Debugging Android App communicating with Servlet on real device

So the scenario is I am trying to debug a simple application on my real device.I am using eclipse to make the application.
Now my application is communicating with a servlet which is on Server and application is running very smoothly in genymotion emulator(not using the emulator provided by eclipse). But when I try to run it in my device it is working perfectly till one activity class,but application is crashing on second activity.
So, after so many searches I am posting this question here. Hope I can find out any solution for this.
This is my Second Activity:
public void onCreate(Bundle savedInstanceState) {

If you use a real device you need to use the real IP of the server. Keep also in mind to open the required ports for your local network and connect your mobile with your local network via WiFi.
I'm not very familar with the secutity of servlets check also that you can connect to the server with a second computer too. (Depending on your configuration it is possible that you cannot access the server from outside of "localhost")

cb.setTextColor(Color.BLACK);

cb.setButtonDrawable(R.drawable.checkbox);

} else {
Toast.makeText(getApplicationContext(), "data empty",
Toast.LENGTH_LONG).show();
mpv.setEnabled(true);
discount.setEnabled(true);
}
pDialog.dismiss();
}
}
}

Just do this inside the loop and if , else condition
cb.setTag(i+99); // set the tag values so that you can refer to them later.
cb.setOnCheckedChangeListener(handleCheck(cb)); // here pass the checkbox object.
Then this is handleCheck method
private OnCheckedChangeListener handleCheck (final CheckBox chk)
{
return new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(!isChecked){
Toast.makeText(getApplicationContext(), "You unchecked " + chk.getTag(),
Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "You checked " + chk.getTag(),
Toast.LENGTH_LONG).show();
}
}
};
}
Hope this gives you some idea. Happy coding :)

InsertAPN() Method Does Not Write APN Settings - Android 2.3.6

I have an android application which is supposed to write new APN settings to a device however every time I run the application the new APN settings do not appear to be written to the device (the APN settings are totally blank after execution) I belive this may have something to do with a problem with InsertAPN() [shown below] however I'm unable to determine the root cause of the issue.
P.S.
Any debugging tips/questions are greatly appreciated.

You can no longer programatically change APN settings on Android 4.0 and up. So if you're debugging on Android 4.0 or higher, that is where your issue is.

An error connecting to Android Spinner

I am working on an Android app where I have a Spinner, and on the base of which item I choose, the app will read in text file number 1 or number 2, etc... I have written a code, but when I run it on my device, it says that "The application has stopped unexpectedly".
Here is my code:
public class MainActivity extends Activity implements OnClickListener, OnItemSelectedListener {
Spinner spinner;
String textSource = "";
TextView textMsg;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textMsg = (TextView) findViewById(R.id.textmsg);
spinner=(Spinner) findViewById(R.id.spinner1);
List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(this);
URL textUrl;
String stringText = "";
try {
textUrl = new URL(textSource);
BufferedReader bufferReader = new BufferedReader(
new InputStreamReader(textUrl.openStream(), "ISO-8859-1"));
//ISO-8859-1
String StringBuffer;
//String stringText = "";
while ((StringBuffer = bufferReader.readLine()) != null) {
stringText += StringBuffer;
}
bufferReader.close();
textMsg.setText(stringText);
//textMsg.setText(string123);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
textMsg.setText(e.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
textMsg.setText(e.toString());
}
}
#Override
public void onItemSelected(AdapterView<?> parent, View arg1, int pos,
long arg3) {
// TODO Auto-generated method stub
String Text = parent.getSelectedItem().toString();
if(Text.equals("list 1")) {
textSource = "path/to/textfile 1";
}
else if(Text.equals("list 2")){
textSource = "path/to/textfile 2";
}
else {
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
How should I solve this problem?
Thanks for helping

I would suggest you to use
String Text = spinner.getSelectedItem().toString();
instead of
String Text = parent.getSelectedItem().toString();
So that it becomes :
#Override
public void onItemSelected(AdapterView<?> parent, View arg1, int pos,
long arg3) {
String Text = spinner.getSelectedItem().toString();
if(Text.equals("list 1")) {
textSource = "path/to/textfile 1";
}
else if(Text.equals("list 2")){
textSource = "path/to/textfile 2";
}
else {
}
// then put your URL code here as follows
URL textUrl;
String stringText = "";
try {
textUrl = new URL(textSource);
BufferedReader bufferReader = new BufferedReader(
new InputStreamReader(textUrl.openStream(), "ISO-8859-1"));
//ISO-8859-1
String StringBuffer;
while ((StringBuffer = bufferReader.readLine()) != null) {
stringText += StringBuffer;
}
bufferReader.close();
textMsg.setText(stringText);
//textMsg.setText(string123);
} catch (MalformedURLException e) {
e.printStackTrace();
textMsg.setText(e.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
textMsg.setText(e.toString());
}
}

Since you are calling textUrl = new URL(textSource); inside oncreate() method textSource will be always " ". Better create a method and pass the new textSource value based on onItemSelected .
Sample for Your reference: By Default Link1 will be passed
#Override
public void onItemSelected(AdapterView<?> parent, View arg1, int pos,
long arg3) {
String Text = parent.getSelectedItem().toString();
if (Text.equals("list 1")) {
Method("path/to/textfile 1");
} else if (Text.equals("list 2")) {
Method("path/to/textfile 2");
} else {
}
// TODO Auto-generated method stub
}
Method :
public void Method(String textSource) {
URL textUrl;
String stringText = "";
try {
textUrl = new URL(textSource);
BufferedReader bufferReader = new BufferedReader(
new InputStreamReader(textUrl.openStream(), "ISO-8859-1"));
// ISO-8859-1
String StringBuffer;
// String stringText = "";
while ((StringBuffer = bufferReader.readLine()) != null) {
stringText += StringBuffer;
}
bufferReader.close();
textMsg.setText(stringText);
// textMsg.setText(string123);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
textMsg.setText(e.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
textMsg.setText(e.toString());
}
}
