Restarting Your Android Device from the Linux Shell

Restarting Your Android Device from the Linux Shell

21 May 2024 Stephan Petzl Leave a comment Tech-Help

When working with an Android device in conjunction with a Linux machine, it’s not uncommon to encounter scenarios where the Android interface may hang or become unresponsive. If you’re running scripts that interact with the Android environment through a Linux shell, and you find the need to restart the Android interface without affecting the Linux machine, this guide is for you.

Using ADB to Restart Android

The Android Debug Bridge (ADB) is a versatile command-line tool that allows you to communicate with a device. The ADB command for restarting an Android device is straightforward:

adb reboot

This command will initiate a reboot of the Android OS on the device. It’s important to note that this should not affect the underlying Linux system on which the Android environment is running.

Running Shell Scripts on Android via ADB

If you need to execute a complete shell script on the Android device, you can do so using ADB as follows:

adb shell <command>

Replace <command> with the appropriate shell script or command you wish to run on the Android device. For comprehensive information on ADB commands, you can refer to the official documentation.

Targeting a Specific Device

If you have multiple devices connected and need to target a specific one, you can use the following syntax:

adb -s <device_id> reboot

Here, <device_id> is the unique identifier for the device you wish to reboot. You can obtain this identifier by running:

adb devices

This command will list all connected devices along with their IDs.

Alternative Method: Broadcasting a BOOT_COMPLETED Intent

Another method to simulate a reboot is by sending a BOOT_COMPLETED broadcast:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

This method triggers the system to act as if the device has just finished booting. However, it’s important to note that this does not perform a full reboot of the system.
