Android :: Compressed Array Bytes Java From .NET Webservice
Nov 24, 2010
I have a problem.
1 - From a webservice. NET 2008 (vb), I have a method that returns an array of bytes, the byte array is actually a string "Hola Mundo" ("Hello World" in English) compressed with the Class of System.IO.Compression GZipStream.
2 - The method returns the string "Hola Mundo" compressed, and this is what the webservice returns:
CODE:..............
3 - if I do a test from a windows application from Visual Basic. NET to run this method returns me this string and Unzip with another function I have, it brings me the "Hola Mundo" ....
4 - On Android (Eclipse) and I managed to make the request and bring me the previous string ... but do not know how to decompress and show me "Hola Mundo" ...
5 - I have tried several codes from the web, but none work.

I have a frame of 22 bytes. The frame is the input stream from an accelerometer via bluetooth. The acceleromter readings are a 16 bit number split over two bytes.
When i try to merge the bytes with buffer[1] + buffer[2], rather than adding the bytes, it just puts the results side by side. so 1+2 = 12.
How to combine these two bytes to obtain the original number. (btw the bytes are sent little endian)

An Android app I'm writing involves quite a lot of downloading of content (think podcatcher/RSS).
I would like to be able to give the user an indication of how many bytes they've downloaded, so they can make the decision whether they want to use Wifi or not.
To this end, I have found a way of counting the number of bytes read by the app, by wrapping an InputStream in a simple CountingInputStream.
However, this does not take into consideration basic things like packet headers and HTTP headers. More importantly, it does not take into consideration any compression that content may be encoded with.
So, how many bytes did my application download over the network? I'm not so interested in the number of bytes uploaded, but if know how, don't be shy.
I have gone down a fairly low level approach as I am feeding the input stream into an XML PullParser. I will also be needing to do a similar exercise with dumping bytes (images in this case) straight onto the SD Card.

I would like to create a Java-written RESTFul Web Service, possibly using an eclipse plugin.
This service should be consumed by an android application, using the apache HttpClient.
But my question is, which is the best/ideal technology (server side) to implement this kind of web service?

I am a beginner programmer and I am attempting to use the android NDK.
Is there a way to return an array (in my case an int[]) created in JNI to java? If so, please provide a quick example of the JNI function that would do this.

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:
CODE:.............
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.

I'm a little new too java programming. Im looking for a means to store groups of static data..so I understand these simple string arrays...
[HIGH]
private static String[] names = new String[] {
"aidanmack",
"johnsmith"
[code]....
But can I not combine that into an array of objects? somthing along the lines of what you would do with json? like...
[HIGH]
private static array[] multi = new array(){
{"name":"AIDANMACK","age":"30"},
{"name":"johnsmith","age":"31"}
}
[/HIGH]

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 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?

Is it just me or does anybody else notice as well that the images uploaded to ones Android Market's publishing site are heavily compressed. When I look at them after they're uploaded, i can clearly see ugly JPEG-compression artifacts.Is there a way to make sure that the quality of the images stored on Android Market's servers is better?

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.

I am using the AudioRecord class to analize raw pcm bytes as it comes in the mic.
So thats working nicely. Now i need convert the pcm bytes into decibel.
I have a formula that takes sound presure in Pa into db. db = 20 * log10(Pa/ref Pa)
So the question is the bytes i am getting from audiorecorder from the buffer what is it is it amplitude pascal sound pressure or what.
I tried to putting the value into te formula but it comes back with very hight db so i do not think its right

I'm developing an android video uploading app and uploading large amounts of video is a problem, I get different type of exception sometimes (host not resolved, pipe broken), I do a multipart POST but I have a feeling if I upload chunk of bytes one at at time that'll increase upload speed as well as solve connection timeout and these type of problems.

I've tried recording video using MediaRecorder API but the file that gets saved each time is of 0 bytes.
I use the MediaRecorder recorder = new MediaRecorder(); ad then recorder.setVideoSource . . .recorder.prepare() to generate the preview and when the user clicks record, i say recorder.start() but the file recorded is of 0 bytes. And after some time, recorder.stop() -on user click that is.
