[Q] How download file in internal storage?

Hello, I want to download a xml file in local storage that I will parse.
The code is this
URL website = new URL("http://juventus.com/rss/news/ita.xml");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(c.getFilesDir()+"/eng.xml");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
This is called in doInBackground() of a AsyncTask class.
I get this error:
08-01 22:17:40.061: E/AndroidRuntime(9002): java.lang.RuntimeException: An error occured while executing doInBackground()
08-01 22:17:40.061: E/AndroidRuntime(9002): Caused by: java.lang.IllegalArgumentException: position=0 count=9223372036854775807
08-01 22:17:40.061: E/AndroidRuntime(9002): at java.nio.FileChannelImpl.transferFrom(FileChannelImpl.java:359)
What I do wrong?
I also tried this:
URL website = new URL("http://juventus.com/rss/news/ita.xml");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = c.openFileOutput("eng.xml", Context.MODE_PRIVATE);
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
Hope you help me.
Thanks!

Try this...
Code:
URLConnection conn;
Log.d(TAG, "onDownload....path is: " + path);
try {
URL url = new URL(path);
conn = url.openConnection();
contentLength = conn.getContentLength();
DataInputStream in = new DataInputStream(conn.getInputStream());
Log.d(TAG, "Buffering the received stream(size=" + contentLength);
if (contentLength != -1) {
buffer = new byte[contentLength];
in.readFully(buffer);
in.close();
}else{
result = false;
return;
}
if (buffer.length > 0) {
Log.d(TAG,
"onDownload. Writing file to files dir,");
DataOutputStream out;
FileOutputStream fos = context.openFileOutput(fileName,
Context.MODE_PRIVATE);
Log.d(TAG, "Writing from buffer to the new file.." + fileName);
out = new DataOutputStream(fos);
out.write(buffer);
out.flush();
out.close();
result = true;
Edit: Here I am returning a boolean to indicate successful download.

[Q] Insert multiple records using webservice in android

I have been following this forum for quite a long time now, but I have not decided to publish my questions here.
Hope anyone can help me with this:
I am developing an android app that gets the calls made in a day, and I want those calls to be inserted into a SQL server table using a webservice.
I am kind of an android begginer, since I have never worked with webservices.
So far I am able to get the information of the calls and show it in the display and to insert up to 3-4 records in the database. the problem that I am facing right now is that when I get to insert more than 3 records, the webservice inserts duplicate entries and the call duration gets set to 0 in every call. For example: I have calls to the numbers 1,2,3,4 with a duration of 5 seconds each. When I invoke the webservice, it inserts the call 1,3,3,3 with duration of 0 seconds in all of the calls.
I am adding the code of my Activity and some captions of the device and the SQL server. If you need any more code, just let me know.
Thanks everyone!

Could you please be more specific about your errors? Error output from eclipse in case of compile error or if it did compile but has runtime errors then post the logcat output for example. This would help
Edit::
Well for the first i wouldnt distribute the onclick listeners so much, instead let your activity implement OnClickListener so you have one onClick method for all, that is far more ordered. Then put a switch inside it: switch (v.getId()) { //v is the clicked button
case R.id.btnLogin:
//login button code here
case R.id. .... :
......
}
Then it is more structured

Wich IDE are you using ?
If you can't run it it means that it's a compilation failure, probably a syntax error. Most of Java IDE tells you where is the error even before you run it.

ClassBody"
and also i would like to now how to make the classes actually connect to eachother... also Im using eclipse to run my project.. and if theres anything else that just looks wrong please point it out so i the future ill notice them

thanks means alot helped a lot im starting to notice the errors im actually laughin at myself with a couple of the errors.... im still getting a error in regard to the last couple curly brackets "Multiple markers at this line
- Syntax error, insert ";" to complete
Statement
- Syntax error, insert "}" to complete
ClassBody
- Syntax error, insert ")" to complete
Expression"
i know it just a } somewhere or something but how can u just be able to tell where it need to be placed

Well it tells you which line it is, take a look at it (probably where you close your second on click listener in the second activity). Remember that each bracket, curly or round has to get closed before the statement can be finished with a ; . Another thing I just noticed, you now set the onClickListener for btnRegister twice in the second activity, you can't do that. Probably the code of the first one should be executed after the code in the other click listener.

Well read the whole thing, at the line in bold it tells you that you have a NullPointerException at line 44 of the Login activity. You should read nikwen's guide on logcats and debugging .

If you want to check that some data is actually present then just write it to the log. Eg.
Log.V("Testing", someString);
If it is working then someString will be printed after the "Testing" tag. If its not then you should check your logcat to find out why not.

Can Someone Help Me On Finding The Cause Of Crash Of This Code

I'm trying to get the result of the asynctask by using an interface but when I've tried to use the methods on that interface my app keeps on crashing.
This project has 4 java files: MainActivity.java , SigninActivity.java , GetAvailableExam.java , AsyncResponse.java
I'm pretty sure the error is not on the GetAvailableExam.java because it is just an activity that prints hello world so I'm not going to post it's code here.
MainActivity.java
Code:
package com.it4.anexsysclient;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity implements AsyncResponse {
private EditText usernameField,passwordField;
private TextView status,role,method;
SigninActivity signinactivity = new SigninActivity();
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
usernameField = (EditText)findViewById(R.id.editText1);
passwordField = (EditText)findViewById(R.id.editText2);
status = (TextView)findViewById(R.id.textView6);
role = (TextView)findViewById(R.id.textView7);
method = (TextView)findViewById(R.id.textView9);
signinactivity.delegate = this;
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu(Menu menu) {
usernameField.setText("stud");
passwordField.setText("stud");
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void login(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Get Method");
new SigninActivity(this,status,role,0).execute(username,password);
}
public void loginPost(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Post Method");
new SigninActivity(this,status,role,1).execute(username,password);
}
public void processFinish(String output){
//Toast.makeText(getApplicationContext(), output, Toast.LENGTH_LONG).show();
}
}

{

break;
}
return sb.toString();
}catch(Exception e){
return new String("Exception: " + e.getMessage());
}
}
}
[user=439709]@override[/user]
protected void onPostExecute(String result){
this.statusField.setText("Login Successful");
this.roleField.setText(result);
this.progress.dismiss();
delegate.processFinish(result);
//Log.d("ADebugTag", "Value: " + result);
//if(result.toString()=="student") {
//context.startActivity(new Intent(context, GetAvailableExam.class));
//}
}
}
AsyncResponse.java
Code:
package com.it4.anexsysclient;
public interface AsyncResponse {
void processFinish(String output);
}
Code:
protected void onPostExecute(String result){
this.statusField.setText("Login Successful");
this.roleField.setText(result);
this.progress.dismiss();
delegate.processFinish(result);
//Log.d("ADebugTag", "Value: " + result);
//if(result.toString()=="student") {
//context.startActivity(new Intent(context, GetAvailableExam.class));
//}
}
The delegate.processFinish(result) is the one causing the crash, The app works fine if I try to remove/comment out it.

Would be helpfull with some more information, for instance: what exception is it you get?
My guess is a nullpointer? Which by a quick glance i'd suspect is that you never set "delegate" in your signinactivity.
You create signinactivity during creation of mainactivity.
Code:
[B]SigninActivity signinactivity = new SigninActivity();[/B]
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
usernameField = (EditText)findViewById(R.id.editText1);
passwordField = (EditText)findViewById(R.id.editText2);
status = (TextView)findViewById(R.id.textView6);
role = (TextView)findViewById(R.id.textView7);
method = (TextView)findViewById(R.id.textView9);
[B]signinactivity.delegate = this;[/B]
}
However that instance is later never used from what i can tell? You create new instances later in code when its used, where delegate won't be set.
Code:
public void login(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Get Method");
[B]new SigninActivity(this,status,role,0).execute(username,password);[/B]
}
public void loginPost(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Post Method");
[B] new SigninActivity(this,status,role,1).execute(username,password);[/B]
}
