Is it possible to show screen only once when app starts up?

I want to be able to prompt the users to enter the details required for the app only when it starts up for the first time (not other times). These details will be held in a database on the phone.





Would it be better to check the database each time or put these details in a shared preference? Furthermore, is this type of activity even possible on Android?

    Depends on the details really. If it is a large amount of information you might consider using a Database. For just basic identification information, SharedPreferences should be fine.

    If you do use a Database, you might consider loading them into your Application object. This would depend on how frequently you use this information in your app.

    To check for the first start of the app, a SharedPreference is generally used AFAIK.

    Use SharedPreferences or Database depending on the data complexity and its need later on..

    Store a Flag in SharedPreferences and set this when user enters the data.

    Check that shared preferences flag while on your first activity and redirects accordingly(to Details/one time page) if required.

    here even if a user manually deletes data using Settings > Manage app > your app > clear data, Your app will know to get the details then from user....

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.
