[android-developers] JetPlayer
Is there any way to control a play position of a JetPlayer? This concept seems to be totally foreign to it's api. I have a requirement to use a SeekBar to control a play position of the player, as it's done with the mp3 players. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] AudioTrack - Clicking Proplem
I am trying to resolve the clicking problem while using the AudioTrack. It takes place only when playing the first part of the wave (pcm) buffer when the offset to the write is 0 (zero). track.write(buffer, offset, minBufferSize); It tells me that there is something wrong with the pcm data. Could it be because the wave data, I generate using Audacity, has some header as opposed to the pure pcm which does not? I was looking for the converter tools to generate pure pcm but found none. Applications I found generate only wave data so I am not able to test this assumption. At this point I am sure that filling the buffer is correct. Any ideas?

[android-developers] Bussiness Model
Do you think that the business model based on an application that displays/manages paid content is workable in the android environment? I think it is not due to the application market’s lack of support for the paid content? What I mean is that applications, such as iTunes, can be installed from the market but the paid content, such as mp3s, can not be purchased from the market. So, it would have to be purchased through a service outside of the market, as it is the case with iTunes, which is a well established service. In case of a new service, the user would have to open a separate account with the charge information, which is always a problem, specially when it’s a new service. Also, the service itself would have to manage the financial transactions, which introduces additional complexity. Any thought on the subject? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] File System
I don’t see ‘files’ directory under the /data/data//
in the ddms (in the emulator). I can see the ‘database’ and the ‘lib’
directories. It doesn’t seem to be possible to create it manually in
the ddms so when I manually push the file onto the device it goes
under the application directory, /data/data//
myfile.zip
when I try to open this file from my activity;
ZipFile zipFile = new ZipFile("song.zip");
I get the exception with very little information. What's going on?
Surprisingly little documentation on the android’s file system exists.
I goggled for the info but with exception of some code examples no
documentation could be found. Any links will be helpful.

[android-developers] StartActivityForResult
I am using ListActivities to drill down into a hierarchy; artist,
album and song. One activity per hierarchy. So, from the main
activity I start the ArtistActivity with the StartActivityForResult
method and when the an artist is selected I call the
protected void onListItemClick(ListView l, View v, int position, long
id) {
setResult(Activity.RESULT_OK, results);
finish();
}
to return the results. Than the main activity receives results from
the ArtistsActivity in the onActivityResult method and starts the next
hierarchy’s activity, AlbumActivity, in the same way as the previous
activity, on so on. It works fine except that when calling finish
method the hierarchy activity is removed from the stack. So, it makes
it impossible to backtrack to the previous hierarchy since it’s not
there anymore. For example, I can’t backtrack from AlbumActivity to
the ArtistsActivity since it has been removed from the stack. My
question is; is there any way to leave the hierarchy activities on the
stack?

[android-developers] Re: AudioTrack - Clicking Sound
After, repeated effort at sound synthesis I have decided to go back to pre=generated sounds. It's much too computationally expensive. My question is; does AudioTrack use pure pcm of it uses wave. I have this clicking sound and I think it's because I am using wave and the wave is pcm plus same header data. Maybe this header causes the clicking sound.

[android-developers] Custom Layout
What's the deal with the custom layouts? I implemented a custom layout class and began defining xml layout using my new class. Than I realized that I can't just add the child views that way one can add views to the predefined layouts. I had to do it manually modifing the xml. Than I found out that the onMeasure/onLayout methods were getting wrong getMeasuredHeight/getMeasuredWidth results. Why??? (I realy feel like cursing here but what's to point.) On the other hand, If I do all of it programatically, instantiate the layout object in the activity and add the child view to it, all works fine.

[android-developers] Re: AudioTrack stop/release
Thanks Olivier, It is very helpful Olivier, I am just curious about MP3 players, They are able to stop playing with a very small latency. It seems like they would have to repeatedly write into a very small buffer. Do you think that is the case? My scenario is very similar to the MP3 players. I don’t know when the stop action is going to take place so writing zeros might not work. So the only solution is to use small buffer. I will see how it goes.

I've been trying to resolve the issue of the immediate termination of the AudioTrack played in the MODE_STREAM track with no avail. To do so I call stop and release; audioTrack.stop(); audioTrack.release(); audioTrack = null; I tried flushing but it made no difference.

[android-developers] Multiplayer - Multicast Group
In the multi-player setup, every device joins the same multicast group and every device is a broadcaster as well as a receiver of the multicast messages. So, when a device sends a message to the multicast group (for example, a description of the aviator's move) for others to update their game status, this message comes back to the original device. Is there any way to prevent the pockets to come back to the original device? I am trying to filter the incoming pockets and ignore those that originated on my device but it is impossible to test it on the emulator (since it doesn’t emulate wifi) and also it's wasteful having to deal with the bogus packets. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Multicast
After some research I realized that the multicast address must belong
to a predefined range of the multicast addresses; 224.0.0.0 through
239.255.255.255. What I am confused about is that a number of
multicast implementation examples used the host address as the
multicast group address, which does not belong to the range thus is
not a multicast. What gives?

[android-developers] Re: Audio options for music app - should I use JET?
It sounds like we are working on a similar application. I have placed the same question not too long ago and have received no definite answer so I ended up experimenting with all currently available choices; JetPlayer, SoundPool and the AudioTracker, in this order. I have rejected the JetPlayer almost immediately. It is much too high level. The SoundPools looked very promising since it does allow you to play concurrent sounds but I also found it too limiting. I settled down with the AudioTrack but, not surprisingly, it has its own limits. It's interface does not support the pitch/rate control but it does allow you to stream raw date which can be synthesized during the run time. The point I am trying to make is that you will have to experiment with all the options and see what works for you. What you need to do is to design your application in such a way (strategy pattern or such) so you can replace one implementation of the sound control layer with the other, as you experiment with the different options. Let me know how you are doing. Good Luck. Roman On Dec 16, 1:43 am, k_day wrote: > Watched the Google I/O talk on media tonight, and learned some > interesting stuff.

[android-developers] Re: Best practice for P2P handset networking
Steve, I am also in need of a p2p framework. I am a little surprised by lack of any development effort in this area. Please, let me know if you would like to collaborate in researching and maybe implementation of a basic p2p framework. Splitting work will get us there faster. If there is anybody else how wants to participate please let me know. It is not a product or a project, just an informal collaboration. Also, if there is anybody at google monitoring this forum, who has any pertinent information as to the status of the p2p infrastructure, please let us know if such development exists.

I have a gallery view with a number of views, each of which fills the display. So there on view of the gallery per display. Also each view is filled with selectable buttons. Similar to the calendar where a view of the month fills the entire display. To go to the next/ previous month one must scroll by sliding a finger across the display. Also, Each month is filled with a grid of selectable days. My gallery works the same. The problem is that when I slide my finger to scroll the gallery the buttons on the view get selected instead. I want to select the buttons only when I touch the screen as opposed to sliding it.

[android-developers] Re: AudioTrack - Clicking Sound
Niko, I have redone all the test pcm files using the Audiocity and the click is still there. Maybe it’s the driver. I have my development environment on a virtual server. I am creating the track in a static mode so there should not be any gaps. since it’s one track per pcm. I will keep digging. I have one question; do you have any performance experience with manipulating the pcm date at the run time with regard to the data synthesis, such as changing the pitch at run. I would hate to spent time to find out that it not on the current platforms For example, I need pcm data representing a C note in octave 3 and octave 4. I can do it two ways; 1. have two separate pcm files, or 2. have one pcm data representing the middle C in octave 4 and than manipulate the pitch to create the C in the lower octave.

[android-developers] PCM Data - Frame Count
I am using the length of my PCM data buffer to calculate the number of
frames; depending if its mono or stereo or 8bit or 16bit.
For example, if it is a mono/8bit then the number of frames is the
length of the buffer. if it is stereo/16bit the number of frames is
the length / 4.
The problem is that the buffer, I create by reading the PCM raw
resource (file), seems to be too long (look below) . Therefore the
number of frames is also too heigh. why am I getting the buffer longer
then it should be?
there is another way to calculate the number of frames;
Number of Frames = *
for example 11.025[kHz] * 4000 [ms] = 44100 [frames]
the above calculations should yield the same result, yet they don’t
(the problem is with the buffer length). I am certain that the second
result is correct. am I doing something wrong with the way I read in
the data? I should put it into the WHILE loop when reading. But that’s
not it.
Here is how I create the buffer;
private byte[] readResource (int resourceId)
{
InputStream inputStream = null;
byte[] inputBuffer = null;
try
{
inputStream = _Context.getResources().openRawResource
(resourceId);
inputBuffer = new byte [inputStream.available()];
inputStream.read(inputBuffer);
}
catch (IOException e)
{
Log.e(this.getClass().getName(), String.format("readResource:
Exception: %s", e.getMessage()));
}
finally
{
try
{
inputStream.close();
}
catch (IOException e)
{
Log.e(this.getClass().getName(), String.format
("readResource: Exception: %s", e.getMessage()));
}
}
return inputBuffer;
}

Is the AudioTrack fundamentally designed to be a singleton? Methods on the OnPlaybackPositionUpdateListener receive just one argument, which is the AudioTrack itself.

thanks Kumar, that's exactly what I am doing but the problem is that I am getting the convertView as null all the time. Not once did I get the convertView not null (did you ever encounter such problem before). Otherwise, the adapter works fine. Even so, the inflate step is very expensive. It would be nice if I could inflate once in the constructor and then clone the inflated view in the getView as needed (when the convertView is null). Wouldn't it be nice?

[android-developers] Inflator
In my custom adapter, that implements the BaseAdapter and its getView, I use the inflator to generate a new view from a layout. Is there any way to avoid repetitive inflation step? specially when the convert View (an argument to the getView) is always null, which mean it can’t be reused and the view needs to be re-inflated.

[android-developers] Custom Adapter
I have implemented a custom adapter the extends from the BaseAdapter and implements the getView method. It works fine except for one thing, not once do I get the convert View (a parameter to the getView method) that is not null ( that can be reused).

[android-developers] Re: Socket refused connection
Pierr, the following is a question to your question, as well as to anybody willing to share the experience with network connectivity. Do you have any tips regarding the P2P implementation in terms of getting IP address information of the connection target devices (a friend's device, for example). Security setup and any other info you care to share. Can contact information be used in any way to infere the ip? I have implemented the udp client/service, both on the emulator. It works fine.

[android-developers] Include Button
A have a Button with a selector (drawable) assigned to the Button’s background. The selector is used to change the background on touch event.

But it works fine when the Button is placed directly in the main layout. Any ideas? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Attributes represented by expresions
is it possible to define an attribute value of a height attribute, for example, relative to its parent's height. For instance, I want the linear_layout's height to be 2/3 of its FrameLayout parent. I have a FrameLayout with two linear_layouts. The first linear_layout fills the entire FrameLayout and the second linear_layout overlaps the first but only 2 / 3 of its height.

[android-developers] Need Help with the android:weightSum and layout_weight attributes
I have a simple horizontal linear_layout with bunch of image views in it. the trick is that the views have different widths, relative to the size of their parent (the linear layout). I set the layout's weightSum to a 100 and the layout_weight to let's say 10 of one view and 15 of the other, on so on. And it did not work. I also tired using float values setting the weightSum to 1.0 and the layout_weight of the image views to 0.2 and 0.3 and so on. But it didn't work either. I did search this group for any references to the weightSum but found nothing. Any ideas how to handle it? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] comments on the 'Integrating Application with Intents" blog
I would like to make a few comments on the 'Integrating Application with Intents ' blog posted on the developers.android side. Specifically, as to the definition of the reserve action and the data specifications. Neither of these specifications are generic and exhibit a very narrow view of the reservation concept. The restaurant reservation concept should be abstracted as it will have a multitude future implementations in terms of activities and services by other vendors. Action specification presented by the OpenView, "com.opentable.action.RESERVE", incorporates 'opentable' in its namespace. Such common actions, as it is with the restaurant reservation action, should avoid any proprietary names and strive to define a standard action specification that can be used by other activity implementations of the reservation functionality. The generic approach to these specifications should be a driving force for all of us. An example of a generic action specification could be; ACTION SPECIFICATION: "action.RESERV", CATEGORY SPECIFICATION; ''service.food.restaurant". Data specification; as defined by the OpenTable, also violates basic URI format specification; "reserve://opentable.com/2947?partySize=3". The first element of the URI specification should be a protocol specification, 'reserve' is an action name and not a protocol name. The action should be defined in the argument part of the data specification. The domain name should also be a generic name since we do not want to target a specific implementer of the reservation activity. For example; “http://android.com/size=3? datetime=09-11-2009T12:30” . In cases when we do intend to invoke activities implemented by a specific party we should be using a CATEGORY SPECIFICATION; "manufacture.software.company.name.OPENTABLE" or such. This message is not intended as a criticism of the proposed specifications. It is a way to point out a generic nature of abstractions implemented by many activities and the necessity of using generic action, category and data specifications. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
