i coud not read total rows some rows is jumbed

i need to debug the below code to trace some unexpected results from the begining of the while loop. i put break point in the line of while loop but the debugger does not reach to it i want the debugger to run all code before that line then stop at the line to be debugged step by step how can i do that

Accoure Error 500 when i use HttpClient of android?

I have below code and in this code i am using from HttpClient for connect to webservice .Net but when i using this, i get Error 500 from here Log.i("OK", Integer.toString(code)); but i need that when i get 200 i login to webSite and etc..
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
HttpClient client = new DefaultHttpClient();
HttpPost methodPost = new HttpPost("http://online.test.com/MobileWebService/Related.asmx/Login");
try {
HttpResponse response = client.execute(methodPost);
int code = response.getStatusLine().getStatusCode();
Log.i("OK", Integer.toString(code));
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
}
Notice 1 : ..../Login is a method in webService for login. It get 4 parameters .
Notice 2 : As the first step i should be sure that it is connected successfully (I mean I should get the "200") and then Login to webSite.
I don't like use KSOAP .
And below is my webService .Net:
[WebMethod(EnableSession = true)]
public int Login(string username, string pass, string device, int? security)
{
var ret = -3;
try
{
var bs = new BaseMaster();
if (!bs.securityRequest(10))
{
return -10;
}
bs.setLogMobileVisit();
if (string.IsNullOrEmpty(pass) || security == null || string.IsNullOrEmpty(username))
{
ret = -2;
}
else if (security != 128110)
{
ret = -1;
}
else
{
var user = GetUserByName(username);
var p = Hash.MD5(pass);
if (user != null && user.Hidden == false && user.Password == Hash.MD5(pass))
{
if (user.Firstname != device)
{
return -4;
}
var u = new UserDB();
u.LastLogDate = DateTime.Now;
u.UpdateDate = DateTime.Now;
u.UserID = user.UserID;
Makarem_Facade.MakaremFL.UpdateMobileUserDB(u);
ret = (int)user.UserID;
var pl = new PermissionDBList();
Security.Login(user,false,pl);
StartSession(user);
}
else if (user.Hidden == true)
{
ret = 0;
}
else if (user == null)

How to create and show Qr Code in Android App [duplicate]

This question already has answers here:
How to generate a QR Code for an Android application? [closed]
(6 answers)
Closed 9 years ago.
can you help me please. I want to write small app for Android that has one button. When you push it it must show you qr code. Qr code must be generated form some string.
Tryed so far:
public void onClick(View v){
QRCodeEncoder qrCodeEncoder = new QRCodeEncoder("Hello",
null,
Contents.Type.TEXT,
BarcodeFormat.QR_CODE.toString(),
smallerDimension);
Bitmap bitmap = qrCodeEncoder.encodeAsBitmap();
}

first you will need to add zing2.1.jar file in your project then do the below code
QRCodeEncoder.java
public final class QRCodeEncoder {

Do the below code to add string and set it to ImageView

Contents.Type.TEXT, BarcodeFormat.QR_CODE.toString(), qrCodeDimention);
try {

imageView.setImageBitmap(bitmap);

I dont know which library are you using.
I am calling my zxing library QRReaderActivity in my app like this.
startActivity(QRReaderActivity.class);
the method is
private void startActivity(Class<?> className) {
Intent intent = new Intent(this, className);
startActivityForResult(intent, 0);
}

Using Android USB Host API to read my USB game controller/Or other USB device data

I am trying to use Android USB Host API to read my USB game controller data, once I get this to work, I will connect other device to test.
My game controller is connected to my Android phone using OTG cable. I am now able to get device, endpoints information, but I don't know how to read the raw data and display it.
Can someone please help me? Some example codes will be appreciated.

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).

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 ;)
