Dúvida no Ex. 8 da Aula 1 - Criando o Jumper

Boa tarde Bruno,

Qual erro aparece no console?

Aparece isso:

[2016-04-18 22:00:19 - Jumper] New emulator found: emulator-5554
[2016-04-18 22:00:19 - Jumper] Waiting for HOME ('android.process.acore') to be launched...
[2016-04-18 22:00:35 - Jumper] emulator-5554 disconnected! Cancelling 'org.poo.projeto.jumper.MainActivity activity launch'!

Quando eu mudo nas configurações de "Run as" e ponho pra ele rodar com AVD compativel, ele nem abre o emulador e aparece:

[2016-04-19 18:56:08 - Jumper] Android Launch!
[2016-04-19 18:56:08 - Jumper] adb is running normally.
[2016-04-19 18:56:08 - Jumper] Performing org.poo.projeto.jumper.MainActivity activity launch
[2016-04-19 18:56:08 - Jumper] No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD.

Estou usando a API 15 e tentando rodar o emulador da API 15 (Ice Cream Sandwich)

Nessas mensagens que vc colocou não mostra nenhum erro, só que foi executado o projeto. Na segunda tem falando que não achou um emulador compativel.

Não aparece nenhum stacktrace de erro?
