Android :: Get Short Array From Resources On Droid?
Apr 10, 2009
I've got an XML file storing an array of shorts in my resources. I need to assign this array, but Android API only provides a way to get array of ints (getResources.getIntArray()). I've ended up getting an array of ints and converting it to array of shorts later, but that's hardly ideal.
Is there a way to get an array of shorts from Android resources? If not, is there a more efficient/cleaner way of converting int array into short array? My code ...

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

I want to have some static numeric and text values as an application resource. For example my data is like this:
Levels 5 First_Level 500 60 1 Second_Level 500 80 1 Third_Level 200 60 1 Fourth_Level 130 30 2 Final_Level 100 30 3... and another 300 lines...
The format and order of the data is predefined and guaranteed to be valid.
I could read it with java.util.Scanner, but it's extremely slow in Android, reading a 10 KB file takes minutes. It's slow because of the regular-expression-based pattern matching inside (when I traceview'ed it).

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.

Is there a simple way to convert a JsonArray to a standard Java Array? Obviously, you can iterate and do it explicitly, but I wanted to see if there was a direct way to do so.

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

Well lately my battery life has been horrid. If I am lucky I get 7-8 hours. That's with little to no internet use and just texting. Like now I'm at 70% and my phones been unplugged for 1 hour and all I have done is text a little and browse Facebook via the app for a little. I'm using BB .4 with the stock kernel. I was gettin better battery life than this before.

I've looked everywhere to get rid of the annoying short vibration that occurs each time you press a number on the phone dialer keypad. I just want the tone. Surely this isn't something that's hardwired?

I have some resources in my app that are going to be loaded optionally for different brands. I don't want to set up entirely different projects each time we re-brand the app so I want to know if the resources that are not used will be always packaged in and if there is a way to avoid this.

So I use my Eris as a GPS from time to time and when I do, I do not want the screen to shut off automatically. I know how to change this in settings but what I want is a widget that I can keep on my home screen that will disable the screen time out, and then turn it back on again (the way the wifi short cut allows me to turn my wifi receiver on and off without going through settings.
I do not think such a short cut already exists, I would happily write it myself, but not sure how to go about starting.

I've got some XML resources in my Android app. Each one has a different name like "bicycle.xml" and "car.xml". I'd like to know if there's a way to load resources based on conditions during run time.
As an example...
Say I had a text input in my app. When the user enters "bicycle", my app can look up an XML resource by that name, parse and load it. Whereas if they enter "car", they would end up with the data from the other XML file.
I've noticed so far that to load resources, you have to use the autogenerated "R" class, which restricts you to hard-coding resources at compile time.

I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?

When I make a call there is a short, odd ring-tone that occurs just after I press Dial and before the normal ringing sound begins to indicate the call is going through.
It's about 1/2 second long, can be quite loud sometimes, and is kind of high-pitched....sorry, it's hard to describe. The tone modulates up and down quite fast - da-dum-da-dum-dum (if you can imagine).
I tried re-programming the phone, and also updating roaming, and it's still there every time I make a call. I haven't made any changes to call settings to speak of...never had this on my D1.

I have an xml resource in res/values/integers.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer-array name="UserBases">
<item>2</item>
<item>8</item>
<item>10</item>
<item>16</item>
</integer-array>
</resources>
and ive tried several things to access it:
int[] bases = R.array.UserBases;
this just returns and int reference to UserBases not the array itself
int[] bases = Resources.getSystem().getIntArray(R.array.UserBases);
and this throws an exception back at me telling me the int reference R.array.UserBases points to nothing
what is the best way to access this array, push it into a nice base-type int[] and then possibly push any modifications back into the xml resource.
I've checked the android documentation but I haven't found anything terribly fruitful.

Received my 2.1 OTA at 1:36 AM last night and ever since, I can't manually lock my phone by short pressing the power button anymore. I thought maybe this was a Spare Parts issue, since I had changed the Power Button behavior on 1.5 using Spare Parts (when I pressed Power from any screen, it would return me Home; pressing from Home would Lock). So, I uninstalled Spare Parts, but this didn't remedy my problem. Any advice?
