I want to store a few values in the form of high scores. But since im not going to be storing more than 5 values, using SQLlite doesn't seem appropriate. Another option considering was a flat file, but not sure how to go about..

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".
I am developing an app on Android that will randomly pick and display an inspirational quotation (or verse) from a large collection of quotations. On Android I can choose between a flat file and an SQLite database. The app should satisfy the following conditions:
Be scalable to 10^6 quotations and/or verses
Be very fast (i.e. retrieve and display a quotation, immediately at the touch of a button)
Be able to load new quotations from an external source (in a format I have not yet decided)
What data format must I use?
The question is in the title.

View 2 Replies View RelatedI'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.

View 2 Replies View RelatedI need to store data to use in my android program. Here are the details about the data: There will be one table. Each "row" of data will have a unique INT identifier. Other then that field, there will be four other INT fields and a text field. The string field will probably be a 2 or 3 sentences long. Each of the 4 INT fields will correspond to the ID of other rows.
View 2 Replies View RelatedIn Android when you upgrade a database all data is lost. I'm going through a phase of development right now that is forcing many database upgrades. I don't want to lose all my data (and have to manually re-enter it) each time I upgrade my database. I would like to store my data in flat files and load those flat files into their respective tables each time a database upgrade occurs.
My questions is: What is the best way to go about this on the Android platform? Where should I store the data files (res/raw???) What sql should I execute to load these files?
I'm trying to store a raw uncompressed file into the apk. I already tried rename it to mp3, png, zip, but all these extensions still compress the file: if i open the apk using winzip, it shows tcfiles.png 4194304 -> 4080. I already heard about the "aapt -0" to store uncompressed, but no one tells how to do this from within eclipse. I don't call aapt by hand, i use the one generated by eclipse.

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?

View 3 Replies View RelatedI'm coming from an iPhone 3G, and I have Shure SE115 earbuds. I don't find the audio quality of the Evo to be anywhere near the quality of my iPhone. I don't find the audio quality of my iPhone to be as good as my gf's zune hd. If I put the same song on both my iPhone and Evo, it is immediately apparent to me which one is which. The Evo doesn't go as loud, and it just sounds a lot more flat, and way less crisp. We're talking night and day here, at least IMO.
I don't consider myself an audiophile by any means, but this feels like a huge downgrade to me. I've tried using both the stock music player as well as Doubletwist. It's so sounding. I think I'm probably going to return it, and go with a new iPhone. Anyone else generally unimpressed by the audio quality of the Evo? I'd imagine my beef is with the hardware, and it's pretty unlikely that a 2.2 root would fix my problems.
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 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?
