I am trying to compile my program in android and its not working. The problem is in the "adb". The message which is shown is "The connection to "adb" is slow."
Since this question is a little too broad, and from your comments it seems that you sometimes have it working, make sure you follow these steps from the official documentation.
From your comments it looks like once you started eclipse and have adb connected, the server isn't terminating properly. You can also open a new command prompt and run 'adb kill-server' to make sure the connection is properly closed.
Please also check this solution in another SO question that seems to have the same issue as the one you're having: Stack overflow question
