packages - Does Android keep the .apk files? if so where?

Question

After android installs an application from the Marketplace, does it keep the .apk file?

Is there a standard location where Android would keep such files?

Answer 1

You can use package manager (pm) over adb shell to list packages:

adb shell pm list packages | sort

and to display where the .apk file is:

adb shell pm path com.king.candycrushsaga
package:/data/app/com.king.candycrushsaga-1/base.apk

And adb pull to download the apk.

adb pull data/app/com.king.candycrushsaga-1/base.apk
