java - Can we use PrintWriter Class for saving a string in a file in an Android App? If yes, then how? -


if can use printwriter class in making android app, mistake in following code? app stops working on pressing button 'save'

public void save(view view)     {         text=data.gettext().tostring();         printwriter writer=null;          try {             writer=new printwriter(filename);         } catch (filenotfoundexception e) {             msg.settext("filenotfoundexception");             }         writer.print(text);         writer.flush();         writer.close();         msg.settext("data saved successfully");     } }

this should trick. instead of creating file yourself, let android it. 

    text=data.gettext().tostring();     printwriter writer=null;      try {         fileoutputstream os = openfileoutput(filename, context.mode_private);         writer=new printwriter(os);     } catch (exception e) {         // log exception         }     writer.print(text);     writer.flush();     writer.close();     msg.settext("data saved successfully");
