I'm trying to delete some files from DDMS data/data/package_name/files/filename How can i done this?
adb shell rm /yourpath/to/yourfilename
Use the File Explorer of the Eclipse DDMS plugin or the adb shell command from your android platform tools to browse and delete the file system on your device.
You can use ADB to get into the device/emulator shell and then execute normal linux-commands.
In your case, you would use rm to remove something (if you want to remove a folder use the -r parameter).
From the Android Docs:
Internal Storage
You can save files directly on the device's internal storage. By
default, files saved to the internal storage are private to your
application and other applications cannot access them (nor can the
user). When the user uninstalls your application, these files are
removed.
This might help you. You can also check if you can "delete application data" in Androids Application Manager.

I created my first Android App with SQLite and tested it on my phone.
Now I installed an SQLiteManager on the phone and I would like to open the SQLitedatabse file.
The location is /data/user/0/com.<appname>/database/database.db
But this folder does not exist. How can I find and access the database file?
And I am also not able to find the apk of my App. In Android/data/ I can see all other installed apps, but not my own app.
How can I find yout where it is located?
The acutal path is /data/data/package.name/database.
If your app is in debug mode, most newer devices allow accessing this folder via Android Studio (or adb run-as). On the emulator this folder is public.
Just run the command in terminal
adb pull /data/data/com.example.myapplication/databases/your_db.db
No need to root your device.
I used this way on Mac with Terminal:
sudo adb -d shell "run-as com.YOUR_COMPANY.YOUR_APP_NAME cat databases/YOUR_DATABASE_NAME.db" > NEW_NAME_FOR_DATABASE.sqlite
Sometimes you need first to give that file a permission 666, so you can copy it to your computer.
chmod 666 YOUR_DATABASE_NAME.db
Your device must be Rootable for you to be able to see the .DB file
for the second question, try to search for your package name first. Maybe it's like xxx.xxx.Christina.xxx.AppName ?
I am developing an application using ionic framework.
The app creates files (*.json) and stores them in /data/user/0/ when i verify whether they exist or not, the result was true which means the files exist in the mentioned directory and I can access and modify their content without problem, but when I check the directory with a file manager or from the computer, no result, the directory is empty.
Could someone tell me what should I do?
use adb to copy the file. Even if it's in root dir, u should have access to it via adb.
Do adb pull data/user/0/filename.json path_on_ur_comp.json.
this will copy the file to the directory you define in the 2nd parameter.
// EDIT:
adb is part of the Android SDK, stands for Android Debug Bridge.
You can use this for MANY MANY different reason but of course, the "main" reason is to debug Android devices. You can use it to transfer files in your case.
In Windows, it's located here:
C:\Users\USERNAME\AppData\Local\Android\sdk\platform-tools\adb
In Mac, it's lcoated here:
/Users/USERNAME/Library/Android/sdk/platform-tools/adb
Depending on which OS you use, open that either with Terminal (Mac) or Command Prompt (Windows).
Once you do that, run the following command:
For Mac:
adb pull data/user/0/filename.json /Users/USERNAME/Desktop/somefile.json
For Windows:
adb pull data/user/0/filename.json c:\Users\USERNAME\Desktop\somefile.json
This will copy the file and put it on your desktop
I'm debugging my android app in Android Studio using a real android device and. I see that the Sqlite db path is
/data/data/com.my_app/databases/data1.db
I want to remove it. By that path doesn't exist when try to find it by a file manager. And, of course, this isn't working:
adb -e shell rm /data/data/com.my_app/databases/data1.db
adb server is out of date. killing...
* daemon started successfully *
error: device not found
So how can I remove it and why isn't it visible in my smartphone?
why isn't it visible in my smartphone?
Because it is on internal storage, which you do not have access to, except on emulators and rooted devices.
And, of course, this isn't working:
That is some separate problem with adb running on your machine.
So how can I remove it
If you want to completely clear your app's data (databases, SharedPreferences, and other files) on internal storage, use the Settings (e.g., Settings > Apps > (your app) > Clear Data on Android 4.x/5.x).
If you specifically want to get rid of this file on an emulator, the command you tried should be fine. I suggest restarting the emulator.
If you specifically want to get rid of this file on production hardware, you will need to use run-as:
adb shell run-as com.my_app rm /data/data/com.my_app/databases/data1.db
You can't reach that directory if your device isn't root . For change or modify system files you must have root access .
i am trying to see SQLite database in anyway possible (I have a rooted device). I tried File explorer in eclipse but i cannot see anything under data folder. Can anybody please help me with this
I tried to search everywhere but couldnt find a clear solution.
I also tried adb shell but i cannot see list of things inside data folder using "ls" command.
error
Opendir failed. Permission denied
I am guessing this has something to do with rights but how can i fix it
Please help
You need root premission to explore DATA directory...
From phone
I use terminal emulator to do the job..... Simply open terminal then type in su after that it will ask for premision. then you need to type cd data/data/WhereEverYouNeedToGo/databases and "WhereEverYouNeedToGo" should be package name. After that you could do whatever you want with your database.
from PC
open terminal or cmd goto your adb directory then run adb shell then su and then
cd data/data/WhereEverYouNeedToGo/databases
Hope it helped.
Run adb in root mode using "adb root"
adb shell
su
ls /data/
Try this
You have been given a number of answers for how to leverage the root capability, however as android is designed without the assumption of root there are other methods as well which you can use while developing apps.
1) Include functionality on an expert menu to copy the database to the sdcard; there is no file copy method in android java (and in most stock cases no 'cp' shell command), but you can find numerous answers here with a copy routine.
2) Make your apk debuggable and use the run-as command to obtain a shell running as the application userid and starting in the app's data directory. You can then copy the database to the sdcard if the app has that permission.
3) Have your app set the permissions on the database file during development to world readable. Although you cannot browse the directory tree to down to it, you can then adb pull the database file by giving it's full path name.
You need to have either routed device or your device should be a "Android Dev Phone" to explore that directory. Trying checking the same using emulator, you will be able to see the data folder contents.
I'm new to Android development. I want to access "data/app folder in Android eclipse emulator to take backup of apk file that store in that directory but unfortunately I am unable to get access to that directory.
I have tried FACTORY_TEST to get root access permission but still no success.
you can do it by using adb command : e.g
E:\android-sdk-windows\platform-tools>adb pull /data/app/filename.apk e:\
If you don't have root access on the machine it's impossible. The phone need to be rooted in order to allow your app to do this kind of things.
First your phone should be rooted, you can use https://www.kingoapp.com/ for that.
Next, you should modify the permission of your app access, to do so you have to :
Locate your adb.exe folder (you can find it in your sdk folders)
Right click
open cmd here
Type:
adb shell
su
chmod 777 /data /data/data /data/data/yourapp
Good luck
