Android :: Completely Wipe Out The Application Data?
Feb 4, 2009
I'm developing an application which downloads a file from FTP server. The code first checks if file is present on local system . If it is not present on local system then it downloads it from FTP server. Application must download file from FTP server when it executes first time after getting installed.
If we reinstall the application , android preserves the data of old application .So now application finds the file on local system and does not download it from FTP server. But it should always download the file on first execution after fresh install. Is there any way to completely wipe out the previous application data on fresh install? Is there any registry or some location where an application can store data and it gets automatically wiped out when application is uninstalled?

Is there a difference between the CMW wipe data function compared to the about phone => privacy => factory reset option? I'm running android 2.1 on a Fascinate. Thanks for any responses!

I use Exchange Server for accessing email, calendar, etc, on my current iPhone. As a result, if my phone is lost or stolen, I can remotely wipe out all the data if I want to. I am about to replace all of our iPhones with EVO's and would like to know if I can do the same thing with those.

I'm unrooted and just running Launcher Pro Plus. Is there any benefit to wiping phone before getting the 2.2 OTA update? It's really annoying to have to re setup everything you know? Just wondering.

Im going to send my Inc in for a return.. Just curious if its possible to recover any data after I wipe the phone? Does the phone do a secure wipe or is the data still there just waiting to be overwritten?

what exactly does a data reset do? Does reformat (a) partition(s)? If so, which? If not, which files/directories are removed; What exactly IS deleted? Second, how would I do a data reset through ADB?
My screen is basically broken. It works for a split second when first starting up (cold boot), and flickers off and doesn't turn on. Everything else works. I'm planning to resell for parts; I think I've invested way too much for this phone (screen broke before, and then got stolen, and now broken screen again). I would like to erase all data on the phone. I would normally do this through Clockwork recovery, but can't on the account of being blind due to broken screen.
I did come across this thread, but it still left me questions. Is reformatting system necessary? How would reflash my ROM via ADB? What about wiping Dalvik cache? Is dalvik stored within the cache partition?
As for the phone itself:
Samsung Galaxy S Epic 4G (Sprint)
RandomROM Thunkderhawk 3.5
USB Debugging enabled.

I can't completely erase data. Yes I've wiped in cwm installed different ROMs cleared everything restored from RUU but using the app Diskdigger I can always find files & everything that I've already deleted. I have tried force running the TRIM action which was successful but I'm always able to recover deleted files.

My pictures and documents on my SD card are far more important than any text message or calendar entries I have on my phone. Just wondering if there's anyway to remotely wipe the SD card as well.

I am unable to completely destroy my app. My app is thread based app. Once i exit the app by calling on Destroy method, it is exiting properly. If i try to relaunch the application is says "The application stooped unexpectedly, try again". If i again select my app it is launching. It means in a alternative attempt its launching. as i am guessing, its not making Null for few static objects. once it shows the exception has explained above it is making all the objects null, so that i am able to relaunch. Pls can some one suggest how to overcome this issue. How to completely destroy the application?

I'm flashing back to an old ROM. But I just want the exact state that I was in when I made the nandroid backup. In ClockworkMod Recovery, there's an option to wipe all user data. Is this what I should do, or is this a complete wipe of everything, including, say, root access, nand unlock, etc.? If so, what should I do otherwise?

Need to wipe data from the bootloader on DroidX. Stuck in a bootloop with no working vol - button to clear data from recovery. Have tried every sbf out there but none of them wipe data (as they likely shouldn't). Told Verizon my battery went dead during an update and now it just keeps restarting.

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

I'm considering installing a rom and I've heard that doing a data and cache wipe is the proper thing to do to ensure success. What I'm concerned about is how easy it is to restore/re-do all of your settings like ringtones, notification settings, app settings etc. How long does it usually take you to set up your phone again after installing the new rom?

If you do not root, you could go from 2.0.1 to 2.1 with no wiping of data and cache, it just installs & away you go. Same with 2.1 to 2.2. No wiping of data and cache and all is still there as you left it: apps, settings, preferences, etc. SO, why is it important to do this if you root? What's the difference? And, who said it was important to do? Is there some exact proven logic on why if your rooted you must do this and if not, your somehow fine? That 1 step difference causes a lot of extra work, so I am wondering why this is said to be a must for rooters and non rooters need not do it when they get updates?
