[android-developers] Re: Decode MP3 audio data to PCM audio format in android
Hi Robert, Thanks for the reply. How can I start work with native code? I havnt used it anytime now. I am new to it, if you can please help to start with using native code libraries, as I hav found that the native MediaPlayer and MediaPlayerService have the decode function. That it how they take mp3 data and decode it to pcm and then pass it on to the hardware thru the PV multimedia framework. So I want to access that decode function from native MediaPlayer.cpp. Thanks for the help Regards, Purvi On Dec 9, 5:23 pm, Robert Green rbgrn@gmail.com wrote: You're going to want to do that in native code. I'm sure there are some open mp3 decompressors that you will be able to get to compile in C with some adaptations. You probably won't have enough memory to decode the whole thing into ram but you can do portions at a time. I believe mp3s are frame-based so it should work.

My Audio stream plays well but just for say a minute, then it start giving me Command PLAYER_PREPARE completed with an error or info PVMFErrNoResources.

[android-developers] Re: Extremely long DNS lookup (and failure) on T-Mobile network
Hello, I am also facing the same problem. I am using a handler to fetch the data coming from the network request. I am thinking to throw an alert message to the user from my app indicating No Response from Network or Network down or somthing like that so that the user donot see any error and the user himself restart the app or take corresponding steps instead of showing user an error. But I system gets to know that there is no network after all my queries are manipulated and so I dont know where exactly can I handle this error. I am able to made it print in my LogCat error[URL not found] so it doesnot give any Force Close error but I want the user to be notified about this. Can you please comment on this and incase if you can help me out with this? Thanks a lot.

[android-developers] Align tabs horizontally to the left of screen
Hello, I have a TabActivity that display tabs either on the top or bottom as specified of the screen in portrait as well as landscape view. Currectly the tabs are dislayed one row and two columns(for 2 tabs each column as one tab). Now what I require is that when the view changes from portrait to landscape, the tabs should be positioned to the left of the screen like two rows and one column each row with one tab.

[android-developers] Re: You must supply a resource ID for a TextView
Hi,
I had the same problem, it was gone when i removed all the @override
lines above the functions of the SeparateListAdapter.
So try not overriding the functions.
It worked for me.

But I declare it there and then in my runnable i do

This works for other adapters.. Really don't know why this isn't
working.
My listview with headers works, i can see the first header or
sometimes more but when i scroll down it crashes.. When i do for
example
adapter.addSection(test, new cinemaAdapter(this, cinema)); it makes
1 list with 1 header without crashing..
So there must be a problem with generating my header titles :s

I don't see anything obviously wrong with your code. I do notice that
you apparently create the SeparatedListAdapter and then immediately
call setListAdapter with it, whereas the SeparatedListAdapter sample
code creates the adapter, then adds a bunch of sections to it, and
then calls setListAdapter at the end. Could it be that
SeparatedListAdapter doesn't work when it is empty? Have you tried
postponing your call to setListAdapter until after you've added all
the sections?
