[android-developers] How to minimize/eliminate latency on RTSP/HTTP audio stream playback?...
I've been investigating RTSP and HTTP audio streaming clients and have one major issue thus far: The latency on the audio is quite severe (typically on the order of 10 to 30 seconds). Minimizing the buffer size in order to reduce the latency will produce new issues such as data loss (and crashes my test app too :-( ) Anyone know of some other way of minimizing this audio latency (perhaps even using some other protocol)? I looked into RTP (it's UDP-based) but so far there doesn't seem to be any official Android support for that - at least no working code samples. If anyone has any insight, pls share!

[android-developers] RTP library for VoIP/SIP/RTP on OS 2.2 and below?
I"m looking into writing an app that supports VoIP calls via RTP/SIP. Anybody know if there's an RTP Library that can be used on Android 2.2 and below? SIP is only available on Android 2.3. Any ideas? Thnx. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Any *working* code examples utilizing Android's RTP helper classes (RtpStream/AudioGroup/AudioStream)??
Since Android API 12, RTP is supported in the SDK, which includes RtpStream as the base class, and AudioStream, AudioCodec, and AudioGroup. However, so far I've found next to no documentation, examples, or tutorials to help in constructing *working* code based on these APIs. Does anybody know if/where there are ANY code examples out there? Thnx. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] How to insert a TabHost view inside a ViewFlipper ?
Folks, I was wondering if anyone has been able/knows how to include a TabHost view inside a ViewFlipper view... I've tried various ways to do this but keep getting a NulPtr exception whenever the tabhost object is accessed at startup. It looks like Viewflipper does exactly that : flips *view* objects. It knows nothing directly of the concrete Java classes that are associated with the views so the tab objects are always nulls. Unfortunately, the tabhost needs to be data/object populated before it is ever accessed, so this is the issue. Is this analysis correct? If so, is there any way around this? Or am I doing something wrong? Thanks for any suggestions. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: my rotated bitmaps "unrotate" immediately after invoking setCenter() method
Problem solved. Had nothing to do the 'setCenter()' fn. Problem was with the way I was computing my angle/orientation updates: when the map is recentered, the user's cartesian coords are also automatically shifted, so must use geodesic info instead.

[android-developers] Re: Synchronizing Maps and Map Overlays - ConcurrentModificationException
Let me guess... r u invoking your code from *within* your custom
MyLocationOverlay code ?
I had the same Java exception as you until I moved my overlay updating
code OUT of my custom MyLocationOverlay class.
It seems that MyLocationOverlay also maintains a handle on the
overlays list, so that appeared(at least for me,) to be the source of
the ConcurrentModificationException.

[android-developers] my rotated bitmaps "unrotate" immediately after invoking setCenter() method
It seems that invoking the .setCenter(mygeopoint) method on a MapController object has the side effect of setting the orientation of any rotated bitmaps back to the original orientation. Has anyone else also experienced this? My problem is that I'm writing a map application that needs to rotate an arrow bitmap to point in the direction of the cellphone's motion, and I want to periodically automatically re-center the map so that the user's position does not drift off the map. However, each time I call 'setCenter(mygeopoint)', my arrow bitmap "unrotates" back to its original heading, therefore the user loses the directional information. Anyone found a workaround for this problem? Thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
