My application creates directory on SD card for syncronisation purpose. Tell me please, is there any way to delete this directory on uninstall? May be I could add some string to Manifest or catch "uninstall" event or something else?

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 have an app that create a directory and contact files in this. I do not want version update to delete this directory but I realize it has been deleted during the update. How do I prevent this from happening?

View 1 Replies View RelatedI created an application which creates and stores files to sdcard. Is there a way to bind the folder with application in order to delete all files when the user runs uninstall on android device?
View 2 Replies View RelatedIt'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.
I don't know how this app called telmap navigator got onto my phone, only noticed it after I installed laucher. It's even in a different language, it doesn't come up in the list for uninstalling or managing applications and when I use astro to track it down to the system>apps and try to delete it that way it says error.
Anyone know any other methods?
I am trying to have my app create a directory on the root of the SD Card, if that directory does not already exist. When I run the app, the "Creating Home Directory..." toast notification displays, but the directory is not created... What am i doing wrong?? (P.S. permissions are set for writing to external storage)

Here is my Manifest file:

I tried this as well, it didn't work, but it might be a step in the right direction as it creates the directory and populates it with a file from res/raw all in one step:

I am having trouble removing apps. I go to "All apps", touch and hold on the app I want to delete until the front page comes up with the trash can saying remove. I drag it over top of it and let go. But then I go check, and it still shows up on the "All apps" page. What am I missing/doing wrong?

How to create a directory and sub-directory via code.
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 1 Replies View RelatedI've got an app that is heavily based on remote images. They are usually displayed alongside some data in a ListView. A lot of these images are new, and a lot of the old ones will never be seen again.
I'm currently storing all of these images on the SD card in a custom cache directory (ala evancharlton's magnatune app).
I noticed that after about 10 days, the directory totals ~30MB. This is quite a bit more than I expected, and it leads me to believe that I need to come up with a good solution for cleaning out old files... and I just can't think of a great one. Maybe you can help. These are the ideas that I've had:
Delete old files. When the app starts, start a background thread, and delete all files older than X days. This seems to pose a problem, though, in that, if the user actively uses the app, this could make the device sluggish if there are hundreds of files to delete. After creating the files on the SD card, call new
File("/path/to/file").deleteOnExit(); This will cause all files to be deleted when the VM exits (I don't even know if this method works on Android). This is acceptable, because, even though the files need to be cached for the session, they don't need to be cached for the next session. It seems like this will also slow the device down if there are a lot of files to be deleted when the VM exits. Delete old files, up to a max number of files. Same as #1, but only delete N number of files at a time. I don't really like this idea, and if the user was very active, it may never be able to catch up and keep the cache directory clean.
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.

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?

But I hate the gmail app on the wildfire running android, and really like the mail app.
Problem is, Gmail is currently syncd to both and so if Im not at the phone when I recieve a message notification I will recieve two notifications for the same message (one from gmail, one from mail), and then can view it in both apps. in a nutshell, I want to be synced to gmail, using the mail app, and I need to know how to turn off the gmail app, without losing any syncing etc.

View 7 Replies View RelatedSo for the past year I have been using a blackberry bold 9700. At the time when I bought the phone, AT&T didn't have any really appealing android offers. Anyway, the captivate came out, and it seemed like finally there was a good, high end android phone for my carrier, despite AT&T's usual bloatware BS. So I went onto craigslist and found some dude who was willing to sell his captivate for 200 bucks + my bold 9700 (side question, was that an OK deal? I feel like a little less money would have been fair).So we met traded, I'm finally on android, I love the phone, but there is one problem.There is an application on the phone called superuser permissions that I can't delete.I found out it's a program used for rooting.Even though I plan to root my phone eventually, I don't want to root it yet (I'll wait until froyo is released for my phone), and I would rather just root it myself and know what I did to my phone, if that makes any sense.
To make matters a little trickier, I use a mac. I can transfer files between my phone and my computer by going into usb debugging, but the samsung only has drivers that work with Windows... I don't know if that's a problem or not but I just thought I'd mention it.
I don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):
CODE:.........
The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.
In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.
I need to delete Google Play Service completely from my phone or totally disable it!

View 1 Replies View RelatedI have a large directory (about 700 MByte) I'm trying to push to a 4 GByte emulated SD card (in a Platform 2.1 AVD) by dragging and dropping the directory onto the ddms file explorer's /sdcard directory, but ddms is timing out after about 20 MByte of pushing. The following command line error message appears:
34:05 E/ddms: ADB rejected shell command (ls -l /) Failed to push the items: timeout
When ddms is connected to an actual device (Nexus One), the same drag and drop operation successfully completes.
I looked but didn't see any mention of timeout control options in the ddms documentation at http://developer.android.com/intl/de/guide/developing/tools/ddms.html or the Dev Tools application running on the emulator. Has anyone experienced this or have a tip to fix it?
Are there specific directories that should be setup for Android to understand what is in them? Like a "MP3" directory for music or "images" for photos etc.?

View 1 Replies View RelatedI 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?
