Android :: External USB Storage

Apr 30, 2010

Is there a way to access an external mass storage device from the USB port of an Android phone? 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?

Android :: Internal Memory And External Storage

Aug 18, 2010

I'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)?

Android :: Internal And External Storage - Force Close

Jul 6, 2010

I have an app that accesses music and I had at least one user complain that some of his songs are on internal storage and that causes a force close. My question is do I have to do 2 calls for each song now or can I make a query that will look at both the internal and external memory?

Android :: Activity Get Notified When External Storage State Changes?

Jul 24, 2010

I 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.

Android :: Check Availability Of Space On External Storage

Jul 2, 2010

How 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.

Android :: Way To Delete App Associated Files From External Storage On Uninstall

Jan 1, 2010

It'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.

Android :: OutOfMemory Exception When Loading Bitmap From External Storage

In my application I load a couple of images from JPEG and PNG files. When I place all those files into assets directory and load it in this way, everything is ok:

CODE:..................

But when I try to load the exact same images from sd card, I get an OutOfMemory exception!

General :: Google MUST Support External Storage

Oct 9, 2012

None of the Google Applications support external storage, Gmail 4.1.2 won't send documents attached from an external sd card, Play Movies & TV won't allow you to specify a external card as a storage location, pinned Google Drive documents can't be stored on an external card, Play Music sucks up internal memory. Try sending an attachment using Gmail from a Motorola Xoom, a "Google Experience Device".

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.

General :: Expanding Internal Storage Onto External / SDCard?

May 8, 2013

I finally upgraded to android, i got the cheapest phone possible(kyocera milano) which seems to be a mistake. 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? I found an adb driver for it(dont ask me where or which one because i had no idea and started messing with one until it worked) i have not tried rooting but can if i need to.

General :: 2 Small Internal Storage - How To Swap SD To Be Main Phone Storage?

Aug 23, 2013

I'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.

HTC Incredible :: Trouble Mounting Internal Phone Storage And Sd Storage

Aug 22, 2010

For some reason my Incredible won't mount both the internal phone storage and the SD card storage at the same time. What I mean is...when I plug my phone into my PC I only get a single popup asking to mount the phone's SD card storage, but not the internal phone storage.If I remove the SD card (or unmount the SD card using menus on the phone) and then toggle the connection type from Disk Drive, to Charge only, and then back to Disk Drive (to burp the connection), the internal phone storage will mount, but the SD card won't mount because it has been removed.When I connect my wife's incredible, my computer sees both the SD card storage and the internal storage (as expected) and gives me prompts for both. I took the SD card from the problematic phone and put it in the "good" phone and there are no issues at all (IE.. both the internal storage and SD storage mount). This of course means there is no issue with the SD card.

Jelly Bean :: Does Extending Internal Storage From Phone Storage Possible

Nov 19, 2013

I bought my new phablet that was powered by 4.1

im shocked with how the manufacturer of my device(cherry mobile) designated their storage. the phone storage is 2gb and internal is 500 mb.

it is not a problem if i could write apps on phone storage by default but even though the 'write to phone storage' is checked, when i downloaded an app, the internal storage still losses free space.

so is it possible to extend internal storage?

Which is considerably bigger than whats left of my internal space.Is the INTERNAL used for Multimedia files as this thread suggests?Internal Storage vs Phone Storage.If so. How come my multimedia files have ended up there, when they've always been saved to my SD card.
