I have an android app that stores data to the local storage. This is done just like in the tutorial on Google's site:
CODE:......................
However, whenever the device is powered off, then powered back on, these files are removed. How can I get them to stay?

From the Android documentation:
"You can store files directly on the mobile device or on a removable storage medium. By default, other applications cannot access these files. "
I could write to the sdcard (/sdcard/file.tmp) and other apps could access these files, right?
I would like some local storage that I can write files to (and read from later) that are not accessible to other applications, and I will always have access to. The problem with the sdcard is that if someone plugs in a USB cable and turns on MSC, my application (and all applications on the phone) will lose (both read and write) access to the /sdcard directory. So I need something more reliable.
I published an application that stores data in a local database.
Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.
I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?
If so, how can I avoid this in my code?
I have about 30 DiskCacheIndex files in my root directory of my SD Card. Is it OK to delete them.

The following code works great:
CODE:................
The only problem I have with this is that I don't need to re download these KML files every time. I have about 10-15 KML files that will rarely change. Also since it has to connect, download, and parse these each time there is a delay in opening the maps.
It would make a lot more since for me to save these as a local resource and have the URI reference it there. Is there a way to construct a URI using the geo: scheme and have it point towards a local resource?
It looks like file:///sdcard support was included in 2.1. The only reference I could find to it was at the end of this bug report thread. I am currently at work and don't have time to play with this yet but I would like to figure it out later. I feel like there are a lot of people on stackoverflow and elsewhere who would really appreciate a reasonable way to do this.

I understand how to check if it's the initial start or not, and also how to use java.util.zip once I get the file, but it's the in-between where I'm lost.
View 1 Replies View RelatedThis should be so simple, but apparently, it's not. I have a folder on my Nexus 4 internal storage:
/sdcard/Music/Favorite Songs/Current
... with a bunch of MP3s in it with ID3 v2.4 tagging. How in the world do I add these to the Play Music app (not cloud) without using some desktop manager? I also tried installing Omich Player (a fork of Apollo) and while I can browse to the folder, none of my music shows up under artists/albums/etc.
Due to my little knowledge in Java programming, I've wondered if I'm able to display local html files in my application? (And when yes could you please give me a reference.)

How can I transfer files on my SD card to my phone storage?
View 2 Replies View RelatedI have created a directory and even a file in that directory on the external storage, I am able to read and write into that but the problem is they are not visible on the emulator i.e, in the phone.
View 17 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.
A question about the internal storage that's private to each application (especially when storing files with Context.MODE_PRIVATE).
How is that storage actually assigned to the application? Just by package name or also somehow bound to the sign key of the app?
Let's say I have installed application 1 and then write another application 2 with the same name and package name (just differently signed with different keys) and install it (app 2 replacing app 1), would that application 2 get access to the /data/data/[app]/files ?
Or would I not even be able to replace app1 with app2 due to different sign keys in the first place?
I downloaded a file with an app and stored it inside of its internal storage, but the file is set with -rw- and I want to change those permissions so is it possible? I know that using external storage is an option but I want to know if I can do it with internal storage too. If it turns out that I can't change the permission is there some shared region of internal storage that I could use? I would like to not force the Android device user to have an SD card.

View 3 Replies View RelatedMy application writes data to a file in the SD card directly. There are no errors during the write. But, the file never shows up on the card, in the file browser (on the device - I use Glance). Where did the file go? When trying to browse the device from my desktop, I notice the USB Mass Storage option is missing guess that's expected since others in the forum explain that it was removed in this version. But, I can't get my PC to browse the memory card when it's stored in the phone. This all just seems to add up to a flaky memory management problem, but I can't be sure.
