[android-developers] Urgent : GPS timeout in android
Hi, In blackberry, we use a timeout to get the location, so that if it doesnt retun location in that much time period, we get to know. But in Android, there is no concept of timeout, can anyone please tell the alternative, that we can find out that after this much time there is no location update from GPS.

[android-developers] ViewFlipper caching issue
The views are not cached in a ViewFlipper. Is there a way wherein we can get an image of the view and show it to user so that he sees the Ui as we see on Home scrren(when we swipe the previous view also moves along and when we lift our finger, only then the next view is shown completely.) What I want to do is that when the user starts moving his finegr on screen, the view should also move along(create an image of view). I am not getting to do this, as when we swipe the present view goes and next view comes, we do not get both visible when we r moving our finger on screen. Please if anyone gets what I am trying to do, do help me. Thanks, Farha -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Rotation event handling
Hi, you can add these lines in AndroidManifest.xml,
and then in your activity, override this method:-
@Override
public void onConfigurationChanged(Configuration newConfig)
{
if (getResources().getConfiguration().orientation ==
Configuration.ORIENTATION_LANDSCAPE)
{
//do your task
}
else if (getResources().getConfiguration().orientation ==
Configuration.ORIENTATION_PORTRAIT)
{
//do your task
}
super.onConfigurationChanged(newConfig);
}
This worked perfectly for me, hope it does for u too...
