[android-beginners] HttpClient through wifi OK, through 3G KO
Hi,
I have got a servlet that returns Hello World on each POST :
{
resp.setCharacterEncoding(utf-8);
resp.setContentType(text/plain);
PrintWriter out = resp.getWriter();
out.append(Hello World);
out.flush();
out.close();
}
I have got an HTML page that queries this servlet through an XMLHttpRequest.
Both are deployed on a tomcat reachable on the internet.
I have got my android app that uses HttpClient to reach my servlet
deployed on my Tomcat. It is installed on my HTC Magic.
If I launch it when connected on Wifi : it works.
If I launch it when connected to 3G (GSM data network) : it doesn't
work but my servlet is reached.
Technical problem while receiving response.
org.apache.http.NoHttpResponseException: The target server failed to respond

If I use the web browser through 3G to activate my HTML page, I do see
the Hello World.
How could I debug HttpClient or ask it to dump everything ?
Does someone have a clue on what's going on ?
Thanks a lot,

[android-beginners] Low performance using SurfaceView, touchMode and OptionMenu
Hi, I'm recently working on android application and i can not deal with performance issues. My app is based on SurfaceView, I use separate thread like in lunar lander. My problems starts when i use onTouchEvent and onCreateOptionMenu. I created a test application, which does nothing other drawing FPS on canvas. It shows up to 60 fps, some times 40-50 when i don't interact in it. Another case - i start the same application, i have about 60 fps. Then I open option menu and it slow down to 40 fps, i touch the screen and another drop to about 20 fps. If i stop touch the screen fps increase to about 40 some times 50 but not to 60. Sometimesi have the case that app runs with 60 fps, i start option menu and touch the scren and I have 60 fps as on beginning. I have no ideas why is this happens. If anyone has any idea, please reply. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Cannot enable gears in emulator
Hi all, I am using SDK 1.0_r2 and cannot use google gears in my applications. For example, gears API examples fail to work saying that page is not allowed to use Gears. I Found settings for this in browser settings, but clicking on Gears settings does nothing (I cannot see list of allowed application!). Any ideas?
