Generate PDF file and attach to e-mail

first post here.
I have read all similar posts without finding any answer, i'm a newbie at dev in general.
Here is what i'm looking for:
On button click, the code generates a PDF with some info, and i just want to send the created pdf by mail.
First problem is when i choose an email app to send the mail, i got a message "Impossible to attach file".
Second problem is that the created file is not readable on the phone while it's readable on PC.
By searching i found out that it may be in relation with permission. I tried setReadablemethod without result. Android studio makes a hint (result of setReadable is ignored).

How to read a CSV file?

I am creating an application where i do some real-time image analysis and store them into a csv file. The csv has 2 columns time and y-value of each frame.
I want to read this file and store the values from 2 columns into to double array. I want this because i want to perform an fast Fourier transformation on the data.
public class MainActivity extends AppCompatActivity implements CameraView.PreviewReadyCallback {
private static Camera camera = null;
private CameraView image = null;
private LineChart bp_graph;
private int img_Y_Avg, img_U_Avg, img_V_Avg;

//open camera
try {
camera = Camera.open();
handler = new Handler();
final Runnable runnable = new Runnable() {
#Override
public void run() {
camera.stopPreview();
camera.release();
}

public void readCsv(){

This is my MainActivity. What I am doing here is getting the data from CameraView class for each frame with the help of an interface that I created. After that im storing the values into a CSV file called temporary.csv.
Issues
I want to read this csv and store the first column(the time) into one double array and the second column(yAverage) into another double array.
I also want to delete the file once i have all the data stored into the into the double array.
How can I do that?

I would suggest youto use an open source library like OpenCSV to get the datafrom the CSV file. When you have the library implemented it's only a matter of iterating through the x and y columns and assign them to an array. With OpenCSV it would look like that. But i would also suggest you an more object orientec approach if the x and y with the same index coords are related to each other.
String csvFile = "/Users/mkyong/csv/country3.csv";
int length = 100; //If you dont know how many entries the csv file has i would suggest to use ArrayList
double[] xCoords = new double[length];
double[] yCoords = new double[length];
CSVReader reader = null;
try {
reader = new CSVReader(new FileReader(csvFile));
String[] line;
int i = 0;
while ((line = reader.readNext()) != null) {
xCoords[i] = Double.parseDouble(line[0]);
yCoords[i] = Double.parseDouble(line[1]);
}
} catch (IOException e) {
e.printStackTrace();
}

From the answer given by Lucas, I got the direction to my solution
public void readCsv(){
//set the path to the file
String getPath = Environment.getExternalStorageDirectory() + "/bpReader";
String csvFile = "temporary.csv";
String path = getPath+ "/" + csvFile;
//File file = new File(path, csvFile);
int length = 500;
double[] xCoords = new double[length];
double[] yCoords = new double[length];
CSVReader reader = null;
try {
File myFile = new File (path);
reader = new CSVReader(new FileReader(myFile));
String[] line;
int i = 0;
while ((line = reader.readNext()) != null) {
xCoords[i] = Double.parseDouble(line[0]) ;
yCoords[i] = Double.parseDouble(line[1]);
Log.d("read:: ", "Time: "+String.valueOf(xCoords[i])+" Y: "+String.valueOf(yCoords[i]));
}
myFile.delete();
} catch (IOException e) {
e.printStackTrace();
}
}
And then i had to add
// https://mvnrepository.com/artifact/org.apache.commons/commons-lang3
compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.6'
to my gradle,, which can be found at MVN repository

Check duplicate editText before writing into .csv

I have several editText in my FirstActivity for CSV:
Button save;
CSV csv;
StringBuffer filePathc;
public final static String EXTRA_MESSAGE = "com.example.mapcard.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_card);
txtName= (EditText) findViewById(R.id.txtName);
txtCompany= (EditText) findViewById(R.id.txtCompany);
txtPhone= (EditText) findViewById(R.id.txtPhone);
txtMobile = (EditText) findViewById(R.id.txtMobile);
txtAddress = (EditText) findViewById(R.id.txtAddress);
txtEmail = (EditText) findViewById(R.id.txtEmail);
txtWebsite = (EditText) findViewById(R.id.txtWebsite);
txtTitle = (EditText) findViewById(R.id.txtTitle);
filePathc = new StringBuffer();
filePathc.append("/sdcard/Android/data/");
file = new File(filePathc+filename.toString());
csv = new CSV(file);
save=(Button)findViewById(R.id.save);
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
csv.writeHeader(txtName.getText().toString()+ ","
+txtCompany.getText().toString()
+ "," +txtPhone.getText().toString()
+ "," +txtMobile.getText().toString()
+ "," +txtAddress.getText().toString()
+ "," +txtEmail.getText().toString()
+ "," +txtWebsite.getText().toString()
+ "," +txtTitle.getText().toString());
Intent intent = new Intent(NewCard.this, Template.class);
intent.putExtra("name", Name);
intent.putExtra("company", Company);
intent.putExtra("phone", Phone);
intent.putExtra("mobile", Mobile);
intent.putExtra("address", Address);
intent.putExtra("email", Email);
intent.putExtra("website", Website);
intent.putExtra("title", Title);
startActivity(intent);
SecondActivity is to write this data into .csv file:
public class CSV {
private PrintWriter csvWriter;
private File file;
public CSV(File file) {
this.file = file;
}
public void writeHeader(String data) {
try {
if (data != null) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}}
File in directory is successfully created and data is inserted. I am trying to check the data like Name or Email, if it is duplicate/already recorded to not save into .csv and warn user with Toast "same data".
I think it is something to do with line:
try {
if (data != null) {
Your helps and suggestions are appreciated. Thank you.

Use following function
public boolean exist(String newData){
try {
FileInputStream fIn = new FileInputStream(file);
BufferedReader myReader = new BufferedReader(
new InputStreamReader(fIn));
String aDataRow = "";
String aBuffer = "";
while ((aDataRow = myReader.readLine()) != null) {
if(aDataRow.contains(newData))//<--check if data exists
return true;
}
txtData.setText(aBuffer);
myReader.close();
} catch (Exception e) {
}
return false;
}
And change your write header function to:
public void writeHeader(String data) {
try {
if (data != null&&!data.isEmpty()&&!exist(data)) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}

data != null doesnt cover the case that the String is just empty, but not null. So basically you get "" from the textview by calling getText(). adding && !"".equals(data) should fix that problem
UPDATE
Well, there is a difference between an empty, and an uninitalized String. An uninitalized String means you declared it like String a; but nothing further.
If you use editText.getText() the editText will return a String which has been initialized but contains only what is currently in it. So basically if there is nothing in the editext it will return "".
And to sum this up:
String a;
null == "" // false
a == null // true
"".equals(editText.getTExt()) // true if the editext doesnt contain anything

Android: ParsingXMLFiles only gets the values for the first XML

Hi I have designed a File Explorer which I use to show some XML files and depending on the selected one I open one XML or another. Until the moment there is no problem at all and with the help of XMLPullParser I insert the text from the attributes into some ArrayLists. The problem is that IF I go back and I select another XML file these values are the same as the following XML and that happens with the following XMLs. I think that the problem is that the arrayLists don´t get empty once a new instance is called.
Here is how this works:
FileExporer where I show the files and I click on anyone.
public class MainActivity extends ListActivity {
private List<String> item = null;
private List<String> path = null;
private String root;
private TextView myPath;
static File file;
static String texto;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myPath = (TextView)findViewById(R.id.path);
root = Environment.getExternalStorageDirectory().getPath();
getDir(root);
}
private void getDir(String dirPath)
{
myPath.setText("Location: " + dirPath);
item = new ArrayList<String>();
path = new ArrayList<String>();
File f = new File(dirPath);
File[] files = f.listFiles();
if(!dirPath.equals(root))
{
item.add(root);
path.add(root);
item.add("../");
path.add(f.getParent());
}
for(int i=0; i < files.length; i++)
{
File file = files[i];
if(!file.isHidden() && file.canRead() && (file.getName().endsWith("xml"))){
path.add(file.getPath());
if(file.isDirectory()){
item.add(file.getName() + "/");
}else{
item.add(file.getName());
}
}
}
ArrayAdapter<String> fileList =
new ArrayAdapter<String>(this, R.layout.row, item);
setListAdapter(fileList);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
file = new File(path.get(position));
if (file.isDirectory())
{
if(file.canRead()){
getDir(path.get(position));
}else{
new AlertDialog.Builder(this)
.setIcon(R.drawable.ic_launcher)
.setTitle("[" + file.getName() + "] folder can't be read!")
.setPositiveButton("OK", null).show();
}
}else {
file = new File(path.get(position));
file.getName();
XMLPullParser.Parse(this);
texto = XMLPullParserHandler.getA(0);
}
Parseo();
Intent i = new Intent(MainActivity.this, Correccion.class);
startActivity(i);
MainActivity.this.finish();
}
public void Parseo(){
}
public static String fileName(){
return file.getName();
}
public static String getText(){
return texto;
}
}
XMLPullParser: It says the file that need to be read and calls a new isntance of XMLPullParserHandler.
public class XMLPullParser{
static String Fichero;
public static void Parse(Context context){
try {
List<Puntuacion> puntuacion;
XMLPullParserHandler parser = new XMLPullParserHandler();
File dir = Environment.getExternalStorageDirectory();
File yourFile = new File(dir, MainActivity.fileName());
FileInputStream iStream = new FileInputStream(yourFile);
puntuacion = parser.parse(iStream);
} catch (IOException e) {
e.printStackTrace();
}
}
}
XMLPullParserHandler: I think that here is the problem, when I create and add text to the ArrayLists: For example in this case in ArrayList a
public class XMLPullParserHandler {
List<Puntuacion> puntuaciones;
private Puntuacion puntuacion;
static List<String> nombres = new ArrayList<String>();
static List<String> a = new ArrayList<String>();
private String text;
public XMLPullParserHandler() {
// puntuaciones.clear();
// puntuaciones.removeAll(puntuaciones);
puntuaciones = new ArrayList<Puntuacion>();
;
}
public List<Puntuacion> getPuntuacion() {
return puntuaciones;
}
public List<Puntuacion> parse(InputStream is) {
XmlPullParserFactory factory = null;
XmlPullParser parser = null;
try {
factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
parser = factory.newPullParser();
parser.setInput(is, null);
int eventType = parser.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
String tagname = parser.getName();
switch (eventType) {
case XmlPullParser.START_TAG:
if (tagname.equalsIgnoreCase("TEST")) {
// create a new instance of puntuacion
puntuacion = new Puntuacion();
}
break;
case XmlPullParser.TEXT:
text = parser.getText();
break;
case XmlPullParser.END_TAG:
if (tagname.equalsIgnoreCase("TEST")) {
puntuaciones.add(puntuacion);
} else if (tagname.equalsIgnoreCase("NUMERO_ACIERTOS")) {
puntuacion.setValor_Transformado((text));
a.add(text);
Log.i("ii", text);
}
break;
default:
break;
}
eventType = parser.next();
}
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return puntuaciones;
}
public static String getNombre(int posicion){
String[] ListN = new String[nombres.size()];
ListN = nombres.toArray(ListN);
return ListN[posicion];
}
public static String getA(int posicion){
String[] ListA = new String[a.size()];
ListA = a.toArray(ListA);
return ListA[posicion];
}
}
For example if I have in this case a XML with **<NUMERO_ACIERTOS>1</NUMERO_ACIERTOS>** and after this I read another one with **<NUMERO_ACIERTOS>3</NUMERO_ACIERTOS>** in my UI I only see the value **1** because is the first that has been loaded into the arraylist.
thank you for your time and attention.

No me gustan estos:
static List<String> nombres = new ArrayList<String>();
static List<String> a = new ArrayList<String>();
They should not be static, and probably should be private:
private List<String> nombres;
private List<String> a;
I think they should be created new when you start your parse like this:
public List<Puntuacion> parse(InputStream is) {
XmlPullParserFactory factory = null;
XmlPullParser parser = null;
nombres = new ArrayList<String>();
a = new ArrayList<String>();
try {
¡Buena suerte!

Parsing error in Android

I am storing an array of numbers as string(I get the string from shared preferences) and then trying to parse it.
But when I use parseInt my app crashes. The activity Second is called by Main class.

public int[] x = new int[50];
public int[] y = new int[50];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
SharedPreferences data= getSharedPreferences("data",0);
SharedPreferences.Editor editor= data.edit();
StringBuilder str = new StringBuilder();
str.append(data.getString("val", "0")).append(",").append(getIntent().getExtras().getString("thetext"));
String end = str.toString();
editor.putString("val", end);
editor.commit();
//EditText et1= (EditText) findViewById(R.id.editText2);
//et1.
String savedString = data.getString("val", "0");
savedString.replaceAll("\\s","");
String[] st = savedString.split(",");
int i;
for(i=0;i<st.length;i++){
st[i].trim();
Log.d("Debug" , "st["+i+"] = "+st[i]);
x[i] = Integer.valueOf(st[i]);
y[i]=i;}
}
public void lineGraphHandler (View view)
{
LineGraph line = new LineGraph();
Intent lineIntent = line.getIntent(this);
startActivity(lineIntent);
}
}
Where is it going wrong?

Add a line between these
st[i].replaceAll("\\s","");
Log.d("Debug" , "st["+i+"] = "+st[i])
x[i] = Integer.parseInt(st[i]);
and see that if that is a convertible string or there are some letters accidently inserted that can't be converted to int?
