I have downloaded android-sdk-windows, there are bunch of folders and files. How could I launch an emulator for my current app, where is says my apps??? It says launch an eclipse...create new project from the existing source which is my app here.So I able to view any modifications as I go alone. thanks in advance...

Also,I forgot to ask another question, every time I make a change do I have to download source code again? That would be not convenient. And where do I look for existing project, after I downloaded a source code, which folder which file.

Have you checked out the faq's and documentation and watched the 'how to' videos? They'll walk you through the basics and give you an understanding of the product.

I have found the Android Emulator to be a real pain! I don't even bother with it anymore, instead I compile the app, upload the .APK to my server, then access the URL of the .APK from my ANdroid phone & download install from there That way I can test my App in realtime on a real device, rather than something trying it's best to emulate your device Make any relevant tweaks and changes in Buzztouch seeing the results realtime, recompiling, re-uploading and re-downloading if necessary (sounds a bit long-winded, but way, way faster than waiting for the emulator to start) Regards Steve
