android adb shell command to play sound from the command line solutions

The Android operating system is one of the most popular mobile operating systems in the world. Many developers and power users take advantage of the Android Debug Bridge (ADB) tool to control their devices from their computer. One use case of this tool is to play sounds on an Android device directly from the command line. In this article, we will explore the various methods and solutions available to play sounds on an Android device using the ADB shell command.

What is ADB?

ADB is a command-line tool that allows developers and power users to interact with Android devices from their computer. It allows users to install and uninstall apps, transfer files, and even control their devices remotely. ADB is installed on every Android device by default, and it can be accessed through the command prompt on Windows or the Terminal app on macOS and Linux.

Why Play Sound from ADB?

Playing sound from ADB can be useful for a variety of reasons. For example, you may want to play a notification sound when a particular command finishes running, or you may want to test how an app reacts to certain audio files.

There are several ways to play sound from ADB shell, and we will cover them in the following sections.

Method 1: Play Sound from SD Card

The first method to play sound from ADB is to copy the sound file to the SD card and play it using the media player app. Here are the steps to follow:

  1. Copy the sound file to the SD card

Connect your Android device to your computer using a USB cable and navigate to the SD card using ADB shell. To do this, type the following command in the command prompt or Terminal:

$ adb shell

$ cd /sdcard

Copy the sound file to the SD card using the following command:

$ adb push /path/to/sound/file .

Replace "/path/to/sound/file" with the actual file path on your computer.

  1. Play the sound file using the media player app

Next, play the sound file using the media player app. This can be done using the following command:

$ adb shell am start -a android.intent.action.VIEW -d file:///sdcard/soundfile.mp3 -t audio/mp3

Replace "soundfile.mp3" with the actual filename of the sound file you copied to the SD card.

Method 2: Play Sound from Raw Resources

Another method to play sound from ADB is to copy the sound file to the "raw" folder of the app you want to play it in and play it using the MediaPlayer class. Here are the steps to follow:

  1. Copy the sound file to the "raw" folder

First, create a new folder called "raw" in the "res" folder of the app you want to play the sound in. Next, copy the sound file to the "raw" folder.

To do this, connect your Android device to your computer using a USB cable and navigate to the app folder using ADB shell. To do this, type the following commands in the command prompt or Terminal:

$ adb shell

$ cd /data/app/com.example.app-*/base.apk

Replace "com.example.app" with the package name of the app you want to play the sound in.

Next, copy the sound file to the "raw" folder using the following command:

$ adb push /path/to/sound/file ./res/raw/

Replace "/path/to/sound/file" with the actual file path on your computer.

  1. Play the sound file using MediaPlayer

Next, play the sound file using the MediaPlayer class. This can be done using the following ADB shell command:

$ adb shell am start -n com.example.app/.MainActivity

$ adb shell input keyevent KEYCODE_MENU

$ adb shell input tap x y

Replace "com.example.app" with the package name of the app and "MainActivity" with the name of the activity that contains the MediaPlayer. Replace "x" and "y" with the pixel coordinates of the "Play" button on the screen.

Method 3: Play Sound using ADB Shell Script

Finally, you can create an ADB shell script to play sound from the command line. This method is more flexible and allows you to play multiple sounds with one command. Here are the steps to follow:

  1. Create a shell script on your computer

First, create a new file on your computer called "play_sound.sh". Add the following content to the file:

#!/bin/bash

echo "Playing sound file…"

adb shell am start -a android.intent.action.VIEW -d file:///sdcard/soundfile.mp3 -t audio/mp3

Replace "soundfile.mp3" with the actual filename of the sound file you want to play.

  1. Make the script executable

Next, make the script executable using the following command:

$ chmod +x play_sound.sh

  1. Run the script

Finally, run the script using the following command:

$ ./play_sound.sh
