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.

Answer 3

Please:

1. Open the SDK manager
2. Then download the latest APIs and API Tools from here
3. Then you need to start new AVD using one of the downloaded APIs
