Im trying to convert a byte array which is in Base64 format to String as below. Data was not assigned properly to the String. Do I need to pass the encoding type while creating the new String?

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?

View 4 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.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.
I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
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?
View 1 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 1 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;
}

View 2 Replies View RelatedI have a JSON Object with a latitude and longitude String on which I get the values doing this: String latitude = picInfo.getString("latitude"); String longitude = picInfo.getString("longitude");Then I convert them to floats like this: float latInt = Float.valueOf(latitude).floatValue(); float longInt = Float.valueOf(longitude).floatValue();And place them on a GeoPoint like this: GeoPoint X = new GeoPoint((int) (latInt*1E6),(int) (longInt*1E6) ); Debugging this values I can see JAVA approximates the values, is there anyway to keep them exactly the same?
View 6 Replies View RelatedI'm looking for a way to convert a string to a charsequence.
My code is:
Code:
public void randText(int r){
r++; //necessary increment
String rs = Integer.toString(r); //random string[code]....
The random int r is created outside the method. This method gives a random string, from my resource file. All of the strings have names q1,q2,q3,... There will be 100+ such strings.
This doesnt work at all. the setText(cs) line fails. Is there any way to convert string -> charsequence? Or to have it read as a resource file and not a string?
I have defined a string array in the resource and access it using:
String arrStrings[] = getResources().getStringArray(R.array.arrayname);
But, how can I get the size of this array?
I'm downloading text data from a web server, and getting an Input Stream. The data will be relatively large and delimited. I want to split this data by the deliminator and store each piece in the DB. Is it faster to read the Input Stream byte by byte to split the data and store each piece in the DB, or would it be faster to convert the Input Stream to a String and use an existing function such as Split?
View 2 Replies View RelatedI 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?

ArrayList<String> ids = ArrayList<String>();
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.
