When developing for Android I prefer just working with a real device plugged in most of the time since the Android emulators are such total garbage. The one pain point is when I want to access files and sqlite databases though. I believe with the adb shell it is possible to pull the database across, but this isn't a very convenient process.
I'm wondering if there are any tools on the market that allow you to see the database in real time, even if it requires rooting a device I'm open to it.
I am afraid that there are no tools that will let you see the db real time. You will need to get the db from the device and the see it on your system. You will have to root the phone and get SuperUser permission to access app databases. The database will (after getting root) then be available in the /data/data/com.your.application/databases folder.
Hi You don't have any tools to see the database in real times. But its achievable in rooted device. If your device is rooted just install root explorer app in it. and then browse for your package name in data/data/ location. There you will find out all the internal memory files including database files. hope this helps you.

I'm working on an Android Forensic application to retrieve deleted text messages, email and call history from any Android device. I managed to extract several deleted records from sqlite database using my C++ app however to get the sqlite dbs I should be connected to a rooted Android device which is practically not possible as the people who will be using this app doesn't have much technical expertise and they won't be able to root the device.
To work around this problem, I'm thinking about carving sqlites from file system images and I'm very confident of doing the same once I get access to the image files. So I tried dd and nanddump but it seems like they both need write access to the partitions to dump the images.
So I'd like to know whether there is a way to dump the userdata partition without su / root permission on the device?
I opened a SQLite database in my project. To see if the db was actually created I went to Data/Data to find the package name... not there. While testing I would like the ability to delet the file.
So I added data to the db, then read it out. This works fine, but still no file at either /Data/Data, or at /Android/Data/Data. Is the file hidden? Other dowloaded aps have data at /Data/Data/package/... but not the one I wrote. It does exist - I can read and write to/from it, but cannot find it.
//data/data/Your-Application-Package-Name/databases/your-database-name NOT THERE
Using a Samsung Galaxy Nexus for testing, not the emulator. The Nexus does not have external SD memory card.
SQLite databases are only accessible to the creating project, but is there a tool that can access it externally? I have sqlitebrowser (awsome) i will try if I can find the file.
I would try to Root the Nexus, but I can already see /Data/Data/ other items/Data/their data, so hopefully I do not have to go that route.
You're not able to access any contents of /data/data if you access it from adb shell without first rooting the device. Shell is considered as another app (more precisely another linux user), so it's prevented from accessing other app's data in /data/data.
Root the device or use emulator to see the data.
Personally I really recommend rooting the device for development.
So I want to prevent people from copying files out of my app while it is running.
1) Is there an easier way to detect if files are being copied off my device than through checking if the adb daemon is running?
2) Is there an easy way to enumerate all processes running on the Android OS from an app?
I know Android is not a very secure system, but I would at least like to make it difficult for people to copy files off of my app.
EDIT
To clarify my problem, all the files I have stored on the disk are encrypted. My concern is that I need to unencrpyt these files when accessing them in my app. I am trying to prevent someone from stealing these files while the app is running. I already delete the unencrypted files if someone exits out of the app.
Also, I was focused on adb because I was considering trying to delete unencrypted files if connected by usb. However, I know you can still run adb over wifi on a rooted phone. Now that I think about it, you can probably transfer files over by wifi on a rooted phone as well.
Also, obviously not having the files on the device is not an option.
You seem focused on adb, for unknown reasons.
With respect to internal storage, users cannot copy files off of internal storage of a device using adb, unless the device is rooted. And if the device is rooted, they do not need adb to copy files.
With respect to external storage, that is specifically designed to allow any app, or the user, to copy files from it, again without adb.
Hence, trying to detect adb is pointless.
I know Android is not a very secure system, but I would at least like to make it difficult for people to copy files off of my app.
Then don't put the files on the device in the first place.
I'm not sure if you mean that a user would use your application and put his phone on USB mode and proceed to transfer file off your application folder while your application is still running ?
If some files are needed in order for your application to function at runtime, can't your just make them private to your application ? Like illustrated in this article. Or simply don't put files on the device :)
I'm not sure what "copying files out of my app" means (is your app designed to show/provide files, or are you referring to the resources and other files used by your app).
In any case, you're wasting your time. Android is a very open platform and (particularly on rooted devices) people will always find a way to copy data if they want to.
I'm trying to debug an android application's database on a real phone. Where can i find any individual application's databases on a real android phone?
Similar to /data/databases on the emulator i tried searching under the /data on my atrix, and i don't find anything under it and i would like to debug databases on the real device.
A second question is does the contact app stores the data at google servers (right / wrong). I beleive this would be the case, but was wondering if they also cache the contact databases in every individual phone to speed up access. please correct me if i'm wrong.
I believe the databases folder is still there on your real phone, but you don't have access to it due to permissions. Database files can only be accessed by the app that owns them so you can't browse all of them unless you have root access.
The contact app stores data on your phone's internal memory so that you can access it without an internet connection. Some android devices (e.g. tabs) do not have internet access, and it's possible to query your contacts list using these devices.
I could not find the sqlite db file of the application that I am developing runs on a tablet (not on emulator). Please anyone share with me that where does android keep db file of an application. And how do I export it to the computer? And finally is there any tool that can parse an sqlite expression even if it has no db or table? I mean it will only check the phrase and will say the phrase is available to run or not.
Unfortunately, application's database files are not available on non-rooted devices. You can either use a rooted Android device, or Android standard emulator, or Genymotion (see https://www.genymotion.com) in order to be able to access database files of your app.
It keeps it in a private embedded linux folder that's based on your application name, but that only the userid of your application can access.
There is no way for you to copy that file directly unless you root your tablet. In the emulator, that file is directly accessible, but the emulator is a special case.
That being said, there is a programmatic way to pull out the data from that database and reconstruct it on the SDcard to pull it back on your PC (that solution is not perfect, but at least it's better than nothing).
Nope, You can't access the DB of the device (eithr phone or Tablet) via ADB or any other third party Eclipse plug-in.
This was restricted because of security, but you can access it if you root your Tablet or Phone, which is again most people don't prefer to do.
or you can choose to make the db in sdcard (which recomended when the db is too huge).
