I just want to view the files(especially the .png files) associated with one of the application in my mobile. The application is actually installed(moved) in the SD card.
The issue is ..I could not find the application in the SD card. I am using a file browser called 'File Manager' to browse through the SD card. Can someone help me on this.
It should be here:
/mnt/sdcard/Android/data/your_package_name/
Some hardware implements the path to the external storage different.
/mnt/sdcard/Android/data/your_package_name/
/mnt/sdcard-ext/Android/data/your_package_name/
You may be able to get a better view of what is on the device by using the ADB Shell. If you still have trouble at this point trying running grep or find from the shell.
UPDATE
Most of the time the files associates with your application are in the directory with your application. The application is installed in /data/data/your.package.name/. However you will need root access to get here if you are on a phone, I think the emulator lets you get here. As far as external storage... yea its a pain, to much fragmentation in the market. You have to programmatically check the location of the external storage.
On my device with Android 2.3.6 apps moved on the SD card are located into a directory named .android_secure as .asec files (see http://www.fileinfo.com/extension/asec).
They are not visible from the standard "Archive" browser which shows the hidden directory as empty.
The files are also encrypted so I guess no access to the images within is possible.

On my Samsung devices I put a file in the /Download folder. When I select the file within my app (via a file browser), the file is called /storage/emulated/0/Download/myfile.db. This name is stored in my app settings.
At the start of the app the file should be opened. First the app checks if the file exists. In some cases, say once every 2 weeks, the file is said to be not existing! This happens also at my friends mobile since half a year.
Why is that happening? For years everything ran smoothly.
This code runs for 6 years. Of course I added the permissions stuff.
Your help is much appreciated!
You can't use the Download as an guaranteed storage place for your files. You should use the Internal storage for the app. This is what Google has written about the download folder:
This space is called external because it's not guaranteed to be accessible—it is a storage space that users can mount to a computer as an external storage device, and it might even be physically removable.
Here you can read more about the Internal storage and the External storage in Android.
Here is some more information about the Download folder from Google.
Caution: The external storage might become unavailable if the user removes the SD card or connects the device to a computer. And the files are still visible to the user and other apps that have the READ_EXTERNAL_STORAGE permission. So if your app's functionality depends on these files or you need to completely restrict access, you should instead write your files to the internal storage.
When I download a pdf file from the Android app, I do not want the user to be able to find it on the phone. Is there such a hidden space on Android phones? I have tried putting a dot in the folder or trying other solutions from the internet but they can reach the windows computers when the phone is connected to the computer via cable. Is there anyone who can suggest a solution?
You should avoid having that file on the external storage completely.
Simply use getFilesDir() for that.
Use the device's internal storage as described in the android docs.
Files stored on the internal storage are only visible to your app and removed when your app is uninstalled.

I have an app I made on my old phone. It creates a folder called LocationTracker. When Im stepping through the code it says the folder exists. But I cant seem to browse to it when I connect my phone to the computer. I just checked my file explorer on my phone and i can browse to the folder there as well. According to that it is under the sd card, but i just cant see it on my PC.
Im rooting around in my file explorer on my phone. There appears to be 2 sd card folders. One is called sdcard1, and that seems to be my actual sd card. The other is called sd card. I think its an emulated one. I use Environment.getExternalStorageDirectory(), i thought that returned the sd card if one was available. If that is the case why is it using the emulated folder instead of the actual sd card folder? How do I fix this?
From Android documentation:
In devices with multiple "external" storage directories, this directory represents the "primary" external storage that the user will interact with. Access to secondary storage is available through
The rest of the sentence is sadly missing. However the methods are Context.getExternalFilesDirs() and Context.getExternalMediaDirs().
I am working on a project that needs to store some .txt to android, and get it from the computer for other use. From what I read from the documentation, I know that there are two types of storage: 1 Internal, which is somewhere deep in the phone that is private to the app. 2 External, which includes the SD card and the Internal Storage of the phone. I want to store it to External->Internal, and I am using this line of code to do that:
public String WalkDir = android.os.Environment.getExternalStorageDirectory().getAbsolutePath() + "/Walks/";
When I logged WalkDir, LogCat says "/storage/emulated/0", I stopped the app, checked with the adb shell, and there is no folder "0" but "legacy". I unplugged the phone and plugged it back in, the "Walks" folder is now in the root directory, and I don't need adb shell to access it.
So my question is, can you help explain how this system works? Why did "0" disappear? What is "legacy"? Why is the file in Internal Storage when I unplug&plug it?
Thank you very much!
Those are what in Linux are called symlinks (like shortcuts in Windows) that various system apps in Android are using..
/storage, /sdcard are sym linked folders,that means when you open one of those, it redirects to the original(/data/media/0), as for the 0 is just a multi user feature implemented in android 4.2, but only enabled on tablet androids.
Why do this Sym-Link?: simple so it dosent break apps(not only file explorer type of app, but all apps).
Still dont get, why it would break?.Simple. android api have lots of ways to write/read files from folders, u can do manually,u can get the data path, u can get the sdcard path, etc,etc. so to not break that they just does these sym links, thats why in one app the storage contentents are listed on /sdcard but on others, is /storage, etc,etc. one example of an app that broke because of these changes to android is titanium backup, u need to change the internal storage on it, so it work.
2 mount points pointing to the same storage device and partition.
If you create something in one folder, it will show up in the other. Same applies for deleting stuff.
They do not take away more storage space, as it is only available once but shown twice.
You also don't need to worry about it in any way because file browsers normally set their default directory to one of these locations.
As far as i know, Google changed the mount points in Android 4.2 to /storage/emulated/0/ due to them switching to MTP and EXT4(?) for the sdcard. The other mount points are still there for compatibility.
I have created an app which lets the user save an image to the sd card, but I cannot see it in the gallery app on my emulator. I'm not sure if I need special code for this or what but I need to be able to find it so that I can see if my code actually works.

If your ultimate objective is to see the files on the SD card, then that can be achieved in several ways:
Use file explorer that comes bundled in Android Debug Monitor.***
Login to device/emulator shell, adb shell, and navigate to SD card folder (that's usually at /sdcard or /mnt/sdcard) and use ls command to list the contents.
Install/use one of many available file explorer apps and navigate to SD card through the device/emulator UI.
***Example:
Launch the ADM by running monitor command (if the SDK tools is not in your path, then first navigate to tools/ directory).
There will be several perspectives: LogCat, Threads, Heap, etc. You need to switch to File Explorer tab.
Above is File Explorer view for Galaxy Nexus, the actual path for SD card may differ for your device/emulator.
You need to add the File to the media Library look at the MediaScannerConnection. You will need to call the ScanFile (after connected) and then the image will be added to the gallery.
