XML database for Android apps - Android Apps and Games

Did anyone used before a local XML file as a database for a android app?
I am trying to build a app with flash using a xml file as database, to read the xml from a external file from the local directory isn't a problem, the problem is how to write data from flash to the xml file.
If used or know some tutorials guides that can help me please leave a reply.
Thank you!

XML files corrupted after backup

I'm trying to backup .apk files to my sdcard via AppManager and then open up the XML files to see if I can tweak it, however whenever I try to do this, with any .apk file, it's always messed up and no matter what program I use to edit the .xml file it won't display and it comes up with errors.
Anyone know why this is and/or how to fix it?

They are a strange mix of binary and hex. It's not a human readable xml.
So is there any way to edit them?

Seems like there is a program that will read and convert them to human readable, but you can't edit them and have the changes saved. I will post back when I find it.
The java program is called AXMLPrinter2 and can be run from a command prompt, which converts to TXT.
I'll refer to Stericson's post here on editing Android XML files

Find cached files?

Hey
So i just got the Blizzard Authenticator from the Android Market, i know it's storing an xml file that has a token and some other information, i was wondering if there is any way i can find out where that file might be?
I want to find the file, because in that way i can sync the key between my computer and phone
Cheers
-Jazerix
It would most likely be in /data/data/package name/shared_prefs, where package name is the name of the apk (probably something like com.blizzard.authenticator).
Thanks for your reply, but when i check out the data folder, it's completetly empty
Is there any other way i can trace the file path?
P.S. i'm using a Nexus S with CyanogenMod
Edit: I'm able to find something on the SD Card (/sdcard/Android/data), but there is no file regarding the mobile authenticator
Ok, so i just bought Root Explorer, and the folder is no longer empty cheers, found the files ^^

In addition to apktool (thanks, @kaiodduarte), you're also going to need a good text editor (I use Notepad++), an archive manager (like 7zip or WinRAR), and the ZipSigner app for your device.

[Q] Problem Modding APK

Hello guys,
I am modding an apk to bypass an update check.
I have this outdated APK that functions fine since the URL and query and site address remains same but whenever it checks for and update it crashes. The thing is the developer made it topnotch but since then left and his site was recently taken down so check update query crashes it totally. What I need to do is update just the one function where it brings up the GUI after start. Otherwise it keeps saying download update or crashes randomly at time of starting up.
Now I have been browsing for a day or two for all the tutorials and right now I`m hell lot of confused. I have downloaded many tools and dependencies but I dont know how to proceed. I will tell you guys what I have and what I need.
I have de-compiled the APK using "dex2jar", I had a .JAR file which I decomplied using JD-GUI-Windows now after saving source I have .ZIP file in which I made the necessary editing. Next I downlaoded APKTool.JAR and extracted resource files and XML files that can be read in text editor. Along with some .SMALI files.
Now I am not familier with SMALI language at all and editing in it seems rather complicated and on the other side I have the .JAR file that decomlied all the classes just fine.
MY QUESTION IS:
How do I recompile the files I have ? I have the main coding extraced using dex2jar so in java format and JD-Gui to in .ZIP files, and resources/XML files also decoded using APKTools. What do I do next to recompile the APK ?
In short I have plain text based java source code and plain text XML and other resource file. How do I recompile it ?
