I have created a directory and even a file in that directory on the external storage, I am able to read and write into that but the problem is they are not visible on the emulator i.e, in the phone.

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.
Is it possible to create files in subdirectories created under "/data/data/packagename/files/" directory using openFileOutput method in android?
ie there is a sub-directory by name "text" inside the "/data/data/packagename/files/" directory.
I want to use the openFileOutput (String name, int mode) method to write a file eg:sample.txt into this directory....Is it possible to use openFileOutput method to do it....

Is there a program for the Android OS that allows to to access your files and directories, like 'Windows Explorer' does on your desktop pc? I have some audio files that I would like to move to the ringtone directory.
View 4 Replies View RelatedI have images uploaded on the simulated sdcard on my emulator. I downloaded them from the browser, using the long-click on each image.
When I look at the file explorer in the DDMS perspective, I see that they are in the directory sdcard/download.
Now if I want to download some audio files and use them in an app to, say list the title of all audio files, will they go in the same directory? (I am trying to push the audio files manually from my computer to the emulator).
This doesn't seem right. Shouldn't the media files of different types (pictures, audio, video) go into different directories?
Also, thinking this through a little, how is something like this related to the physical directory on the sdcard?
Uri mMedia = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
I'm storing my Android project in a Subversion repository. After recently shuffling a bunch of stuff around I started getting tons of errors like: syntax error entries/project_name/src/.svnline 1Android AIDL Problem syntax error don't know what to do with "" entries/project_name/src/.svnline 28Android AIDL Problem etc.
It seems as if Eclipse is trying to build the files in the .svn directories now. This setup used to work fine.
I've experienced a strange issue running applications on the HTC Desire.
When I call getApplicationContext().getCacheDir() or getApplicationContext().getFilesDir() from my activity this always returns null. In the emulator /data/data/com.myapp.android/cache respectively /data/data/com.myapp.android/files is returned.
Because of that I'm not able to use the webview class as it tries to create cache files and crashes with a null pointer exception. The logs:
CODE:..............
I noticed that other apps have issues as well. For example the google finance app logs the following message:
CODE:.............
Why I cannot create folders in this directory?
Is there a possibility to set the fileDir and cacheDir paths to the sd card or somewhere else? I looked at some classes like Context, Webview and CacheManager but I could not find a way to change it.
Do I need to set a permission to create cache files?

I may opt to buy a larger 16GB card for my Dinc to replace the 2GB card that came with it that I've been using for weeks. Will it just be a matter of copying all the files and directories from the old card to a temp folder on my PC and then copying them back to the new card once installed in the phone? Don't want to lose what I already have on my 2GB card.

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?

View 2 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.

2. Reset the entire phone.
3. Uninstalled the mmx driver on my PC and reinstalled it.
I have purchased iball slide 3G 7271 ( 3G model ) (Android version 4.0.4) in India. Available Interneal SD memory 2GB.I have external micro SD card slot expandable upto 32GB.

In order to use my external SD card for installing the games and other things....
I have gone through Google search and found ""FolderMount "" software and downloaded to my tab.
I have installed also. It was successful.when I open FolderMount, it says......""serching for root "" ( with one EXIT button to cancel)....and doing nothing beyond that.
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.
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?
