You might have encountered the error Command ADB not found while working with Android applications on Ubuntu. This tutorial provides the steps to resolve this error. We can fix this error by adding the ADB to the system path by updating either the .bashrc file or /etc/profile file.
Notes: This tutorial assumes that you have already installed JDK and Android Platform Tools on your Ubuntu system. It also assumes that you know the path where Platform Tools and SDK Tools are installed.

The directory structure should be similar as shown below where android-sdk is the ANDROID_HOME directory.
android-sdk |----platform-tools |----cmdline-tools |----|----tools
Update /etc/profile File
You might be required to update your /etc/profile file to configure the JAVA_HOME path as shown below. Your Java path might be different based on your Java installation.
# Update profile sudo nano /etc/profile
# Add at the end # Java 8 #JAVA_HOME=/usr/java/oracle/jdk1.8.0_261 # OpenJDK 15 #JAVA_HOME=/usr/java/openjdk/jdk-15 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin export JAVA_HOME export PATH
Now press Ctrl + O and press Enter to write our change. Press Ctrl + X to exit the nano editor.
Update .bashrc File
Update .bashrc file of the user account as shown below. Update the path to your ANDROID_HOME. I have installed Android SDK Tools and Android Platform Tools at /data/tools/android-sdk.
# Update Bash sudo nano ~/.bashrc
# Android - SDK Tools & Platform Tools export ANDROID_HOME=/data/tools/android-sdk export PATH=/data/tools/android-sdk/platform-tools:/data/tools/android-sdk/cmdline-tools/tools:/data/tools/android-sdk/cmdline-tools/tools/bin:${PATH}
# Save .bashrc
# Reload Bash source ~/.bashrc
Notes: Replace the android sdk path based on your installation directory. In my case, I have installed Android SDK Tools and Android Platform Tools at /data/tools/android-sdk.
Now we will verify the adb and sdkmanager commands as shown below.
# Verify ADB adb --version
# Output Android Debug Bridge version 1.0.41 Version 30.0.4-6686687 Installed as /data/tools/android-sdk/platform-tools/adb
# Verify sdkmanager sdkmanager --version
# Output 4.0.1
Notes: You might be required to close and re-open your terminal to verify the installation of Android Platform Tools and Android SDK Tools.
