HOME/adb-fastboot/platform-tools:$PATH"
fi

Log out and back in

Udev Rules for OTG / USB Device

You may also need to set up udev rules: see this repository for more info.
Refer to: https://github.com/snowdream/51-android

$ sudo curl --create-dirs -L -o /etc/udev/rules.d/51-android.rules -O -L https://raw.githubusercontent.com/snowdream/51-android/master/51-android.rules
$ sudo chmod a+r /etc/udev/rules.d/51-android.rules
$ sudo service udev restart

Setting up adb
To use adb with your device, you’ll need to enable developer options and USB debugging:

Note: By default, it is enabled in our Android OS for Eng build.

Open Settings, and select “About”. Tap on “Build number” seven times. Go back, and select “Developer options”. Scroll down, and check the “Android debugging” entry under “Debugging”. Plug your device into your computer. On the computer, open up a terminal/command prompt and type adb devices. A dialog should show on your device, asking you to allow usb debugging. Check “always allow”, and choose “OK”. Congratulations! adb is now ready to use with your device.

Setting up fastboot Using fastboot (if your device supports it) should simply involve rebooting to fastboot mode. While in fastboot mode, you can type fastboot devices to verify that your device is being detected.

Popular adb commands

adb shell - launches a shell on the device
adb push <local> <remote> - pushes the file <local> to <remote>
adb pull <remote> [<local>] - pulls the file <remote> to <local>. If <local> isn’t specified, it will pull to the current folder.
adb logcat - allows you to view the device log in real time. You can use adb logcat -b radio to view radio logs, and adb logcat -C to view logs in color
adb install <file> - installs the given .apk file to your device
