Android Development Step by Step 54: Read the file under the Assets,raw folder

First, read the file under the assets file Products.json

Public String Readassetfile (Context C, String file) {Elapsed profiler = new Elapsed ();        BufferedReader bufreader = null;            try {inputstreamreader Inputreader = new InputStreamReader (C.getresources (). Getassets (). open (file));            Bufreader = new BufferedReader (Inputreader);            StringBuilder sb = new StringBuilder ();            String line = null;            while (line = Bufreader.readline ())! = null) sb.append (line);        return sb.tostring ();            } catch (Exception e) {logutil.i (TAG, "fileutils.getfromassets Exception:" + file);        Return "";            } catch (OutOfMemoryError e) {logutil.i (TAG, "fileutils.getfromassets outofmemoryerror:" + file);        Return "";            } finally {Commonutils.close (bufreader);        Profiler.log ("fileutils.getfromassets:" + file); }    }

Calling Methods

Readassetfile (Testactivity.this, "Product.json");

Second, read the Res/raw folder file Cities.txt

 private void Loadaddressdatanew () {countries = new arraylist<country> ();        InputStreamReader inputstreamreader = null;        try {inputstreamreader = new InputStreamReader (Getresources (). Openrawresource (r.raw.cities), "UTF8");        } catch (Unsupportedencodingexception E1) {e1.printstacktrace ();        } BufferedReader reader = new BufferedReader (InputStreamReader);        String Line; try {while (line = Reader.readline ()) = null) {//third bit is | The string is a country cn| China if (line.substring (2, 3). Equals ("|"))                    {Country country = new country ();                    Country.setcountryid (line.substring (0, 2));                    Country.setcountryname (Line.substring (3));                Countries.add (country); }//Province or State cn_anhui| Anhui if (line.substring (0, Line.lastindexof ("|")). LastIndexOf ("_") = = 2) {state state = new State ();                    State.setstatename (Line.substring (Line.lastindexof ("|") + 1)); if (Line.indexof (Countries.get (Countries.size ()-1). Getcountryid ())! =-1) {Countries.get (Countri                    Es.size ()-1). GetStates (). Add (state); }}//City Cn_anhui_anqing| Anqing if (line.substring (0, Line.lastindexof ("|")).                    LastIndexOf ("_") > 2) {City city = new City ();                    City.setcityname (Line.substring (Line.lastindexof ("|") + 1));                    int stateindex = Countries.get (Countries.size ()-1). GetStates (). Size ()-1;                        if (Line.indexof (Countries.get (Countries.size () 1). GetStates (). Get (Stateindex). Getstatename ())! =-1) {                    Countries.get (Countries.size ()-1). GetStates (). Get (Stateindex). GetCities (). Add (city); }                }                //                }            }        }catch (IOException e) {e.printstacktrace (); }    }
