Cheat Sheet

Dumping system data

You can dump system data to the screen by the command shell dumpsys. The output shows lots of information, so you might redirect STDOUT to a text file.

% adb shell dumpsys > dump.txt
% less dump.txt
Currently running services:
  SurfaceFlinger
  accessibility
  account
  activity
  ...

The first section tells about Currently running services. If a service name is specified after dumpsys, then the other sections are filtered out.

# Show only "battery"
% adb shell dumpsys battery
Current Battery Service state:
  AC powered: true
  USB powered: false
  Wireless powered: false
  ...

Investigating intent filters

Look up the Activitiy Resolver Table section in the output of the command shell dumpsys package.

% adb shell dumpsys package > package.txt
% less package.txt
...
