public class Fileservice {    private Context context;        public Fileservice(Context context){        this.context= context;    }            public void save(String filename,String filecontent) throws Exception{        FileOutputStream outstream = context.openFileOutput(filename, Context.MODE_PRIVATE);        outstream.write(filecontent.getBytes());        outstream.close();                    }}

String name = ed1.getText().toString();                String content = ed2.getText().toString();                                Fileservice fileservice = new Fileservice(getApplicationContext());                try {                    fileservice.save(name, content);                    Toast.makeText(getApplicationContext(), "儲存成功", 5000).show();                } catch (Exception e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }
