ADB 101

See full documentation here: https://developer.android.com/studio/command-line/adb

Basics

Check if you have any devices connected:

adb devices

If more than one device is connected, you need to pass device serial to every adb command:

adb -s 12345678 install com.package

Install/Uninstall

Install an APK:

adb install /path/to/apk/com.pocketgeek.android-3.4.5-12345.apk

Uninstall a package:

adb uninstall com.package.name

Working with logs

Print all logs in terminal:

adb logcat

Filter logs by priority level (D for 'debug', W for 'warning', E for 'error'):

adb logcat *:w

Note: when you specify the level in filter, it will print that level and higher. E.g., 'w' will include 'warning' and 'error'. Priority levels here for reference.

Record logs to a file:

adb logcat > file.log

Print logs to terminal and record to file:

adb logcat | tee file.log

Filter for crashes:

• Using logcat buffer: crash:

adb logcat -b crash

• Using native ADB tags:

adb logcat AndroidRuntime:E *:S

• You can also grep for 'FATAL EXCEPTION' + x lines after:

adb logcat | grep FATAL -A 30

PM (package manager)

List all installed packages:

adb shell pm list packages

Only list 3rd party apps (exculde system apps):

adb shell pm list packages -3

Filter by specific package name (using grep and pattern):

adb shell pm list packages | grep pocketgeek

Clear app data:

adb shell pm clear com.package.name

WM (window manager)

Change your screen density (for simulating small/large screen device)

To see current and/or default DPI:

adb shell wm density

Change the DPI to a desired value:

adb shell wm density 200

Reset to deafault:

adb shell wm density reset

You can also change the screen size/resolution: replace 'density' with 'size' in the commands above.

Mocking battery states

To see current battery stats:

adb shell dumpsys battery

To mock your battery level:

adb shell dumpsys set level <number b/w 1-100>

To mock your battery status (charging ac, charging usb, charging wireless, not charging):

adb shell dumpsys set status 1/2/3/4

See all battery status constants here

Alternative way to set status 'unplugged':

adb shell dumpsys battery unplug

Reset mocked battery state:

adb shell battery reset

Misc

Launch an app:

adb shell monkey -p com.package name 1
