How can one pull the (private) data of one's own Android app?

Attempting to pull a single file using

fails with

failed          


        

Answer 1

I had the same problem but solved it running following:

$ adb shell
$ run-as {app-package-name}
$ cd /data/data/{app-package-name}
$ chmod 777 {file}
$ cp {file} /mnt/sdcard/

After this you can run

$ adb pull /mnt/sdcard/{file}
