Problem

When trying to use the Android Development Bridge command line tool (adb tool) to list or connect to Android devices from a cluster, you receive an error. 

Error - “FileNotFoundError: [Errno 2] No such file or directory: 'adb'” 

You notice the adb tool works in your local system.

Cause

The adb tool is not installed in the correct system path, causing commands to go unrecognized on the cluster. 

The adb tool comes pre-packaged with Android Studio and Android Platform Tools Bundle, which is why it works in your local system.

Solution

Use the following example init script to install the adb tool in the cluster and set in the correct system path. Because the Databricks Runtime images are Ubuntu-based, the init script uses the Linux download for the adb tool. 

#!/bin/bash
# Download the latest platform-tools for Linux
wget -qO /tmp/platform-tools.zip https://dl.google.com/android/repository/platform-tools-latest-linux.zip
# Unzip the downloaded file to a temporary directory
unzip -q /tmp/platform-tools.zip -d /tmp/
sudo cp /tmp/platform-tools/adb /usr/local/bin/adb
# Clean up temporary files and directories
rm -rf /tmp/platform-tools.zip /tmp/platform-tools
# Optional: Verify the installation by printing adb version
adb version
