Some useful Android adb commands to share

Here are 1 of the ADB commands I found useful. You can use either manual or automated build and test procedures.

Check the equipment

adb devices

If multiple devices are connected, use use ES9en-ES10en DEVICE_ID to connect to the target device

Install the application

Install 1 apk package using the install command. If the application is already installed on the device, re-install and retain the original application data using -ES19en

adb install -r APK_FILE
#example

adb install -r com.feiliu.wjbd

Uninstall 1 application

adb uninstall APK_FILE
#example

adb uninstall com.feiliu.wjbd

Launch 1 page

adb shell am start PACKAGE_NAME/ACTIVITY_IN_PACKAGE

adb shell am start PACKAGE_NAME/FULLY_QUALIFIED_ACTIVITY
# example

adb shell am start -n com.feiliu.wjbd/.MainActivity

adb shell am start -n com.feiliu.wjbd/com.feiliu.wjbd.MainActivity

Enter the shell interface of the device

adb shell

screenshots

Sergei Shvetsov came up with a nice way to get a screenshot and use shell screencap to output to the local directory via perl. Check out his blog for more details

adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png

XieBing

This command sends an unscreen-release event to the lock screen device

adb shell input keyevent 82

The log

The command line shows Log

adb logcat

Filtered by tagname

adb logcat -s TAG_NAME

adb logcat -s TAG_NAME_1 TAG_NAME_2
#example

adb logcat -s TEST

adb logcat -s TEST MYAPP

Preferred filtering

Displays logs with 1 specific priority warning and above.

adb logcat "*:PRIORITY"
# example

adb logcat "*:W"

Priority:

V - Rules (Minimum priority)
D - debugging
I information -
W - warning
E error -
Deadly F -
S - Silent (highest priority, no information will be printed)

Use grep filtering

This is similar to using pipe command 1 on Linux and requires system support

adb install -r APK_FILE
#example

adb install -r com.feiliu.wjbd

0
Clear log block

Use to clean up old logs

adb logcat -c
