I try to send an image over bluetooth to another device. This works mostly fine, but sometimes, I get a StreamCorruptedException: Wrong format: 0x27 on the receiving device. Anybody knows what this means? And how can I avoid that?

How do I store and retrieve a byte array (image data) to and from a SQLite database in Android?
View 1 Replies View RelatedI 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?

View 3 Replies View RelatedI ask if there is a simple way because there is a google issue report saying that using decodeByteArray isn't possible. But that report originated in 2008 and I was hoping there was a solution not posted on there. The method listed on the issue report was to decode the format yourself, but I'd prefer to not have to put that in and slow down the program.

View 7 Replies View RelatedI'm using the following code to encrypt a String (inText) whose output is a byte array named cipherText;
Code:
byte[] cipherText;
cipherText=cipher.doFinal(inText.getBytes());
The cipherText is printed in a textbox as follows:
Code:
encText.setText(new String(cipherText));
Everything works fine until here. However, in the decryption section, I need to get the contents of the textbox as a byte array again. For this purpose, I use the following code:
Code:
byte[] cText;
cText=encText.getText().toString().getBytes();
When I try to do the encryption it gives a 'bad size' error. I found out that the lenghts of the two byte arrays cipherText and cText aren't equal:
Code:
decText.setText(Integer.toString(cText.length));
encText.setText(Integer.toString(cipherText.length));
boolean res=Arrays.equals(cText, cipherText);
result.setText(Boolean.toString(res));
The 'result' textbox always prints 'false' meaning that the two byte arrays cipherText and cText aren't equal. However I convert cipherText to a String to print in a textbox and then read the contents of that textbox, convert to String back and then to Byte Aray again. Obviously some data is lost during these conversions.
Please could anyone suggest an approach for transferring a >2MB video from a ContentResolver into a Bytestream, without running out of memory?
See question: http://stackoverflow.com/questions/2599305/android-outofmemoryerror-w...
Here's the current code, which throws an OutOfMemoryError on the byteBuffer.write(buffer, 0, len) line when transferring large videos:
// get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString);
public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString);
InputStream is = cR.openInputStream(tempuri);
byte[] b3 = readBytes(is); is.close(); return b3;
}
I'm writing a small program in which I'm using my phone to detect Bluetooth devices. I'm currently stuck on populating an array list with the names of all the device names that have Bluetooth.
Code:
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
for (BluetoothDevice device : pairedDevices)
mArrayAdapter.add(device.getName());

For some reason, the array list isn't populating. Also, how can I display the array list in a ListView
I am trying to establish a server (J2SE) and client (Android). The client will send a string over to the server over Bluetooth.

View 2 Replies View RelatedI'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.
