Unfortunately I cannot upload the PDF file, but I have included the image(cropped) to understand the text layout and associated values.
There are two issues that I am facing now:
Some of the numerical value is getting split, in the image value 2,020,735 is getting split as 2 and ,020,735 two separate text blocks. When I set the sortByPosition to false I am getting the correct numerical values but, I need the sortByPosition set to true
The orientation angle is 90 in this case for the text in PDF which is surprising, as all the text is horizontal as displayed in the image above
I am not sure when I am going wrong.

List pdf Attachments using PDFBox (Java)

I'd like to get all filenames of attachments/embedded files of a PDF document. I've been searching for a long time now, but my code still doesn't work.
What I tried:
File input = new File(inputfile); // Input File Path, Given as param from args[]
pd = PDDocument.load(input);
PDDocumentNameDictionary names = new PDDocumentNameDictionary(pd.getDocumentCatalog());
PDEmbeddedFilesNameTreeNode efTree = names.getEmbeddedFiles();
Map<String, COSObjectable> existedNames = efTree.getNames();
System.out.println(existedNames);//Print Embedded-Filenames to console
pd.close();
I don't know if it is even possible to print the content of a MAP to console. I'm coding in eclipse which doesn't give me any errors. But when I run the jar File I get always: NullPointerException at org.apache.pdfbox.pdmodel.PDDocument.getDocumentCatalog(PDDocument.java:778)
Any ideas or help? Many thanks...

Finally found a solution. For anyone with the same problem, the following code worked for me:
PDDocument pd;
File input = new File(inputfile); // Input File
pd = PDDocument.load(input);
//Writes all embedded Filenames (from pdf document) into Logfile
try{
PDDocumentCatalog catalog = pd.getDocumentCatalog();
PDDocumentNameDictionary names = catalog.getNames();
PDEmbeddedFilesNameTreeNode embeddedFiles = names.getEmbeddedFiles();
Map<String, COSObjectable> embeddedFileNames = embeddedFiles.getNames();
//For-Each Loop is used to list all embedded files (if there is more than one)
for (Map.Entry<String, COSObjectable> entry : embeddedFileNames.entrySet())
{
//You might need to configure the logger first
logger.info("Inputfile: " + inputfile +"Found embedded File: " + entry.getKey() + ":");
}
}
catch (Exception e){
System.out.println("Document has no attachments. ");
}

}

why you comment this line out?
//TrajetModel trajet = new TrajetModel();
I see no other line where you create the TrajetModel.
If that object is not initiated you get the NPE here:
trajet.setNom(aeroport.text());

Easiest way to export longitude and latitude data stored in a SQLite database to a file so it can be imported to a Google Map API through a website?

I have created an application that records a series of longitude and latitude values in a SQLite database and display them as a coloured track on a MapActivity.
I now want to be able to export this data somehow (preferably to a file) so a user can upload the values to a website showing a Google Map API.
My question is: what would be the quickest way to export the data (and in what file format: GPX, XML, CSV) to the SD card located on the Android device.
Many thanks.

Ok Just add this class in your Android Project (with your respective modifications)

instatiate DatabaseAssistant Class

Do you want export data??? so...
DA.exportData();
;) hope this help!
