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 :: Draw Arabic Text After Reading From File?

Sep 26, 2010

I've figured out how to draw Arabic characters properly (connected and right to left) using string literals like this:

textView.setTypeFace(Typeface.createFromAssets(getAssets(),"DejaVuSans.ttf"));
textView.setText("uFEB3uFE92uFE98uFE94");

But for some reason I cannot get the arabic to format properly if I read anything from a file using InputStreams like this:.....................

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

My code is pretty standard.. sReport contains the text I would like output to the text file, and it contains several" "line breaks that render fine in a textview, but in the text file they're non-existent. There must be something easy i'm missing..

FileOutputStream fOut = new FileOutputStream(sDir + sFile);

fOut.write( sReport.getBytes() );
// Close output stream
fOut.flush();
fOut.close();

Android :: Eclipse Reading Code As Java

Nov 23, 2010

I just inherited a project at my workplace and I am having trouble having Eclipse act as an Adroid editor rather than a Java editor. Pretty much everything is under lined and I can't seem to find a way to change how it is interpreted. I have downloaded all of the Android SDK's and the Eclipse Plugin. I can create Android projects and write the code just fine, but everything is still underlining. I must be missing something simple. Any suggestions, something I missed or didn't download?

Android :: Reading Java Serialized Object That Has Been Split Across Two Files?

Mar 2, 2010

I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.

However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?

For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?

Android :: Get Line Number An Xml Element Is On Via Java W3c Dom Api?

Apr 30, 2010

Is there a way to lookup the line number that a given element is at in an xml file via the w3c dom api?

My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception.

Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.

Android :: Reading And Writing To File In Internal Storage

Jun 27, 2010

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.

float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();

That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):

balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

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 :: Drawable Changes Sizes On Screen When Reading Image From File / Avoid This?

Apr 15, 2010

I have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.

On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.

Of course it has something to do with the density but not sure how should I resolve this.

This is my code...

if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.

Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.
