Linux & shell adb commands

// Connect device with android studio using usb mode 

Connect your phone to your desktop with usb. 
make sure your desktop have the adb utility and a suitable driver for your phone is installed.

adb start-server ; adb devices
 ##make sure device is connected.

adb shell pm list packages|grep -i "keyword" 
##get the package full name, eg,my phone will get "package:com.sonyericsson.music" by running in powershell>>
adb shell pm list packages|grep -i music

define the package's path "package:/data/app/com.sonyericsson.music-2/base.apk" by shell>>
adb shell pm path com.sonyericsson.music

find the base.apk file in your working dir after running in shell>>
adb pull /data/app/com.netease.cloudmusic-1/base.apk.

As the other guys say the apk file is actually a zip file, the extracting procedure seems easier.
