Hello All,
I am new to the Android technology, i need some help in implementing google maps. My problem is:
I want to use google map search in android.
For example if i type restaurants in the below url in the ie eplorer, the map will open with markers.
http://maps.google.com/maps?hl=en&q=restaurants&um=1&ie=UTF-8&sa=N&tab=wl
How can i do this in android using google api's.
Thanks in advance,
Poornima

By the looks of it you have to sign up:
http://code.google.com/android/maps-api-signup.html[^]
OR:
You could have a look at this: http://code.google.com/apis/maps/documentation/staticmaps/[^]
And you could easily use this code once you look at the examples (you could simply download the map image, and then diplay the image). I've done a bit of work with this for desktop machines, it's fairly straight forward to do. (And at least this way you won't have to sign up to anything).
See if you can crack this: fb29a481781fe9b3fb8de57cda45fbef

Hello Chris Maunder,
Thanks for the mobile zone and Thanks for the Newsletters from CP. I am really happy for this Zone. I am looking for some good development videos and tutorials for Windows Phone 7. Anyway I got all in One.

Hi
I have a general type of question. I have an IP camera which supports 3GP container(3GPP file format) video streaming. I need to show the feed from that camera in a windows mobile app(using .NET CF). Does anybody have any experiencies with this type of programming? Any help (links, documents, sample code, advices ...) will be appreciated.

Hi,
I need some help. My programme doesn't show the value of the sensor movement. There's no error in the code. So I'm not sure what to do. Thanks in advance.

Hi All,
I am new to Andriod Development, and i am using Eclipse java IDE.
i am having troubles when i edit any files. The application is working fine unless each time if you need to change in any of the layout files or manifiest. (baiscally the XML files) it always troubling me 
just generating a empty of the file name with an "out" extention. example main.out.xml.
then i have do delete the file and uload/load project manytimes and then it will come back to normal. this problem making me nurvois to change any files.
can anybody tell me what is exactly the cause of this problem?
thanks

Hi,
at last i found the solutions in one of the forums
ye but its still a bug. pretty amazing this survived beta.
forums i read said you need to:
1) delete the main.out.xml file
2) close all layout files
3) select a .java file or the project node and then try to run
nup. Still didn't work. I finally found out, purely by accident, that you also need to delet the compoile error that appears under the problems tab.

Hi everyone,
I not really good with programming, so I need some help. Does anybody know how to create a stopwatch for an Android phone using Java programming? Thanks in advance.
|
|
|
|
|
You could store the System.currentTimeMillis() in a long upon a start button press to note the start time. When someone presses stop read the System.currentTimeMillis() again and substract the already stored value from the start. Now you are left with the amount of milli seconds that passed between the two events.

Hi,
I'm kinda new to programming and with not much knowledge on Java. But this is urgent!! I need help in research. I'm need to create a mobile application using Android and Eclipse.
Objectives:
To develop a mobile application that would be able to push help messages in the event whereby the mobile user requires assistance.
Scope of project:
Develop a mobile application that;
A module to detect movements
A decision making module with the intelligence to trigger an alert based on a set of rules
A module to push an alert message to a 3rd party e.g. via the SMS
Any ideas on how I should go about doing this? Thanks.
Best Regards,

Would you post the exception details? That will help to determine the issue.
|
|
|
|

please clear your question to justify it
what is error in this code and what about exception. Mention it
then we can solved it.
