Here are some of the commands I find useful for Android's
adb. They can be used manually or to automate your build or testing process.
View connected device(s)
Use this to view all connected devices and list their IDs.
If multiple devices are attached, use
adb -s DEVICE_ID to target a specific device.
Install an application
install command to install an apk, the optional
-r argument reinstalls and keeps any data if the application is already installed on the device.
adb install -r APK_FILE # example adb install -r ~/application.apk
Uninstall an application
adb uninstall PACKAGE_NAME # example adb uninstall com.growingwiththeweb.example
Start an activity
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.growingwiththeweb.example/.MainActivity adb shell am start -n com.growingwiththeweb.example/com.growingwiththeweb.example.MainActivity
Entering the device’s shell
Take a screenshot
adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png
This command sends the power button event to turn the device on or off.
adb shell input keyevent 26
This command sends the event that unlocks the lockscreen on the device. It can be combine with the power button command above to turn on and unlock the device.
adb shell input keyevent 82
Print all installed packages
adb shell pm list packages -f
Clear application data
adb shell pm clear PACKAGE_NAME # example adb shell pm clear com.growingwiththeweb.example
To show the log stream on your command line.
Filter 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
Filter by priority
To show logs of a specific priority warning and above.
adb logcat "*:PRIORITY" # example adb logcat "*:W"
Here are the priority levels:
V- Verbose (lowest priority)
S- Silent (highest priority, on which nothing is ever printed)
Filter by tagname and priority
adb logcat -s TAG_NAME:PRIORITY adb logcat -s TAG_NAME_1:PRIORITY TAG_NAME_2:PRIORITY #example adb logcat -s TEST: W
Alternatively the output of
logcat can be piped to
grep on a system that supports it.
adb logcat | grep "SEARCH_TERM" adb logcat | grep "SEARCH_TERM_1\|SEARCH_TERM_2" #example adb logcat | grep "Exception" adb logcat | grep "Exception\|Error"
Use this to clear the buffer to remove any old log data.
adb logcat -c

adb reference site.
