I have a service that needs to write some data to the internal storage using RandomAccessFile. Do I need to use a WakeLock to make sure the data won't get corrupted if the service process gets killed?

I have a xperia u, which has not external SD card slot..
Data partition is MUCH bigger than what I need (I'm using 500mb of 2gb) and I want to move obb files to data partition to free some space in SD partition..
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?

I have an application with a lot of media data (images and videos) that were previously stored on the sdcard. With that, images and videos are displayed fine in my app.
Now, in order to secure the content more, I wanted to move the content to the internal storage / data dir of the app, which I did. I copied all media with a routine within my app to the data folder (/data/data/com.myapp/some/folders/video.mp4) and adjusted the path in my app so that it would look for the media in the internal storage data directory and not the sdcard anymore.
Everything works fine, images are being displayed (decoded) properly, but videos don't play. They files do exist though - I do not get a FileNotFound exception. But an IOException: java.io.IOException: Prepare failed.: status=0xFFFFFFFC
Why is that? Everything is handled within my one app and the videos have been copied with the same routine as the images, thus having the same permission settings. Looking at the stack trace, it all runs in process id 18060).
Why I cannot playback the video from internal storage? Or how can I?

View 1 Replies View RelatedI have a UnRooted Desire HD running 2.3.3, and recently I got the "Low on Space" icon. Upon checking my apps and there size I only have 240ish MB of apps. So I deleted some apps and got 144MB of free space. Then over night my phone went from 144MB down to 8MB of free space (phone was on the charger and wasn't touched all night).
I did download an app called DiskUsage and it shows a very detailed view of whats taking up what space on either the SD or internal storage, and is showing me that my System Data is using 885MB of internal storage space. A friend has the same phone and he got the same app to compare and he only has 90MB of system data. I Hard Reset the phone and hope it doesn't come back, but I would like to know how to correct this issue if it was to happen again.
My wife has a completely stock 1.5 Eris. She's getting a low storage notification. I looked at the system setting and her internal storage is completely maxed out, but the SD card is 90% available.

She only has pictures on her phone, not a single song, movie, video, etc. How do I get the data moved to the SD card?
View 1 Replies View Relatedwiping my contacts and SMS. How do I go about recovering deleted files from internal storage (NAND)? And which files do I need if I only want to recover my contacts and sms?
attempting to recover them by following different tutorials, but no dice. Ive read an article where people were saying that if I take too long, I will not be able to recover my data.
This phone was my dads until he got a new one, but he only has a limited amount of time to retrieve the data before it goes back to T-mobile or else he has to pay money for the broken phone core. It was dropped, and broke the digitizer but not the screen. As of now, the display doesn't work at all, but I can hear the phone turn on just fine. I have been trying to think of how I can access the internal storage without tearing the phone apart and getting to the storage directly(not sure if that would work either).
- Model Number SGH - T989
- Not rooted
- USB debugging not enabled. I thought I might be able to get to the storage via adb, but that will be useless without usb debugging activated.
I have a service that acts a download manager, downloading files in the background. I have aquired a partial wake lock while the downloads are going. When the downloads finish, I manually release the wakelock. Because I am paranoid, I acquired the wakelock also with a timeout. The problem I am seeing is that if I have already manually released my wakelock, when the timeout period expires an error is presented to the user (and adb logcat shows an under-locked wakelock exception).
Is there any way to use a timeout (as backup wakelock release in case the app force closes for some reason) without getting this error?
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.

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.

View 1 Replies View Related1) 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?

View 1 Replies View RelatedI have a Motorola Droid that isn't rooted. In the last few weeks I've had problems with dropping free space on internal storage. I'm around 30MB free but it drops almost daily. I have deleted pics and text messages and have started deleting apps but the free space keeps dropping.Is there some way to figure out where this space is going or monitor for changes?
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)?
I have used the android internal storage to save a file for my application (using openFileOutput) but I would like to delete that file, is it possible and how?
thanks maxsap.
Is there a way to set the emulator's internal storage size? It is currently set to a fairly low value. Also, while searching for the answer to this question (which I didn't find), I ran across several threads which seemed to indicate that many phones have a very limited amount of internal storage. If I have an application which is 30 Mb (due to graphics and audio resources), is this going to be too large for most people to use. Should I be looking to install my application on the SD card instead (can this only be done on version 2.2 systems?).

View 1 Replies View RelatedI'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?
