I have a thread which is continuously running ,when i will send the command to get the data, data starts to come. I wanna to show this process to the Asynctask show that user can understand data is reading . How can i achieve this please help me . For now i am using timer. but timer will work for fixed time. but if my data is less, that time, timer will take the same time that i don't want . If anyone have any idea please let me know.... Thanks in advance for help
I had use this but because of running thread message getting continuously.

I am using an android phone to read and write some data to the EEPROM of a NT3H2111 nfc chip.
The method to change sector appears to be working, but never the less, the sector is not changed when i try to read the contents, it is still on sector zero.

I get this result, but from the data i can see that the sector is still zero, and have not been changed to sector one.
D/Ve95_DataModelHandler: Reading section names
D/: sectorSelect caught exception, but succeeded anyway
D/Ve95_DataModelHandler: sectorSelect returned true
D/Ve95_DataModelHandler: 04,B2,87,CA,D4,64,80,00,44,00,00,00,00....
Anyone know how to change the sector?

Have solved it myself. A 1K chip was mounted instead of a 2K chip. No wonder it didn't work :)
I'm trying to write a code I can write all the results values from accelerometer sensor into a .txt file. I can't write all the data in somehow. I think there is a problem in my loop. It is just reading about 10 to 15 samples.
How can I write all the values of the sensor into that file until I toggle off the button to stop? here is the code I wrote.

Could you try this for the toggle button onClick callback? It should write all the data when it's unchecked.
OnStore.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {

// should do nothing
} else if (!OnStore.isChecked()){
try {
for(double TotalAccelerate : list){
//System.out.println("final"+ TotalAccelerate);

byte[] convert = space.getBytes();
fileOutputStream.write(convert);
String finalData;
finalData = String.valueOf(TotalAccelerate);
fileOutputStream.write(finalData.getBytes());
Log.i(DEBUG, "ans: " + finalData);
}
fileOutputStream.flush();
fileOutputStream.close();
Toast.makeText(getApplicationContext(), "Message saving", Toast.LENGTH_LONG).show();

To regulate the code to start/stop listen to the sensor event, add the following variable somewhere in this class:
private boolean isListening = false;
And make the following modifications to your existing code:
OnStore.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
if (OnStore.isChecked()){
//
// set listening flag to true
//
isListening = true;
} else if (!OnStore.isChecked()){

//
isListening = false;
try {
for(double TotalAccelerate : list){
//System.out.println("final"+ TotalAccelerate);
String space = "\n";
byte[] convert = space.getBytes();
fileOutputStream.write(convert);
String finalData;
finalData = String.valueOf(TotalAccelerate);
fileOutputStream.write(finalData.getBytes());
Log.i(DEBUG, "ans: " + finalData);
}
fileOutputStream.flush();
fileOutputStream.close();
Toast.makeText(getApplicationContext(), "Message saving", Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(),"Message Stopped.",Toast.LENGTH_LONG).show();
}
}
});
#Override

if (isListening) {
double xx = event.values[0];
double yy = event.values[1];
double zz = event.values[2];
TotalAccelerate = Math.round(Math.sqrt(Math.pow(xx, 2)

For additional information on usb and connecting you might find the following article helpfull.
http://android.serverbox.ch/?p=549
The last paragraph explains some of the issue you might face. The example they provide may also show you how to go about reading the data and how you will have to format the messages.
It looks like you face two issue. One setting up your code to read message, which Puspendu's answer aludes to, and the second issue which is "how" to communicate, what messages you will need to send to establish a connection, handshake, and determine the good stuff, i.e. the data you want.
Puspendu has shown one example of reading and writing to a device. However i would imagine that depending on the device you connect, the handshake and message structure will change, hence you'll have to look those parts up (afraid i dont know of any other examples).
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

any answer i will appreciate it,
also
what this statement suppose be to do ?
Cursor mmsCur = contentResolver.query(uriMMSURI, null, "msg_box = 4 or msg_box = 1", null,"_id");
I think your approach isn't even the right one.
Afaik you have to register a broadcastreceiver and handle/implement this in your app in order to achieve what you want.
See
Android MMS Broadcast receiver
Detecting new MMS (Android 2.1)
Detecting MMS messages on Android
There are all infos u need ;)
