android copy folders from assets to internal device app data folder

I created two folders inside assets ("images" and "files") both containing some files. I need to copy it when first launch to data/data/com.relatedPackage.myApp keeping same name and same file contents. I am an iOS programmer and that os does not allow to copy whole folders so, in android, which is the proper method to do it?

Possible to copy whole folder "images" (including its files) from assets to data/...? That would be great.
If not, should I create first empty folders using same names at data/... and then copy files from assets to current? In this case would be necessary to list all files inside folders in order to copy to data/...? Thank you.

Serving different XML content on the same web

I don't know if this is the suitable place to ask this question, so I am sorry if I am doing it wrong. I think this is not a duplicate question. If it is, I am sorry too.

Currently, I have a web app which takes its content from a unique XML document. The URL is "http://webapp.com/"

The problem is that now I have to create a second version of the web which uses a new different XML document, so I have to put them different URLs, something like the following:

http://webapp.com/activities

http://webapp.com/stages

How can I have all my sources on just one directory on server-side (I suppose it's better to maintain, the resources are cached better, etc...) but with these 2 URLs pointing to the folder and making the PHP loades the XML depending on the URL?

I suppose I have to change the .htaccess file to redirect to that folder, but how can I tell what XML I must load? And the user must see on the search bar the URL he used, for example "http://webapp.com/activities"

Can anybody help me please?
Thanks for all

Spring @Transactional does not work in JUnit test?

I am using Spring 3.2 and JUnit 4.

My Dao class is as follows:

@Transactional public class SomeDaoImpl implements SomeDao {

The update operations on this work if executed directly from web application. However, I am seeing that junit integration tests that exercise the update methods do not actually persist the changes. Is something rolling the transactions back when junit methods are executed?

Best practices for API backwards compatibility

I'm working on an iPhone/iPad/Android app which communicates with a JSON API.

The first release of the version of the app is complete, and now additional phases of development are taking place. In the additional phases, the app needs to integrate with a new version of the API and allow the user access to additional features such as new screens or modified behaviour within existing screens. The app does however need to be backwards with previous versions of the API.

What is the best practice for tackling such a requirement?
I could of could do checks throughout the code:

if (APIVersion == 1) {
 
 } else if (APIVersion == 2) {
 
 } else if (APIVersion == ....) {
 
 }...
 

But I'm concerned about the scalability of this approach.
The factory method comes to mind but I'm not sure how far this would get me.

Thanks,
Mark

Extension method in where clause in linq to Entities

In linq to Entities we needed a method that works like "sql like". We have implemented our own extension method to IQueryable, because contains method not work for us because doesn't accept patterns like '%a%b%'

The created code is:

private const char WildcardCharacter = '%';
 
 public static IQueryable<TSource> WhereLike<TSource>(this IQueryable<TSource> _source, Expression<Func<TSource, string>> _valueSelector, string _textSearch)
 {
     if (_valueSelector == null)
     {
         throw new ArgumentNullException("valueSelector");
     }
 
         return _source.Where(BuildLikeExpressionWithWildcards(_valueSelector, _textSearch));
 }
 
 private static Expression<Func<TSource, bool>> BuildLikeExpressionWithWildcards<TSource>(Expression<Func<TSource, string>> _valueSelector, string _textToSearch)
 {
     var method = GetPatIndexMethod();
 
     var body = Expression.Call(method, Expression.Constant(WildcardCharacter + _textToSearch + WildcardCharacter), _valueSelector.Body);
 
     var parameter = _valueSelector.Parameters.Single();
     UnaryExpression expressionConvert = Expression.Convert(Expression.Constant(0), typeof(int?));
     return Expression.Lambda<Func<TSource, bool>> (Expression.GreaterThan(body, expressionConvert), parameter);
 }
 
 private static MethodInfo GetPatIndexMethod()
 {
     var methodName = "PatIndex";
 
     Type stringType = typeof(SqlFunctions);
     return stringType.GetMethod(methodName);
 }
 

This works correctly and the code is executed entirely in SqlServer, but now we would use this extension method inside where clause as:

myDBContext.MyObject.Where(o => o.Description.Like(patternToSearch) || o.Title.Like(patterToSerch));
 

The problem is that the methods used in the where clause have to return a bool result if is it used with operators like '||' , and I don't know how to make that the code I have created returns a bool and keep the code executed in sqlserver. I suppose that I have to convert the returned Expression by BuildLinqExpression method to bool, but I don't know how to do it

To sum up! First of all it's possible to create our own extensiond methods in Linq to Entities that execute the code in SqlServer? if this is possible how I have to do it?

Thanks for your help.

Post JSON to Python CGI

I am looking to post JSON sent by any standard library such as 'JQUERY' using the standard.

$.ajax() post routine with my JSON.

can you tell me if on the page I post to ("saveList.py") this code is correct that will get the resultant json and then return the response as successful.

cheers, I've only ever worked with Django and now raw cgi so im slightly confused.

#!/usr/bin/env python
 # -*- coding: UTF-8 -*-
 
 import sys
 import json
 
 def get():
     result = {'success':'true','message':'The Command Completed Successfully'}
     data = sys.stdin.read()
     myjson = json.loads(data)
 
     self.response.out.write(str(result))

show 1 insted of 01 with PHP pack for Persian numbers

there is a function for converting English standard nums to Persian (Farsi) or Arabic nums:

function farsinum($str){ if (strlen($str) == 1){
$str = "0".$str; $out = ""; for ($i = 0; $i < strlen($str); ++$i) {
$c = substr($str, $i, 1);
$out .= pack("C*", 0xDB, 0xB0 + $c); } } return $out; }

but this function produce 01 02 03 ... insted of 1 2 3 ...
i think something must be change here:

$out .= pack("C*", 0xDB, 0xB0 + $c);

any help appreciated.

Python script - How to set the right server, when I perform request/open of application

Python 3.2.2, I want to check HTTP status code (eg. 200 or 404) on some www application.

There are five servers and each server have a copy of this www application

(The user is automatically redirected to the application on the server with low traffic/sometimes on random server).

Suppose that the name of servers is: 0,1,2,3,4

I tried various options i have tried, three of them I pasted below (they works -always return 200, but choose not this server what I want):

1

import urllib.request,urllib.parse, http.cookiejar
 values2= {"server":"2"}
 data2 = urllib.parse.urlencode(values2)
 data2 = data2.encode("utf-8")
 request2 = urllib.request.Request(url,data2)
 cj2 = http.cookiejar.CookieJar()
 cj2.add_cookie_header(request2)
 urlOpener2 = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj2))
 url2 = urlOpener2.open(request2)
 x2 = url2.getcode()
 

2

import urllib.request
 headers1 = {"Set-Cookie":"server=2"}
 req1 = urllib.request.Request(url, None, headers1)
 t1 = urllib.request.urlopen(req1)
 coderesp1 = t1.getcode()
 

3

import urllib.request
 urlOpener3 = urllib.request.build_opener()
 urlOpener3.addheaders.append(("Set-Cookie", "server=2"))
 url3 = urlOpener3.open(url)
 x3 = url3.getcode()
 

If you have some questions about my problem, please write, I will immediately reply to what you want to know.

Android bitmap out of memory error

I get the famous out of memory error. But i have tried many of the suggested solutions on this problem without any luck. I understand that to prevent a bitmap to exceed the memory, you make a static variable of the drawable (Android docs). But that isn't working in my app because i have so many markers as you can see..

Does anyone have a suggestion to a solution?

for(Poi p : poiarray){
 
                 WeakReference<Bitmap> bitmap = new WeakReference<Bitmap>(p.get_poiIcon());
                 if(bitmap!=null){
 
                     Drawable marker = new BitmapDrawable(Bitmap.createScaledBitmap(bitmap.get(), 60, 60, true));
                 annotationOverLays.add(new CustomAnnotation(marker,p,this,mapView));    
                 //mapView.getOverlays().add(new CustomAnnotation(marker,p,this,mapView));   
                 }
             }
             mapView.getOverlays().addAll(annotationOverLays);

Sending JSON through GET Method in Objective-C

I have a seemingly easy question. I'm trying to send data from my iPad device to a server using JSON. The thing is, all tutorials I see about sending JSON to the server uses the POST method. My question is, is it possible to send JSON using the GET method? It will be really helpful if you can give me some pointers on how to do it. Thanks.

Defining JQuery Function

The two below functions work as scripted except for when i add the Function next () {;} and function prev () {'} around it to define the custom function.

What am I doing wrong here?

function next() {
 
        $('#up').click(function() {
        $("#two").prev().animate({height:'80%'}, 500);
        });
     ;}
 
 
   function prev() {     
        $('#down').click(function() {
        $("#two").next().animate({height:'80%'}, 500);
        });
  ;}
