I have this problem. Two apps: app_a and service_s. Service_S creates file in /tmp. After create this file, service_s uses FileUtils.setPermission to change file mode to 666. Then app_a tries to delete this file. But I always failed when deleting. It seems the files are private. One application cannot delete files which another application creates. Is there any way to delete this file?

View 5 Replies View RelatedIn one android application, I created a database file in data/data/com.rams/databases/dbfilename.
If I created a second application with the same package name (com.rams) and I access the database file created with my first application, the second application is able to access the database contents.
How can I secure the database file created with my first application?
I'm developing for the Android platform.
My app creates a temp file with a simple call to:
FileOutputStream fos = openFileOutput("MY_TEMP.TXT",Mode);
It works fine because I can write to it and read it normally.
The problem is that when I exit from the app I want to delete this file. I used:
File f = new File(System.getProperty("user.dir"),"MY_TEMP.TXT");
f.delete()
But it always returns false and the file is not deleted.
I have tried
File f = new File("MY_TEMP.TXT");
f.delete();
And it does not work either.
I am trying to follow the instructions on this page to create a trace file. I can see the file in File Explorer in DDMS and can pull it onto my PC but it is zero bytes long.

I'm trying to do my first ROM install and am following these instructions which no one seems to be complaining about: FAQ - Cognition Wiki
Seemed pretty straightforward, but isn't working because I have no update.zip created by ROM Manager. When I did the "Flash ClockworkMod Recovery" step no update.zip file was created in the internal SD root. Buried in the clockwork mod folder is recovery-clockwork-2.5.1.2-captivate.zip, do I move this and rename it?
Just made an update.zip using Titanium Backup 3.4.1. Can anybody help me with how to sign it as it is unsigned. I am sure an unsigned update.zip can't be installed from the recovery menu.

View 3 Replies View RelatedI have used the android internal storage to save a file for my application (using openFileOutput) but I would like to delete that file, is it possible and how?
thanks maxsap.
I have a rooted desire, but I have a troublesome app that won't update and I can't delete. I have seen others who have had the same problem, and a solution is to rename the app .apk.old and then redownload it, but I can't find a decent app to do this. I do have superuser permissions.
View 2 Replies View RelatedWe are starting the e-mail intent of the user's choice (createChooser) and sending a zip file. This zip file is created right before the email sends, but we need to make sure the file is there until the email actually gets sent. Once the e-mail is sent, it would be nice to have this file deleted instead of sitting around eating SD card storage. Is this possible? (it can't be done in onActivityResult, e-mail intents don't actually finish, they cancel and thread the sending in a background service...so when onActivityResult gets called the e-mail might not have sent yet). Any ideas?
View 1 Replies View RelatedWhat i want to do: delete an image file from the private internal storage in my app. I save images in internal storage so they are deleted on app uninstall.
I have successfully created and saved: code...
I have read on the android developer website that i must open private internal files using the openFileInput(...) method which returns an InputStream allowing me to read the contents, which i don't really care about - i just want to delete it.
can anyone point me in the right direction for deleting a file which is stored in internal storage?
I can create a new preferences file by calling Context.getSharedPreferences(String name, int mode), putting some values in the returned preferences' editor, and committing. However, I don't see an interface in the API to remove the created file when I no longer need it. I've tried Context.deleteFile(String name), passing in the same name argument from above, but that returns false, indicating the file wasn't actually deleted. I'm using MODE_PRIVATE, if that makes a difference. Browsing the source for context's implementation of the editor doesn't reveal any clues either, as far as I can tell. Any ideas? The background here is that I'm allowing my users to save copies of their "current" preferences so that they can restore previously saved settings. When they don't want those settings anymore, I want to remove the saved preferences file so it doesn't take up space. At the moment the best I can do is an edit().clear().commit on the file, which I believe will remove most of the contents. Not as good as delete, though.

View 1 Replies View RelatedI have a Nexus7 (8gb) with a file headed "WV" and titled with a list of numbers in the "Personal Videos" file that does not appear on my desktop when I connect the Nexus. I now have four films (excluding the stray file) that I want to keep on the Nexus which are all under 1gb each, however my Nexus is now saying that I don't have enough memory to even download basic apps. I think this stray file may be to blame as I've checked the folder sizes using my desktop and I'm well within the 8gb capacity limit.The Nexus will not play the stray WV file; I get an error message saying "file cannot be played".
