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 Store _ Retrieve Vector In Sqlite Database

Sep 1, 2010

I need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?

Android :: Reading Text Or XML File In Android Java

Feb 2, 2010

I am currently working on a group project to build an Android game. I have been delegated the task of building a PC based level editor (which is all done). All I have to do now is decide on the file format for the map that is outputted. At the moment it is just a standard text file with different numbers to represent different tiles; E.G 0=path 1=wall 2=enemy.

1 1 1 1 1 1 1 1
1 0 0 0 2 0 0 1
1 1 1 1 1 1 1 1

The actual Android game then takes this file and stores the values into a 2D Array. However those who are making the actual game are having difficulty opening a text file, and others have told me it has to be done using an XML file. I have now been asked to find a away to take in this input. how I would read the text file and put the values into a int array[][] ? Or if it is easier, use an XML file and tell me how to format that file and read the values into a int array[][]

Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File

Apr 17, 2010

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?

As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

Android :: Way To Store XML Data In A Java Object From A SAX Parser

Jun 21, 2010

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?

Can any of you retrieve deleted text messages or know how? I know you can retrieve them via SIM card, but there isn't one... I have a memory card reader, but if i'm right, you can only retrieve photos from the SD card? I was wondering since most of you probably know how to code that if you knew how to retrieve them a different way or could where to go or how to do it? It would be very much appreciated.

Motorola Droid X :: Way To Retrieve Text Messages?

Aug 30, 2010

I sold my htc Imago with the expectation that the guy I was buying a Droid X from would not super flake on me. Say Craig list! Anyway, I've been without a working device for a week now as I wait for my DX to arrive. I just check voice mail a couple times a day to make sure I'm not missing anything important. On the other hand, I have to imagine I have a serious back log of texts. A buddy of mine said he thought the DX (which my wife currently has) could be configured to retrieve texts from more than one account (phone number). Is that possible? Is there any other way to retrieve text messages other than with an activated device?

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.

For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}


9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Android : How To Store Raw File Uncompressed

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 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?

Android :: Magic Behind R Java File

Jan 12, 2010

I have been having quite some problems with R.java file. Now I have decided to do a backup and delete the file to see what happens. Nothing happened, so I created an empty R.java file and hopped for the best. Now Eclipse seems to figure out that the file was tempered with and even issues a warning: R.java was modified manually! Reverting to generated version. And that's all there is. I tried building it manually but got no results. So, I have two questions: 1. what should I do to force Eclipse to generate the file. 2. what is happening here? How is the file created, where is the code that is generating the file? I would appreciate any help.

Android :: Installing Apk File In Java

Mar 3, 2009

I'm trying to write a java program that will install an apk file on android. I saw that there is an Intent action: ACTION_PACKAGE _ INSTALL, available and the developer reference says: "Broadcast Action: Trigger the download and eventual installation of a package" So I wrote a program like so:

Intent newintent = new Intent(Intent.ACTION_PACKAGE_INSTALL); File apkFile = new File("/data/data/HelloAndroid.apk"); newintent.setData(Uri.fromFile(apkFile)); sendBroadcast(newintent);

But this fails to do the intended task (which is download and install the application). I'm not able to figure what is happening to this broadcast intent, no logs get printed in LogCat. Any pointers on where to look or how to proceed?
