android - Parsing XML results in SAXParseException with Unexpected End of Document -

i running strange error trying parse xml android device. strange parsing xml worked several days before , have not touched code. today, loading xml not work.

the xml files located in "assets" folder in project directory.

here part passing path of specific xml file parser called mazefilereader.

private void generatefromfile() {     log.v(tag, "generating file");     file maze_file = new file(getcachedir() + "/" + pregen_maze);       if (!maze_file.exists()) try {          inputstream = getassets().open(pregen_maze);         int size = is.available();         byte[] buffer = new byte[size];         is.read(buffer);         is.close();           fileoutputstream fos = new fileoutputstream(maze_file);         fos.write(buffer);         fos.close();       } catch (exception e) { throw new runtimeexception(e); }        mazefilereader mazefilereader = new mazefilereader(getapplicationcontext(), maze_file.getpath()); 

here mazefilereader taking path , trying parse it.

private void load(string filename) {     try{          file fxmlfile = new file(filename);         documentbuilderfactory dbfactory = documentbuilderfactory.newinstance();         documentbuilder dbuilder = dbfactory.newdocumentbuilder();         document doc = dbuilder.parse(fxmlfile); //fails here         doc.getdocumentelement().normalize();          nodelist nlist = doc.getelementsbytagname("maze");          (int temp = 0 ; temp < nlist.getlength() ; temp++) {              ...         }     }     catch (exception e) {          e.printstacktrace();  

i've traced error , seems in line of code executes in documentbuilderimpl

if (parser.nexttoken() == xmlpullparser.end_document) {             throw new saxparseexception("unexpected end of document", null); } 

also, don't think there wrong xml file either have not touched , working several days before. have 4 or 5 other xml files have worked, today, run same saxparseexception reason. possible reasons saxparseexception? possible filepath xml incorrect?

here xml in question:

<?xml version="1.0" encoding="utf-8" standalone="no"?> <maze>      <sizex> 4     </sizex>      <sizey> 4     </sizey>      <roomnum> 0     </roomnum>      <partiters> 60     </partiters>      <cell_0> 173     </cell_0>      <cell_1> 132     </cell_1>      <cell_2> 140     </cell_2>      <cell_3> 198     </cell_3> </maze> 

edit: found weird. checked out old version of project , still not work. made new emulator , reinstalled app. works!!! reason behind this?

i've discovered else. xml file run saxparserexception if debug , step through parsing. file unable parse on. however, if not debug , reinstall app on new device, xml parses correctly. btw, xml located in assets folder. why android exhibiting sort of behavior?. xml files somehow getting corrupted?
