Android :: Application Access Permission To Files On Internal Storage
Jun 30, 2010
A question about the internal storage that's private to each application (especially when storing files with Context.MODE_PRIVATE).
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?

I downloaded a file with an app and stored it inside of its internal storage, but the file is set with -rw- and I want to change those permissions so is it possible? I know that using external storage is an option but I want to know if I can do it with internal storage too. If it turns out that I can't change the permission is there some shared region of internal storage that I could use? I would like to not force the Android device user to have an SD card.

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.

Most of the applications on my phone are stored on the internal storage. I cannot figure out how to access the internal storage to manage these applications. I may need to reset my phone, but I don't want to lose my paid applications.

After rooting my phone and using an app called "GL to SD" I am unable to access internal storage, I even did a factory reset and that didn't fix it. I should reinstall that app and use some restore function however I'm unable to install/download apps unless I have .apk file, so any method to get this apk [URL] ......

in my App I want to generate some html files and store them in the internal storage. In my WebView I want to open the generated html by clicking a link. Does a Url to the stored file exist? Something like "internal://mygeneratedfile.html"?

Initially 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

HTC One Does not have external sd card, only the "Internal Storage"
I was trying to multitask and ended up wiping Internal Storage through TWRP. Is there any app / process I can use to recover files? Undelete[app] errors out saying it's not a fat filesystem Disk Digger[app] only searches for specific file extensions, which would cover things like my TitaniumBackup & TWRP Backup files
When I plug it into a computer, it shows up as a Portable Device, and no problem that I've downloaded (Recurva / PCI / EUSUA) is able to search on portable devices, only physical/logical drives.
Is there anything I can do to attempt to get data back from the sd card?

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?

How can you retrieve yours phone internal storage from an app? I found memory info, but it seems that returns information on how much memory your currently running tasks. I am trying to get my app to retrieve how much internal phone storage is available.

I am writing a app that reads a file from the internal storage on startup. I have followed the guildelines here:
http://developer.android.com/guide/topics/data/data-storage.html#file...
It successfully works on the emulator, and I can find the file my app created under
DDMS > data > data > com.MyAppName > files.
Now I would like to install my app on a real device, but do I need to explicitly copy the file onto the device? If so, what's the location should I copy the file to? Or will the file be created when I install my app? I need some pointers or guidelines, I'm quite clueless about the device. Or perhaps if anyone knows any keywords for me to search for an answer.

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.

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.

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?

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.

Does anybody know of an app that can view Microsoft Access Snapshot (.snp) files? I think they're basic images, but a proprietary format. I haven't seen anything in the market that looks like it would do the trick. I get these emailed to me from work and would love to be able to open them on my phone!

I have an app that pulls album art from the media store. It works fine on my N1 and other devices with external SD cards. However, I need to get it working on devices with internal storage and I don't have such a device to test on. How can I set up the emulator to reproduce such a device? I did a search on the forums and found info on increasing the size of the internal storage but I'm not sure how the file system should be set up. Is this even possible?

Does anyone know how to set internal storage in the AVD to something other than the default 92M? I have tried setting hw.ramSize in the AVD's .config file, but no change and also tried setting it when creating a AVD with the "android create" command. Same net result. I'm on Windows XP.

1) Our Android app will store data in a built-in SQLite DB. I see the DB can throw android.database.sqlite.SQLiteFullException, but there's no exact info in API what is the limit. Could anyone tell what are the size limits for a DB in order not to get into the SQLiteFullException? I assume DB will store data in device's internal storage (versus SDCard). Am I right? Given SQLite DB is just a file, probably the DB size is limited with free internal storage space. Again - Am I right? If yes, then what is the internal storage size on Android? How to detect it? Does it vary on a device model basis or OS version basis? 2) We'll also need to save app settings. I think SharedPreferences will fit nicely. However the question is - are SharedPreferences saved to the internal storage too? If yes, then is it the same storage where the DB stores its file?

From the Android documentation:
"You can store files directly on the mobile device or on a removable storage medium. By default, other applications cannot access these files. "
I could write to the sdcard (/sdcard/file.tmp) and other apps could access these files, right?
I would like some local storage that I can write files to (and read from later) that are not accessible to other applications, and I will always have access to. The problem with the sdcard is that if someone plugs in a USB cable and turns on MSC, my application (and all applications on the phone) will lose (both read and write) access to the /sdcard directory. So I need something more reliable.
