Writing an Android library - Using its own custom Application class (getApplication)

Image
By User



I'm writing an Android library and I wish to use a custom Application class, which will be accessible from all of the library's activities (using the getApplication method).





The problem is when I call the getApplication method from one of my library's activities, it returns the application class of the app using my library (and not the custom class I declared in the library's Android manifest).





My current guess (based on this answer and the official documentation ) is that the application using my library must also declare the custom Application class in their Android manifest - which is a problematic solution, since that application can also have its own custom class (and a single app cannot have more than one custom Application class, right?).





Can anyone offer a better solution? (or verify that this solution is accurate)





Any help will be appreciated..

    Nothing wrong with your custom Application implementation and AndroidManifest.xml. The correct way of using your custom Application in code is casting.

    Suppose you have a MyApplication that extends android.app.Application, to get MyApplication instead of Application:

    Boolean runInTest = ((MyApplication) getApplication()).isRunInTet();


    Hope that helps.

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
