android - Open app menu item from webview -


I am trying to start an intention to open a zxing barcode scanner with a link in a webview.

I have created a menu item which launches the Xxing scanner from the menu, when a person hits the menu button on their phone but some tablets do not have a menu button, so I have access to the webwaves Is required.

I have no clue where to begin I thought that there would be a way to add a JavaScript code to the webview, when someone clicks on a link, then that Android: id = "@ + id / scanNow "Or equivalent says something.

Or there is a way to launch for me: 

  case R.id.scanNow: intent = new intent ("com.google.zxing.client.android .SCAN "); Intent.putExtra ("com.google.zxing.client.android.SCAN.SCAN_MODE", "QR_CODE_MODE"); StartActivityForResult (intent, 0); Back true; From  HTML   
   
 
 
 What you probably want There is some JavaScript in WebWebView and can link it to your Android application. For this, you will need to use.  
 Check for more clarification.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
