android - my app consume high CPU -


My app is made up of four tabs: three scenes with a webview and some text / audit ... the problem is my app Consume too many CPUs and I do not understand why, and the main problem is that when the app is turned on (user uses the Home button), my app is still CPU (about 20% Or more!) And battery consumption.

I do not understand what the CPU uses so much, so I have two questions:

  1. How do I properly (with eclipse) process ( Method, activity ...) that use a lot of CPU?
  2. When I press the user's home button, how can I "freeze" with 0 CPU consumption (I think that is in onPause method, I try it with a full (), this work , But when the user returns to my app, he gets FC.)

    Thank you very much!

    Edit:

    It seems that my webview consumes the CPU, how can I stop this webpage without destroying the webview object?

    I am getting the solution:

    The JavaScript content was problematic in the webview. To resolve this: 

      Prevent public null at @Override () {super.onPause (); / * Webview punctuation timer, if not, high CPU during pause * / page.pauseTimers (); }   
     and resume on,  
      resume at public zeros () {/ * reactive timer * / super.onResume (); Page.resumeTimers (); }

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

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...
