How to write a file in Android/Java? -


i try write text file cannot view file, , not write.

the bit of code focusing on @ moment is:

string file_name = ".txt"; string title = ed1.gettext().tostring(); try {       fileoutputstream fileout=openfileoutput("mytextfile.txt", mode_private);       outputstreamwriter outputwriter=new outputstreamwriter(fileout);       outputwriter.write("job title");       outputwriter.write(ed1.gettext().tostring());       outputwriter.close();       toast.maketext(getbasecontext(), "file saved successfully!",       toast.length_short).show();     } catch (exception e) {       e.printstacktrace();     } 

here errors coming out of logcat:

please tell me doing wrong! tried view files on computer phone app is. but, no files saving phone's internal storage.

 string file_name = ".txt";   string title = ed1.gettext().tostring();  try {         fileoutputstream fos = openfileoutput(file_name, context.mode_private);         objectoutputstream of = new objectoutputstream(fos);         of.writeobject(title);         of.flush();         of.close();         fos.close();     } catch (exception e) {         throw new runtimeexception(e);     } 

try this
