# Android 4.3+ changes app's internal directory permissions and you can not just pull your 
# databases to your computer, so I did this as a workaround to extract my databases.
# I only use it for debug, use it under your responsability.

package=$1
db_name=$2
path="/data/data/$package/"

rm $db_name
adb shell "su -c 'cd $path; chmod -R 777 databases; exit'; exit"
adb pull $path/databases/$db_name
open $db_name

Possible way around root, if the app does not have debuggable=false, is to pipe the db file contents...

package=$1
db_name=$2

adb shell "run-as $package cat databases/$db_name > /sdcard/$db_name"
adb pull /sdcard/$db_name
open $db_name
