Answer 1

To fix the API level warning, check uses-sdk element.

The failure seems to be caused by a disconnected device. Remember that you should allow USB debugging.

Answer 2

Try the steps recommended in the documentation: Eclipse isn't talking to the emulator

Let us know if that works. There are several more things that can be done if that doesn't work.
