Sorry for inconvenience i can't put whole code.
I tried to casting retrieved object with standard code but it's giving me this error so, how can i retrieve Dev object through handler and use it ?

Did you consider using ByteArrayOutputStream instead of FileOutputStream? I have also problem with reading files the other day, which took to much time and I found somewhere in google example with ByteArrayOutputStream and that helps a lot
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] ba = new byte[(int) files[i].length()];
for (int readNum; (readNum = fis.read(ba)) != -1; ) {
bos.write(ba, 0, readNum);

You had the Collections.shuffle() part right, you just need to get the randomized list back into your array:
private Integer[][] img_mc = new Integer [16][2];
...
List<Integer[]> img_mc_list = new ArrayList<Integer[]>();
for (Integer[] img : img_mc) {
img_mc_list.add(img);
}
Collections.shuffle(img_mc_list);
img_mc_list.toArray(img_mc);
Or use this:
private void randomize(Integer[][] array) {
int index;
Integer[] temp;
Random random = new Random();
for (int i = array.length - 1; i > 0; i--) {
index = random.nextInt(i + 1);
temp = array[index];
array[index] = array[i];
array[i] = temp;
}
}
I'm developing an app in which the user inputs his/her voice and the app will calculate its features. so I put a progress dialog to inform the user that the app is calculating its features. At first, the application runs perfectly, then on third run, the progress dialog returns null pointer exception. I don't know how to fix. Here's the logcat:

I think the problem is in actionBt where the function startRecord() get called and in the line progressBar.setProgress(0); if the progressBar didn't yet initialized then Error will raise.its not a good way to initialize a global variable several times in different lines.

this all of my code.
You don't show where you create your handler (onCreate ? onStart ? somewhere else ?). Is it started from the main thread ? If so, you need to be provide a more complete stack trace so we can understand.
If you're starting it from another thread then that's the issue because it's attempting to change progressDialog and that must be done from the main thread.
PS: if you used an AsyncTask you wouldn't have to scratch your head around this as it's designed to do exactly what you want and be thread safe.
Post comment : use an AsyncThread : add the progress bar in onPreExecute(), change run() to doInBackground() and move the dismiss() to onPostExecute(
I am developing an application to receive data on an Android device from an Arduino. It displays values only up to 255 when I convert it to integer, but I want those values which are sent by the Arduino board. I have tried converting them to strings but that didn't work either.

It looks like the problem is in the Arduino sketch. The msg array contains (unsigned) bytes which have a maximum value of 255.
The line:
msg[1] = value/10
implicitly truncates value/10 (which is an integer between 0 and 1023 - see http://arduino.cc/en/Reference/analogRead) to a maximum of 255.
To send value/10 you'll need to split it over 2 bytes. For example:
msg[1] = (uint8_t) (i & 0xFF);
msg[2] = (uint8_t) ((i >> 8) & 0xFF);
And msg will have to be one byte longer to accomodate.
On the Android (Java) side you'll need to do something like:
int value = (int) buffer[0];
// ...
int tds = buffer[1] + (buffer[2] << 8);
m.obj = new ValueMsg('f', value, ret, tds,
buffer[3], buffer[4], buffer[5], buffer[6]);
which will require a change to the definition of ValueMsg to accomodate.
Also, there may be a problem with the calls to SndData (assuming the library being used here is the USB_Host_Shield_2.0) as they always send 6 bytes even though in the first time through loop all 6 bytes of msg won't have been initialized.
