I recently switched to a new setup that is reporting PHP Notices; my code has worked fine without these notices being fixed, but I am wondering if it makes sense to fix every one and leave them reported or just ignore them and turn notice reporting off.

What are some different opinions on this? Are there any best practices associated with notices?



Errors are errors. They have to be fixed before your code works.

Warnings are warnings. They warn you that what you're doing is probably a bad idea, even if it works (or seems to work) for you at the moment. So they too should probably be fixed.

Notices are notices. They should be noticed. Hence the name. It may not be a problem that your code generates some, but it's something you should examine and judge on a case-by-case basis.

And of course, it is much easier to notice notices if you don't get 400 of them. So there's a big benefit to trying to eliminate them. It makes the ones you haven't yet noticed become more noticeable.

If this is to terminate lines in an email then it's the spec for email that you need to look at, not what is used on any particular platform.

Lines in email are terminated by CRLF ("rn") according to RFC2821

SMTP commands and, unless altered by a service extension, message data, are transmitted in "lines". Lines consist of zero or more data characters terminated by the sequence ASCII character "CR" (hex value 0D) followed immediately by ASCII character "LF" (hex value 0A). This termination sequence is denoted as in this document. Conforming implementations MUST NOT recognize or generate any other character or character sequence as a line terminator

That seems pretty clear that in an email the end of line is to be sent as rn . Sending anything else might work but it's wrong unless you are using a "service extension" and if you are then you probably know what you should be sending anyway.

You should point to your vendor/autoload.php at Settings | PHP | PHPUnit when using PHPUnit via Composer.

This blog post has all the details (with pictures) to successfully configure IDE for such scenario:

On Mac OS X environment variables available in Terminal and for the normal applications can be different, check the related question for the solution how to make them similar.

Note that this solution will not work on Mountain Lion (10.8).

I'm glad you're already playing with it!

Some things to note: (in lazy bullet form)

  • if this is the worst of your problems, your app's probably in a good spot. :) Writes are generally slower than reads, though, so be sure you're using SharedPreferenced$Editor.apply() instead of commit(). apply() is new in GB and async (but always safe, careful of lifecycle transitions). You can use reflection to conditionally call apply() on GB+ and commit() on Froyo or below. I'll be doing a blogpost with sample code of how to do this.

Regarding loading, though...

  • once loaded, SharedPreferences are singletons and cached process-wide. so you want to get it loaded as early as possible so you have it in memory before you need it. (assuming it's small, as it should be if you're using SharedPreferences, a simple XML file...) You don't want to fault it in the future time some user clicks a button.

  • but whenever you call context.getSharedPreferences(...), the backing XML file is stat'd to see if it's changed, so you'll want to avoid those stats during UI events anyway. A stat should normally be fast (and often cached), but yaffs doesn't have much in the way of concurrency (and a lot of Android devices run on yaffs... Droid, Nexus One, etc.) so if you avoid disk, you avoid getting stuck behind other in-flight or pending disk operations.

  • so you'll probably want to load the SharedPreferences during your onCreate() and re-use the same instance, avoiding the stat.

  • but if you don't need your preferences anyway during onCreate(), that loading time is stalling your app's start-up unnecessarily, so it's generally better to have something like a FutureTask<SharedPreferences> subclass that kicks off a new thread to .set() the FutureTask subclasses's value. Then just lookup your FutureTask<SharedPreferences>'s member whenever you need it and .get() it. I plan to make this free behind the scenes in Honeycomb, transparently. I'll try to release some sample code which shows best practices in this area.

Check the Android Developers blog for upcoming posts on StrictMode-related subjects in the coming week(s).
