Android :: Convert JSON Array To Array

Jul 27, 2010

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.

Android :: JSON Array Iteration In Java

Aug 4, 2010

I am building an android app that needs to download and synchronise with an online database, I am sending my query from the app to a php page which returns the relevant rows from a database in JSON format.

Tell me the best way to iterate through a JSON array?

I receive an array of objects:

[{json object},{json object},{json object}]

What is the simplest piece of code I could use to access the JSONObjects in the array?

Now that I think of it the method I used to iterate the loop was:


So I guess I had was somehow able to turn the returned Json into and iterable array. Any Ideas how I could achieve this?

I apologise for my vaguness but I had this working from an example I found on the web and have since been unable to find it.

Android :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array

Jan 12, 2010

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?

Android :: Converting Short Array To Byte Array

Feb 16, 2010

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?

Android :: Navigating An Array - String Array

Oct 12, 2010

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.


But Like I said, I would like to just order through them one by one when a button is clicked.

Apr 16, 2010

I have a collection of strings and declared the strings individually as arrays using ArrayList<String> al=new ArrayList<String>(); and called the arrays in the program by using al=getIntent().getStringArrayListExtra("titles");

Now, instead of declaring each of the arrays i have created like below...

public class SongsArray {
private String title;
private String movieName;
private String singerName;
private String imagePath;
private String mediaPath;

public String gettitle()
return title;
public void settitle(String title) {.................

Android :: String-array Max Size?

May 12, 2010

I have a string-array in my resource file that has a little over 1,000 items in it. When I go to launch the activity that calls an AutoCompleteTextView the app won't load this array it simply backs out of that activity and returns to the previous activity. If I delete a bunch of items in the array it begins to work. How can I make it hold all my items? Is there a max size associated with this?

Android :: Passing An Array To A View

Apr 8, 2010

My background is in C, but I'm relatively new to Java and to Android. I have a question as to whether I'm implementing code in the best way:

As a learning exercise in Java and in meeting the Model-View- Controller pattern, I wrote a simple game. It plays out on a 2D grid owned by the game class, and is drawn to the display by an extended View class. I have it working, but I'm wondering after the fact if I'm going about it the right way.

Here's a simplified version of what I have:

Android :: Parcelable String Array

What would be the cleanest way to make it Parceleable? Apparently String itself is not parcelable, so Parcel.writeList(ids) is not working.I was thinking to either parcelize ArrayList<Uri> or put array contents into a Bundle.
