Domain name won't resolve to an IP address.

 Hello Android Developers,

I am working on a program that will connect to a time server (time-
a.nist.gov), retrieve the timestamp, and place it in a text field.

However, when I create the socket, I get an UnknownHost Exception for
time-a.nist.gov


Some ideas I've gotten to fix it:

1. put the <uses-permission
android:name="android.permission.INTERNET" /> tag right before the </
manifest> tag. I did this, and the change is still there.

2. use the static InetAddress.getByName() function to convert to an IP
address (this still throws the same exception)

When I pass the IP address (129.6.15.28) to the socket constructor,
the program works fine. It only breaks when I use the actual domain
name.

Another note. I have written this program in Java and it works
perfectly fine.

If anyone has any ideas, I'd love to hear them! Thank you!

You could be using DNS which simply malfunction (or your device
got no DNS specified at all - worth checking). Try using other DNS,
or, if you got any domain of your own, delegate something like,

either:

time.mydomain. IN CNAME time-a.nist.gov.

or

time.mydomain IN A 129.6.15.28

and us that domain. However, if the culprit is DNS, it sill may
not solve your problem. Checking how queriers are resolved
(i.e. by using dig tool) could move you forward.

1. Android 2.2, Stagefright, and HTTP Progressive Streaming

Hi:

http://developer.android.com/sdk/android-2.2-highlights.html



On above URL page, there is mention of a new API (Stagefright) for the
MediaPlayer to source from a local file or HTTP for progressive
playback. I was wondering if anyone has used this new API and any code
they can share. Is this HTTP streaming of the similar mold as Apple
Adaptive HTTP streaming?Are there any support for formats such as MPEG-
TS?

Thanks.
