hey thanks for bearing with me....one final question snoopy...which version of eclipse r u using...i am using eclipse 3.6 which is known to have some issues with android...

by d way thanks a ton

am using Eclipse 3.5.1
Good luck

hey really appreciate ur help ....nothing has worked so far...i really dont know what is the problem??

@schofeild
It might be obvious linux savvy folks, but trying to access localhost or 127.0.0.1 with the android emulator in order to access a local server for testing won’t get you anywhere. That’s because the IP is used internally by the undlying linux as you might have guessed.

Luckily there’s an IP you can use to achieve hitting your local apache/tomcat/whatever : 10.0.2.2

in my case :
public static final String KEY_121 = "http://10.0.2.2:8888/getAllPeopleBornAfter.php";
it Finaly works for me

Hey schofield, I was having the same problem. It was a little complicated to fix. I checked my logcat and is was showing a NetworkOnMainThreadException. Basically, it didn't like me having a network connection in my main UI Thread (http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html). You must either use a handler or a AsyncTask<> object. Check out this site for tutorials (http://www.vogella.de/articles/AndroidPerformance/article.html). I used the Async method and just put everything from getServerData(String) inside the doInBackground(String[]) method. I'm still having problems with ConnectionTimeout, but at least I feel like I'm getting closer.

hey i've got the same probleme,all you have to do is to erase
<uses-sdk android:minSdkVersion="11" /> From the android manifest
and don't forget to insert : <uses-permission android:name="android.permission.INTERNET" />

don't need handler or a AsyncTask<>

hey guys thanks....i finally was able to run the application..there seem to be some issues with my pc...when i ran the same code om my laptop i got the output...strange!!

@mo5ito
I figured there was a way to revert (ie...deleting sdkversion11). But I really dislike going backwards. Plus I think it's best practice to do database calls in a thread other than the main UI anyway. Otherwise you might eventually run into the ANR dialog. View best practices to avoid mentioned here: http://developer.android.com/guide/practices/design/responsiveness.html

Thanks All. This has been an extremely helpful tutorial.

hi there......i try to connect my app to the database on my host...and yes it works, when i try to display some of my data eg: username using textview it works too, but the problem is when i try using list menu to display the name it doesn't work, could you please help me with this....

Hi whitehat,
thanks a lot for the tutorial.
It is work, but only at my device (samsung galaxy spica i5700).
when connected to emulator, it is not work? any idea why?
in emulator i'm sure the internet working, as i can open google from web broswer.
the emulator not show any error, just show http://xx.... (i think is the KEY_121 string)

Thank you very much for the tutorial.. It's very useful

I've just use this code but it only show the value of string KEY_121 in my emulator
in my case is :"http://localhost/people.php"
someone help me?

hey if u r running it on an emulator using local host then you have to use special network alias 10.0.2.2 instead of using localhost....so ur url should look like this:

http://10.0.2.2/connectivity/proj.php (connectivity is the folder name and proj.php is ur file)

hope this helps

after hours i can run it but it still appear (the value of string KEY_121)
i'll try to get only name or id but it still appear all (include id, name, sex and birthyear)
alright, i'll try for another prj
thanks for the tutorial! so great!
