can you please tell what is this error ? thanks.

How did you setup Android?
What fif you set in AVD device when adding new device?
What are your pc specs and OS?

okay! i have download the full pack of android bundle from offical site of android. lemme give the link so as to tell you. http://developer.android.com/sdk/index.html

secondly, i am using windows 7 ultimate with 2 GB ram and 500 GB hard disk.

i have just downloaded that bundle from that link and run eclispse from the folder in the unzip form of that unzip file downloaded. then i just follow the tutorial give on the same site and run the app accoringly. and when i run that app, though it is running but it is giving me the errir again and again. thanks.

thridly, i have used the default settings while making the AVD. 512 MB ram and google nexus and suitable name needed while making that AVD. thanks.

That 2GB is not enough, I have 8GB and Windows is claiming almost 2GB any time. Basically your OS and emulator are fighting over RAM where OS obviusly wins becuase has higher priority.

are you sure in this the problem ? i have friends working on even 1 GB ram ?

Well head over stackoverflow and see for your self

means ? stackoverflow.com ? can you give me link ? actually, it work so slowly, when i made any changes and run, it take too much time to run the app. i can't resist if it take 5 minutes for running it single time... please help!
