Android :: Is It Efficient To Use Text File Or XML File To Store Static Data

Jul 31, 2009

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".

Android :: Need To Read Trace - Text File /no Data Directory

Sep 25, 2009

Sometimes in LogCat I'll see Wrote stack trace to '/data/anr/traces.txt'

But when using the DDMS perspective, "File Explorer" View, I can't see anything in the "data" directory, I'm assuming because permission denied. Is there a way (short of rooting my ion device) to read what's in that text file?

Is there perhaps an android app for developers that will show the contents of the file? It would seem there would have to be some way of reading the file without rooting the device, otherwise why does the o.s. write it out? How can I read this file?

Create App That Draws A Map Reading Data From Text File?

Oct 12, 2011

I have to create an app that draws a map reading data from a text file : for example the text file can be like

. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3

so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"

next, when i have all the data, draw a simple image rappresenting the data..

my questions are...

there is a function like fscanf?

and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL

Android :: Efficient Way To Store Images

Aug 3, 2010

My application requires that when a snapshot is taken it must store in memory and next time when I restart the phone I must get a thumbnail of that photo in list of photos and the full scale photo when I click on it.There are 2 ways I know.

1. Store images directly. Concern here is every time it has to hit directory to get image which takes some time.

2. Store all images in single xml. Concern here is XML will be too big and takes time to parse.

Android : How To Store Raw File Uncompressed

Feb 11, 2010

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.

Android : Architectural Design / Run Out Of Memory When Store File

Dec 1, 2009

I have an application that requires about 24Meg of mp3 files as a core part of the app. If I store them in the /raw directory on the emulator, I run out of memory. I can store them on the SDcard, but my question is will they be included when I package the application for the marketplace, or do I need to have the user download the files after they have the app on the phone? Where are larger files typically stored in Android apps or are large files not usually included?

Replace Single Row View In Custom STATIC ListView - STATIC Data

Mar 18, 2013

I have Eclipse Juno and I'm working on an app with that.

The main activity will have a scrollable menu that takes you to all the other activities.

So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.

Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)

- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

- Item ??: Centred, bold, non selectable title (Tools)

- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.

I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.

I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.

I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C

I tried deleting both data and cache of both, I uninstalled the old app and also tried downgrading both Play Store App, but nothing worked.

I found that the APK files I receive for paid apps are not standard zip files, they seem corrupted or encrypted: can this be?
