Listing All Processes in Android O with ADB Shell

Listing All Processes in Android O with ADB Shell

21 May 2024 Stephan Petzl Leave a comment Tech-Help

When working with Android O (also known as Android 8.0), developers might encounter a change in the behavior of the ADB shell’s process status (ps) command. Unlike previous versions of Android, running adb shell ps in Android O may not display all running processes. This can be puzzling for those accustomed to the comprehensive output provided in earlier releases.

Understanding the Change

In Android O, Google has updated the ps binary, which has resulted in a modification of the default output of the ps command. This change aims to streamline the information displayed, but it also necessitates the use of additional flags to access the full list of processes.

Listing All Processes

To list all processes in Android O, you’ll need to use the -A flag with the ps command. The correct command is:

adb shell ps -A

This command will provide a complete list of all processes running on the device, similar to what developers expect from previous versions of Android.

Additional Options for Customization

Android O’s ps command now includes several new options, offering more control over the output. You can view these options by running:

adb shell ps --help

Some of the key options include:

  • -A or -e for all processes
  • -T to show threads
  • -o to customize the fields displayed (e.g., PID, TTY, TIME, CMD)
  • -f for a full listing
  • -l for a long listing
  • -n to show numeric USER and GROUP
  • -w for wide output (prevents field truncation)

These options empower developers to tailor the ps output to their specific needs, enhancing their ability to monitor and debug processes on Android devices.
