Android : Can I Store Data In APK After Creating It?
Feb 4, 2009
This issue has troubled me a lot, please help if you have any ideas.
- I am accessing an xml file from withing the apk, (stored in /res/ raw). The xml is read succesfully. My goal is to use this xml file as data that can be changed in the apk.
- I tried unpacking and packing the apk file with ZIP compression and the newly packed apk worked on the phone.
- I changed the xml file and packed the contents of the apk into a new apk
- "install was unsuccesful" was the result of installing the new apk
As I see it, for every file stored into the apk, there are equivalent references stored in the manifest and cert files:
for example: SHA1-Digest: YS8iSCii71WMNrK7CHy5XLXBo+k=
Do you have any other ideas of how I can store/alter information into the APK?

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.

The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which
is loaded with Resources.openRawResource(id).
It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This
my code to do this : Code...
The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentuated characters appears well.
But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions?

I've created some ring tones and want to transfer them to my phone. I see that I need to create a folder and I don't know how to that. I'll assign them to people in my contacts from there.

I am writing an application that needs to store keys that will be compared against later. How can I do this securely? I have looked into using a SQLite database, but this doesn't seem to be secure at all...any thoughts?

I'm writing an application that needs to store some small jpeg or pngs. Looking at the documentation i have seen that databases are stored under /data/data/package_name/databases I decided to store my data under /data/data/package_name/files. With the emulator i can see all these files (databases and images) under the proposed directories but moving the application on a real device and installing a file system browser i cannot see any file under /data. Can anyone explain me why? My application works perfectly on my mobile (HTC magic) so i think that data is downloaded and stored. If this is a security constraint,do i need to put the application under debug on the mobile in order to inspect file system?

I was wondering how I can create a variable for whether or not my phone has data connectivity. I use google voice for texting (I have a sprint integrated google voice number), but when I go out I turn off my wifi/3g to save battery, and text with my stock SMS app. When I swipe upwards on my launcher (Nova launcher), my texting app launches (google voice). However, I would like that gesture to launch a Tasker task - one that launches Google Voice if my phone has data connectivity, or the stock SMS app if my phone does not have data connectivity. However, Tasker does not have a built in variable for data.
More specifically, I would like this task to do the following (in pseudocode)
if (%data == ON)
Launch Google Voice
else
Launch stock SMS app

For a particular activity - what is the best way to store data that needs to be displayed. The issue is that when the user changes orientation, you need to be able to re-render your activity which means you need to get back at that data that you use to render. I understand the MVC design pattern, but I guess I'm wondering where the M should be stored. Global variables? Static members of your activity? Serialized to private storage?

I'm looking for the best way to allow users to sync their data to their gmail account. The idea is to be able to access the same data via my other applications for computers, phones, etc... I need it to be a free service... The data is a list of items that contains a title tied to a playlist. Anyone know of a particular Google lab allowing such data? Or other cloud services?

Is there a way to store android application data on the SDCard instead of the internal memory? I know how to transfer the application sqlite database from the internal memory to the SDCard, but what if the internal memory gets full in the first place? how does everyone handle this?

I want to store location data in sqlite. A latitude coordinate is a double, with 15 point precision. As far as I can tell this corresponds with the 'REAL' datatype which is 8 bytes. The alternative I suppose would be to store it as a String, and simply convert it back into a double later. Does it make any odds which way I go? Are there differences in storage capacity / efficiency?

I'm getting hung up on how to handle the data for an app I'm designing. I want to pull a list of items from the net. The data is updated routinely, and I think it would be good to store all the data on the device so the app can load quickly and refresh the data in a background thread rather than have to wait for the network on every start-up.
I think I should make the data available in an XML and have a thread parse and save into a SQLite DB, but I'm not sure if that's the "best practice." Are there other ways that people go about handling this?

I am developing an Android application where you should be able to browse restaurants.
Im retrieving the information about the restaurants from a service, they are not stored locally on the device. But I want to allow the user to add a restaurant to his/her favorites.
What is the "best" way to store that kind of info on the device? Should I use Shared Preferences or Sqlite db? Or any other suggestions?

I want to store some additional data for each contact on Android.
I would have in mind creating my own database table for it, and then bind them to the real contact via a unique id.
I am wondering if Android has built in functionality to store additional data against contacts?
EDIT 2
Is there a defined field for birthday of the contact?
How do I store a date field?

In my application, I am going to create a few listviews that are dependent on the listview before it. For example,Then, depending on user choice, will go next screen, let's say, it contains a submenu of each type of school,that may be different or may be the same to other states.What I want to know, is how to populate these different lists dynamically as the user goes on? I don't know what the best of doing this is, and I seem to be looking in the all the wrong places because I keep getting stuck. Once all the data is added into whatever structure is used, it will be static. I basically just need help as to how to code information into some sort of hashtable or anything of the sort that can be easily referenced, and later when the Application is updated, be able to add more schools/states/submenus etc.

I'm writing an application wherein users will sometimes make orders through it. I want to give users the option to save their billing info (name, address, etc.) so that it can be quickly restored later if they want to make another order. The user will enter a password to secure the data. Obviously I can't just put this as a file on the device, as anyone can root/find the data. Is there a built-in Android method for storing secure data that is locked with a password? If not, what is a good place to start for storing this data securely using Java?

I'm developing an Android and web application that will function as a service (use the same data). My question is how should the data be stored to allow for both the web and the android application to have access to the same set of data? Should the android application connect to the sites MySQL server to store/access data? If so how do I allow someone to access the data when they are not in a service area?

My android app fetches a JSON structure from the net. It's somewhat large, maybe 2,000 characters in length. I need to store it away when my app gets killed so I can recover it quickly. I've tried saving it to an sqlite database, but that takes about 400ms, kind of long. I wonder if it's bad practice to just dump it into the save bundle:or are we really only supposed to be putting the smallest of items in bundles?

I have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).
Does this make enough sense without displaying any code?

I would like to store some app-specific data in the contacts db. Is it safe to stuff random things into the Contacts.Settings table? Will it affect the GUI? Does anybody have an example of doing that? It's not really clear to me if there's a proper mechanism for this, or if the settings table is reserved for the systems own use.
BTW my first attempt was to use an app specific database, but then users would uninstall the app, reinstall it later and wonder why it didn't work. My second attempt was to stuff the data into the JPEG headers but the sync process deletes them, presumably for security reasons. So if there's no way to store my things in the contacts db directly, I think I'm out of luck - I'll have to look at steganographically encoding the data into the raw pixels themselves!
