[android-developers] Mechanism for collecting UDP Data
I'm trying to figure out a means to collect UDP packets as they come in. I have been able to successfully collect one packet using AsyncTask but it's not clear how to make this happen on an ongoing basis. I cannot see an obvious means to generate a callback when a packet arrives so I assume this is done by some means of polling. I tried using classes like ScheduledThreadPoolExecutor and creating a new thread but in all cases even though I'm trying to access the UDP buffer in another thread I'm getting the exception (cannot recall the exact name but it refers to trying to do network operations on the main UI thread). One way to make this work would be to run an AsyncTask on a timer but can anyone suggest why I may be having this issue or some ways to make this work. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Support for video streaming over RTP
Is this something that is supported? A quick search shows a class RtpStream but it does not seem to do a whol lot. There appear to be other classes which make use of RtpStream for streaming audio but nothing that I can see for playing video. Has anyone been able to receive rtp streams and play it on MediaPlayer. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Forcing an item in a GridView to remain highlighted after clicking
Okay thanks I will look into what you suggest. I did try the setEnabled() method as well as setSelected() method among other things and they all had no effect. I assumed the item would assume the default behaviour in terms of selected color. But I will try explicitly specifying that and see if it works.

By state, I mean, your item could be 'Checkable' (i.e. only a single item in the whole GridView can be checked at a time) and then when it's tapped, set it to checked, and the appropriate value in the selector would be chosen. Alternatively, you could use the item's .setEnabled() method and do something similar. You may also need to be aware of the android:duplicateParentState attribute.

[android-developers] Re: No Video but audio present when using MediaPlayer on the emulator
Okay I got it done using the DDMS file manager. I have to say your original thoughts about reasons for the video not playing is absolutely correct. With your app I can also hear the audio but cannot see any video. I can also see the all the control buttons and the progress bar. I do not get the control buttons on my app but in my app I'm using the MediaPlayer directly - not through MediaController. I guess I will need to move to using a real device.

[android-developers] Re: No Video but audio present when using MediaPlayer on the emulator
Does anyone have any sample code for playing video. Although it could be emulator using the debugger it seems like the window is not even being created even when the Mediaplayer is turned off. I'm using a class I extended from VideoView. The surfaceCreated method does not ever get called. I'm using this view within a GridView and I cannot get any response from the OnClicked handler in the GridView. It works fine for other objects in the GridView. A working sample would be very useful to help me see what is going on. As a sidenote I have a 3.6GHz Quadcore PC. Does the emulator make use of the multiple cores?

[android-developers] Seekbar button separating from slider
Hi everyone - I'm using the seekbar for the first time within a RelativeLayout. When I try to reposition the bar using LayoutParams and setPadding the bar does move as expected but I also see the button moving apart from the progress slider. I'm unclear what is going on. Has anyone else seen this? Also I need a vertical seekbar. setRotation(90) seems to work but it is very hard to get the slider to move. Again I did not see any obvious way of creating a vertical seekbar. Any suggestions/insights would be welcome. -- You received this message because you are subscribed to the Google Groups Android Developers group.
