I am testing an Android application.
I would like to keep an eye on the content of
while the app is running.
But my app does not work correctly if the sd card is mounted as disk drive on PC (accesses pictures and videos).
So I thought I could use adb shell. But it doesn’t let me access that same folder:
ls /sdcard/Android/data/com.myapplication /sdcard/Android/data/com.myapplication: Permission denied
Looking on Stack Overflow, I found this way to see application data via adb shell:
and doing so I find myself in the folder
What I’m confused about is that the data I see here are different from the data I see browsing the sdcard content via PC.
$ ls ls files databases shared_prefs lib
I see under files something that was also under the sdcard Android/data/com.myapplication folder, but not what I was looking for. Besides, all other folders are different.
Is there a correlation between this
folder accessible via adb and the
folder accessible via PC?
Is there a way to see in adb shell the files present in the latter?
As a general rule, files that are on the
Internal storage and stored by your app (by default not
WORLD_READABLE) will only be available for your application to read. When you try to
pull these files using
adb pull you will get permission denied on a NOT rooted device. There is a way to go around this, I will explain later. Files in
External storage on the other hand, are available to the User and to all other apps to read. so it depends on what you are after.
Now in order to read files in your internal storage (
/data/data/com.app.name) you cannot read these files directly, but what you can do is move them to the external storage and then read them from there like this.
adb shell "run-as com.yourappName cat /data/data/com.yourappName/files/myfile.txt > /sdcard/Downloads/myfile.txt"
Then you can pull the file from the external storage with no permission issues.
adb pull /sdcard/Downloads/myfile.txt
If you are unsure about which file or you want to browse all the files, then user the shell to browse all your app files.
adb shell run-as yourappPackageName cd /data/data/youappPackageName ls -all
I have been able to get the Sqlite DB the App is using with this Adb command:
adb exec-out run-as xxx.xxx.xxx.xxx cat "/data/data/xxx.xxx.xxx.xxx/databases/databasefile.db" > %userprofile%\Desktop\databasefile.db
Where xxx.xxx.xxx.xxx is the bundleId of your Android App, and databasefile.db is the name of the Sqlite DB
So I imagine you can get any existing file of the App, knowing where is it, and using the
adb exec-out run-as xxx.xxx.xxx.xxx command
You can access it via utility which was posted earlier in a blog.
Its a java utility through which you can get the all folders in your application’s data folder by just giving the package name of your application.
Just app needs to be debuggable.
