[android-beginners] Re: Having trouble with setDataSource() for MediaPlayer
Hi -- I sorted out my problem. I found the answer in someone's blog. it turns out that I have to pass the startOffset and the length to the setDataSource(), and those are obtained via the AssetFileDescriptor: AssetFileDescriptor afd = getAssets().openFd(fileName); mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength()); That does the trick On Jun 30, 11:15 pm, appsgrrl bettyoch...@gmail.com wrote: I've gotten the MediaPlayer to work with the create() on a resource.

[android-beginners] Re: onHandleIntent(Intent) method does not get called
Hi -- Okay, I got further! Yay! It turns out that I also had to call super.onCreate() to avoid the null pointer exception. So, if I call super.onCreate() and super.onStartCommand(), my onHandleIntent() does get excecuted. Now, my new mystery is why my service gets an onDestroy() call right after it is started. I return START_STICKY from onStartCommand, but that does not seem to have an effect. I guess I need to understand the life cycle stuff a little more.

I assume that I use my incoming arguments and pass them to the super.onStartCommand(), correct?

[android-beginners] Re: My first post -- ArrayAdapter question
Hi -- thanks for the response. I don't have any TextView in my layout, which is why I was confused. I was trying to get this to appear as the list for stuff for my spinner, and I ended up using android.R.layout.simple_spinner_dropdown_item for the resourceID and that worked, so now I'm trying to understand that a bit more. On Jun 12, 1:41 am, Yuvi yuvidr...@gmail.com wrote: The textViewResourceId is actually the id of a layout (as it says on the docs: The resource ID for a layout file containing a TextView to use when instantiating views.). So you should have a layout with a single TextView and it should work.
