Save a XML file in Android

toorgmot

Hello,

I am trying to save some data on the phone, for when the user closes the app. I thought the best way to do this is via XML (correct me if I am wrong).

So it works fine in Java mode, but when I switch to android it doesn't.

XML xml = loadXML("database.xml");
    XML amount_tot_liter_xml = xml.getChild("amount_tot_liter");
    println(amount_tot_liter_xml.getFloatContent());

The database.xml is inside the data folder. I can read data from the file. But I can't save data:

    xml.removeChild(amount_tot_liter_xml);
    amount_tot_liter_xml = xml.addChild("amount_tot_liter");
    amount_tot_liter_xml.setFloatContent(amount_tot_liter);
    saveXML(xml, "data/database.xml");

using the XML examples from docs (java mode) && modifying it for android (which has a lot of other ways && libs to do that) :: try this code

        import java.io.FileOutputStream;

        import android.content.Context;

        // The following short XML file called "mammals.xml" is parsed 
        // in the code below. It must be in the project's "data" folder.
        //
        // <?xml version="1.0"?>
        // <mammals>
        //   <animal id="0" species="Capra hircus">Goat</animal>
        //   <animal id="1" species="Panthera pardus">Leopard</animal>
        //   <animal id="2" species="Equus zebra">Zebra</animal>
        // </mammals>

        File[] listOfFiles;// this is for showing what happens
        String files; // the same

        XML xml;
        XML xml2;
        File mon;


        void setup() {
          xml = loadXML("mammals.xml");
          XML firstChild = xml.getChild("animal");
          xml.removeChild(firstChild);
         mon = getActivity().getFilesDir();/// INTERNAL storage dir

          saveXML(xml, mon + "/subset.xml");
          verifie();
          xml2 = loadXML(mon + "/subset.xml");
          println(xml2);
        };




        public void verifie(){// for showing....

          String directory = new String(getActivity().getFilesDir().getAbsolutePath() );

        File folder = new File(directory);
          listOfFiles = folder.listFiles(); 


          for (int i = 0; i < listOfFiles.length; i++) 
          {

          if (listOfFiles[i].isFile()) 
          {
          files = listOfFiles[i].getName();

          System.out.println("i=====" + i + "    " + files);
         }
         }



        }

        // Sketch saves the following to a file called "subset.xml":
        // <?xml version="1.0"?>
        // <mammals>
        //   <animal id="1" species="Panthera pardus">Leopard</animal>
        //   <animal id="2" species="Equus zebra">Zebra</animal>
        // </mammals>
