get APK of installed app with adb command

Question

I try to get the APK file of installed app on my Android phone, I followed this answer which says no need for root access.

I know Facebook app package name is com.facebook.katana, I see it with command adb shell pm list package.

Then, I tried in command line:

adb shell pm path com.facebook.katana

It returns:

package:/data/app/com.facebook.katana-2/base.apk

Then, I pull the apk file to my computer by:

adb pull /data/app/com.facebook.katana-2/base.apk

But output is:

adb: error: remote object '/data/app/com.facebook.katana-2/base.apk' does not exist

Why I can not get the APK but that answer says it works?

Answer 1

Pull the APK file from the Android device to the development box by setting destination path.

adb pull /data/app/com.facebook.katana-2/base.apk path/to/desired/destination

or use,

adb shell cat /data/app/com.facebook.katana-2/base.apk > app.apk
