Android: Does an app only have one Context object -

Android: Does an app only have one Context object -

I'm confused about the concept of class context I think that this Activity is the base class of , but Android Docks also mentions reference to the collection of global information about the Epe Environment. So what are the 3 activities in my app, does it mean that I have 3 different reference items, or do they actually mention 1 unit?

  In addition to this, what is the life span of any subject matter - does it survive till then the last component of this activity is collecting garbage?

  
   To create a reference docs  gives a clue what is going on: / P> 
  By this method, each call gives a new example of a reference object; Context items are not shared, although they share the general condition (resource, classloader, etc.), so the reference example itself is quite light.  
  Because activity examples are often created / destroyed, and one activity is a reference, it makes sense. Context examples are only close to the various bits of an application, which themselves stay for a long time, but the example itself is not.

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.      I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

php - How do I set up pagination for an image gallery with image
thumbnails? -



    I have two tables:    gallery id | Name | Details Image ID | Title | Caption | Gallery ID    By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
