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 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 new to android programming, can someone please tell me how to get access to the files in a directory , i am using Environment.getExternalStorageDirectory() method?

View 1 Replies View RelatedFriends, My application has to get current gps position in every seconds and write this data as byte array to a file in files directory. To check the data in that file I tried to open mnually. But i couldn't open. How can i read the file. The file is a text file
View 1 Replies View RelatedI 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)

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.
View 2 Replies View RelatedI'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).
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?
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?
View 2 Replies View RelatedI 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?

View 1 Replies View RelatedI 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.
My .mail folder contains a bunch of files I can't identify what they are or what they are used for. I have moved ALL THE FILES AND TOKENS to a temp directory and my Here seems to be working fine with the .mail folder empty. I think these files have something to do with email I receive and delete. Has anyone ever cleared out this directory to conserve storage space? Are these useless files and can be deleted?
View 7 Replies View RelatedAt 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 have an app that instructed me to copy some data from my computer to the SDCard. So I plugged the Droid into the computer, mounted my Droid SDCard, looked at the directory, and copied the file. There are a bunch of files and folders listed (e.g. backups for apps, album artwork, etc.) as being on the SDCard. But when I go into Astro on the Droid and select "SDCARD" it shows "directory is empty." I don't get it. Why can't I see the folders and files on the SDCard that I can see on the computer screen?

View 3 Replies View RelatedIs there an Android App directory that's commonly used when discussing, talking about, listing, evaluating Apps in this thread? Or, is there an official Android Market listing of Apps? Or another question, is the "Android Market" available the web? I've been to Android Market, but it doesn't seem to list all apps or have a search at this time; only the top paid and top free. When mentioning an App on this forum, it's be nice to hyperlink the standard market listing if there is such a standard or recommended site from this forum for consistency. For now, I'm just mentioning the name of the App - in bold font - as spelled so others can search it in the Android Market.
