[android-developers] Sound in games
Hi all! I have pretty common question: is there any bug-free way to implement sound effects in a game? Or we only have unpredictable SoundPool with its horrible bugs? Or MediaPlayer that can only play one sound at once and which is not solution for a game at all? In fact, it is disturbing question for numerous developers right now! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

MediaPlayer cuts last few milliseconds in short sounds after first playing, at least with wma files.

At the same time playing mp3 or ogg with MediaPlayer it is too slow for games, it causes lags.

[android-developers] Re: GridView and BaseAdapter position bug
I have exactly same problem. Why do we have 102 values of position
when there is only 100 cells displayed on screen?
position is changed like: 0, 0, 1, 2, 3... 99, 0 - what is the cause
of that? Can someone from google team answer?
That seems to be a bug, very annoying bug. Answer It's not a bug is
not answer! How do you generate position?

It's not buggy. I use the adapters and grid/list-views in my apps and
they work fine. I think they are not designed for your purpose.
e.g. If your adapter has 100 elements and the grid/list-view only
shows about 15 at a time on the screen, the getView is called about 15
times. Sometimes more times, depending whether a little bit (a few
pixels) of the top or bottom child-view become visible or not. Then,
when you start scrolling, getView gets called again and again when
child-views become visible and others become invisible.
Also, seriously consider re-using the convertView for your grid- or
list-view. My experience is that it can really slow down your app if
you just return new View instances for each child-view/cell:
public ... getView() {
View view = convertView != null ? convertView : createNewView(...);
...
...
return view;
}
The implementation of the adapter+listviews does not need to rely on
the order in which the getView is called. As long as it is called for
every child-view that becomes visible.
Isn't is possible to start a child-view's (cell's) animation when you
handle it the getView(...) method?
If you really want at least 100 child-views/cells to be created (i
won't recommend it... it's a LOT), you can override the Adapter's
getViewTypeCount() and getItemViewType(int pos). Even with this, I'm
still not sure if getView would get called in the order you want.
...
private static int EXPECTED_CELL_COUNT = 100;
public int getViewTypeCount() { return EXPECTED_CELL_COUNT; }
public int getItemViewType(int pos) { return pos %
EXPECTED_CELL_COUNT; }

Even with convertView problem is still same - last cell is not

And... you said WHEN getView()... I think it's no matter, matter HOW
MANY times getView() called.
It calls more than 100 times, whats very strange.
For the first time it's called 102 times and all animations was
working. For the second and next times it was 101, and last
animation
was static.
I think where is some bug regularity...

You should ALWAYS reuse the convertView, oherwise you're gonna eat
up
memory and just slow down your app. And like I said, there is no
guarantee on how and when getView() is called so you cannot rely
on it
with your anim counter.
2009/4/27 Illidane illid...@gmail.com:
I dont use convertView parametr and return new child-view.
Each cell has an animation. In the getView I generate an array of
animations, wich I start when the adapter stops his work ( e.g.
when
my mAnimCounter == 102 ( but need be max 100, lol ) When I run
app,
all 100 cells are animated. But when I re-check the field as I
need
and call mGameGrid.setAdapter(mAdapter), new animations working,
but
last. Last cell are NOT animated. Problem can be only in getView
and
method how it works. I very doubt that it's not a bug of
GridView or
Adapter.

We have three times same value of pure the magical-generated position
and the official answer it is NOT a bug. Ok, than I am Al Pacino.
Why not to post algorithm of position generating? That looks fishy...

To Romain Guy:
Ok, I understood that you think that it's NOT a bug and that you
implement it how you want it be.
But I need to say you, that in such situation is very hard, or
sometimes is impossible to write good, stable, beauty, useful and
competitive apps for Android, not only for me, but for all Android
programmers.
And I think you know that.
