The problem could be that we need to specifically give adb root access in the developnent options in the latest CMs.. Here is what i did.

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server * daemon not running. starting it now on port 5037 * * daemon started successfully * root access is disabled by system setting - enable in settings -> development options

after altering the development options...

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root
abc@abc-L655:~$ adb shell
root@android:/ # ls /data/ .... good to go..

There are two things to remember if you want to browse everything on your device    You need to have a phone with root access in order to browse the data folder on an Android phone  That means either you have a developer device  ADP1 or an ION from Google I O  or you ve found a way to  root  your phone some other way  You need to be running ADB in root mode  do this by executing  adb root

I had a lot of trouble with this also  I still don t fully understand the permission and root run  but this worked for me  one of the previous answers partly  to copy database file from  data data  package name  databases my db db   Running shell root  or su in shell for some reason didn t work  nor did copying the db file  I could navigate to the directory though   nor did sqlite3    So  this worked  In DOS command prompt    C  Program Files Android android-sdk platform-tools gt adb shell 1 shell android     run-as de vogella android locationapi maps run-as de vogella android locationapi maps 1 shell android  data data de vogella android locationapi maps   cd  data cd  data shell android  data   cd data cd data shell android  data data   cd de vogella android locationapi maps cd de vogella android locationapi maps shell android  data data de vogella android locationapi maps   cd databases cd databases shell android  data data de vogella android locationapi maps databases   ls ls bus timetable lines db bus timetable lines db-journal shell android  data data de vogella android locationapi maps databases   cat bus  timetable lines db  gt   sdcard db copy db  bus timetable lines db  gt   sdcard db copy db                                    lt  shell android  data data de vogella android locationapi maps databases  exit     exit shell android     exit exit  C  Program Files Android android-sdk platform-tools gt    Now go to SDCARD directory and get your file db copy db   Even that was hidden  but I managed to email it  Back in Windows  I was able to open db file with SQLite Database Browser

I had a similar problem when trying to operate on a rooted Samsung Galaxy S  Issuing a command from the computer shell   gt  adb root   fails with a message  cannot run as root in production builds   Here is a simple method that allows to become root   Instead of the previous  issue the following two commands one after the other   gt  adb shell   su   After the first command  if the prompt has changed from     to     as shown above  it means that you have entered the adb shell environment  If subsequently the prompt has changed to     after issuing the second command  that means that you are now root  Now  as root  you can do anything you want with your device   To switch back to  safe  shell  issue    exit   You will see that the prompt     reappears which means you are in the adb shell as a user and not as root

Starting from API level 8  Android 2 2   for the debuggable application  the one built by Android Studio all the times unless the release build was requested   you can use the shell run-as command to run a command or executable as a specific user application or just switch to the UID of your application so you can access its data directory   List directory content of yourapp   run-as com yourapp ls -l  data data com yourapp   Switch to UID of com yourapp and run all further commands using that uid  until you call exit    run-as com yourapp cd  data data com yourapp ls -l exit    nbsp  Note 1  there is a known issue with some HTC Desire phones  Because of a non-standard owner permissions of the  data data directory  run-as command fails to run on those phones   Note 2  As pointed in the comments by  Avio   run-as has issues also with Samsung Galaxy S phones running Cyanogenmod at any version  from 7 to 10 1  because on this platform  data data is a symlink to  datadata  One way to solve the issue is to replace the symlink with the actual directory  unfortunately this usually requires root access

if you know the application package you can cd directly to that folder     eg  cd data data com yourapp  this will drop you into a directory that is read writable so you can change files as needed   Since the folder is the same on the emulator  you can use that to get the folder path
