If I want to read/write external storage, like usb drive, does Android provide this feature to do? Or how do using Google API to read/write SDcard on Mobile? Where to get sample code for this goal?

I am working on a widget and have it pretty much how I like it, but I have one problem. When I package it and install it, it says in the "allow this application to" portion that it wants access to phone calls and storage. I know this will be a no-go if I want anyone to ever use it. I have not set up any permissions. Same thing happens even if I make Hello World.

How is that storage actually assigned to the application? Just by package name or also somehow bound to the sign key of the app?
Let's say I have installed application 1 and then write another application 2 with the same name and package name (just differently signed with different keys) and install it (app 2 replacing app 1), would that application 2 get access to the /data/data/[app]/files ?
Or would I not even be able to replace app1 with app2 due to different sign keys in the first place?
When I connect my phone to to my Windows XP laptop via USB, I no longer get asked what type of connection (i.e. "Charge only," "Disk drive," etc.), even though "Ask me" is checked under the phone's Connect to PC settings. The USB icon doesn't show up on the notification bar either (though the battery icon shows it's charging).
On the laptop side, the 2 drives (SD, phone storage) do show up in Windows Explorer (as previously), but when I choose either, I get "Please insert a disk into drive F:." (or G:).
I've tried setting the phone's default connection type to "Charge only" and to "Disk Drive" but the behavior is the same either way.
This might have started with the Froyo update, but I think I've had it working since then.
So the other day I was trying Cyanogenmod 9 on my galaxy pocket, however I didnt realize it wasn't an official release and it was REALLY bugged and I made a huge mistake because i forgot to install CWM. Thing is installed this rom and I belive i pretty much bricked my phone because now I can't get access to any of my networks, wi-fi, bluetooth, or usb mass storage or my sd card are not being recognized either...
What I've tried so far was sending the stock rom through Quick ADB Pusher, but it tells me that even though my phone appears to be root It wont allow it to access, then I tried different ways to root and unroot because apparently SU is not giving me the permissions. So finally tried my last option with ADB and was trying an adb push but I keep getting permision denied if I send it to /root or read only file if I send it to /system also tried Asb shell $su but I keep getting a denied message.
Does anyone know how to access programatically the internal(flash) and external(sd card) storage values such as space used and space available? I cant seem to find an api anywhere?

View 1 Replies View RelatedInitially all worked OK. But then after some installs from the Market i am not able to access any internal flash storages. Phone was not rooted.
Here are some facts:
- i see the drive letters assigned for both of them on PC but when you click Explore the message is "Please insert a disk into drive M: (or N or whatever)".
- They are shown as mounted on the phone . Dismount and mount again changes nothing
- the phone is recording photos/videos OK on internal memory means flash is working fine.
- SD card is perfectly working too. if you extract it and put into computer you can read/write it. On the cell you can play music from it etc no problems
- I restored everything with Factory Data Reset but things did not change
- Same story from another PC
- Samsung Kies shows the files in PC Windows Media Player which are on Vibrant's SD card but can not read/download them
Is this some driver problem ? Or flash memory is locked by Vibrant OS?
I suspect EasyTether or PDANet third party driver for Samsung phones is responsible.
Tethering works though
I have a pattern lock on my AT&T Galaxy SII, but the screen has recently become damaged and unusable. Is there anyway to access the storage on my phone to retrieve files? Hooking up the USB cable does nothing because I can't put in the pattern lock.

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.
i just download some applications from the Market then suddenly got warning phone storage getting low. So is there anyway to transfer the files from phone storage to SD storage ??? PLease anyone who knows about it to inform me coz i stuck with this problem.
View 3 Replies View RelatedFor 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.

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?
I used this to check the amount of space on my A2SD partition of my SD Card. However I've noticed that as well as INTERNAL storage, there's something called SYSTEM 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.
View 4 Replies View RelatedSo if I do a Factory Reset on the phone it still has some of the old photos/videos I took, which leads me to believe it doesn't fully clear the device of everything, just the settings that I changed are returned to their factory defaults (duh!).I was curious if I do the Clear Storage option, which means turning off the device and holding one of the volume toggles while holding the power button - would that mean that the entire Android OS would be removed, or does it mean it does a format of the phones entire partition and re-installs Android (similar to a reformat/recovery partition on a computer)? In which case I would need to reactivate the phone doing the simple *228.

View 3 Replies View RelatedI am creating an Android application which will have some embedded music inside of it ( ~ 80 MB ). I was planning on putting it in the res/raw folder.
Since android stores that all in it's internal memory, is this way too large? What are my options? I have come up with the following:
Copy resources out of internal storage and onto the SD card when application first starts. Afterwards remove from internal storage (is this possible?)
Download music from the web when the application first starts.
I would really prefer not to have to go with option 2 since I want the app to be entirely offline and the static music is not going to change (except between releases).
