Folder Directory - How To Organize Files
Jul 11, 2012
I've thought of starting to develop an application and one of its features is that it downloads some content (images, files, etc) and organize them into folders in accordance with site they were downloaded.
Well, the question is... How do Android organize your files? In Windows, for example, I could create some folders, one for each site, or one for each time period. But in Android, how does it work? Is there a system of folders like Windows? Or is there a totally different way to organize files?

So this may be a silly question. Folders are great for organizing like-apps, like Games, Utilities, chat etc. I know how to rename folders but is there any way to organize apps once they're IN a folder....or can you only do it by the order they were dropped in there?

Can anybody advice what is the recommended directory to store files generated by your application: audio files, video files or some images.
If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?

I'm storing data on SDCard and want to get the size/length in bytes of all the files in my main folder and sub folders. How can I calculate the length? Is there any other way to calculate other than open every file and get File.length(). length function returns 0 on directories.

I am working on an android app. Where i need to parse some plist files from assets folder. I do understand how to use assets in android but now problem is that file sizes are more than 1MB and so android gives error Data Exceeds UNCOMPRESS_DATA_MAX (2183588 vs 1048576). how to access such larger files from assets? Also I cant reduce a file into small buffers because i am just sending it to "DocumentBuilder.parse(in)" as a whole so can not use buffer. The error is on line: Document doc = db.parse(in).

I uploaded about 50 pictures from iPhoto (using a Mac) just to see what they looked like and then later formatted the Droid's SD card, so the pictures were no longer there.
Now, if I mount the Droid via USB and view the file structure there is a folder named /albumthumbs which contains 50 files, presumably for the 50 pictures a had on the SD card.
To me, these file, unless linking to actual photos stored on the SD card, take up extra space in the phone's memory (not worried about the SD card). I wonder if I can safely delete them (just the files...not the folder)?

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 am updating an app i developed so that it downloads xml files it needs for content management. the files download successfully to the emulator but are not placed in the /files directory that openFileInput() is attempting to read from. i am admittedly unsure as to the proper overall solution here - app originally used packaged XML and was fed to an XMLPullParser - but i cant even get as far as attempting to parse new XML at present because my app cant find the new file sitting in /data/data/[myApp]/ and not /data/data/ [myApp]/files and i cant figure out how to get it in there. the download doesnt work at all if i add that folder to path.e.

I'd like to know if there's a way to write files into the main directory just before the system shutdown, something like this:
End all processes (-> unmount disks?) -> mount /sdcard rw and / rw -> copy files from /sdcard to / -> unmount disks -> shutdown/reboot
Same with boot image (flash, in this case, and not copy / mod files)... is it possible? Or do I require to boot into recovery for these operations? I know I can remount as rw my system directory via ADB
Also, is it possible to do the same thing with the build.prop file? This, or during startup (before mounting partitions with standard permissions).
Of course, this having root (but not a special kernel to enable this kind of "before mounting" thing).

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?

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.

I have a question about moving files after rooting, installed supersu already and give root browser permissions in supersu.
I have a problem with moving a apk file from downloads/direct to system/priv-app. It says after i'm trying to moved it "failed operations" and it seems like it's the only directory i can't move files to.
I have read that the files or directory should have some special permissions, but i'am sure that the criteria are met.
Also when i go to supersu to see logfiles on the "action" it says that i need supersu pro to move that files. But will it works or what should i do to get this to work?

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...

I went to Google Labs and looked around and found Places Directory. The page shows a barcode and said I could scan that and download the app so that's what I did. My browser opened up and showed that the file was downloaded.
So I went back to the home screen but couldn't find Places Directory. I decided to manually download and install it from the market and that worked fine.
My question is, do I now have a downloaded copy of this app that is just sitting somewhere taking up space? I can't figure out where files downloaded by the browser go to, please help.

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.

Can an android project in Eclipse be configured so that the built-in builders read from an alternative source directory? ie. "test/src" instead of "src"? and possibly even "test/res" instead of "res"? (It appears that setting dirs in the property files will only affect ant and not the built-in builders)
