How to access data/data folder in Android device?

I am developing an app and I know my database *.db will appear in data/data/com.****.***

I can access this file from AVD in Eclipse with help of sqlite manager

But I can't access this file in my Android phone.
I googled it and it says I need to root my phone to do it, but I don't want to do that.

How can I access my data/data/..... directory in my Android phone "without rooting it"?

Can I change user permissions for the directory data/data..... without rooting it?

Accessing the files directly on your phone is difficult, but you may be able to copy them to your computer where you can do anything you want with it. Without rooting you have 2 options:

1. If the application is debuggable you can use the run-as command in adb shell

    adb shell
    run-as com.your.packagename 
    cp /data/data/com.your.packagename/
   

2. Alternatively you can use Android's backup function.

    adb backup -noapk com.your.packagename
   

   You will now be prompted to 'unlock your device and confirm the backup operation'. It's best NOT to provide a password, otherwise it becomes more difficult to read the data. Just click on 'backup my data'. The resulting 'backup.ab' file on your computer contains all application data in android backup format. Basically it's a compressed tar file. This page explains how you can use OpenSSL's zlib command to uncompress it. You can use the adb restore backup.db command to restore the backup.

If you are using Android Studio 3.0 or later version then follow these steps.

1. Click View > Tool Windows > Device File Explorer.
2. Expand /data/data/[package-name] nodes.

You can only expand packages which runs in debug mode on non-rooted device.

You could also try fetching the db using root explorer app. And if that does not work then you can try this:

1. Open cmd
2. Change your directory and go into 'Platform tools'
3. Type 'adb shell'
4. su
5. Press 'Allow' on device
6. chmod 777 /data /data/data /data/data/com.application.package /data/data/com.application.package/*
7. Open DDMS view in Eclipse and from there open 'FileExplorer' to get your desired file

After this you should be able to browse the files on the rooted device.

To do any of the above (i.e. access protected folders from within your phone itself), you still need root. (That includes changing mount-permissions on the /data folder and accessing it)

Without root, accessing the /data directly to read except from within your application via code isn't possible. So you could try copying that file to sdcard or somewhere accessible, and then, you should be able to access it normally.

Rooting won't void your warranty if you have a developer device. I'm sorry, there isn't any other way AFAIK.

1. Open your command prompt

2. Change directory to E:\Android\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk\platform-tools

3. Enter below commands

4. adb -d shell

5. run-as com.your.packagename cat databases/database.db > /sdcard/database.db

6. Change directory to cd /sdcard to make sure database.db is there.

7. adb pull /sdcard/database.db or simply you can copy database.db from device .

The easiest way (just one simple step) to pull a file from your debuggable application folder (let's say /data/data/package.name/databases/file) on an unrooted Android 5.0+ device is by using this command:

adb exec-out run-as package.name cat databases/file > file

Use File Explorer in eclipse. Select Windows => Show View => Other ... => File Explorer.

An another way is pull the file via adb:

adb pull /system/data/data/<yourpackagename>/databases/<databasename> /sdcard

To backup from Android to Desktop

Open command line cmd and run this: adb backup -f C:\Intel\xxx.ab -noapk your.app.package. Do not enter password and click on Backup my data. Make sure not to save on drive C root. You may be denied. This is why I saved on C:\Intel.

To extract the *.ab file

1. Go here and download: https://sourceforge.net/projects/adbextractor/
2. Extract the downloaded file and navigate to folder where you extracted.
3. run this with your own file names: java -jar abe.jar unpack c:\Intel\xxx.ab c:\Intel\xxx.tar

may be to access this folder you need administrative rights.

so you have two options:-

1. root your device and than try to access this folder
2. use emulator

p.s. : if you are using any of above two options you can access this folder by following these steps

> open DDMS perspective -> your device ->(Select File Explorer from > right window options) select package -> data -> data -> package name > ->files

and from there you can pull up your file

I had also the same problem once. There is no way to access directly the file within android devices except adb shell or rooting device.

Beside here are 02 alternatives:

 public void exportDatabse(String databaseName)

   {
     try {
        File sd = Environment.getExternalStorageDirectory();
        File data = Environment.getDataDirectory();

        if (sd.canWrite()) {
            String currentDBPath = "//data//"+getPackageName()+"//databases//"+databaseName+"";
            String backupDBPath = "backupname.db";
            File currentDB = new File(data, currentDBPath);
            File backupDB = new File(sd, backupDBPath);

            if (currentDB.exists()) {
                FileChannel src = new FileInputStream(currentDB).getChannel();
                FileChannel dst = new FileOutputStream(backupDB).getChannel();
                dst.transferFrom(src, 0, src.size());
                src.close();
                dst.close();
            }
        }
    } catch (Exception e) {

    }
}

2) Try this: https://github.com/sanathp/DatabaseManager_For_Android

On a rooted device, the correct solution is this:

Open cmd
Change your directory and go into 'Platform tools'
Type 'adb shell'
su
Press 'Allow' on device
chmod 777 /data /data/data /data/data/*
Open DDMS view in Eclipse/IntelliJ and from there open 'FileExplorer' to get your desired file

The original solution worked, but the chmod would return unknown directory. Changing the chmod command to /data/data/* gave access to all subfolders in the data directory from DDMS in Intellij. I assume the same solution is true for Eclipse DDMS.

UPDATE So, what I've found is strange. I'm running a Nexus 6 using DDMS in IntelliJ (Android Device Monitor). I have built a little starter app. Said app saves data to a .csv file in data/data/com.example.myapp/files

When I first started to try to access this file on my Nexus 6, I found that I have to root the device.. I could see the data folder, but trying to open it would not work. As mentioned online in other places, the expand + would vanish then reappear shortly thereafter (note, there are solutions on the web that claim to allow access to these folders without rooting, I didn't find them till too late, and I'm not sure if I prefer not to root anyway ((I'd rather be able to do it manually than rely on an app or command prompt to give me my solutions))). I rooted my 6 and tried DDMS again.

At this point, it showed me the data folder and I could expand the folder and see the com. directories, but I could not open any of them. That is when I discovered the above solution. The initial instructions would not work on this part:

chmod 777 /data /data/data /data/data/com.application.pacakage /data/data/com.application.pacakage/*

That is when I tried the solution I posted:

chmod 777 /data /data/data /data/data/*

That solution seemed to work, but only on certain folders. I now could expand my myapp folder, but could not expand the files directory in it.

At this point, I played around for a while then figured why not just try it on the directory I need rather than trying these wildcard entries.

chmod 777 /data /data/data /data/data/com.example.myapp/*

Followed by:

chmod 777 /data /data/data /data/data/com.example.myapp/files

These commands allowed me to expand and view the files in my app's directory to confirm that the .csv was being saved correctly.

Hope this helps someone. I struggled with this for hours!

(to compound on this a tad further, oddly enough, the permissions did not pass to the .csv file that passed to the files directory. my files directory permissions read drwxrwxrwx and my log.csv file permissions read -rw-rw---- .. just fyi)

You can download a sigle file like that:

adb exec-out run-as debuggable.app.package.name cat files/file.mp4 > file.mp4

Before you download you might wan't to have a look at the file structure in your App-Directory. For this do the following steps THelper noticed above:

adb shell
run-as com.your.packagename 
cd files
ls -als .

The Android-Studio way Shahidul mentioned (https://stackoverflow.com/a/44089388/1256697) also work. For those who don't see the DeviceFile Explorer Option in the Menu: Be sure, to open the /android-Directory in Android Studio. E.g. react-native users have this inside of their Project-Folder right on the same Level as the /ios-Directory.

adb backup didn't work for me, so here's what I did (Xiaomi Redmi Note 4X, Android 6.0):

1. Go to Settings > Additional Settings > Backup & reset > Local backups.
   
2. Tap 'Back up' on the bottom of the screen.
   
3. Uncheck 'System' and 'Apps' checkmarks.
   
4. Tap detail disclosure button on the right of the 'Apps' cell to navigate to app selection screen.
   
5. Select the desired app and tap OK.
   
6. After the backup was completed, the actual file need to be located somehow. Mine could be found at /MIUI/backup/AllBackup/FOLDER_NAMED_AFTER_BACKUP_CREATION_DATE.
   
7. Then I followed the steps from this answer by RonTLV to actually convert the backup file (.bak in my case) to tar (duplicating from the original answer):
   "
   a) Go here and download: https://sourceforge.net/projects/adbextractor/<br> b) Extract the downloaded file and navigate to folder where you extracted.
   c) run this with your own file names: java -jar abe.jar unpack c:\Intel\xxx.ab c:\Intel\xxx.tar
   "

One of the simple way is to create your database on SD-Card. Because you cannot get access to your phone's data folder in internal memory, unless you root your phone. So why not simply create your database on SD-Card.

Moreover, if you want, you may write some file copying-code to copy your existing database file (from internal memory) to external memory without requiring any root.

you can copy this db file to somewhere in eclipse explorer (eg:sdcard or PC),and you can use sqlite to access and update this db file .

You can also try copying the file to the SD Card folder, which is a public folder, then you can copy the file to your PC where you can use sqlite to access it.

Here is some code you can use to copy the file from data/data to a public storage folder:

private void copyFile(final Context context) {
    try {
        File sd = Environment.getExternalStorageDirectory();
        File data = Environment.getDataDirectory();

        if (sd.canWrite()) {
            String currentDBPath =
                    context.getDatabasePath(DATABASE_NAME).getAbsolutePath();

            String backupDBPath = "data.db";
            
            File currentDB = new File(currentDBPath);
            File backupDB = new File(sd, backupDBPath);

            if (currentDB.exists()) {
                FileChannel src = new FileInputStream(currentDB).getChannel();
                FileChannel dst = new FileOutputStream(backupDB).getChannel();
                dst.transferFrom(src, 0, src.size());
                src.close();
                dst.close();
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />

SQLlite database is store on user's Phone and it's hidding under path:

/Data/Data/com.companyname.AppName/File/

you have 2 options here:

1. you can root your phone so that you get access to view your hidding db3 file

2. this is not a solution but a work around. Why not just create test page that display your database table in it using 'select' statment.
