The VS emulator does not seems to be showing the SD card in the storage menu or through code. any idea how to get it working. even if we go through the SD card menu on the emulator options and provide a folder it doesn't seems to be working.
I first had to 'Pull from SD Card' which seemed to create the required hierarchy under the folder I identified. Then I did a 'Push to SD Card'. Still didn't behave entirely as I expected since no external storage was listed under settings. I just was trying to copy files across and this allowed me to do that.

Im using the latest version of Android Studio and it won't allow me to add and external SD Card made with "mksdcard". In previous versions this was possible but now it just reverts to blank every time I try to add a new SD card.
Anyone face this problem or know how to fix?
One of the issues that the Android forgot to mention is with Android Studio 3.0 when you create AVD you need to now create an image for the SD CARD with the
mksdcard tool to create a FAT32 disk image. After you use this tool then when you are creating the AVD you will see under advanced view the SD CARD area the
External files click that and navigate to where you stored the sdCard.img file you created with mksdcard tool.
Here is a bonus trick USE WITH CAUTION you can tell that emulator that it has the SD CARD ejected by changing this value hw.sdCard=yes in its config.ini file from
yes to no. How to find the config.ini file
Windows Explore find the android/avd/device name open the device name file then
with a FILE EDITOR like Sublime Text make the change to hw.sdCard=no and do a
SAVE AS I suggest you not use MS notepad to do this
I was facing the same problem today and found your question here on SO.
I was able to solve this issue by finding the config.ini file of the AVD itself,
and by editing it manually (e.g. with Notepad). On my Windows 10 machine the file is this one.
C:\Users\peter\.android\avd\Nexus_5_API_25.avd\config.ini
In that file I had to manually edit the value of this property as follows.
sdcard.path=C:\Programs\Android\SD_Card_Image\SD_Card001.img
That seems to make Android Studio to not revert back to a blank external file name.
EDIT:
The weird thing is that even you specify an external file for your SD card image (as opposed to a studio managed SD card), that doesn't mean the AVD is using this exact file which you specified. Seems it uses it just initially (for initialization). Then Android Studio creates a copy of the image file somewhere (inside the AVD folder it seems) and from there on it uses his own copy. That was quite a surprising behavior to me. I even find it buggy. If that's what's intended, then what is the purpose of having the option to specify an external file?
That page does the same to me for "Device Frame" checkbox. It's always unchecked even though it does apply the skin.
So check first whether you can access the SD as you're supposed to.
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 aware about changes in Access to SD card introduced by Google with Android 4.4. However in my application I need to be able to store data on some removable /secondary sd card.
When I create the application folder (app.xyz.com) on the secondary using default file manager then I am able to create dirs and files inside. But by default such dir dosen't exist on secondary sd card.
So, I would like to create the application specific dir programmatically inside my application…
Do you have any idea how to do this??? Simple file.mkdirs(), even with the correct application related path, doesn’t work. Permission error…
I have spend already two days trying to find a way, without any success
THANKS FOR YOUR HELP!!!
Do you have any idea how to do this?
Use getExternalFilesDirs() (note the plural). If that returns more than one entry, the second and subsequent ones are on removable media. Those directories you can read and write to without any permissions on Android 4.4.
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.
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.
