Are there Android API's to access data from an external USB device, such as a hard drive? I need to write an app to interface with an external usb device, is this possible? What system calls are used?

I'm running a custom ROM (4.2.2) on an HTC Vivid. When I connect to my PC via usb, Windows only sees the internal storage, not the external sd card, and there's no way to navigate to the System partition to access.
When I was running the stock HTC ICS, Windows would mount the external card as a separate drive. I know the file system hierarchy is different with JB. Is this why it only sees the internal storage now?
I have a NAS storage unit setup in a wireless workgroup I just wondered if anyone new of any way to access the NAS units files from my phone.I have a HTC Desire running Froyo.

I'm trying to find information on how to programmatically access the HTC Droid Incredible's supposed 8GB of internal storage.To determine the external storage (SD Card) location, In examining HTC/Google Nexus One, Motorola Droid, and HTC Dream/G1 phones, there (as would be expected) does not appear to be any mount point for such arbitrary internal storage. On these phones the internal storage is divided amongst /data, /system, and /cache partitions. The Incredible's internal storage is certainly not going to be located in /system. /cache is also unlikely given that it is globally non-readable/non-executable. I'd read in reviews that the phone will still be limited to 512MB or so for apps, suggesting that it is not simply a subdirectory of /data.

I have a project I'm working on, but I'm stuck on that part.The goal is to plug my DSLR into the phone's USB (I made a specific cable to do just that) and access the pictures from the phone, then with my phone running an FTP server app broadcasting over WiFi, access the pictures on my camera from my computer.I'm stuck on accessing the files on my camera from Android. Is this even possible?
View 8 Replies View RelatedI can't find a way to access the internal 8GB storage from the phone to put files there, or to open/use files there, for that matter.I can see it from the PC if I mount the Droid, but can't from the phone itself.please point out the obvious thing that I'm missing. I've tried Astro, Root Explorer, and the Files program that came w/the D2, none of them appear to allow me to access the 8gb storage.

It detects the two internal memories, but the moment I access them; it says please insert the disk in the drive. What might be problem here? The memory shows as mounted in the phone.Also, Kies application does not appear to be working on Windows 7 64-bit. It does get installed properly, but does not detect the Galaxy S.
View 7 Replies View RelatedI've started seeing some apps that offer to read/write data to the internal phone memory (like Super KO Boxing 2, which offers to save a whopping 52MB to the phone memory). I suppose this is because newer Android devices have a lot of internal storage, as opposed to my devices, which have very little. I would like to support internal storage in my app as well.
But it's a bit difficult to implement a solution to something that I don't really know how it works. For example, do these newer devices allow users to upload files to the internal memory, like it's possible to do with the SD card? Can someone explain internal storage from an user perspective and recommend strategies for supporting read/write operations both for internal and external memory (ie: letting the user choose which memory to use at startup, like the Super KO Boxing 2 app)?
I have a question about where people expect me to store my application data. I have an application where the user will enter information via the keypad, and download information (including images) from a website. Where is the proper place to save this? Internal or External Storage?

View 1 Replies View RelatedI would like my Activity to be informed when the SD card is removed, since it relies on files from the SD card (to keep apk size down) but for compatibility reasons is not targeted at Froyo. I'd like to close the application when the SD card is removed/mounted (giving the user a dialog message to inform them of course) so that I don't get IOExceptions etc (I'd quite like to not have to check everytime I load a file to see if the external storage is available, I already do a check on application launch). There doesn't seem to be any attribute in the manifest for this (like configChanges) that I can find.
View 5 Replies View RelatedHow do you check if the SD card is full or not so that your application can decide if it can continue to do its job i.e. write to external storage or notify the user that storage has run out of space.
View 3 Replies View RelatedIt'd be convenient if an application I'm writing stored some files to external storage permanently (so they persist after the application has been exited[destroyed]), but on an uninstall I'd like to do the decent thing and have these files removed to free up the storage.
Is there any way I can have these files removed on an uninstall?
If there isn't (and I'm skeptical), then I'll have to create these files each time. I'm trying to save start-up time and also occupy required space by having them exist permanently.
Note: I need to use external storage, so both internal storage or a DB would be inappropriate.

How do we get Google to support this? Most other email applications support it, but as a Google Apps Enterprise user I want and expect the native Android email application to work.I use external storage on a Galaxy Note 10.1, Galaxy S3, Razr Maxx and Transformer Prime.
So I have this GT n7000 with android 4.0.4 ICS, rooted. I want to swap my 32 gb external sd card with my internal one. I googled it, found a method that included replacing a vold.fstab file in system/etc but that was only for jellybean. I need a method for ICS. Also I can't understand what usb storage means. Is it different form internal sd card??

The phone has only about 300mb internal storage and can barely handle its own updates(because of the limited storage). so i would like to know if its possible to make the phone "think" that some of the sd card is part of its internal memory?

View 3 Replies View RelatedI've bought this chinese clone of the SIII, it's a MT6575. It's great except for the internal storage, which supposedly is 500MB but there seems to be an invisible SD storage which is 2GB. It's really confusing... When I go to Settings -> Storage there are 3 memories: "Internal Storage" (claims to be 4GB but it's fake, it's actually 500MB), "Phone Storage" (claims to be 16.5GB but it's probably 2GB), and finally my SD, "SD Card" (32GB).
The thing is, I'm having problems downloading big apps because apps go to "Internal Storage" which is 500MB only, and which files are stored in the "Phone Storage" (maybe internal & phone are actually the same?). However when I go to Settings -> Apps, on the "Downloaded" tab, the apps are in "Internal Storage" (500MB), and on the "On SD Card" tab, it shows that apps are in "Phone Storage" (the ones I moved to SD). This means my 32GB SD isn't being used by the system when I send apps to SD probably.
Also, my 32GB SD card is found in /mnt/sdcard2, and the /mnt/sdcard... I don't know which storage is that.
So basically all this is happening because I tried to Link2SD with my 32GB SD doing all the 2 partitions stuff and so, but Link2SD never detects the "secondary SD" which is the 32GB SD, as this fake SD card, "Phone Storage", is probably what the programs thinks to be the SD card.
