I am testing the Emulator that comes with Android SDK 2.1, but I am Unable to install app from Android Market.
I made the Login on www.google.com but still no success: This is the error message:
Não há telefones Android associados a esta conta. Faça login com uma conta diferente.
There are no Android telephones associated to this account. Do Login with a different account.


Settings -> Accounts and syncand see if it's listed. And by testing the SDK, do you mean the emulator? We have questions on getting the Market on the emulator, just search :) – Matthew Read♦ Jun 8 '11 at 0:53
