I am trying to create a folder and several subdirectory within it on the SD Card... I then want to transfer files that I have stored in /res/raw to that folder... I addition, I want this to only happen once, the first time the program is ever run. I realize that this is ridiculously open-ended, and that I am asking a lot...

Im tyring to save my file to the following location FileOutputStream fos = new FileOutputStream("/sdcard/Wallpaper/"+fileName); but im getting an exception java.io.FileNotFoundException
But when I put the path as "/sdcard/" it works.
Now im assuming that Im not able to create directory automatically this way.
How to create a directory and sub-directory via code.
When making an image I accidentally had Clockworkmod image be saved to the device itself instead of being saved to the external SD card.
I am able to browse to it using Root Explorer and select to Copy it, but how do I PASTE it onto the external SD card when Root Explorer only accesses the device directory and not the external SD card?
Quick 2nd question: I know on some previous devices such as the Galaxy S 4G you were *not* supposed to run Clockworkmod after booting in and from the Apps Drawer, instead you were only supposed to run directly from the startup screen before booting in. Is it OK to actually start the Clockwork Backup/Restore process from the Apps Drawer of the Galaxy S4 and let it reboot and do its thing or is it only supposed to be run BEFORE booting in?
I try to create 'foo/bar.txt' in Android's /data/data/pkg/files directory.
It seems to be a contradiction in docs:
To write to a file, call Context.openFileOutput() with the name and path.
http://developer.android.com/guide/topics/data/data-storage.html#files
The name of the file to open; can not contain path separators.
[url]
And when I call
this.openFileOutput("foo/bar.txt", Context.MODE_PRIVATE);
exception is thrown:
java.lang.IllegalArgumentException: File foo/bar.txt contains a path separator
So how do I create file in subfolder?
I'm happy reading and writing to a pre-set file, and could manually populate a listview, but I'm hoping there is an official(or not) filebrowser I missed, or other more elegant solution to present the user with a directory listing, and let them select a file.
View 2 Replies View RelatedUsing code from open source MusicDroid with the following code that I found during a search for this problem, I can only get mp3 files that are in the root directory /sdcard/

How can I get all the mp3 files from the card (in any directory) into my 'songs' list?
I have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files.
The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question.
Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it.
Today, I am seeing an error reported:
CODE:................
Regarding the sdcard, I see it has plenty of storage left, but counting
$ cd /Volumes/NO_NAME/.hidden
$ ls | wc -w
9058
Deleting a number of files seems to have allowed the file creation for today to proceed.
Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful.
However, my question is: Are there hard limits on filesize or number of files in a directory?
am I even on the right track here?
Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format.
The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.
Brought over my 8GB Sandisk from my BB. Obviously over the past year it added a bunch of files and folders to the card for miscellaneous app data, music, pics, etc. Would I gain any speed on the device by reformatting the card and letting it start fresh in it's new home and re-syncing music and photos into fresh android directories?

Phone: HTC Incredible still ten days from my hands.
Microittybitty SD card: came in today's mail.
Computer OS: Vista
Music: On iTunes.
Downloaded: doubleTwist
My general media skills: Sucky.
Ok, here goes. So I have this fear that I won't be able to get all my lovely music from my computer to my Incredible. This is not an irrational fear, as I am notoriously bad with any kind of file management. And device management. And getting devices to talk nicely to each other.
(You may heckle me all you want. Yes, I am in over my head here. This will be an adventure.)
If I could figure out how to copy my music files to my SD card, could I then just put the card in the phone and have the stock music player recognize them and all that? Or would I end up down some dead-end street by myself in the middle of the night, drunk and dazed?
I want the music to go to the SD card anyway, whether I wait for the phone to get here or not. I'm just trying to skip a step. Will it work?
Has anyone managed to copy a file such as an Excel spreadsheet from googlemail to SD card ? You can preview in googlemail but to open you would need to use I think quickoffice which insists that any files it opens are on the SD card.
View 4 Replies View RelatedWas thinking about upgrading my stock 2gb card to a 16 or 32 soon. So I have a few questions.
1)Since my Dinc is rooted, will I have to copy anything to the new card after formatting it, or should my phone remain unaffected?
2) I know there is class 2, 4, and 6, with each having faster read/write speeds and being quite a bit more. Will those speeds really make much difference when being used in my phone for backups, random files, apps, and music or videos?
3) Can I copy my sd card files to my phone's internal memory and transfer them that way? Or do I need to transfer them through my computer?
At some points while running my android application, I need to create a directory on the sd card, for a small number of users this fails and I can't figure out the reason for it... (I've found similar problems caused by the WRITE_EXTERNAL_STORAGE permission missing, it's there and it works for almost all users so I don't think this is reason) When mkdirs returns false I crash the program and log the following java.io.File properties, starting at the directory I want to create, then recursive printing properties of the parent directory and so on...
/sdcard/MyDirectory/Dir1/Dir2 (exists: false, canWrite: false, isDirectory: false, isFile: false);
/sdcard/MyDirectory/Dir1 (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard/MyDirectory (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard (exists: true, canWrite: true, isDirectory: true, isFile: false);
/ (exists: true, canWrite: false, isDirectory: true, isFile: false);
The strange thing is that the parent directory is writable (canWrite=true), I can't print the execute file permission but from what I've read, write is what you need when creating directories... What I've looked at so far is the WRITE_EXTERNAL_STORAGE permission, if the sd card is full and if the sdcard is mounted read only:...........................
I've checked related posts and this question specifically pertains to the HTC Hero Sprint CDMA phone. Before connecting my phone to my PC desktop computer, I want to verify if this is the correct method: Question May simply connect my USB cable from my HTC Hero into my USB drive into my PC desktop? Will this pop-up the files, directly, etc? May I simply Copy/Paste the file(s) (pictures, etc.) into a file on my PC desktop hard drive? Is there simply a folder with my Micro-SD card files? Are there any other folders of files, etc. that may be on my phone which may be copied as well (i.e., Apps, etc.)? It's interesting to note that if an iPhone or iPod Touch is ever lost or misplaced, everything is backed up on iTunes on an external device. I suppose if I lose my phone, I'll have to start over. Correct? Or is there a way to backup Scenes, downloaded apps, customizations, etc.?

View 1 Replies View RelatedI am new to Android and creating my first application.I want to create a file in the current directory. Basically I have a file bundled with aplication package as raw resource. I want to make a copy of this file in the current file. The reason to create copy in current directory is that I want my file reading code in native java, portable code.So my query is how can I create a file on current directory? The location current directory is important here as I do not want to make use of device specific hardcoded path or any Android API while reading the file. This is so I want my file reading code portable.
