Java: Can't convert string to array

I can't convert a string to an array!
String text = "";
String[] textsplit = {};
//Stuff
The app set the content of an online txt file in a string:
The online txt file contain: hello,my,name,is,simone
[...] //Downloading code
text = bo.toString(); //Set the content of the online file to the string
Now the string text is like this:
text = "hello,my,name,is,simone"
Now i have to convert the string to an array that must be like this:
textsplit = {"hello","my","name","is","simone"}
so the code that i use is:
textsplit = text.split(",");
But when i try to use the array the app crash! :(
For example:
textview.setText(textsplit[0]); //The text of the textview is empity
textview.setText(textsplit[1]); //The app crash
textview.setText(textsplit[2]); //The app crash
etc...
where am I wrong? thanks!
EDIT: This is the code:
new Thread() {
#Override
public void run() {
String path ="http://www.luconisimone.altervista.org/ciao.txt";
URL u = null;
try {
u = new URL(path);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.connect();
InputStream in = c.getInputStream();
final ByteArrayOutputStream bo = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
in.read(buffer); // Read from Buffer.
bo.write(buffer); // Write Into Buffer.
runOnUiThread(new Runnable() {
#Override
public void run() {
text = bo.toString();
testo.setText("(" + text + ")");
try {
bo.close();
} catch (IOException e) {
e.printStackTrace();
}
}
});
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
// Here all variables became empity
textsplit = text.split(",");
datisplittati.setText(textsplit[0]);

Try :
String text = "hello,my,name,is,simone";
String[] textArr = text.split(Pattern.quote(","));

You can get string using AsyncTask
private class GetStringFromUrl extends AsyncTask<String, Void, String> {
ProgressDialog dialog ;
#Override
protected void onPreExecute() {
super.onPreExecute();
// show progress dialog when downloading
dialog = ProgressDialog.show(MainActivity.this, null, "Downloading...");
}
#Override
protected String doInBackground(String... params) {
// #BadSkillz codes with same changes
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(params[0]);
HttpResponse response = httpClient.execute(httpGet);
HttpEntity entity = response.getEntity();
BufferedHttpEntity buf = new BufferedHttpEntity(entity);
InputStream is = buf.getContent();
BufferedReader r = new BufferedReader(new InputStreamReader(is));
StringBuilder total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line + "\n");
}
String result = total.toString();
Log.i("Get URL", "Downloaded string: " + result);
return result;
} catch (Exception e) {
Log.e("Get Url", "Error in downloading: " + e.toString());
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
// TODO change text view id for yourself
TextView textView = (TextView) findViewById(R.id.textView1);
// show result in textView
if (result == null) {
textView.setText("Error in downloading. Please try again.");
} else {
textView.setText(result);
}
// close progresses dialog
dialog.dismiss();
}
}
and use blow line every time that you want:
new GetStringFromUrl().execute("http://www.luconisimone.altervista.org/ciao.txt");

You're using new thread to get data from an url. So in runtime, data will be asynchronous.
So when you access text variable (split it), it's still not get full value (example reason: network delay).
Try to move the function split after text = bo.toString(); , I think it will work well.

Android Show Internal Data in to textviews

I am working on an app where I need to save/read my files from Internal storage.
But it read all my data in the same TextView.
Can someone show me show,how to show the data in 2 textviews, or to show me how put the one data under the other data.
Here is my code for saving data:
private void SaveMode() {
String FILENAME ;
String Strin1= textview1.getText().toString();
String String2= textview2.getText().toString();
EditText filename1 = (EditText) findViewById(R.id.filename);
FILENAME = filename1.getText().toString();
if (FILENAME.contentEquals("")){
FILENAME = "UNTITLED";
}
String1 = textview1.getText().toString();
String2= textview2.getText().toString();
FileOutputStream fos = null;
try {
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
try {
fos.write("Strin1.getBytes());
fos.write(String2.getBytes());
} catch (IOException e) {
e.printStackTrace();
}
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
And here is my code for read my data:
private void getFilenames() {
String[] filenames = getApplicationContext().fileList();
List<String> list = new ArrayList<String>();
for(int i = 0; i<filenames.length; i++){
//Log.d("Filename", filenames[i]);
list.add(filenames[i]);
}
ArrayAdapter<String> filenameAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, list);
spinner.setAdapter(filenameAdapter);
}
public void SpinnerClick(View v) {
String selectFile = String.valueOf(spinner.getSelectedItem());
openFile(selectFile);
}
private void openFile(String selectFile) {
showData = (TextView) findViewById(R.id.show_data);
TextView showData1 = (TextView) findViewById(R.id.show_data1);
String value = "";
FileInputStream fis;
try {
fis = openFileInput(selectFile);
byte[] input = new byte[fis.available()];
while(fis.read(input) != -1){
value += new String(input);
fis.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
showData.setText(value);
}
EDIT
I tried to edit my read code like this, but with no luck
private void openFile(String selectFile) {
TextView showData = (TextView) findViewById(R.id.show_data);
TextView showData2 = (TextView) findViewById(R.id.show_data2);
String value = "";
String[] strArray = value.split(";");
try {
FileInputStream fis = openFileInput(selectFile);
byte[] input = new byte[fis.available()];
while(fis.read(input) != -1){
value += new String(input);
}
fis.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
showData.setText(value);
showData.setText(strArray[0]);
showData2.setText(strArray[1]);
}
Edit 2
Got it to work with Shobhit Puri codes

First while saving your data you might insert a delimiter in between those two string. Make sure that delimiter is not the one expected in your textViews.
While saving:
String string3 = ";";
try {
fos.write("Strin1.getBytes());
fos.write("String3.getBytes());
fos.write(String2.getBytes());
} catch (IOException e) {
e.printStackTrace();
}
Then when you are trying to read it into value string, then split is using .split function. Eg:
String[] strArray = value.split(";");
strArray[0] will give first textview's sting and strArray[1] will give the second.
Update
private void openFile(String selectFile) {
TextView showData = (TextView) findViewById(R.id.show_data);
TextView showData2 = (TextView) findViewById(R.id.show_data2);
String value = "";
try {
FileInputStream fis = openFileInput(selectFile);
byte[] input = new byte[fis.available()];
while(fis.read(input) != -1){
value += new String(input);
}
fis.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String[] strArray = value.split(";");
showData.setText(strArray[0]);
showData2.setText(strArray[1]);
}

try
{
FileInputStream fis = new FileInputStream(myInternalFile);
DataInputStream in = new DataInputStream(fis);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine = br.readLine()) != null) {
myData = myData + strLine;
}
in.close();
} catch (IOException e) {
e.printStackTrace();
}
myInputText.setText(myData);

Why does getElementsByTag throw NullPointerException?

I'm trying to parse xml data from this URL:http://cloud.tfl.gov.uk/TrackerNet/LineStatus but am getting a NullPointerException on the line that read:
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
Before I show the code, I'd just like to say whats going on. First I download the XML file to the SDCard in
saveToSdCard();
Then I retrieve it with
getDataFromSDcard();
Here is my code:

For loop does not doing my async task completely

Im doing Download All of files. What I did was for loop, unfortunately my for loop does not finish my async task it continues doing all the loop regardless if it finished the first file that was downloading. Help please.

An asynchronous task runs on a background thread, so you directly access variable dload_all in function doInBackground() that is not thread safe. Maybe you can try:
private void startDownloadall() {
//String fileURL = dload_all;
//fileURL = fileURL.replace(" ", "%20");
new DownloadFileAsync1().execute(dload_all, id_all);
Toast.makeText(getApplicationContext(), "Downloading...start all", Toast.LENGTH_LONG).show();
}

#Override

//showDialog(DIALOG_DOWNLOAD_PROGRESS);

try {
String fileURL = args[0];
fileURL = fileURL.replace(" ", "%20");

HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);

String PATH = getDir("ebook", MODE_PRIVATE).toString();
String ebookfile = "";
//String filename = id[index];

Android: Epub file not showing images in emulator/android device

I am using http://www.siegmann.nl/epublib to read epub file. My code is mentioned below.
try {
book = epubReader.readEpub(new FileInputStream("/sdcard/EpubTesting.epub"));
Resource res;
Spine contents = book.getSpine();
List<SpineReference> spinelist = contents.getSpineReferences();
StringBuilder string = new StringBuilder();
String line = null;
int count = spinelist.size();
for (int i=0;i<count;i++){
res = contents.getResource(i);
try {
InputStream is = res.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
try {
while ((line = reader.readLine()) != null) {
linez = (string.append(line+"\n")).toString();
}
} catch (IOException e) {e.printStackTrace();}
} catch (IOException e) {
e.printStackTrace();
}
}
System.out.println(linez);
s1.loadDataWithBaseURL("/sdcard/",linez, "text/html", "UTF-8",null);
}catch (FileNotFoundException e) {
Toast.makeText(mContext, "File not found.", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
Toast.makeText(mContext, "IO Exception.", Toast.LENGTH_SHORT).show();
}
Also tried
s1.loadDataWithBaseURL("",linez, "text/html", "UTF-8",null);
s1.loadDataWithBaseURL("file://mnt/sdcard/",linez, "text/html", "UTF-8",null);
But result is sifar. Please tell me what I have to do to show the contained images in file. I have gone through FAQ says Make a subclass of android.webkit.WebView that overloads the loadUrl(String) method in such a way that it loads the image from the Book instead of the internet. But till I don't where they extract the file how can I locate the path. Please tell me. I am very confused. Thanks in advance.

For that you have to download all resources of epub files (i.e. images,stylesheet) in location where you downloaded .epub file in sdcard. please check below code to download images and css files from .epub files itself using epublib.
for that u have to send parameter of File objects where you want to store those images.
private void DownloadResource(File FileObj,String filename) {
try {
InputStream epubis = new FileInputStream(FileObj);
book = (new EpubReader()).readEpub(epubis);
Resources rst = book.getResources();
Collection<Resource> clrst = rst.getAll();
Iterator<Resource> itr = clrst.iterator();
while (itr.hasNext()) {
Resource rs = itr.next();
if ((rs.getMediaType() == MediatypeService.JPG)
|| (rs.getMediaType() == MediatypeService.PNG)
|| (rs.getMediaType() == MediatypeService.GIF)) {
File oppath1 = new File(directory, "Images/"
+ rs.getHref().replace("Images/", ""));
oppath1.getParentFile().mkdirs();
oppath1.createNewFile();
FileOutputStream fos1 = new FileOutputStream(oppath1);
fos1.write(rs.getData());
fos1.close();
} else if (rs.getMediaType() == MediatypeService.CSS) {
File oppath = new File(directory, "Styles/"
+ rs.getHref().replace("Styles/", ""));
oppath.getParentFile().mkdirs();
oppath.createNewFile();
FileOutputStream fos = new FileOutputStream(oppath);
fos.write(rs.getData());
fos.close();
}
}
} catch (Exception e) {
Log.v("error", e.getMessage());
}
}
after this use this your code to set path of images in webview.
if stored in sd card then
s1.loadDataWithBaseURL("file:///sdcard/",linez, "text/html",null,null);
or
s1.loadDataWithBaseURL("file://mnt/sdcard/",linez, "text/html", "UTF-8",null);
if in internal storage then
s1.loadDataWithBaseURL("file:///data/data/com.example.project/app_mydownload/",linez, "text/html",null,null);
